To the Owner/Operator/Dealer

This Operator's Manual is an integral part of the safe operation of this machine and must be maintained with the

implement at all times. A Manual canister is provided on the implement where this manual can be properly stored.

If you lose or damage this manual a free replacement manual can be obtained from an authorized Rhino dealer or

by down loading the manual from the Rhino website www.servis-rhino.com

BEFORE YOU START!! READ, UNDERSTAND, and FOLLOW the information provided in this manual, the AEM

Mower Safety manual and the tractor operator's manual carefully to learn how to operate and service your machine

properly. Failure to do so could result in personal injury to you and bystanders. All implements with moving parts

are potentially hazardous. Every effort has been made to ensure that the machine is safe but operators must avoid

engaging in unsafe practices and follow the written instructions provided. The manufacturer has designed this

implement to be used with all its safety equipment properly attached to minimize the chance of accidents.

SAFETY FIRST. Completely read and understand the safety section of this manual before operating this

equipment. Do not allow anyone to operate this equipment who has not fully read and understood this manual.

Contact your Dealer to explain any instructions that you do not fully understand.

The care you give your Rhino Implement will greatly determine your satisfaction with its performance and its

service life. Carefully read and follow the instructions in this manual to provide you with a thorough understanding

of your new implement and its intended use and service requirements.

All references made in this manual to right, left, front, rear, top or bottom are as viewed facing the direction of

forward travel with the implement properly attached to the tractor.

Replacement Parts information is located in a separate Parts Manual. Rhino mowers use balanced and matched

system components for blade carriers, blades, cuttershafts, knives, knife hangers, rollers, drivetrain components,

and bearings. These parts are made and tested to Rhino specifications. Non-genuine "will fit" parts do not

consistently meet these specifications. The use of "will fit" parts may reduce mower performance, void warranties,

and present a safety hazard. Use genuine Rhino mower parts for economy and safety.

For future reference, record your Rhino product model number and serial number.

In order to reduce accidents and enhance the safe operation of mowers, Alamo Group Ag Division, in cooperation

with other industry manufacturers has developed the AEM/FEMA Industrial and Agricultural Mower Safety

Practices video and guide book.

The video will familiarize and instruct mower-tractor operators in safe practices when using industrial and

agricultural mowing equipment. It is important that Every Mower Operator

be educated in the operation of their

mowing equipment and be able to recognize the potential hazards that can occur while operating a mower. This

video, along with the mower operator’s manual and the warning messages on the mower, will significantly assist in

this important education.

Your Authorized Rhino Dealer may have shown this video and presented you a DVD Video when you purchased

your mower. If you or any mower operator have not seen this video, Watch the Video, Read this Operator’s

Manual, and Complete the Video Guidebook before operating your new mower. If you do not understand any of

the instructions included in the video or operator’s manual or if you have any questions concerning safety of

operation, contact your supervisor, dealer or Alamo Group Ag.

If you would like a VHS video tape of the video, please email AEMVideo@alamo-group.com or Fax AEM VHS

Video at (830) 372-9529 or mail in a completed copy of the form on the back of this page to AEM VHS Video 1502

E Walnut Street, Seguin, TX 78155. and request the VHS video version. Please include your name, mailing

address, mower model and serial number.

Every operator should be trained for each piece of equipment (Tractor and Mower), understand the intended use

and the potential hazards before operating the equipment.

The information and material listed above along with this Operator’s Manual can assist you in meeting the OSHA

requirement for Operator annual training.

DEALER to CUSTOMER Pre-Delivery/ Operation Instructions

Dealer should inform the Purchaser of this product of Warranty terms, provisions, and procedures that are

applicable. Dealer should inform Purchaser to review the contents of the Operator’s Manual including safety

equipment, safe operation and maintenance, to review the Safety Signs on the implement (and tractor if possible)

and of Purchaser’s responsibility to train his/her operators’s of safe operation procedures.

• IMPLEMENTS: I have explained that Deflectors, Chain Guards, or Solid Skirts must be installed and main-

tained in good repair.

• DRIVELINES: I have made certain that all driveline, gearbox, and other shields are in good repair and fas-

tened securely in place to prevent injuries from entanglement or thrown objects.

• HYDRAULIC MACHINES: I have explained the necessity of using clean hydraulic oil, changing filters as

instructed, stopping leaks, damage caused by operating with over-heated oil, caring for hoses, using hoses of

proper rating, maintaining the specified operating pressure and the potential hazard of oils penetrating the

skin.

• FOLDING-TYPE IMPLEMENTS: I have explained that it is not possible to guard against thrown objects when

the head is lifted off ground and that operator is responsible to watch out for persons in the area. I have

explained that the lifted mower head or boom can contact overhead obstructions with damage to cables and

telephone lines and possible injury. I have explained that the extended head or boom or retracted boom can

contact power lines resulting in electrocution, injury or death and that operator is responsible for keeping clear

of such hazards.

Know The Rules

Most employers have rules governing operation and

maintenance of equipment. Before you start work at a

new location, check with your supervisor or the safety

coordinator. Ask about the rules you will be expected

to obey.

The Occupational Safety and Health Administration

(OSHA) enforces federal laws within the United

States that apply to safe operation, application and

maintenance of equipment on a worksite. It is the

employer’s responsibility to comply with these laws.

An OSHA representative may periodically inspect a

worksite to see that these laws are being followed.

There may also be local or state/provincial laws or

international regulations that apply to this equipment

and its use, along with speci c worksite or employer

rules. It is important that you know and comply with

all applicable laws and rules, including those requiring

operator training and certi cation.

These are some of the rules you must work by:

— A ROPS and seat belt-equipped tractor is a federal

government (OSHA) requirement for operator

protection during mowing operations. An enclosed

cab provides additional operator protection from

thrown objects. Check your mower operator's manual

to see if a tractor cab is also required.

— Wear and check that others are wearing proper

clothing and personal protective equipment.

— Inspect your machine and attachments before each use

as speci ed by the manufacturer and your employer.

— Know the limitations and operating characteristics of

your mowing equipment. Do not misuse it.

— Have all provided shields and guards properly

installed before operating the machine.

— Never modify or remove any part of the machine

(except for service—then make sure it is replaced).

Mow only in daylight or good arti cial light conditions.

Avoid serious injury or death from mower-thrown

objects or blade contact:

— Keep chain shields,  exible or solid de ector shields

or discharge chutes in place and in good repair.

— Keep bystanders at least 300 ft (92 m) from mowing

operation.

— Never direct mower discharge toward anyone.

— Keep hands, feet and other body parts away from

rotating parts, blades and discharge openings.

— Do not operate mower in transport position.

Do not approach a mower until all motion has stopped.

Mower PTO drive engagement:

— Raise mower to maximum cutting height.

— Engage PTO at low engine rpm.

— Increase engine rpm to mower’s rated rpm PTO speed.

— Lower mower to desired cutting height.

— Stop and shut down immediately if the mower strikes

an obstruction.

— Inspect and repair any mower damage before

resuming mowing.

— Do not operate mower with severe vibrations or with

unusual noise.

Mower-Thrown Objects

Depending on the designed purpose, mowers are

designed to cut grass, weeds, brush and crops. The

mower blades have been designed and tested for

rugged use. The mower blades, however, are not

intended to contact solid objects like rocks, concrete

or metal. Such impact can cause broken objects to be

thrown up to 300 ft (92 m). Bystanders should never

be within 300 ft (92 m) of an operating rotary mower or

within 100 ft (30 M) of a properly equipped disc mower.

Rotating Blades –

Keep Away

Do Not Operate a

Damaged Mower

Operate Safely

Mower shielding is designed to reduce the risk of thrown

objects and must be properly maintained and in place

during mowing operations.

The risk of serious injury or death from thrown objects

can be signi cantly reduced by following three rules.

If all of these safety rules are not followed, the

mowing operation must be stopped if anyone comes

within the safety limit for the mower type.

First — Inspect the area prior to mowing and remove

stones, branches, wire, cable, metal, glass and other

solid objects before operating. Any objects that cannot

be removed must be clearly marked and carefully

avoided by the operator.

In non-crop areas with grass and weeds high enough to

hide objects that could be struck by the blades, inspect

the area and remove or mark large debris or obstacles.

Mow the area at an intermediate height. Inspect the area

closely and remove or mark any remaining debris or

obstacles. Mow again at desired  nal height.

Second — Mower-thrown object shielding must be

used when operating near roads, parks, populated

areas or other areas where thrown objects could

injure bystanders or damage property. Follow the

manufacturer's operator's manual.

Third — Cross diagonally when mowing through

ditches, sharp dips, and drops. Raise the mower to

prevent the mower blades from hitting the ground.

All Mower

Safety Rules

Operate Safely

Mower-Thrown Objects (continued)

Disc Mowers — When using a disc mower it is

important to know the area to be mowed. If the operator

has mowed the  eld before and is familiar with all

obstacles that may be present, it is suf cient to watch

ahead of the mower path for any additional objects that

may have entered the  eld. Be ready to stop or avoid

any objects that could be hazardous if thrown by the

mower. If you plan to mow an unfamiliar  eld and it is

next to a traveled road or people may be within 100

ft (30 m) of the mower you must inspect, and clean or

mark the  eld.

Mowing In Reverse

Do not mow while traveling in reverse. Objects are more

likely to be thrown and can travel further.

Shut off the PTO, wait for the blades to stop turning,

raise the mower, and then back up.

Mow traveling in the forward direction.

Mowing Ground Speed

Proper ground speed depends on terrain conditions and

grass type, density and height to be cut:

— Normal ground speed range is 2 to 5 mph.

— Use slower ground speed for mowing tall, dense grass.

— Use faster ground speed for mowing medium height,

thin grass and under smooth terrain conditions.

— Use slower ground speed for mowing in rough,

sloping or unfamiliar terrain.

Disc mowers are designed to use faster ground speeds

for operating in  elds clear of debris and surface hazards.

Use Proper

Ground Speed

Do Not Mow

in Reverse

Operate Safely

Extremely Tall Grass Mowing

You may need to mow extremely tall, non-crop grass

twice. (See page 13, Mower-Thrown Objects.)

First mowing pass:

— Shut the mower and tractor down using proper

equipment shut down practice before dismounting

tractor. (See page 18, Proper Equipment Shut Down

Practices.)

— Inspect the area and remove or mark debris and

obstacles.

— Cut grass higher (10-15 inches) to avoid hidden objects.

Second mowing pass:

— Shut the mower and tractor down using proper

equipment shut down practice before dismounting

tractor.

— Inspect the area and remove or mark debris and

obstacles.

— Cut grass at desired height and, when possible,

90 degrees to the  rst mowing pass.

Watch Equipment Clearances

Three-point hitch and side-mounted mowers have a

larger turning arc than pull-type mowers. Allow suf cient

clearance for mower swing while turning.

Do not allow bystanders near the tractor and mower

when moving or transporting the tractor and mower.

Wing And Side Mount Mowers Safety Practices

Raised wing positions reduce shielding protection and

increases the thrown object and blade contact hazard

risks.

Avoid possible serious injury or death by thrown

objects or blade contact from raising and lowering

wings during mowing operations:

— Do not mow with bystanders within 300 ft (92 m) of

the mower.

— Be sure no one is near mower while raising or

lowering wings.

— Shut off the PTO and wait for all rotating elements to

stop before raising the mower deck or wing section.

— Only raise wing to clear objects in the mowing path

or to match ground slope.

— Lower raised wing to ground after clearing object or

ground slope conditions.

— Stop mowing if anyone approaches within 300 ft

(92 m) of mowing area.

Ditch Bank Mowing Safety Practices

Use extreme care when mowing ditch banks. Watch for

washouts, eroded areas and mowing obstructions along

the ditch banks. Hitting obstructions with side-mount

or boom mowers may swerve the tractor’s front end

toward the ditch.

Avoid Hitting

Obstructions

Keep Bystanders

— Use enclosed ROPS cabs, special protective

enclosures and other operator shielding available from

the manufacturer when performing these operations.

— Inspect mowing area and remove or mark all foreign

objects and debris to be avoided by mower.

Uneven Terrain Mowing Safety Practices

Tractor and mower stability is reduced on slopes and

uneven terrain.

As in all conditions when mowing, use tractors

equipped with ROPS and seat belt. Make sure the

ROPS are raised and locked in place and always

wear your seat belt.

Prevent tractor and mower overturns and maintain

equipment stability control:

— Review tractor and mower operator’s manuals for

operating safety practices on slopes and uneven

Hydraulic System Hazards

The hydraulic system is under pressure whenever the

engine is operating and may hold pressure even after the

engine is shut off. Cycle all hydraulic controls including

the auxiliary hydraulic control after the engine is shut

down. Relieve trapped pressure in the lines after the

attachments are shut down and resting on the ground.

During inspection of the hydraulic system:

— Wait for  uid to cool before disconnecting the lines.

Hot hydraulic  uid can cause SEVERE BURNS.

— Do not use your hand to check for leaks. Instead,

use a piece of cardboard or paper to search for leaks.

— Wear appropriate eye protection. Hydraulic  uid can

cause permanent eye injury.

WARNING! Hydraulic  uid under pressure can penetrate

the skin or eyes and cause serious injury, blindness or

death. Fluid leaks under pressure may not be visible.

Use a piece of cardboard or wood to ﬁ nd leaks, not

your hand. Wear a face shield or safety goggles for

eye protection. If  uid is injected into the skin, it must

be removed within a few hours by medical personnel

familiar with this type of injury.

