Avoid Injury From Fire And Explosion

Set the parking brake, shut the mower and tractor

engine down and remove the key while  lling the fuel

tank. Use extra caution when fueling a hot engine.

Never smoke while fueling. Avoid sparks by grounding

the fuel nozzle against the  ller neck.

The fumes in an empty fuel tank are explosive. Never

weld or cut on fuel lines, tanks or containers.

Remove all trash or mowing debris from the machine

daily or as needed. Keep debris away from engine,

exhaust, slip clutches and other heat sources. Use

spark arrestors, as appropriate, on the engine exhaust

system. Make sure oily rags or other  ammable material

are not stored on the machine.

Check for fuel, oil or hydraulic  uid leaks. Repair the

leaks and clean the machine before you operate it.

Ether/cold start  uid is  ammable. Do not smoke

when using ether/cold start  uid. Always follow the

instructions on the can and in the manufacturer’s

operator’s manual(s) for your mower. Do not use ether/

cold start  uid if the engine is equipped with a glow plug

or other type of preheater.

clean parts. Do not use gasoline, diesel fuel or other

 ammable  uids.

Store all  ammable  uids and materials away from your

machine and work area.

Know where  re extinguishers are kept—how

they operate—and what type of  re they are for.

Check readiness of  re extinguishers according to

manufacturer’s instructions. Make sure each tractor is

equipped with a  re extinguisher.

Remove

Debris Daily or

As Needed

No Smoking

and No Open

Flames

Follow A Safety Program

Be Alert!

Know where to get assistance. Know how to use a  rst

aid kit and  re extinguisher/ re suppression system.

Be Aware!

Take advantage of training programs offered.

Be Careful!

Human error is caused by many factors: carelessness,

fatigue, overload, preoccupation, unfamiliarity of operator

with the machine, drugs, and alcohol to name a few.

Damage to the tractor or mower can be  xed in a short

period of time, but injury, or death, has a lasting effect.

For your safety and the safety of others, encourage your

fellow workers to act safely.

For Safe Operation

You must be a quali ed and authorized operator for

proper operation of your machine. You must clearly

understand the written instructions supplied by the

manufacturer, be trained—including actual operation of

the mower—and know the safety rules and regulations

for the worksite. It is a good safety practice to point

out and explain safety signs and practices and ensure

others understand the importance of following these

instructions.

WARNING! Drugs and alcohol affect an operator’s

alertness and coordination and the operator’s ability

to safely operate the equipment. Never use drugs or

alcohol while operating the mowing equipment.

Never knowingly allow anyone to operate this

machine when their alertness or coordination is

impaired. An operator taking prescription or over-the-

counter medication must consult a medical professional

regarding any side effects of the medication that would

hinder their ability to safely operate this equipment.

Never Use Drugs

or Alcohol While

Operating

Follow A Safety Program

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).

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

terrain conditions. Explain the practices to those

users and operators who cannot read.

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.

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.

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.

Mantenimiento de neumáticos y ruedas

Revise los neumáticos y las ruedas a diario porque la

estabilidad del tractor y la cortadora de césped puede

verse signi cativamente afectada por la presión de los

neumáticos o daños en los neumáticos o en las ruedas.

Revise los neumáticos para veri car:

— La presión correcta.

— Cortes y protuberancias.

— Clavos u otras pinchaduras.

— Desgaste desparejo o excesivo.

— Estado de los vástagos y tapas de las válvulas.

Revise las ruedas para veri car:

— Daños en las llantas.

— Tuercas o pernos faltantes o  ojos.

— Desalineación.

Todos los servicios de neumáticos deben ser realizados

por un centro de servicios para neumáticos cuali cado

o por una persona de servicio autorizada debidamente

capacitada en los procedimientos y el uso del equipo de

seguridad destinado a los servicios de neumáticos.

Revise los

neumáticos y las

ruedas en busca

de daños

Mantenga la

presión correcta en

los neumáticos

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

Palabras ﬁ nales para el usuario

Acaba de terminar de leer el Manual de la cortadora de

INTRODUCTION

2-1 DESCRIPTION

The HDTH cutters (Figure 2-1) are grooming mowers intended for cutting lawns, golf courses, athletic fields, or any

maintained area where a clean, uniform finish is desired. Uplift blades form a suction during operation to lift the grass

before cutting it. The caster wheel arrangement along with the floating lift linkage and optional front roller, all work

together to give an even cut and minimize scalping.

Power from the tractor is transmitted through a telescoping driveline to the gearbox. It is then passed to the spindle

housings by a single, B-section, Aramid Cord reinforced belt. Drivetrain protection is provided by belt slippage.