When venting or  lling the hydraulic system, loosen the

 ller cap slowly and remove it gradually.

Never reset any relief valve in the hydraulic system to a

pressure higher than recommended by the manufacturer.

Electrical System Hazards

Before working on the electrical system, disconnect the

battery cable(s).

— Remove the battery negative (-) cable(s)  rst.

— When reconnecting the battery, connect the battery

negative (-) cable(s) last.

The liquid in batteries contains acid, which is a POISON

and can cause SEVERE CHEMICAL BURNS.

Avoid Injury

— Wear a face shield to prevent contact with your eyes.

— Wear chemical-resistant gloves and clothing to keep

electrolyte off your skin and regular clothing.

WARNING! Electrolyte will damage eyes or skin

on contact. Always wear a face shield to avoid

electrolyte in eyes. If electrolyte contacts eyes,  ush

immediately with clean water and get medical attention.

Wear chemical-resistant gloves and protective

clothing to keep electrolyte off skin. If electrolyte

contacts exposed skin or clothing, wash off immediately

with clean water. If electrolyte is ingested, seek

medical attention immediately. NEVER give  uids that

would induce vomiting.

Avoid Explosion

WARNING! Avoid possible serious injury from

explosion. Lead-acid batteries produce extremely

explosive gases especially when being charged. Keep

arcs, sparks, ﬂ ames and lighted tobacco away.

— Do not smoke near batteries.

— Keep arcs, sparks and open  ames away from

batteries.

— Provide adequate ventilation.

Never check the battery by placing a metal object

across the battery posts — the resulting spark could

cause an explosion.

WARNING! Avoid possible serious injury from battery

explosion. Do not charge a battery or boost start the

engine if the battery is frozen. Warm to 60°F (15.5°C)

or the battery may explode and could cause serious

injury.

Safety rules during battery boost starting:

— Follow the instructions for proper “battery boost

starting” as speci ed in the manufacturer’s manual.

— Be sure the machines are not touching.

— Observe the polarity of the batteries and connections.

— Make the  nal cable connection to the engine or the

furthest ground point away from the battery. Never

make the  nal connection at the starter or dead

battery—sparks may ignite the explosive gases

present at the battery.

— When disconnecting cables after jump starting,

remove the cables in reverse order of connection

(e.g.,  nal connection  rst).

Tire And Wheel Maintenance

Check your tires and wheels daily because the stability

of the tractor and mower can be dramatically affected

by tire pressure or damage to tires or wheels.

Check tires for:

— Correct pressure.

— Cuts and bulges.

— Nails or other punctures.

— Uneven or excessive wear.

— Condition of valve stems and caps.

Check wheels for:

— Damage to the rims.

— Missing or loose lug nuts or bolts.

— Misalignment.

All tire service should be performed by a quali ed tire

service center or by an authorized service person who

has been properly trained in the procedures and use of

safety equipment designed for tire servicing.

Perform Maintenance Safely

Tire And Wheel Maintenance (continued)

WARNING! The types of wheels and tires usually

found on this equipment require special care when

servicing to prevent death or serious injury.

Do not in ate the tires above the recommended

pressure. Be sure to replace tire ballast if equipped. See

manufacturer’s speci cations for ballast requirements.

Keep wheel lug nuts tightened to manufacturer’s

recommendations.

A rise in tire pressure during operation is normal, and

should NOT be reduced.

Never rein ate a tire that has been run  at or seriously

underin ated without removing the tire from the wheel.

Have the tire and wheel closely inspected for damage

before remounting.

When adding air to a tire, do so from a distance. Use

a long hose with self-attaching chuck. Always stand

behind tread when adjusting tire pressure.

Do not in ate tires with  ammable gases or from

systems using an alcohol injector.

Never cut or weld on a wheel with an in ated

tire mounted on it. This could cause explosive

decompression.

Check that the tire size and wheel are correctly matched.

When replacing the tires, ensure the tires are of the

appropriate rating speci ed by the manufacturer.

Tires should not be operated at speeds higher than their

rated speed. Most agricultural tires are rated for 20mph

maximum speed.

Avoid

Tire Explosion

Perform Maintenance Safely

Complete Service And Repairs Before Machine

Is Released

Tighten all bolts,  ttings, and connections to torques

speci ed by the manufacturer.

Install all guards, covers, and shields after servicing.

Replace or repair any damaged parts. Re ll and

recharge pressure systems only with manufacturer

approved or recommended  uids.

Start the engine and check for leaks. (See page 23,

Hydraulic System Hazards.) Operate all controls

to make sure the tractor and mower are functioning

properly. Test the machine if necessary. After testing,

shut down and check the work you performed. Are

there any missing cotter pins, washers, locknuts, etc.?

Recheck all  uid levels before releasing the equipment

for operation.

All parts should be inspected during repair and replaced

if worn, cracked or damaged. Excessively worn or

damaged parts can fail and cause injury or death.

Replace any damaged or illegible safety signs.

Mower Blade Maintenance

Do not take chances using damaged or bent blades.

The mower manufacturers from the Association

of Equipment Manufacturers (AEM) and the Farm

Equipment Manufacturers Association (FEMA) advocate

that you DO NOT reuse, straighten, hard face or weld

mower blades. Death or serious injury could result if a

broken blade is thrown from a mower.

Verify

Service Work

When

Completed

Perform Maintenance Safely

Mower Blade Maintenance (continued)

— How are mower blades made?

Mower blades are made of high strength alloy spring

steel. They are hot-forged and shaped to meet the

manufacturer’s individual speci cations, then heat

treated and tempered to a high strength, ductile state

to reduce the possibility of breaking while mowing.

Blades are tested to ensure they meet strength,

hardness, and ductility standards. If a blade fails to

meet any of these speci cations, it will not be used

on the mower.

— What happens when a mower blade bends?

It takes a great amount of impact force to bend

the blade. This impact force often results in the

blades being gouged or chipped. After a blade

is damaged by a gouge or chip a blade failure is

much more likely to occur. When a blade is severely

bent, a microscopic crack may be created in the

blade. Straightening the blade does not remove or

repair this crack, but may cause additional cracks.

Additional stresses during mowing operations can

result in an unexpected blade failure.

— Avoid bending blades. Help prevent mower blades

from bending or cracking by avoiding contact with

solid objects. Mower blades are intended to cut

grass, shrubs, woody vegetation, and small trees and

limbs. They are not intended to contact solid objects

such as rocks, concrete, or steel posts. Inspect the

area prior to mowing. Remove or clearly mark any

solid objects and mow around them.

— Replace damaged blades! Inspect the mower blade(s)

daily or after hitting any solid object. If a mower blade

becomes damaged (bent, gouged, cracked) or worn

more than 25 percent of the original size, it should

be removed and replaced with a new blade. Always

use the original manufacturer’s blades. Aftermarket

brand blades may not meet the mower manufacturer’s

strength, hardness and ductility requirements.

— Do not take chances mowing with damaged or

bent blades. Using a damaged or straightened

mower blade can result in the blade breaking and

being thrown into the operator or a bystander causing

death or serious injury. The price of a new blade is

small compared to the potential for the serious injury

that could result from a bent or broken blade being

thrown from the mower.

Objetos arrojados por la cortadora de césped

Dependiendo del propósito previsto, las cortadoras

están diseñadas para cortar hierba, maleza, broza y

cultivos. Las hojas de la cortadora están diseñadas y

probadas para uso intensivo. Las hojas de la cortadora,

sin embargo, no están diseñadas para entrar en contacto

con objetos sólidos como rocas, cemento o metales. Un

impacto de este tipo puede arrojar objetos rotos hasta

300 pies (92 m) de distancia. Nunca debe haber personas

ajenas a menos de 300 pies (92 m) de una cortadora

giratoria en funcionamiento o a menos de 100 pies (30 m)

de una cortadora de disco correctamente equipada.

Hojas giratorias –

Manténgase

No ponga en

funcionamiento una

cortadora de césped

dañada

Operación con seguridad

Los escudos de la cortadora están diseñados para reducir

el riesgo de objetos arrojados y se deben mantener

correctamente y en su lugar durante las operaciones de

corte.

El riesgo de lesiones graves o muerte puede reducirse

signi cativamente si se siguen estas reglas. Si no se

siguen todas estas reglas de seguridad, la operación

de corte debe detenerse en caso de que alguna

persona ingrese dentro del límite de seguridad

correspondiente a cada tipo de cortadora.

Primero — Inspeccione la zona antes de cortar y retire las

piedras, ramas, alambres, cables, metales, vidrios y otros

objetos sólidos antes de hacer funcionar la máquina. Los

objetos que no puedan retirarse deben marcarse con

claridad y ser evitados con cuidado por el operador.

En áreas sin cultivos con hierba y maleza de altura

su ciente como para ocultar objetos que podrían ser

golpeados por las hojas, inspeccione la zona y retire o

marque los residuos u obstáculos grandes.

Realice el corte de la zona a una altura intermedia.

Inspeccione la zona atentamente y retire o marque

cualquier residuo u obstáculo restante. Corte nuevamente

a la altura  nal deseada.

Segundo — Los escudos para objetos arrojados por la

cortadora deben usarse cuando se opera cerca de caminos,

parques, zonas pobladas u otras zonas donde objetos

arrojados podrían lesionar a personas ajenas o dañar la

propiedad. Siga el manual del operador del fabricante.

Tercero — Cruce en sentido diagonal cuando realiza

el corte a través de zanjas, depresiones marcadas y

hundimientos. Eleve la cortadora para evitar que las hojas

de la cortadora golpeen el suelo.

Siga todas

las reglas de

seguridad

Operación con seguridad

Objetos arrojados por la cortadora de césped

(continuación)

Cortadoras de disco — Cuando se usa una cortadora

de disco, es importante conocer la zona donde se va a

cortar. Si el operador ha realizado cortes en el terreno

antes y está familiarizado con todos los obstáculos

que puede haber, es su ciente observar delante de la

trayectoria de la cortadora para detectar cualquier objeto

adicional que pueda haber ingresado en el terreno. Esté

preparado para detenerse o evitar objetos que podrían

ser peligrosos si son arrojados por la cortadora. Si piensa

cortar en un terreno que no conoce bien y se encuentra

junto a un camino transitado o puede haber personas

a menos de 100 pies (30 m) de la cortadora de césped,

debe inspeccionar y limpiar o marcar el terreno.

Cómo cortar en retroceso

No corte mientras se desplaza en retroceso. Es más

probable que se arrojen objetos y que éstos puedan llegar

más lejos.

Apague la TDF, espere que las hojas dejen de girar, eleve

la cortadora y, después, retroceda.

Corte desplazándose en sentido de avance.

Velocidad de desplazamiento durante el corte

La velocidad de desplazamiento correcta depende de las

condiciones del terreno y del tipo de hierba, la densidad y

la altura que debe cortarse:

— El rango normal de velocidad de desplazamiento es de

2 a 5 mph (3.2 a 8 km/h).

— Use una velocidad de desplazamiento menor para

cortar hierbas altas y densas.

— Use una velocidad de desplazamiento mayor para

cortar hierba delgada a altura media y con condiciones

de terreno sin di cultades.

— Use una velocidad de desplazamiento menor par acortar

en terreno irregular, con pendientes o no muy conocido.

Las cortadoras de disco están diseñadas para usar

velocidades de desplazamiento mayores cuando funcionan

en terrenos despejados de residuos y peligros super ciales.

Use la velocidad

de desplazamiento

correcta

Operación con seguridad

Corte de hierba extremadamente alta

Puede ser necesario cortar dos veces la hierba

extremadamente alta que no sea cultivo. (Consulte la página

13, Objetos arrojados por la cortadora de césped.)

Primera pasada de corte:

— Apague la cortadora y el tractor usando la práctica

correcta de apagado de equipos antes de descender del

tractor. (Consulte la página 18, Prácticas correctas de

apagado de los equipos.)

— Inspeccione la zona y retire o marque cualquier residuo u

obstáculo.

— Corte la hierba a mayor altura (10 a 15 pulg. [25 a 38 cm])

para evitar los objetos ocultos.

Segunda pasada de corte:

— Apague la cortadora y el tractor usando la práctica

correcta de apagado de equipos antes de descender

del tractor.

— Inspeccione la zona y retire o marque cualquier residuo

u obstáculo.

— Corte la hierba a la altura deseada y, de ser posible, a

90 grados con respecto a la primera pasada de corte.

Preste atención a los espacios libres de los

equipos

Las cortadoras con enganche de tres puntos y montaje

lateral tienen un arco de giro mayor que las tipo de tiro.

Deje el espacio libre su ciente para la oscilación de la

cortadora cuando gira.

No permita que haya personas ajenas cerca del tractor

y la cortadora de césped cuando mueve o transporta el

tractor y la cortadora.

Operación con seguridad

Prácticas de seguridad para cortadoras de

césped con laterales y montaje lateral

Las posiciones elevadas de los laterales reducen la

protección de los escudos y aumentan los riesgos de

objetos arrojados y contacto con las hojas.

Evite la posibilidad de lesiones graves o muerte por

objetos arrojados o contacto con las hojas causados

por la elevación y el descenso de los laterales durante

las operaciones de corte:

— No realice cortes con personas ajenas presentes a

menos de 300 pies (92 m) de la cortadora de césped.

— Asegúrese de que no haya personas cerca de la

cortadora mientras se elevan o descienden los

laterales.

— Apague la TDF y espere hasta que todos los elementos

giratorios se hayan detenido antes de elevar la

plataforma o la sección lateral de la cortadora.