BUSH HOG HDTH SERIES FINISH MOWER

OPERATION INSTRUCTIONS

Bush Hog HDTH Finish Mowers are manufactured with quality materials by skilled workers. These mowers are

grooming mowers intended for cutting lawns, golf courses, athletic fields or any other maintained areas where a

clean, uniform finish is desired. The mower is equipped with protective deflectors to prevent objects from being

thrown from the mower by the blades. All deflectors and shielding equipped on this unit must be maintained in

good working operational condition.

It is the operator’s responsibility to be knowledgeable of all potential operating hazards and to take every reason-

able precaution to ensure oneself, others, animals and property are not injured or damaged by the mower, tractor

or a thrown object. Do not operate the mower if passersby, pets, livestock or property are within 300 feet of the

unit unless:

• ALL THROWN OBJECT SHIELDING, Including deflectors, Chain Guards (If equipped), Steel Guards and

Side Skirts are in place and in good condition while mowing.

• Mower is adjusted to be parallel to ground without exposing blades.

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

• PASSERSBY are inside an enclosed vehicle.

This section of this manual is designed to familiarize, instruct and educate safe and proper mower use to the op-

erator. Pictures contained in this section are intended a visual aid to assist in explaining the operation of the

mower. Some pictures may show shields removed for clarity purposes. NEVER OPERATE this implement without

all shields in place and in good operational condition. The operator must be familiar with the mower and tractor

operation and all associated safety practices before operating the mower and tractor. Proper operation of the

mower, as detailed in the manual will help ensure years of safe and satisfactory use of the mower.

To avoid mower damage, re-torture all bolts after the first 10 hours of operation.

OPERATION

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 re-

moved 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

Tractor Horsepower

The power required to operate a mower is determined by the tractor PTO horsepower. Operating the mower with

a tractor that does not have adequate power may damage the tractor engine. Exceeding recommended maximum

horsepower may cause mower damage by overpowering the unit in heavy cutting conditions.

Tractor 3-Point Lift

The tractor 3-point hitch must be rated to lift at least 954 lbs when attaching a HDTH7.

The mower is designed to be mounted on tractors with a CAT I or Cat II Standard and Quick Attach Hitch. Refer

to the tractor operator’s manual for the category of the tractor being used.

If the hitch does not conform to ASAE CAT I or CAT II dimensions or CAT lor CAT II Quick Attach Dimensions the

mower may not fit or raise properly. Consult an authorized dealer for possible modification procedures to mount

non-conforming hitches.

Use the correct hitch pins for the hitch category being used.

CAT I Standard Hitch, 7/8” lower and 3/4” upper diameter hitch pins. (Refer to Figures 3-3 & 3-5).

CAT l Quick Attach Hitch, 1-7/16” Lower and 1-1/4” upper hitch pins diameter. (Refer to Figures 3-4 &

3-5).

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.

OPERATION

Power Take Off (PTO)

NOTE: These mowers are designed for 540 RPM (PTO) speeds only.

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 1-3/8” diameter shaft and those operating at 1000 RPM will

have a 20-spline 1-3/4” diameter or 21-spline 1-3/8” diameter shaft. Note: 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_ARPM.

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 ex-

cessive 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)

Tire Spacing (Figure 4-1)

Tractor tires should be set a minimum of 60”

(1.524 Centimeters) apart. Measured from inside

of the tire to inside of the tire.

Refer to the tractor Operator’s Manual or consult

an authorized dealer for instructions to change

tractor tire spacing.

OPERATION

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 completely

stopped. (SG-12)

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 respon-

sible 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)

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. (SG-13)

CONNECTING THE MOWER TO THE TRACTOR

Use extreme caution when connecting the mower to the tractor. The mower should be securely resting at ground

level or setting on blocks. Keep hands and feet from under the mower deck and clear of pinch points between

the tractor hitch arms and mower pins. OPS-R-0001

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

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

Tractor hitches. (S3PT-15)

HDTH 7 Finish Mower 06/19

Operation Section 4-8

OPERATION

Connecting the Mower (Figure 4-2)

1. Make sure the tractor is equipped with the correct

PTO shaft. Change shafts if needed.

2. Shorten or remove the tractor drawbar to avoid in-

terference when raising and lowering the mower.

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

tractor to the mower with the 3-point lift arms posi-

tioned at the same height and to the outside of the

mower hitch pins. Note: Set the 3-point lift control to

“Position Control” so that the lift arms maintain a

constant height when attaching the mower. See the

tractor Operator’s Manual for correct settings when

attaching 3-point equipment.

4. Turn off the tractor engine, set the parking brake,

place the tractor in park, and dismount.

5. One lift arm at a time, position the tractor lift arms

DRIVELINE ATTACHMENT (Figure4-4)

The driveline yoke and tractor PTO shaft must be dirt free

and greased for attachment. Connect the driveline yoke

with the Push Pin to the gearbox input shaft of the mower.