— Únicamente eleve el lateral para quitar objetos de la

trayectoria de corte o para acompañar una pendiente

del terreno.

— Descienda hasta el suelo el lateral elevado una vez que

se eliminó el objeto o se superó la pendiente.

— Detenga el trabajo de corte si alguna persona se acerca

a menos de 300 pies (92 m) de la zona de corte.

Prácticas de seguridad para trabajos de corte en

orillas de zanjas

Use extremo cuidado al realizar cortes en orillas

de zanjas. Preste atención a escurrimientos, zonas

erosionadas y obstrucciones para el corte a lo largo de

las orillas de zanjas. Si se golpean obstrucciones con

cortadoras de montaje lateral o con aguilón, el extremo

delantero del tractor puede desviarse hacia la zanja.

Operación con seguridad

Los trabajos en orillas de zanjas con aguilón y lateral

elevado pueden reducir la e cacia de la protección del

operador de la cortadora que proporcionan los escudos

para objetos arrojados.

— Cuando realice estas operaciones, use cabinas cerradas

con ROPS, cerramientos protectores especiales y otros

escudos para el operador que ofrece el fabricante.

— Inspeccione la zona de corte y retire o marque todos

los objetos extraños y los residuos que deberá esquivar

la cortadora.

Prácticas de seguridad para trabajos de corte en

terrenos desparejos

Las pendientes y los terrenos desparejos reducen la

estabilidad del tractor y de la cortadora.

Como en todas las condiciones de corte, use tractores

equipados con ROPS y cinturón de seguridad. Asegúrese

de que el ROPS está elevado y trabado en su lugar y

use siempre el cinturón de seguridad.

Prevenga los vuelcos del tractor y de la cortadora de césped

y mantenga controlada la estabilidad de los equipos:

— Repase los manuales del operador del tractor y de la

cortadora para ver las prácticas de seguridad para

operaciones en pendientes y terrenos desparejos.

Explique las prácticas a los operadores que no puedan

leerlas.

— Evite trabajar en pendientes extremadamente

empinadas.

Realización de mantenimiento con seguridad

Mantenimiento de neumáticos y ruedas

(continuación)

¡ADVERTENCIA! Los tipos de ruedas y neumáticos

que generalmente se encuentran en estos equipos

requieren cuidados especiales al realizar servicios

para evitar lesiones graves o la muerte.

No in e los neumáticos por encima de la presión

recomendada. Asegúrese de volver a colocar el lastre

de los neumáticos si está instalado. Consulte las

especi caciones del fabricante para ver los requisitos

de lastre.

Mantenga las tuercas de las ruedas apretadas según las

recomendaciones del fabricante.

Es normal que la presión de los neumáticos aumente

durante el funcionamiento; NO se debe reducir.

Nunca vuelva a in ar un neumático que se ha desin ado

mucho o por completo sin retirar el neumático de la

rueda. Haga inspeccionar atentamente el neumático y la

rueda para detectar daños antes de volverlos a armar.

Al agregar aire a un neumático, hágalo desde cierta

distancia. Use una manguera larga con mandril de

auto jación. Siempre párese detrás de la trocha cuando

ajusta la presión de un neumático.

No in e neumáticos con gases in amables o con sistemas

que usan un inyector de alcohol.

Nunca corte o suelde una rueda con un neumático in ado

instalado en ella. Esto podría causar descompresión

explosiva.

Veri que que el tamaño del neumático y la rueda

coincidan correctamente.

Cuando reemplaza neumáticos, asegúrese de que sean de

la clasi cación adecuada especi cada por el fabricante.

Los neumáticos no deben funcionar a velocidades más

altas que las nominales. La mayoría de los neumáticos

para agricultura están clasi cados para una velocidad

máxima de 20 mph (32 km/h).

Evite la explosión

de los neumáticos

Realización de mantenimiento con seguridad

Servicio y reparaciones completas antes de

liberar la máquina

Apriete todos los pernos, accesorios y conexiones con las

torsiones especi cadas por el fabricante.

Instale todas las guardas, cubiertas y escudos después

de realizar los servicios. Reemplace o repare los que

estén dañados. Llene y recargue los sistemas a presión

sólo con los  uidos aprobados o recomendados por el

fabricante.

Arranque el motor y revise para detectar fugas. (Consulte

la página 23, Riesgos del sistema hidráulico.) Haga

funcionar todos los controles para asegurarse de que el

tractor y la cortadora de césped funcionan correctamente.

Pruebe la máquina si es necesario. Después de las

pruebas, apague y veri que el trabajo realizado. ¿Falta

algún pasador, arandela, tuerca de seguridad, etc.?

Vuelva a revisar todos los niveles de  uidos antes de

liberar la máquina para el funcionamiento.

Todas las piezas deben ser inspeccionadas durante la

reparación y deben reemplazarse si están gastadas,

rajadas o dañadas. Las piezas excesivamente gastadas o

dañadas pueden fallar y causar lesiones o la muerte.

Reemplace cualquier letrero dañado o ilegible.

Mantenimiento de las hojas de la cortadora

No corra riesgos usando hojas dañadas o dobladas. Los

fabricantes de cortadoras de césped de la Asociación

de Fabricantes de Equipos (Association of Equipment

Manufacturers, AEM) y la Asociación de Fabricantes de

Equipos para Agricultura (Farm Equipment Manufacturers

Association, FEMA) piden que las hojas de cortadoras

NO se reutilicen, enderecen, refuercen en su super cie o

suelden. Si una hoja rota es arrojada por una cortadora,

podrían producirse lesiones graves o la muerte.

Veriﬁ que el trabajo

de servicio cuando

está completo

Realización de mantenimiento con seguridad

Mantenimiento de las hojas de la cortadora

(continuación)

— ¿Cómo están hechas las hojas de la cortadora

de césped? Están hechas acero para resortes de

aleación de alta resistencia. Se forjan en caliente y se

les da forma para cumplir con las especi caciones

individuales del fabricante; luego, se tratan y templan

a un estado dúctil, de alta resistencia para reducir la

posibilidad de rupturas durante el corte. Las hojas se

prueban para garantizar que cumplan con las normas

de resistencia, dureza y ductilidad. Si una hoja no

cumple con alguna de estas especi caciones, no se

utilizará en la cortadora de césped.

— ¿Qué sucede cuando se dobla una hoja de la

cortadora? Se necesita una gran fuerza de impacto

para doblar la hoja. Esta fuerza de impacto a menudo

resulta en que las hojas se agujerean o marcan. Una

vez que una hoja está dañada por un agujero o una

marca, es mucho más probable que ocurra una falla

de la hoja. Cuando una hoja está gravemente doblada,

puede crearse una rajadura microscópica en ella.

Enderezar la hoja no quita o repara esta rajadura, sino

que puede causar rajaduras adicionales.Tensiones

adicionales durante los trabajos de corte pueden

resultar en una falla imprevista de la hoja.

— Evite doblar las hojas. Contribuya a prevenir que las

hojas de la cortadora se doblen o rajen evitando el

contacto con objetos sólidos. Las hojas de la cortadora

de césped están destinadas a cortar hierba, arbustos,

vegetación leñosa y árboles y ramas pequeños. No

están diseñadas para entrar en contacto con objetos

sólidos como roca, cemento o postes de acero.

Inspeccione la zona antes de usar la cortadora. Retire

o marque claramente los objetos sólidos y corte

alrededor de ellos.

— Sustituya las hojas dañadas! Inspeccione las hojas

de la cortadora diariamente o después de golpear

algún objeto sólido. Si una hoja de la cortadora de

césped se daña (está doblada, agujereada, rajada) o

desgasta más del 25 por ciento del tamaño original,

debe retirarse y sustituirse con una nueva. Siempre use

las hojas originales del fabricante. Las hojas de marcas

no originales pueden no cumplir con los requisitos de

resistencia, dureza y ductilidad del fabricante de la

cortadora.

— No corra riesgos usando hojas dañadas o dobladas.

El uso de una hoja de cortadora dañada o enderezada

puede resultar en la ruptura de la hoja y que la hoja

sea arrojada hacia el operador o una persona ajena

causando una lesión grave o la muerte. El precio

de una nueva hoja es bajo en comparación con la

posibilidad de una lesión grave que podría resultar de

una hoja doblada o rota arrojada por la cortadora

INTRODUCTION

We are pleased to have you as a Rhino customer. Your Rotary Cutter has been carefully designed with care

and built with quality materials by skilled workers to give maximum service with minimum down time. This

manual is provided to give you the necessary operating and maintenance instructions for keeping your rotary

cutter in top operating condition. Careful use and timely service saves extensive repairs and costly downtime

losses. Please read this manual thoroughly. Understand what each control is for and how to use it.

Rhino typically offers three types of shielding to protect the operator, passerby, livestock, and property from

thrown objects... deflectors, single chain guards, and double chainguards. Shielding should be selected based

on the intended use of the mower. Double chainguards or deflectors should be used for highway, right-of-way,

parks or greenbelt mowing or all other mowing where human dwellings, vehicles, or livestock could be within

300 feet of the mower. Chainguards are more durable, provide a longer service life and require less

maintenance and replacement than deflectors. Single chainguards may be sufficient for agriculture and other

mower use only where passersby or property are not within 300 feet of the mower during operation.

No shielding is 100% effective in preventing thrown objects. The possibility of injury and property damage from

this hazard can be substantially reduce by selecting proper shielding, maintaining the mower and shielding in

good operational condition, inspecting the area for foreign debris before mowing, operating the mower at a

minimum cutting height of 4", and keep unprotected persons at a minimum distance of 300 feet from the

mower at all times during operation.

Safety is of primary importance to the owner/operator and to the manufacturer. Observe all safety precautions

decaled on the machine and noted throughout the manual for safe operation of implement. If any assistance or

additional information is needed, contact your authorized Rhino dealer. The owner/operator/dealer should

know and understand the Safety Messages before assembly and be aware of the hazards of operating this

cutter during assembly, use, and maintenance. The Safety Alert Symbol combined with a Signal Word, as seen

below, is intended to warn the owner/operator of impending hazards and the degree of possible injury faced

when operating this machine.

Indicates an imminently hazardous situation that, if not avoided, WILL result in DEATH OR

VERY SERIOUS INJURY.

Indicates an imminently hazardous situation that, if not avoided, COULD result in DEATH

OR SERIOUS INJURY.

Indicates an imminently hazardous situation that, if not avoided, MAY result in MINOR

INJURY.

Identifies special instructions or procedures that, if not strictly observed, could result in

KEY OPERATION POINTS

• Cutting performance and distribution are best when cutter is level from side to side and front to rear.

• In extra heavy material, rear chains will allow better discharge and better distribution than solid rear bands.

• Never operate the Mower below full PTO speed of 540 or 1000 rpm.

• Corn should be cut at 5 to 6 mph. If full PTO rpm cannot be maintained, use one lower gear.

Operating Noise Level/Sound Pressure

The sound levels at the operator's ear from the attached machine (rotary cutter) are at least 10 dB(A) below the

levels from typical Agricultural tractors used to power and transport this machine. Therefore, the Noise

emission values given by the OEM of the Agricultural tractor used to power and transport this machine would

be valid when this machine is attached to and operated by that Agricultural tractor in all OEM recommended

applications.

ASSEMBLY

TW144 01/11 Assembly Section 3-6

ASSEMBLY

CUTTER LEVELING

Often when the unit is first assembled and placed on a horizontal surface, the cutter is not level front to rear or

side to side. Proper leveling must be obtained in order to prevent skid shoes from plowing in the dirt and to

obtain a clean, level cutting performance.

Leveling must first be conducted left to right with measurements being taken at the front corner of the mower

deck from the ground to the bottom of the skid shoe. If the two dimensions measured are not equal, the cutter

must be leveled left to right. This may be done by the following procedure:

Using the axle arm assembly on the high side of the cutter deck, loosen the bottom two clamp bolts one or two

turns and tighten the top two clamp bolts. This should be done in an alternating sequence, measuring the

height of the skid shoes after each adjustment. Continue with this process until no additional leveling from side

to side can be obtained. If the unit is still not level, work must then be done on the axle arm assembly which is

on the low side of the cutter.

This cannot be done until the weight of the cutter is removed from the axle arm by placing a jackstand

underneath the cutter and putting the hydraulic valve in the float position (or loosening the ratchet hack if the

hydraulic cylinder is not used), which will then release pressure on the cylinder and the load on the axle arm.

Once this has been done, the axle arm may be adjusted by first loosening the top two bolts one or two turns

and then tightening the bottom two bolts. After each adjustment, the cutter should be lifted off of the jackstand

using the hydraulic cylinder or ratchet jack and then placed back on the jackstand if further adjustment is

needed. This process should be continued until the cutter becomes level left to right.

Once leveling from side to side has been completed, leveling from front to rear should be done. To level the

cutter from front to rear, the leveling rod which links the tongue and the rear axle must be adjusted. To lower

the front, lengthen the level rods and to raise the front, shorten the level rods. IMPORTANT: Adjust level rods

the same length to maintain equal tension in rods. Improper adjustment may cause rods to snap or bend.

Once machine has been leveled according to directions, the cutting height can be set.

even death could result from falling off the tractor--particularly during a turnover

when the operator could be pinned under the ROPS.

(SG-7)

OPERATION

TW144 01/11 Operation Section 4-5

OPERATION

2.3 Tractor Horsepower

The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing

conditions, the TW144 lift mower requires a tractor with at least 70 HP and the semi-mount and pull type

mower require at least 55 HP. Operating the mower with a tractor that does not have adequate power may

damage the tractor engine. Exceeding 95 HP may cause mower damage by overpowering the unit in heavy

cutting conditions.

2.4 3-Point Hitch

Lift Type Mower-The tractor 3-point hitch must be

rated to lift at least 2142 lbs.

The Model TW144 is designed to be mounted on a

tractor with CATII or CATIII 3-point or CATII or

CATIII Quick Hitch.

Refer to the tractor operator’s manual for the

category of the tractor being used. If the hitch does

not conform to ASABE dimensions, the mower may

not fit or raise properly. Consult an authorized

dealer for possible modification procedures to

mount non-conforming hitches.

Depending on the hitch category, certain size pins

are used to attach the mower to the tractor. Quick

Hitch requires 1-7/16 diameter lower pin and 1-1/4

diameter upper pin. CATII hitches require 1-1/8

lower pins and 1 inch upper pins. CATIII hitches

require 1-7/16 lower pins and 1-1/4 upper pin

diameters.

Our 3-point Quick Hitch is designed to connect to a

Quick-Attach coupler making mounting and dis-

mounting your mower easier. The 3-Point Quick

Hitch is also designed to connect the mower to a

tractor’s 3-point linkage without the use of a Quick-

Attach Coupler.

2.2 Tractor Safety Devices

If transporting or operating the tractor and implement near a public roadway, the tractor must be equipped with

proper warning lighting and a Slow Moving Vehicle (SMV) emblem which are clearly visible from the rear of

the unit. Lights and a SMV emblem must be equipped directly on implements if the visibility of the tractor

warning signals are obscured.

Maintain all manufacturer equipped safety shields and guards. Always replace shields and guards that were

removed for access to connect, service, or repair the tractor or implement. Never operate the tractor PTO

with the PTO master shield missing or in the raised position. OPS-U- 0004

OPERATION

TW144 01/11 Operation Section 4-6

OPERATION

2.5 Drawbar-Pull Type Mower

For pull type mowers (540 and 1000 RPM) equipped

with an equal-angle driveline, the tractor drawbar must

be positioned at a 14” distance from the hitch point to

the PTO shaft end for proper operation and minimal

wear to the driveline and tractor.

If attaching the mower tongue clevis to a 3-point hitch drawbar supported by the lower lift arms, the attaching

point must be extended past the main bar to allow for turning without binding the clevis and bar. Lift arm

stabilizers must be used with this type of drawbar to prevent the mower from swaying from side to side. OPS-

R- 0061_C.

2.6 Front End Weight

A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end

weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the

front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front

weights and weight carriers can be purchased through an authorized tractor dealership. OPS-U- 0005

OPERATION

TW144 01/11 Operation Section 4-7

OPERATION

Do not connect the PTO driveline to the tractor or operate the implement unless the

implement is securely connected to the tractor.

2.7 Power Take Off (PTO)

Depending on the unit, the mower is designed to operate at a PTO speed of 540 or 1000 RPM. Most tractors

operate at either 540, or a combination of 540 and 1000 RPM PTO speeds. The operating speed of the

mower and tractor can be determined by the number of splines on the driveline yoke and PTO output shaft.

Those operating at 540 RPM will have a 6-spline shaft and those operating at 1000 RPM will have a 21-spline

shaft or a 1-3/4” 20 spline shaft. Refer to the tractor owner’s manual for instructions to change PTO speeds on

models that operate at more than one speed.

If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an

over-running clutch must be used between the PTO output shaft and the driveline of the mower. An

authorized tractor dealer can provide the over-running clutch and its installation if needed. OPS-U- 0006

DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor

PTO. Use of an adapter can double the operating speed of the Implement resulting in

excessive vibration, thrown objects, and blade and implement failure. Adapter use will also

change the working length of the driveline exposing unshielded driveline areas. Serious

bodily injury and/or equipment failure can result from using a PTO adapter. Consult an

authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.

(S3PT-14)

Never operate the Tractor and Mower if the Implement input driveline is directly connected

to the Tractor transmission. Tractor braking distances can be substantially increased by

the momentum of the rotating Mower blades driving the Tractor transmission even though

the Tractor clutch has been disengaged. Install an over running clutch between the Tractor

PTO and the Mower driveline to prevent this potentially dangerous situation.

(S3PT-16)

2.8 Tire Spacing

Tractor tires should be set a minimum of 60”(1.5

mm) apart measured from inside of tire to inside of

tire. Refer to the tractor Operator’s Manual or

consult an authorized dealer for instructions to

change tractor tire spacing. OPS-R- 0062

TW144 01/11 Operation Section 4-8

OPERATION

3. GETTING ON AND OFF THE TRACTOR

Before getting onto the tractor, the operator must read and completely understand the implement and tractor

operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for

a complete explanation. OPS-U- 0007

Do not mount or dismount the Tractor while the tractor is moving. Mount

the Tractor only when the Tractor and all moving parts are

completelystopped.

(SG-12)

3.1 Boarding the Tractor

Use both hands and equipped handrails and steps for support when boarding the tractor. Never use control

levers for support when mounting the tractor. Seat yourself in the operator’s seat and secure the seat belt

around you.

Never allow passengers to ride on the tractor or attached equipment. Riders can easily fall off and be

seriously injured or killed from falling off and being ran over. It is the operator’s responsibility to forbid all extra

riders at all times. OPS-U- 0008

Never allow children to operate, ride on, or come close to the Tractor or

Implement. Usually, 16-17 year-old children who are mature and

responsible can operate the implement with adult supervision, if they

have read and understand the Operator’s Manuals, been trained in

proper operation of the tractor and Implement, and are physically large

enough to reach and operate the controls easily.

(SG-11)

Never allow children or other persons to ride on the Tractor or Implement.

Falling off can result in serious injury or death.

(SG-10)

3.2 Dismounting the Tractor

Before dismounting, park the tractor and implement on a reasonably level surface, apply the parking brake,

idle the engine down, disengage the PTO, and lower the implement to the ground. Shut down the tractor

engine according to the operator’s manual, remove the key, and wait for all motion to completely stop. Never

leave the seat until the tractor, its engine and all moving parts have come to a complete stop.

Use hand rails and steps when exiting the tractor. Be careful of your step and use extra caution when mud,

ice, snow or other matter has accumulated on the steps or hand rails. Use all handrails and steps for support

and never rush or jump off the tractor. OPS-U- 0009

OPERATION

TW144 01/11 Operation Section 4-9

OPERATION

BEFORE leaving the tractor seat lower the implement, set the parking

brake and/or set the tractor transmission in parking gear, disengage the

PTO, stop the engine, remove the key, and wait for all moving parts to

stop. Place the tractor shift lever into a low range or parking gear to

prevent the tractor from rolling. Never dismount a Tractor that is moving

or while the engine is running. Operate the Tractor controls from the

tractor seat only.

(SG-9)

4. STARTING THE TRACTOR

The operator must have a complete understanding of the placement, function, and operational use of all

tractor controls before starting the tractor. Review the tractor operator’s manual and consult an authorized

dealer for tractor operation instructions if needed.

Essential Tractor Controls:

• Locate the light control switch.

• Locate the engine shut off control.

• Locate the brake pedals and the clutch.

• Locate the PTO control.

• Locate the 3-point hitch control lever.

• Locate the hydraulic remote control levers.

Before starting the tractor ensure the following:

• Conduct all pre-start operation inspection and service according to the tractor operator’s manual.

• Make sure all guards, shields, and other safety devices are securely in place.

• The parking brake is on.

• The PTO control lever is disengaged.

• The 3-point hitch control lever is in the lowered position.

• The hydraulic remote control levers are in the neutral position.

• The tractor transmission levers are in park or neutral.

Refer to the tractor owner’s manual for tractor starting procedures. Only start the tractor while seated and

belted in the tractor operator’s seat. Never bypass the ignition switch by short circuiting the starter solenoid.

After the tractor engine is running, avoid accidental contact with the tractor transmission to prevent sudden

and unexpected tractor movement. OPS-U-0028

Never run the Tractor engine in a closed building or without adequate ventilation. The

exhaust fumes can be hazardous to your health.

(SG-23)

Start tractor only when properly seated in the Tractor seat. Starting a

tractor in gear can result in injury or death. Read the Tractor operators

manual for proper starting instructions.

5.2 3-Point Quick Hitch

Our 3-Point Quick Hitch is designed to connect to a

Quick-Attach Coupler making mounting and

dismounting your mower easier. The 3-Point Quick

Hitch is also designed to connect the cutter to a

tractor’s three-point linkage without the use of a

Quick-Attach Coupler.

5.3 Connecting Mower - Lift Type (Quick Hitch)

Crushing Hazard between Quick-Hitch and Implement. Do not allow anyone to stand

between the Quick-Hitch and implement during hook-up operations. Never operate the

hydraulic 3-point lift controls while someone is directly behind the tractor.

1. Make certain the implement’s upper and lower

hitch pins are secured.

2. Lower the tractor’s 3-point lift until the three

Quick-Hitch hooks are lower than the

implements hitch pins. Carefully back the

tractor to align the Quick-Hitch hooks under the

implement’s hitch pins.

3. Slowly raise the tractor’s 3-point lift until the

lower Quick-hitch hooks lock into place over

the implement’s 3-point hitch pins.

IMPORTANT: Make certain the implement’s top 3-

point hitch pin is captured by the Quick-Hitch top 3-

point hook. If not consult your Quick Hitch manual

for required adjustment.

IMPORTANT: The Quick Hitch will move mower

further from tractor which will require checking the

following:

1. Driveline length

2. Tractor stability

NOTE: Offset Adapter Hitches are available to

position the mower to the left or right. Mowers with

Offset Adapter Hitches connect to the 3-point hitch

the same way as the mower A-frame. See Offset

Adapter Hitch in the Assembly Section for details to

equip the mower with this feature.

OPERATION

TW144 01/11 Operation Section 4-12

OPERATION

5.5 Connecting the Mower-Pull Type

1. Make sure the tractor is equipped with the

correct PTO shaft and the drawbar is extended

14” from the end of the PTO shaft to the hitch

point.

2. Block the mower wheels in place and use the

attached parking jack to raise or lower the

tongue clevis to the height of the tractor

drawbar. The parking jack can be rotated 15

degrees in each direction to obtain a near

vertical position. Note: Always place jack foot

on firm surface or place board under jack for

support.

3. Board the tractor and start the engine. Back the

tractor to the mower aligning the drawbar hitch

hole with the mower hitch clevis. Turn off the

tractor engine, set the parking brake, place the

tractor in park, and dismount.

4. To attach the mower, place two 1” flatwashers

(1) positioned under top lip of tongue clevis and

to the top of drawbar. Add additional 1”

flatwashers (2) between the bottom of drawbar

and bottom lip of clevis to fill open space. Insert

a 3/4” x 4-1/2” grade 5 or 8 bolt (3) through

clevis and drawbar and retain in position with a

1” locknut (4). The bolt and locknut should be

tightened securely to support the tongue

properly without springing or breaking the

clevis. Never attach mower to the tractor with a

pin not having a nut..

5. Securely attach mower safety chain to tractor

drawbar or drawbar support frame.

6. Lower the jack until the tongue is completely

supported by the drawbar. Remove jack from

the tongue and place on storage bracket of

mower main frame.

5.4 Safety Tow Chain

If the mower is towed on a public roadway, a safety chain with tensile strength equal to or greater than the

gross weight of the mower must be connected between the tractor and mower. This will help control the

implement in the event the tongue becomes disconnected from the drawbar. Make sure the chain is attached

to a secure location on the tractor and not to an intermediate support.

After connecting both ends of the safety chain, drive the tractor to the right and left to check for proper chain

length. Adjust length as necessary and allow only enough slack in the chain to make a maximum turn in both

directions. When not in use, store the safety chain to protect it from mud or standing water by wrapping the

chain around the tongue. Replace the safety chain if one or more links or end fittings are broken, stretched or

otherwise damaged or deformed. OPS-U-0039

OPERATION

TW144 01/11 Operation Section 4-13

OPERATION

7. If using a hydraulic cylinder, connect hydraulic hose ends into tractor hydraulic ports.

8. If the mower has been attached to a 3-point hitch drawbar, adjust any tractor equipped lower link check

chains, guide blocks, or sway blocks to prevent the hitch and mower from swaying side to side. Note:

Never raise the 3-point lift with the mower attached as catastrophic driveline damage will occr.

6.1 Setting Mower Height- Lift Type

1. Park the tractor and mower on level ground.

2. Using the 3-point hitch control lever, position

the front of the mower with its side skids 1” less

off the ground than desired cut height. For

example, for a 3” cut, position the skids 2” from

the ground. Set the 3-point control lever stop at

this position to maintain this height when

raising and lowering the mower.

3. Shut down the tractor and remove the key.

4. Level the mower deck front to rear by extending

or retracting the 3-point top link.

6. SETTING THE MOWER

Properly setting the cutting height is essential for efficient and safe operation. A properly set mower will make

a more uniform cut, distribute clippings more evenly, require minimal tractor work, and follow the contour of

uneven terrain. NOTE: Avoid very low cutting heights, striking the ground with the blades gives the most

damaging shock loads and will cause damage to the mower and drive. Blades contacting the ground may

cause objects to be thrown out from under the mower deck. Always avoid operating the mower at a height

which causes the blades to contact the ground. OPS-U- 0010

Never work under the Implement, the framework, or any lifted

component unless the Implement is securely supported or blocked up

to prevent sudden or inadvertent falling which could cause serious

injury or even death.