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, re-

lease 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 en-

sure a secure attachment.

OPS R 0003_A

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

ing 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.

Operation Section 4-9

OPERATION

Driveline Length Modification

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 hous-

ing 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.

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 8-1/2”

must be maintained.

Bottoming Out Check Procedure (Figure 4-5)

● Disconnect Driveline from the tractor and slide the pro-

files together untill fully compressed.

●Place mark on the inner shield 1/8” from the end of the

outer shield.

●Reattach the driveline to the tractor PTO shaft.

●Raise the mower from the lowest to the highest posi-

tion 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.

NOTE: When raising the mower, clearence must be

maintained between driveline and mower deck. If nec-

essary set stop on 3Pt. lift control lever to limit the lift

height of the mower.

Shorten the Driveline Profiles as follows

(Figure 4-6)

●Remove Driveline from tractor PTO shaft.

●Position the mower to the point with the shortest dis-

tance between the tractor PTO shaft and the cutter

gearbox. Shut down the tractor and securely block the

mower in this position.

●Pull driveline apart and reattach yoke to the PTO Shaft.

●Hold the driveline sections parallel to one another and

measure 1” back from the yoke of each shaft and place

a mark on the opposite section. Cut this length with a

saw,

●Round off all sharp edges and debur.

●Throughly grease the reinstall the driveline.

● Recheck for propern operation.

OPERATION

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)

Cutting Height Adjustment (Figure 4-7 & Table 4-1)

The mower comes with four 1” spacers and one 1/2” spacer attached to each caster assembly. The height adjustment is from

1-1/2” to 6” cutting height in 1/2” increments.

1. Raise the mower off the ground using the tractor 3-point lift allowing the Caster Wheels to clear the ground enough for removal.

SECURELY BLOCK THE MOWER IN THIS POSITION.

The mower can fall from hydraulic system failure. To avoid serious injury or death, securely

support the mower before working close to or underneath.

2. Remove the retaining pin securing caster wheel in pivot tube and remove he caster wheel and spacers.

3. Place spacers on the pivot shaft of the caster wheel that will allow you to achieve the desired cutting height, See (Table 4-1).

4. Reinstall caster wheel in pivot tube with height adjusting spacers on the bottom. Place the un used spacers on the pivot shaft

on top and reinstall the retaining pin.

5. Repeat these step for all caster wheels making sure all are adjusted to the same height.

DRIVING THE TRACTOR AND IMPLEMENT

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

tions 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

This Implement may be wider than the Tractor. Be careful when operating or transporting this

equipment to prevent the Implement from running into or striking sign posts, guard rails, concrete

abutments or other solid objects. Such an impact could cause the Implement and Tractor to pivot

violently resulting in loss of steering control, serious injury, or even death. Never allow the Imple-

ment to contact obstacles. (S3PT-12)

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 prop-

erly.

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 de-

termine 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 de-

termine 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

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 con-

trol lever is in the lowered position and the PTO is disen-

gaged before starting the tractor. OPS-U-0033

Brake and Differential Lock Setting

Make sure the tractor brakes are in good operating con-

dition. Tractor brakes can be set to operate independently

allowing single rear wheel braking action or locked to-

gether 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 turn-

ing. 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. OPSU- 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.

Raising the Mower

Using the tractor 3-point hitch control lever, raise the

mower off the ground about 6”, or just high enough to

clear any ground obstacles. When raising the mower,

make sure all connection points are securely attached

and at least 1” clearance is maintained between the dri-

veline 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_C

Operating the Tractor and Mower

Start off operating 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, cross-

ing 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.

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 maxi-

mum depth until the assembly becomes solid (driveline

is at its extreme shortest length). This type of abusive op-

eration 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.

HDTH 7 Finish Mower 06/19

Operation Section 4-17

OPERATION

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

damaged to over collapse of the driveline may occur.

When crossing such terrain, the implement should be fully

lowered for a lower center of gravity and added stability.

OPS-R-0021

Inclines and ditches should be approached along a line

which is at an angle as shown. This type of path will re-

duce 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, se-

lect an alternate crossing path.

When operating the tractor and mower across slopes and

inclines, through ditches, and other uneven terrain condi-

tions, 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 dam-

age.

Ground contact also produces a severe shock load on the

mower drive and to the mower blades resulting in possible

damage and premature wear.

HDTH 7 Finish Mower 06/19

Operation Section 4-18

OPERATION

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 oper-

ating 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)

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)

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 ob-

jects 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 imple-

ment 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 im-

mediately. 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

HDTH 7 Finish Mower 06/19

Operation Section 4-19

OPERATION

Bystanders/Passersby Precautions

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.

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

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 uni-

form).