(SG-14)

OPERATION

TW144 01/11 Operation Section 4-14

OPERATION

5. Level the mower side to side by manipulating

one lower lift arm length. On most tractors, at

least one of the lift arms is designed to allow for

manipulation of its length. Shortening or

extending will allow for deck leveling from side

to side. .

6. Securely block up the mower at this height.

7. Remove the bolts securing the tailwheel beam

support brackets and allow the tailwheel(s) to

rest at ground level. Align beam and

positioning bracket holes with closest set of

holes in support brackets and reinstall securing

the beam(s) in position. Tighten all bolts and

nuts.

8. Extend the tractor’s top 3-point link so that

when lifting the mower, the front of the deck will

raise 2 to 2½" before the tail wheel(s) leaves

the ground. This will allow the mower to follow

the contour of uneven terrain.

Note: Install optional check chains when there is a

problem with the hydraulic 3-Point lift maintaining a

set height or when a constant preadjusted cut

height is required. See check chains in the

Assembly Section for equipping the tractor and

mower with this accessory.

6.2 Setting Mowing Height-Pull Type

1. Park the tractor and mower on level ground.

2. Using the tailwheel rachet jack or hydraulic

cylinder, position the mower so the skid

shoes are 1” less off the ground than the

desired final cut height. For example, if a 3”

cut is desired, raise or lower the mower until

the skid shoes are 2” off the ground. If a

hydraulic cylinder is used, stroke control

spacers can be placed on the hydraulic shaft

to maintain a set cutting height each time the

mower is raised and lowered..

3. Adjust the mower leveling rod so that the

front of the mower is approximately 3/4” lower

that the rear.

OPERATION

TW144 01/11 Operation Section 4-15

OPERATION

4. If the mower is attached to a 3-point hitch

drawbar, adjust any tractor equipped lower

link check chains, guide blocks, or sway

blocks to prevent the hitch and mower from

swaying from side to side. Never raise the 3-

point lift with the mower attached as

catastrophic driveline damage will occur.

6.3 Setting Deck Pitch

Lower Horse Power - Better Fuel Efficiency

To increase fuel efficiency and lower horsepower

requirements for mower operation, the mower

should be operated with the deck approximately 3/

4" LOWER IN THE FRONT THAN THE REAR.

Operating the mower at this pitch will allow the

mower to cut the grass only once and requires less

work from the tractor.

Increase Mulching

To increase mulching of the grass or crop material

during mower operation, the mower should be

operated with the deck approximately 3/4" HIGHER

IN THE FRONT THAN THE REAR.

Operating the mower at this pitch will allow the

mower to cut the grass twice and can result in a

more even cut and improved distribution of the cut

material.

IMPORTANT:

Adjust the leveling rods the same amount and

maintain equal tension in the rods. Improper

adjustment may cause rods to snap or bend.

Retighten the jamnuts after the deck pitch has been

set. OPS-U-0041

OPERATION

TW144 01/11 Operation Section 4-16

OPERATION

7.1 Driveline Length Check

When fitting the mower to the tractor, the telescoping driveline must be inspected to ensure that at its most

compressed position, the profiles do not “bottom out”, and when at its farthest extended position, there is

sufficient engagement between the profiles to operate safely. At its shortest length, there must be at least a 1”

clearance between each profile end and opposite profile universal joint. At its farthest operating extension, a

minimum profile engagement of 12” must be maintained.

7. DRIVELINE ATTACHMENT

The driveline yoke and tractor PTO shaft must be

dirt free and greased for attachment.

To connect the mower driveline to the tractor PTO

output shaft, pull the driveline yoke collar back and

align the grooves and splines of the yoke with those

of the PTO shaft. Push the driveline yoke onto the

PTO shaft, release the locking collar, and position

the yoke until the locking collar balls are seated

onto the PTO shaft. Push and pull the driveline

back and forth several times to ensure a secure

attachment. OPS-R-0003_A

When attaching the Implement input driveline to the Tractor PTO, it is important that the

connecting yoke spring activated locking collar slides freely and the locking balls are seated

securely in the groove on the Tractor PTO shaft. Push and pull the driveline back and forth

several times to ensure it is securely attached. A driveline not attached correctly to the

Tractor PTO shaft could come loose and result in personal injury and damage to the

Implement.

(S3PT-17)

Before operating the Implement, check to make sure the Implement input driveline will not

bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates

the outer housing until the assembly becomes solid-it can shorten no more. Bottoming out

can cause serious damage to the Tractor PTO by pushing the PTO into the Tractor and

through the support bearings or downward onto the PTO shaft, breaking it off. A broken

driveline can cause personal injury.

(S3PT-18)

OPERATION

TW144 01/11 Operation Section 4-17

OPERATION

“Bottoming Out” Check Procedure

• Disconnect driveline from the tractor and slide

the profiles together until fully compressed.

• Place a mark on the inner shield 1/8” from the

end of the outer shield.

• Reattach the driveline to the PTO Shaft.

• Lift and Semi-Mount Type - Raise the mower/

Pull Type - Turn sharply and watch the

driveline as it approaches the mark. If the

distance between the mark and the end of the

outer shield tube becomes less than 2” at any

point, the driveline must be shortened. OPS-

R-0004_D

Shorten the driveline profiles as follows:

• Remove the driveline from the tractor.

• Position the mower (Lift and Semi-Mount Type -

Raise and lower/ Pull Type - Turn sharply) to

the point with the shortest distance between

the tractor PTO shaft and cutter gearbox. Shut

down the tractor and securely block the mower

in this position.

• Pull driveline apart and reattach yoke to PTO

shaft.

• Hold driveline sections parallel to one another

and measure back 1” from yoke of each shaft

and place mark on opposite section. Cut this

length off with a saw.

• Round off all sharp edges and debur.

• Thoroughly grease then reinstall the driveline.

• Recheck for proper operation.

Engagement Check Procedure

• With the driveline attached, position the mower to the point where the telescoping driveline is at its

maximum extension. Completely shut down the tractor and secure in position.

• Mark the inner driveline shield 1/8” from the end of the outer shield.

• Disconnect the driveline from the tractor and separate the two driveline halves.

• Measure the distance from the mark to the end of the inner profile. This length is the amount the driveline

profiles were engaged.

• If the engaged length is less than 12” for a CV driveline and less than 6” for a non-CV driveline, the shaft is

considered too short and should be replaced with a longer shaft. Consult an authorized dealer to

purchase the required driveline length.

NOTE: When raising the mower, at least 1” clearance must be maintained between the driveline and the

mower deck. If necessary, place an upper lift stop on the 3-point hitch control lever to limit the height the

mower can be raised. OPS-R-0005-G

OPERATION

TW144 01/11 Operation Section 4-18

OPERATION

7.2 Constant Velocity (CV) Driveline

Mowers are equipped with a Constant Velocity (CV) driveline, the maximum turning angle between the tractor

and mower must be determined to ensure the joint angle does not over-extend which can cause CV joint

damage. Constant Velocity joints enable the driveline to operate smoothly with no vibrations and clattering at

angles up to 80°. Angles greater than 80° will result in mechanical damage to the CV joint and mower

driveline.

The Constant Velocity joint must be lubricated every 20-40 hours of operation as specified in the Maintenance

Section. Failure to properly lubricate the joint will result in accelerated wear and joint component failure.

CV Driveline Maximum Angle Check Procedure

•With the mower attached to the tractor and the driveline disconnected from the tractor PTO stub make

a hard left turn until there is approximately a 1" clearance between the left rear tractor tire and mower

frame or tongue.

• Stop and completely shut down the tractor. Place the tractor in Park and apply the Parking Brake before

dismounting.

• Check the CV joint at this maximum turning radius by holding the driveline yoke above the PTO shaft and

then angle the CV joint to its maximum angle. A minimum difference of 10 degrees between the center

line of the yoke and the PTO shaft must be maintained to ensure the joint will not be over angled. If the

joint cannot be angled at least 10°, there is a potential problem of over-angling the joint while making

sharp turns.

• Solutions: To ensure the joint is not damaged, check the following:

Check the drawbar length to ensure that it is at the proper length for the RPM speed of the mower.

Move the tractor rear tires wider apart to limit the tractor turning radius.

Position the mower at multiple angles and perform the above procedure. Determine the sharpest turning

radius that maintains a safe operating angle and note this position to the operator. OPS-R-0006_A

OPERATION

TW144 01/11 Operation Section 4-19

OPERATION

8. PRE-OPERATION INSPECTION AND SERVICE

Before each use, a pre-operation inspection and service of the implement and tractor must be performed.

This includes routine maintenance and scheduled lubrication, inspecting that all safety devices are equipped

and functional, and performing needed repairs. DO NOT operate the unit if the pre-operation inspection

reveals any condition affecting safe operation. Perform repairs and replacement of damaged and missing

parts as soon as noticed. By performing a thorough pre-operation inspection and service, valuable down time

and repair cost can be avoided. OPS-U-0029

Always disconnect the main PTO Driveline from the Tractor before performing service on

the Implement. Never work on the Implement with the tractor PTO driveline connected and

TW144 01/11 Operation Section 4-25

OPERATION

Operating the mower with loose blade hardware will damage the blade holder or blades and

can result in blade breakage or blade fastener failure. Broken blades or bolts can be thrown

out from under the mower for distances up to 300 feet. When the blades are replaced, the

fastening hardware must be replaced. Check and retighten the blade hardware after the first

eight hours of operation. In severe cutting conditions, recheck the blade carrier and blade

bolt torque every 50 hours.

To help prevent structural damage caused by loose hardware, tighten gearbox mounting

hardware as specified. Check the fastener torque after first 8 hours of use and every 50

hours thereafter.

Inspect the Blades daily for abnormal wear. REPLACE BOTH BLADES on that carrier

IMMEDIATELY if either blade has:

• Become bent or deformed from it’s original shape or

• Any cracks are visible, or

9. DRIVING THE TRACTOR AND IMPLEMENT

Safe tractor transport requires the operator possess a thorough knowledge of the model being operated and

precautions to take while driving with an attached implement. Ensure the tractor has the capacity to handle the

weight of the implement and the tractor operating controls are set for safe transport. To ensure safety while

driving the tractor with an attached implement, review the following. OPS-U- 0012

Never run the Tractor engine in a closed building or without adequate ventilation. The

exhaust fumes can be hazardous to your health.

(SG-23)

Transport only at speeds where you can maintain control of the

equipment. Serious accidents and injuries can result from operating this

equipment at high speeds. Understand the Tractor and Implement and

how it handles before transporting on streets and highways. Make sure the Tractor steering

and brakes are in good condition and operate properly.

Before transporting the Tractor and Implement, determine the proper transport speeds for

you and the equipment. Make sure you abide by the following rules:

Test the tractor at a slow speed and increase the speed slowly. Apply the Brakes smoothly

to determine the stopping characteristics of the Tractor and Implement. As you increase

the speed of the Tractor the stopping distance increases. Determine the maximum

transport speed not to exceed 20 mph (30 kph) for transporting this equipment.

Test the equipment at a slow speed in turns. Increase the speed through the turn only after

you determine that the equipment can be operated at a higher speed. Use extreme care

and reduce your speed when turning sharply to prevent the tractor and implement from

turning over. Determine the maximum turning speed for you and this equipment before

operating on roads or uneven ground.

Only transport the Tractor and Implement at the speeds which allow you to properly control

the equipment.

Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes

or worn tires. When operating down a hill or on wet or rain slick roads, the braking distance

increases: use extreme care and reduce your speed. When operating in traffic always use

the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around you

and watch out for the other guy.

(SG-19)

OPERATION

TW144 01/11 Operation Section 4-30

OPERATION

9.1 Starting the Tractor

The procedure to start the tractor is model specific.

Refer to the tractor operator’s manual for starting

procedures for your particular tractor. Consult an

authorized dealer if the starting procedure is

unclear. Ensure the 3-point control lever is in the

lowered position and the PTO is disengaged before

starting the tractor. OPS-U-0033

9.2 Brake and Differential Lock Setting

Make sure the tractor brakes are in good operating

condition. Tractor brakes can be set to operate

independently allowing single rear wheel braking

action or locked together to provide simultaneous

rear wheel braking. FOR MOST DRIVING AND

OPERATING CONDITIONS, THE BRAKE PEDALS

SHOULD BE LOCKED TOGETHER TO PROVIDE

THE MOST EFFECTIVE BRAKING ACTION.

Always disengage the tractor differential lock when

turning. When engaged the differential lock will

prevent or limit the tractor from turning. During

normal cutting conditions, locking the differential

provides no benefit and should not be used. OPS-

U- 0013

Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes.

When operating down a hill or on wet or rain slick roads, the braking distance increases; use

extreme care and reduce your speed in these conditions. When operating in traffic, always

use the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around

you and watch out for the other guy.

OPERATION

TW144 01/11 Operation Section 4-31

OPERATION

9.3 Raising the Mower

Using the tractor 3-point hitch control lever-lift type

or hydraulic remote lever-pull and semi-mount

type, raise the mower high enough to clear all

ground obstacles. When raising the mower, make

sure all connection points are securely attached

and at least 1” clearance is maintained between the

driveline and the deck. If necessary, place an

upper lift stop on the 3-point hitch control lever to

limit the height the mower can be raised to avoid

driveline damage.

OPS-R-0042_A

9.4 Driving the Tractor and Mower

Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the

tractor and mower. Moving slowly at first will also prevent the tractor from rearing up and loss of steering

control. The tractor should never be operated at speeds that cannot be safely handled or which will prevent

the operator from stopping quickly during an emergency. If the power steering or engine ceases operating,

stop the tractor immediately as the tractor will be difficult to control.

Perform turns with the tractor and mower at slow

speeds to determine how the tractor with an

attached mower handles a turn. Determine the

safe speed to maintain proper control of the tractor

when making turns. When turning with a towed

implement, the overall working length of the unit is

increased. Allow additional clearance for the

mower when turning.

To avoid overturns, drive the tractor with care and

at safe speeds, especially when operating over

rough ground, crossing ditches or slopes, and

turning corners. Tractor wheel tread spacing

should be increased when working on inclines or

rough ground to reduce the possibility of tipping.

Use extreme caution when operating on steep

slopes. Keep the tractor in a low gear when going

downhill. DO NOT coast or free-wheel downhill.

OPS-R-0019

OPERATION

TW144 01/11 Operation Section 4-32

OPERATION

9.5 Crossing Ditches and Steep Inclines

When crossing ditches with steep banks or going up

sharp inclines, it is possible that the main driveline

inner profile will penetrate into the outer housing to its

maximum depth until the assembly becomes solid

(driveline is at its extreme shortest length). This type

of abusive operation can cause serious damage to

the tractor and mower drive by pushing the PTO into

the tractor and through the support bearings or

downward onto the PTO shaft, breaking it off.

Damage resulting from over-collapse of the driveline’s inner profile and its outer housing

may allow the driveline to come loose from the Tractor which could cause bodily injury to the

operator or bystanders and/or extensive damage to the Tractor or Implement. OPS-R-0020

When confronted with an incline or ditch, do not

approach from an angle which is perpendicular or

straight on as damage to or over-collapse of the

driveline may occur. OPS-R-0021_A

OPERATION

TW144 01/11 Operation Section 4-33

OPERATION

Inclines and ditches should be approached along a

line which is at an angle as shown. This type of

path will reduce the possibility of over-collapse of

the driveline and resulting damage. If the gradient

is so steep that such an approach increases the

possibility of a tractor roll-over, select an alternate

crossing path.

When operating the tractor and mower across

slopes and inclines, through ditches, and other

uneven terrain conditions, it is important to maintain

sufficient deck to ground clearance. Blade contact

with the ground may cause soil, rocks and other

debris to be thrown out from under the mower

resulting in possible injury and/or property damage.

Ground contact also produces a severe shock load

on the mower drive and to the mower blades

resulting in possible damage and premature wear.

OPS-R-0022

10. OPERATING THE TRACTOR AND IMPLEMENT

THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND

IMPLEMENT AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE. The operator must read and

understand the Safety and Operation Sections of the implement and tractor operator’s manuals. These

manuals must be read and explained to any operator who cannot read. Never allow someone to operate the

implement and tractor without complete operating instructions.

Before starting any operation, the operator must become familiar with the area to be worked in and any

obstacles and hazards contained within to ensure safety to the operator, bystanders, and equipment. Special

attention should be paid to foreign debris, rough terrain, steep slopes, and passersby and animals in the area.

OPS-U- 0015

Extreme care should be taken when operating near loose objects such

as gravel, rocks, wire, and other debris. Inspect the area before

mowing. Foreign objects should be removed from the site to prevent

machine damage and/or bodily injury or even death. Any objects that

cannot be removed must be clearly marked and carefully avoided by the

operator. Stop mowing immediately if blades strike a foreign object.

Repair all damage and make certain rotor or blade carrier is balanced

before resuming mowing.

(SGM-05)

OPERATION

TW144 01/11 Operation Section 4-34

OPERATION

Many varied objects, such as wire, cable, rope, or chains, can become entangled in the

operating parts of the mower head. These items could then swing outside the housing at

greater velocities than the blades. Such a situation is extremely hazardous and could result

in serious injury or even death. Inspect the cutting area for such objects before mowing.

Remove any like object from the site. Never allow the cutting blades to contact such items.

(SGM-06)

10.1 Foreign Debris Hazards

Before mowing, inspect the area to make sure

there are no foreign objects that the mower blades

could hit or become entangled with. Remove all

foreign objects and debris. If objects are too big to

remove, mark them clearly and be sure to prevent

the mower blades from contacting them.

If you hit a solid object or foreign debris, stop the

mower and tractor at once. Immediately idle the

engine speed and disengage the PTO. Wait for all

mower rotating motion to stop, then raise the

mower and move the tractor and implement off the

object. Inspect the area and remove, or mark the

location of the debris. Inspect the condition of the

mower and make any needed repairs immediately.

Make sure the blades are not damaged and the

carrier is balanced before resuming operation.

Always wear your seat belt securely fastened and

only operate the tractor and mower with the ROPS

in the raised position. If the tractor or mower hits a

tree stump, rock, or bump, a sudden movement

could throw you off of the seat and under the

tractor and/or mower. The seat belt is your best

protection from falling off the tractor and the ROPS

provides protection from being crushed during a

tractor roll-over. OPS-R-0023

Remove Foreign Material

Raise Mower over solid objects

10.2 Bystanders/Passersby Precautions

If a bystander comes within 300 feet of the tractor while the mower is being operated, stop the tractor at once,

idle the engine and disengage the PTO. Do not engage the PTO again until all bystanders are well past the

300 foot distance. OPS-R-0024

OPERATION

TW144 01/11 Operation Section 4-35

OPERATION

Rotary Mowers are capable under adverse conditions of throwing

objects for great distances (300 feet or more) and causing serious injury

or death. Follow safety messages carefully.

STOP MOWING IF PASSERSBY ARE WITHIN 300 Feet UNLESS:

-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable

condition;

-Mower sections or Wings are running close to and parallel to the ground without exposed

Blades;

-Passersby are outside the existing thrown-object zone;

-All areas have been thoroughly inspected and all foreign material such as rocks, cans,

glass, and general debris has been removed.

NOTE: Where there are grass and weeds high enough to hide debris that could be struck

by the blades, the area should be: inspected and large debris removed, mowed at an

intermediate height, inspected, closely with any remaining debris being removed, and

mowed again at desired final height. (This will also reduce power required to mow, reduce

wear and tear on the Mower drivetrain, spread cut material better, reduce streaking, and

make the final cut more uniform).

(SRM-01)

10.3 Engaging the Power Take Off (PTO)

Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The implement

must be completely lowered and the deck positioned at a safe operating height. NEVER engage the PTO with

the implement in the raised position.

Set the tractor engine speed at approximately 1,000 RPM before engaging the PTO. Shift the PTO control to

the on position, and slowly increase the engine speed until the PTO is operating at the rated speed. If you

hear unusual noises or see or feel abnormal vibrations, disengage the PTO immediately. Inspect the

implement to determine the cause of the noise or vibration and repair the abnormality. OPS-U- 0027

Do not let the Blades turn when the Mower Deck is raised for any

reason, including clearance or for turning. Raising the Mower deck

exposes the Cutting Blades which creates a potentially serious hazard

and could cause serious injury or even death from objects thrown from

the Blades.

(SRM-07)

Do not put hands or feet under mower decks. Blade Contact can result

in serious injury or even death. Stay away until all motion has stopped

and the decks are securely blocked up.

(SGM-09)

OPERATION

TW144 01/11 Operation Section 4-36

OPERATION

10.4 PTO RPM and Ground Speed

Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut.

Recommended speed for efficient mower performance is between 2 and 5 mph(3-8 kph). Operate the mower

at its full rated PTO speed to maintain blade speed for a clean cut. Refer to the tractor operator’s manual or

the tractor instrument panel for the engine speed and gear to provide the required PTO and desired ground

speed. Make sure that the mower is operating at its full rated speed before entering the vegetation to be cut.

If it becomes necessary to temporarily regulate engine speed, increase or decrease the throttle gradually.

Ground speed is achieved by transmission gear selection and not by the engine operating speed. The

operator may be required to experiment with several gear range combinations to determine the best gear and

range which provides the most ideal performance from the mower and most efficient tractor operation. As the

severity of cutting conditions increase, the ground speed should be decreased by selecting a lower gear to

maintain the proper operating PTO speed. OPS-R-0025

Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause

Implement driveline or blade failures resulting in serious injury or death.

(SG-26)

Mow at the speed that you can safely operate and control the tractor and mower. The

correct mowing speed depends on terrain condition and grass type, density, and height of

cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds

when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power

lines, or when debris and foreign objects are to be avoided.

(SGM-07)

10.5 Operating the Mower

The mower is designed to cut vegetative material up to 2” in diameter. Travel at a speed that allows the

mower sufficient time to cut through the vegetation and maintain the operating speed at 540 rpm to prevent

overloading the mower and tractor and to produce a clean cut. Choose a driving pattern that provides the

maximum pass length and minimizes turning. Remember, sharp blades produce cleaner cuts and require

less power.

Under certain conditions, tractor tires may roll some grasses down preventing them from being cut at the

same height as the surrounding area. When this occurs, reduce the tractor ground speed while maintaining

the operating speed of the mower. A slower ground speed will permit grasses to at least partially rebound and

be cut. Taking a partial cut and/or reversing the direction of travel may also help produce a cleaner cut.

Avoid mowing in the reverse direction when possible. In situations where the mower must be backed to

access areas to be cut, make sure there are no persons or other foreign debris behind the mower before

mowing in reverse. When mowing in reverse, operate the tractor and mower at a much reduced ground

speed to ensure control is maintained of the tractor and cutter. OPS-R-0026_H

OPERATION

TW144 01/11 Operation Section 4-37

OPERATION

Do not mow with two machines in the same area except with Cab tractors with the windows

closed.

(SGM-11)

Mow only in conditions where you have clear visibility in daylight or with adequate artificial

lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least

300 feet (90 m) in front and to the sides of the tractor and mower. Make sure that you can

clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions,

power lines, debris and foreign objects. If you are unable to clearly see these type of items

discontinue mowing.

(SGM-1)

Avoid mowing in reverse direction when possible. Check to make sure there are no

persons behind the mower and use extreme care when mowing in reverse. Mow only at a

slow ground speed where you can safely operate and control the tractor and mower.

Never mow an area that you have not inspected and removed debris or foreign material.

(SGM-08)

Follow these guidelines to reduce the risk of equipment and grass fires

while operating, servicing, and repairing the Mower and Tractor:

-Equip the Tractor with a fire extinguisher in an accesible location.

-Do Not operate the Mower on a Tractor with an underframe exhaust.

-Do Not smoke or have an open flame near the Mower and Tractor.

-Do Not drive into burning debris or freshly burnt areas.

-Ensure slip clutches are properly adjusted to prevent excessive slippage and plate heating.

-Never allow clippings or debris to collect near drivelines, slip clutches, and gearboxes.

Periodically shut down the Tractor and Mower and clean clippings and collected debris from

the mower deck.

(SGM-12)

When you get to the end of a pass, slightly raise the

mower (2-4”) before turning. Never raise the

mower entirely while the blades are turning. If the

mower must be raised higher than 12” from ground

level, disengage the tractor PTO and wait for all

mower rotation to come to a complete stop before

proceeding to raise the mower. OPS-R-0027_B

OPERATION

TW144 01/11 Operation Section 4-38

OPERATION

Do not let the Blades turn when the Mower Deck is raised for any

reason, including clearance or for turning. Raising the Mower deck

exposes the Cutting Blades which creates a potentially serious hazard

and could cause serious injury or even death from objects thrown from

the Blades.

(SRM-07)

Large, dense, or wet vegetation may need to be

mowed in two or more passes to achieve a uniform

cut. In such conditions, raise the cutting height to

12” or more on the first pass

. OPS-R-0043

Then lower the mower to the desired height and

mow the vegetation a second time. If possible,

select a mowing pattern that is at a 90 degree angle

to the first pass to reduce streaking for a more

uniform cut. OPS-R-0044

OPERATION

10.6 Right of Way (highway) Mowing

• USE DOUBLE CHAIN GUARDS for highway, right-of-way, parks, greenbelt mowing, or all other mowing

where human dwellings, vehicles, or livestock could be within 300 feet of the mower.

• No shielding is 100% effective in preventing thrown objects. To Reduce Possibility of Injury:

1. MAINTAIN MOWER SHIELDING in good operational condition,

2. DAILY INSPECT the condition of the Thrown Object Guards, mower Side Skirts, and skid shoes:

Replace or repair worn or damaged guards.

3. DAILY INSPECT the condition of the Blades and Blade Bolts. Replace any cracked, worn, bent or

damage blades. Always replace blade bolts and nuts when replacing blades. Make sure the blade

bolts are properly tightened.

4. RAISE CUTTING HEIGHT to 6 INCHES minimum.

5. INSPECT AREA thoroughly before mowing to REMOVE potential THROWN OBJECT HAZARDS.

6. NEVER ALLOW BLADES to CONTACT SOLID OBJECTS like wire, rocks, posts, curbs, guardrails,

or ground while mowing.

ROTARY MOWERS CAN THROW OBJECTS 300 FEET OR MORE UNDER ADVERSE

CONDITIONS.

TO AVOID SERIOUS INJURY OR DEATH TO OPERATOR OR BYSTANDERS FROM THROWN

OBJECTS:

INSPECT AREA FOR POTENTIAL THROWN OBJECTS BEFORE MOWING:

• REMOVE debris, rocks, wire, cable, metal objects and other foreign material from area.

Wire, cable, rope, chains and metal objects can be thrown or swung outside deck with great velocity:

1. MARK objects that cannot be removed.

2. AVOID these objects when mowing.

STOP MOWING IF PASSERSBY IS WITHIN 300 FEET UNLESS:

• All THROWN OBJECT SHIELDING including Front and Rear Deflectors, Chain Guards, Steel Guards,

Bands, Side Skirts and Skid Shoes are in place and in good condition when mowing.

• Mower sections or wings are adjusted to be close and parallel to ground without exposing blades.

• MOWING AREA has been inspected and foreign materials and debris have been removed.

• PASSERSBY are inside enclosed vehicle. OPS-U-0040

OPERATION

TW144 01/11 Operation Section 4-40

OPERATION

Never stand or allow another person to stand between a running Tractor and the Mower

when disconnecting the Implement from the Tractor 3-point hitch.

10.7 Shutting Down the Implement

To shut down attached mower head, first bring the

tractor to a complete stop. Decrease engine RPM

to idle then disengage cutterhead. The mower head

will come to a complete stop within a suitable

amount of time. Do not engage or disengage the

cutterheads at a high RPM unless there is an

emergency situation.

Park the tractor on a level surface, place the

transmission in park or neutral and apply the

parking brake, lower the attached implement to the

ground, shut down the engine, remove the key, and

wait for all motion to come to a complete stop

before exiting the tractor. OPS-U- 0016

11. DISCONNECTING THE MOWER FROM THE TRACTOR

Before disconnecting the mower, the PTO must be

disengaged and blade rotation at a complete stop.

Move the mower to a level storage location and

lower it to the ground. If the mower is not resting

securely on the ground, block the mower up

securely before attempting to disconnect it from

the tractor.

Use extreme care to keep feet and hands from

under the mower and clear of any pinch points

caused by the tractor hitch arms and mower pins.

OPS-R-0030_A

OPERATION

TW144 01/11 Operation Section 4-41

OPERATION

Always shut the Tractor completely down, place the transmission in park, and set the

parking brake before you or anyone else attempts to connect or disconnect the Implement

and Tractor hitches.

(S3PT-15)

Never unhitch without using the Tongue Jack. The Tongue is very heavy. Attempting to lift

the Tongue without using the Tongue Jack could cause strains or other injury. Allowing the

tongue to fall suddenly and unexpectedly could result in crushing injury. Use the Tongue

Jack for lifting the Implement only. Overloading the Tongue Jack can cause failure with

possible serious bodily injury or even death.

(STI-04)

Lift-Type Mower - To disconnect the mower, first

extend the tractor 3-point hitch top link to remove

tension on the top link hitch pin. When the pin is

loose and easy to rotate, remove the pin from the

mower. Next remove both lower hitch pins.

Pull-Type Mower - To disconnect the mower, first

relieve hydraulic pressure by moving the control

lever back and forth several times. Lower the

parking jack and raise the mower until the tongue

clevis in no longer resting on the tractor drawbar

and is supported solely by the jack. Make sure that

the jack foot is securely resting at ground level or

supported by a block. Then remove the hitch bolt,

locknut, and washers. If a hydraulic cylinder was

used, remove its hose end from the tractor port and

secure it to the mower to prevent contact with dirt.

After disconnecting the 3 lift points, remove the

mower driveline from the tractor PTO shaft. Lay the

driveline down carefully to avoid damaging the

driveline or its shield. Do not let the driveline fall

into mud or dirt, which can contaminate the bearing

and shorten the life of the driveline. OPS-R-0031_A

OPERATION

TW144 01/11 Operation Section 4-42

OPERATION

12. MOWER STORAGE

Properly preparing and storing the mower at the end of the season is critical to maintaining its appearance

and to help ensure years of dependable service. The following are suggested storage procedures:

• Thoroughly clean all debris off the mower to

prevent damage from rotting grass and

standing water.

• Lubricate all mower grease points and fill

gearbox oil levels as detailed in the

maintenance section.

• Tighten all bolts and pins to the recommended

torque.

• Check the mower for worn and damaged

parts. Perform repairs and make

replacements immediately so that the mower

will be ready for use at the start of the next

season.

• Store the mower in a clean, dry place with the

mower housing resting securely on blocks or

at ground level.

• Keep the driveline yoke from sitting in water, dirt and other contaminants.

• Use spray touch-up enamel where necessary to prevent rust and maintain the appearance of the mower.

It is critical that driveline clutches slip when an obstacle or heavy load is encountered to avoid mower and/or

tractor damage. If the mower sits outside for an extended period of time or is exposed to rain and/or humid

air, the clutch lining plates must be inspected to ensure they are not frozen together from rust or corrosion. If

the mower has been exposed to such conditions, at the start of each mowing season, and any time it is

suspected that the slip clutch plates may be frozen together, readjust the slip clutch as detailed in Seasonal

Clutch Maintenance of the maintenance section in this manual. OPS-R-0032_A

Never allow children or other persons to ride on the Tractor or Implement.

Falling off can result in serious injury or death.

(SG-10)

13. TRANSPORTING THE TRACTOR AND IMPLEMENT

Inherent hazards of operating the tractor and implement and the possibility of accidents are not left behind

when you finish working in an area. Therefore, the operator must employ good judgement and safe operation

practices when transporting the tractor and implement between locations. By using good judgement and

following safe transport procedures, the possibility of accidents while moving between locations can be

substantially minimized. OPS-U- 0017

OPERATION

TW144 01/11 Operation Section 4-43

OPERATION

Before transporting the tractor and mower, idle the

tractor engine, disengage the PTO and wait for all

mower moving parts to come to a complete stop.

Once all mower parts are completely stopped, raise

the mower to transport height. NOTE: When

raising the mower, maintain 1” clearance between

the driveline and mower deck. If additional mower

deck height is needed for safe transport, disconnect

the driveline from the tractor and secure its end to

the mower deck. The mower can then be raised to

the maximum lift height. OPS-R-0033_A

If the tractor’s hydraulic pump is not independent of

the tractor PTO, or if the tractor PTO has to be run

to have hydraulic power, disconnect the mower

driveline from the tractor PTO output shaft. Secure

the driveline to the mower deck to prevent driveline

damage or loss during transport. OPS-R-0034

13.1 Transporting on Public Roadways

Extreme caution should be used when transporting the tractor and implement on public roadways. The tractor

must be equipped with all required safety warning features including a SMV emblem and flashing warning

lights to alert drivers of the tractor’s presence. Remember that roadways are primarily designed for

automotive drivers and most drivers will not be looking out for you, therefore, you must look out for them.

Check your side view mirrors frequently and remember that vehicles will approach quickly because of the

tractor’s slower speed. Be extremely cautious when the piece of equipment that you are towing is wider than

the tractor tire width and/or extends beyond your lane of the road.

Make sure that a proper size safety tow chain is secured between the tractor and implement before entering a

public road. OPS-U- 0019

Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in

such a way as to be clearly visible and legible. When transporting the

Equipment use the Tractor flashing warning lights and follow all local

traffic regulations.

(SG-6)

OPERATION

TW144 01/11 Operation Section 4-44

OPERATION

The SMV (Slow-Moving Vehicle) emblem is

universal symbol used to alert drivers of the

presence of equipment traveling on roadways at a

slow speed. SMV signs are a triangular bright

orange with reflective red trim for both easy day

and night visibility. Make sure the SMV sign is

clean and visible from the rear of the unit before

transporting the tractor and implement on a public

roadway. Replace the SMV emblem if faded,

damaged, or no longer reflective. OPS-U- 0020

Make sure that all tractor flashing warning lights,

headlights, and brake/tail lights are functioning

properly before proceeding onto public roads. While

newer model tractors have plenty of lighting to

provide warning signals and operating lighting, most

older models are only equipped with operating lights.

Consult an authorized tractor dealer for lighting kits

and modifications available to upgrade the lighting on

older tractor models. OPS-U- 0021

When operating on public roads, have

consideration for other road users. Pull to the side

of the road occasionally to allow all following traffic

OPERATION

13.2 Hauling the Tractor and Implement

Before transporting a loaded tractor and implement, measure the height and width dimensions and gross

weight of the complete loaded unit. Ensure that the load will be in compliance with the legal limits set for the

areas that will be traveled through

Use adequately sized and rated trailers and equipment to transport the tractor and implement. Consult an

authorized dealer to determine the proper equipment required. Using adequately sized chains, heavy duty

straps, cables and/or binders, securely tie down both the front and rear of the tractor utilizing the proper tie

down locations as specified by the tractor manufacturer.

Arrange the chains so that when tightened, the chains are pulling downward and against themselves. Carefully

tighten the securing chains or other fasteners using boomers or binders to apply maximum tension. Use

extreme care when attaching and removing the securing devices as the extreme tension involved when

released has the potential to inflict serious injury.

While hauling the tractor and implement, make occasional stops to check that the tractor and implement have

not moved or shifted and that the securing chains have maintained tension. If during transport a hard braking,

sharp turning, or swerving action was performed, stop at the next safe location to inspect the security of the

load.

Reduce speed before turning or applying the brakes.

Ensure that both brake pedals are locked together

when operating on public roads. OPS-U- 0023

MAINTENANCE

Before operating your Rotary Cutter, make sure it is properly lubricated and thoroughly inspected. Only a

minimum of time and effort is required to regularly lubricate and maintain this machine to provide long life and

trouble free operation.

Always disengage the PTO before raising the Rotary Cutter for transporting or making

adjustments.

Lubrication

Do not let excess grease collect on or around parts, particularly when operating in sandy areas. The

illustrations below shows lubrication points (Figure Mnt-R-0393/Mnt-R-0394). The chart gives the frequency of

lubrication in hours, based on normal operating conditions. Severe or unusual conditions may require more

frequent lubrication.

Use Multi-Purpose Gear Oil P/N 00786250 when required in Gearbox. Use N.L.G.I #2 grease for all locations

designated with grease gun. Be sure to clean the fitting thoroughly before using grease gun. Failure to

maintain proper lubrication will result in damage to U-joints, gearbox, and/or driveshaft.

PARTS INFORMATION

Rhino mowers use balanced and matched system components for blade carriers, blades, cuttershafts, knives,

knife hangers, rollers, drivetrain components, and bearings. These parts are made and tested to Rhino speci-

fications. Non-genuine "will fit" parts do not consistently meet these specifications. The use of “will fit” parts

may reduce mower performance, void warranties, and present a safety hazard. Use genuine Rhino mower

parts for economy and safety.

GEARBOX

The Gearbox has been filled with lubricant to the Test Plug Level prior to shipment. However, you should check

the oil level at Test Plug before operating, and frequently thereafter.

The gearbox should not require additional lubricant unless the box is cracked or a seal is leaking. It is

recommended that the oil level plug be removed after every 8 to 10 hours of operation and oil added until it

runs out Test Plug hole. The Test Plug is located on the rear of the Gearbox. Filler Plug is located on top of

Gearbox. See Figure MntP-0001& Mnt-R-0117.

Use Multi-Purpose Gear Oil P/N 00786250 for all locations shown according to instructions.

NOTE: Overfilling the Gearbox will cause pressure to build up and cause Oil Seals to leak.

ATTENTION: If the Gearbox suddenly starts making an unusual noise, stop at once, check for leaks, and refill

Gearbox as required.

TAIL WHEEL ASSEMBLY

Tail Wheel Bearings are packed at the factory with

heavy-duty bearing grease. Grease Fittings are

provided in the Wheel Hub and Tail Wheel Beam.

DRIVELINES

Many of the equipment components are HEAVY (70 lbs or greater) and Special Lifting

Procedures are recommended. Use lifting assistance such as mechanical assistance, two

people, and proper lifting techniques when connecting or installing the driveshaft to reduce

the possibility of back injuries.

The Drivelines and U-Joints should be inspected each morning before the mower is started.

The U-Joint and CV Joint on the Driveline undergo extreme forces when the unit is turning or when the Wings

are being raised. It is important that the U-Joints and CV Joint be greased per schedule before the unit is

started. The U-Joints are located at each end of the Center and Wing Drivelines. The CV Joint is located at the

end of the Main Driveline. The U-Joint and CV Joint assemblies are accessible by rotating the Driveline Safety

Shield until the hole in the Shield matches up with the Grease Fitting. Lubricate all fittings with a good quality

Lithium Soap compatible E.P. grease meeting the N.L.G.I. #2 specifications and containing no more than 1%

Molybdenum Disulfide. An E.P. grease meeting the N.L.G.I. #2 specifications and containing 3% Molybdenum

Disulfide may be substituted in the telescoping members only. Inspect the U-Joint for wear by holding the shaft

on one side of the U-Joint while trying to rotate the shaft on the other side of the U-Joint. If there is noticeable

movement in the Driveline replace the U-Joint before it causes severe damage to the Driveline.

BLADE SERVICING

Inspect blades before each use to determine that they are properly installed and in good condition. Replace

any blade that is bent, excessively nicked, worn, or has any other damage. Small nicks can be ground out

when sharpening.

Use only original equipment blades on this cutter. They are made of special heat-treated

alloy steel. Substitute blades may not meet specifications and may fail in a hazardous

manner that could cause injury.

Replace bent or broken blade with new blades. NEVER ATTEMPT TO STRAIGHTEN OR

WELD ON BLADES SINCE THIS WILL LIKELY CRACK OR OTHERWISE DAMAGE THE

BLADE WITH SUBSEQUENT FAILURE AND POSSIBLE SERIOUS INJURY FROM

THROWN BLADES.

(SGM-10)

• Manually wiggle the glade carriers to check for any looseness.

• Retighten any loose parts.

• Recheck torque every 50 hours.

Operating with loose blade hardware will damage the blade holder and blades. Whenever

the blades have been removed or replaced, the hardware must be retightened after the first

eight hours of operation. On new units check blade hardware and the blade nut torque after

first 8 hours.

Operating with loose blade holder will damage the blade holder and output shaft, two initial

tightenings are required. Retighten after one hour and again after the day of operation. In

severe cutting conditions or commercial use, a daily inspection is required.

To help prevent structural damage caused by loose hardware, tighten gear case hardware

as specified. Check torque after first 8 hours of use and every 50 hours thereafter.

NOTE: Replace Blades in pairs after no more than 1/2” notch wear!

MAINTENANCE

TW144 01/11 Maintenance Section 5-12

MAINTENANCE

BLADE SHARPENING

Always sharpen both blades at same time to maintain balance. Follow original sharpening pattern as shown in

Mnt-R-0008. Always sharpen blades by grinding. DO NOT heat and pound out edge. Do not sharpen blade to

a razor edge, but leave a 1/16” blunt edge. Do not sharpen back side of blade.

Avoid personal injury. Always block the cutter up to prevent if from falling when the blades

and/or carrier are being serviced.

Do not heat or weld on hard surface blades as this can alter material strength causing

blades to fail in a hazardous manner that could cause injury.

BLADE REMOVAL

To remove blades for sharpening or replacement, remove the cover plate (see Mnt-R-0168) on deck of cutter

near gear box. Remove lock nut from blade bolt. NOTE: Inspect lock nut after removal and replace if threads

are damaged. Always replace nut when replacing blade bolt. When installing blades be sure and check blade

bolt pivot diameter for wear. Replace bolt if worn more than 1/4 inch at any point.See Mnt-R-0014. Install blade

bolts with partially worn side of bolt either toward or away from center. Tighten lock nut to 250 ft. lbs.

Avoid personal injury. Blade and/or blade carrier removal should be done only with the

tractor engine shut off, key removed, in neutral, parking brake on, and PTO disengaged and

the cutter blocked in the raised position.

BLADE CARRIER REMOVAL

Remove cotter pin and loosen slotted nut on gearbox shaft. Loosen but do not remove the nut until the blade

carrier is loosened. Use a suitable 2 jaw gear puller to pull carrier off tapered gearbox shaft. If gear puller is not

available use long bar inserted through blade bolt access hole with end against rotor bar. Strike opposite end of

bar with sledge hammer. Rotate blade carrier 180 degrees and repeat process.

MAINTENANCE

TW144 01/11 Maintenance Section 5-13

MAINTENANCE

Blade Bolt Inspection

Inspect Blade Bolt Head daily for wear as followed:

Inspect the Blade Bolt Heads daily for abnormal wear. REPLACE BOTH BLADE BOLTS on

the Blades IMMEDIATELY if either blade bolts has:

• Visible cracks or

• If the recessed area on blade bolt is worn off or

• If Blade Bolt has gouges or chipped areas.

Failure to replace abnormally worn blade bolts may lead to catastrophic failure of the blades and ejection of

the broken part which may cause serious bodily injury or death.

Always replace Blade Bolts with new bolts whenever replacing the Blades. OPS-U-0037

MAINTENANCE

TW144 01/11 Maintenance Section 5-14

MAINTENANCE

BLADE CARRIER INSTALLATION

Clean the splines on both the blade carrier and output shaft. Position carrier on the gearbox output shaft and

install special washer, and nut.

Tighten nut holding blade carrier to minimum 450 ft. pounds, strike the carrier near the hub several times with a

heavy hammer to seat the hub. Use a suitable spacer over the nut to prevent damage to the nut and threads.

Retighten the nut to 450 ft. pounds. Install cotter pin and spread.

Operating the mower with a loose blade pan or holder can damage the taper connection on

the gearbox output shaft. To ensure proper seating between the blade holder and output

shaft, check and tighten the retaining nut after the first day of operation. Recheck the blade

carrier attachment each morning before operating. Grasp the carrier firmly with both hands

and try to push and pull the carrier with one hand while pulling and pushing with the other

hand to try to rock or oscillate the blade carrier. If the carrier is loose, retighten the retaining

nut before operating the mower.

Always recheck gearbox output shaft slotted blade carrier retaining nut torque after a few

hours operation.

Avoid personal injury. Do not work under cutter without support blocks to keep frame from

falling.

BLADE CARRIER INSPECTION

Blade bolt fit into carrier bushings should be checked every time blades are changed. The blade bolt should fit

into carrier bushings as a snug slip fit. If the blade bolt fit appears to be loose or sloppy, measure the square

hole in bushing. If the bottom of the square hole is 1/16” or greater than the square shoulder of the new blade

bolt the bushings should be replaced. Bushings can be removed by cutting bushing head where it is welded to

carrier bar. Once head is removed bushing can be pressed out of bar. Clean and grind top of blade bar so new

bushing can be installed and welded. Bushing should be pressed into bar as far as possible. Use low hydrogen

rod to weld bushing in place.

Failure to replace a worn blade carrier bushing as described above may lead to catastrophic

failure of the blade, blade bolt, and/or blade bolt nut resulting in the ejection of the broken

parts out from under the mower at tremendous speed and force which could result in serious

bodily injury or death.

MAINTENANCE

TW144 01/11 Maintenance Section 5-15

MAINTENANCE

BLADE TIMING AND ROTATION

(Mnt-R-0102)

Blades on multi-spindle mowers overlap cutting paths to ensure a complete cut across the width of the mower

and to compensate for blade tip wear. If a gearbox has been repaired, a blade carrier or side driveline has been

removed, or other maintenance performed which altered the factory set blade carrier timing, the blades must

be re-timed to ensure they will not collide while rotating.

BLADE TIMING PROCEDURE

1. Raise the mower to minimum height to allow sufficient clearance between the mower deck and ground to

visually inspect blade carriers.

2. Completely shut down the tractor and secure the tractor in position by placing the tractor in park and

setting the parking brake. Securely block the mower at this height.

3. On a side gearbox, remove connecting driveline coupler.

4. Manually rotate carriers until blades are positioned at near 90 degree angle from one another. See Fig.

Mnt-R-0102

5. Replace connecting driveline and coupler.

6. Manually spin carriers a complete rotation to ensure blades do not collide with one another.

MAINTENANCE

TW144 01/11 Maintenance Section 5-16

MAINTENANCE

SLIP CLUTCH

A slip clutch is incorporated in the PTO driveline. It is designed to slip, absorb the shock load, and protect the

driveline.

After the first hour of operation, the slip clutch should be checked for overheating. After this first check, the slip

clutch should be checked weekly or anytime there is overheating. To adjust the slip clutch, tighten the spring

bolts to 1-9/16” length. Any increase or decrease in this tightness will change the torque rating and could

cause premature failure.

The slip clutch should be checked periodically and adjusted to compensate for wear. The lining plates are 1/8”

thick when new. Replace after 1/16” wear. If the mower has been idle for an extended period of time, or in wet

weather, before operating check to be sure the friction lining plates are not frozen or rusted together. Should

this freezing occur refer to the procedure described in the “Seasonal Clutch Maintenance” section on the next

page.

There are two friction lining plates in the slip clutch. These should be checked weekly for oil or grease, wear,

and moisture which could cause corrosion on the drive plates.

SEASONAL CLUTCH MAINTENANCE

It is important that the clutches slip when an obstacle or load heavier than the clutch setting is encountered.

Before using the cutter each season, use the following procedure to make sure the clutch will slip and give the

overload protection required.

1. Loosen nuts (Figure Mnt-0007) on springs until the springs can freely rotate, yet remain secure on bolts.

2. Attach mower to tractor and start the tractor. Set the engine speed at 1200 RPM.

3. Engage the PTO (approximately one second) and then quickly disengage it. The friction lining plates

should break loose.

4. Turn tractor off and tighten the nuts on the springs to their original position of 1-9/16” compressed spring

length.

MAINTENANCE

TW144 01/11 Maintenance Section 5-17

MAINTENANCE

STORAGE

Your rotary cutter represents an investment from

which you should get the greatest possible benefit.

Therefore, when the season is over, the cutter

should be thoroughly checked and prepared for

storage so that a minimum amount of work will be

required to put it back into operation for the next

season. The following are suggested storage

procedures:

1. Thoroughly clean the cutter.

2. Lubricate the cutter as covered in Maintenance

Section.

3. Tighten all bolts and pins to the recommended

torque.

4. Check the cutter for worn or damaged parts.

Make replacements immediately.

5. Place driveline in storage position resting on

bracket.

6. Store the cutter in a clean, dry place with the

cutter housing resting on blocks.

7. Use spray touch-up enamel where necessary to

prevent rust and maintain the appearance of

the cutter.

PROPER TORQUE FOR FASTENERS

The chart lists the correct tightening torque for fasteners. When bolts are to be tightened or replaced, refer to

this chart to determine the grade of bolts and the proper torque except when specific torque values are

assigned in manual text.

RECOMMENDED TORQUE IN FOOT POUNDS UNLESS OTHERWISE STATED IN THE MANUAL*

NOTE: These values apply to fasteners as received from supplier, dry or when lubricated with normal engine

oil. They do not apply if special graphited or molydisulphide greases or other extreme pressure lubricants are

used. This applies to both UNF fine and UNC coarse threads.

Video de cortadora AEM

A fin de reducir la tasa de accidentes y mejorar la operación segura de las cortadoras, Alamo Group Ag Division

se ha asociado con otros fabricantes de la industria para desarrollar el video y la guía de Prácticas de Seguridad

para Cortadoras Industriales y Agrícolas AEM/FEMA.

El video explica a los operadores de tractores y cortadoras las prácticas seguras que deben adoptar cuando

utilizan cortadoras industriales y agrícolas. Es importante que todos los operadores de cortadoras aprendan

cómo operar sus equipos de corte y puedan reconocer los posibles peligros que pueden surgir al operar una

cortadora. Este video, en conjunto con el manual del operador de la cortadora y los mensajes de advertencia

que se encuentran en la cortadora, serán muy útiles para complementar este aprendizaje tan importante.

Es posible que su distribuidor autorizado de Rhino le haya mostrado este video y le haya entregado una copia

en DVD cuando adquirió su cortadora. Si usted o algún operador de cortadora no vio el video: mire el video, lea

este Manual del Operador, y complete la Guía del Video antes de operar su cortadora nueva. Si no comprende

alguna de las instrucciones del video o del manual del operador, o si tiene alguna pregunta acerca de la

operación segura, comuníquese con su supervisor, con el distribuidor o con Alamo Group Ag.

Si desea recibir una copia del video en VHS, envíe un mensaje de correo electrónico a AEMVideo@alamo-

group.com o un fax al (830) 372-9529, o envíe por correo una copia rellenada del formulario que se encuentra al

dorso de esta página a AEM VHS Video 1502 E Walnut Street, Seguin, TX 78155, y solicite la versión en VHS.

Indique su nombre, dirección postal, modelo de cortadora y número de serie.

Cada uno de los operadores debe recibir capacitación para cada equipo (tractor y cortadora), comprender el uso

previsto, y comprender los posibles peligros antes de operar el equipo.

ANTES DE COMENZAR LEA, COMPRENDA y SIGA la información incluida en este manual, el Manual de

Seguridad de la Cortadora AEM y el manual del operador del tractor para conocer cómo operar la máquina y

realizar tareas de servicio correctamente. De lo contrario, podría sufrir lesiones u ocasionar lesiones a terceros.

Todos los implementos con partes móviles son potencialmente peligrosos. Cada esfuerzo ha sido hecho para

asegurar que la màquina esté segura, pero los operadores deben evitar entrar en prácticas peligrosas y seguir las

instrucciones escritas que son proporcionadas. El fabricante ha diseñado este implemento para ser usado con

todos sus equipos de seguridad correctamente sujetados para minimizar la probabilidad de accidentes.

LA SEGURIDAD PRIMERO. Lea con atención la totalidad de la sección de seguridad de este manual antes de

operar el equipo. No permita que nadie opere el equipo sin haber leído y comprendido la totalidad de este manual.

Comuníquese con el distribuidor si necesita explicación sobre alguna instrucción que no haya comprendido del

todo.

y la vida útil del equipo. Lea con atención y siga las instrucciones de este manual para comprender cabalmente su

nuevo implemento, su uso previsto, y sus requisitos de servicio.

Todas las referencias que se hacen en este manual a derecha, izquierda, frontal, trasero, arriba y abajo

La información sobre repuestos se encuentra por separado en el Manual de Partes. Las cortadoras Rhino utilizan

componentes del sistema equilibrados y coincidentes para porta cuchillas, cuchillas, ejes de corte, hojas, ganchos

para hojas, rodillos, componentes de los engranajes, y cojinetes. Estas partes se fabrican y se prueban según las

especificaciones de Rhino. Las partes compatibles no genuinas no siempre cumplen con estas especificaciones.

El uso de partes no genuinas puede perjudicar el desempeño de la cortadora, anular la garantía y presentar un

riesgo para la seguridad. Use partes genuinas Rhino para ahorrar dinero y maximizar la seguridad.

Para referencia futura, registre el número de modelo y el número de serie de RHINO que ha adquirido.