(SRM 01)

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, in-

cluding clearance or for turning. Raising the Mower deck exposes the Cutting

Blades which creates a potentially serious hazard and could cause serious in-

jury 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 seri-

ous injury or even death. Stay away until all motion has stopped and the decks

are securely blocked up. (SGM-09)

HDTH 7 Finish Mower 06/19

Operation Section 4-20

OPERATION

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 en-

gine 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 Im-

plement 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)

Operating the Mower

The mower is designed to cut grass and light weeds. Travel at a speed that allows the mower sufficient time to cut

through the vegetation and maintain the PTO operating speed 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. Re-

member, sharp blades produce cleaner cuts and use 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 reduced ground speed to ensure control is maintained of the tractor and mower.

OPS R 0026_I

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)

HDTH 7 Finish Mower 06/19

Operation Section 4-21

OPERATION

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 accessible 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 burned areas.

● Ensure belts are properly adjusted to prevent excessive slippage and over heating.

● Never allow clippings or debris to collect near drivelines, under shielding around belts and pulleys, and gearboxes.

● Periodically shut down the Tractor and Mower and clean clippings and collected debris from the mower deck.

(SGM 12)

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)

Stay alert and watch for trees, low hanging limbs, power lines, and other overhead obstacles and

solid ground objects while you are operating. Use care to avoid hitting these items.

When mowing across uneven areas such as road shoulders, ditch edges, and other uneven ter-

rain, position mower so that one support wheel is near the highest point to prevent blades from

cutting into gravel or dirt which can cause rapid blade wear and extremely severe shock loads on the drivetrain resulting

in rapid wear or damage to these components. Blades contacting the ground may cause objects to be thrown out from

under the mower deck. Always avoid operating the mower at a height or position which may cause the blades to

contact the ground. Cutting into the berm or edge of the ditch will cause abnormal and accelerated blade wear and

possible blade component failure.

Shutting Down the Mower

To shut down the mower operation:

1. Bring the tractor to a complete stop on a level surface.

2. Decrease the engine speed (RPM) to idle.

3. Place the transmission in park or neutral and apply the parking brake.

4. Disengage the PTO and wait for the blades to stop turning. (Do Not Disengage the PTO at a High RPM unless it

is an emergency situation).

5. Lower the mower to the ground.

6. Shut down the tractor, remove key and wait for all motion to come to a complete stop before exiting tractor.

DISCONNECTING THE MOWER FROM THE TRACTOR

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)

Before disconnecting the mower, the PTO must be disen-

gaged 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.

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 pro-

cedures, the possibility of accidents while moving between locations can be substantially minimized. OPS-U- 0017

Never tow the implement at speeds greater than 20 MPH

(32 kph). OPS-U- 0018

Transporting on Public Roadways

Extreme caution should be used when transporting the tractor and mower 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.

Before operating your Finishing Mower, 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.

Lubrication

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

The illustrations below shows lubrication points. The chart gives the frequency of lubrication in

hours, based on normal operating conditions. Severe or unusual conditions may require more fre-

quent lubrication. MntP-R-0381.

Use Multi-Purpose Gear Oil EP80W-90 when required in Gearbox. Use N.L.G.I.#2 Lithium grease

for all locations requiring application using grease gun. Be sure to clean the fitting thoroughly

before using grease gun. Daily lubrication of the wing driveline slip joint is necessary. Failure to

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

MAINTENANCE

Gearbox Maintenance

The first oil change must be done after 50 hours of working time and then after 400-500 hours of work. Keep in mind

that intense and continuous working conditions will necessitate more frequent oil changes and periodic checks. It is a

good practice to check the oil level every 50-60 hours of work. When changing the oil, detach the mower and driveline

entirely from the tractor. Remove the driveline from the mower. However, depending on the situation and the operator’s

experience, the tools and equipment available, and the area where the oil change is done (in the shop, in the field,

etc.), other procedures may be used provided that the operator is always fully aware of the hazards connected with

this operation.

Never work under the Implement, the framework, or any lifted component un-

less the Implement is securely supported or blocked up to prevent sudden or

inadvertent falling which could cause serious injury or even death. (SG-14)

To change the oil, keeping in mind the preceding safety recommendations, place the mower in a vertical position

(Figure 5-1), or inclined enough so that once the Vent Plug and the 3/8” Check Plug (Figure 5-2) are removed the oil

can drain out of the Check Plug opening. Once the used oil has been completely drained, place the mower back in a

level position and add oil in the Vent Plug opening until it starts to come out of the Check Plug opening. Allow enough

time for the new oil to seep down into the lower housing through the bearings and fill as needed. Put the Vent Plug

and the 3/8” Check Plug back in place when properly filled. For a full oil change, approx. 0.5 liters use EP80W-90

Gear Oil.

The Vent Plug on the housing is for filling, and 3/8” Check Plug on the side is for checking the level (Figure 5-2). To

check the level, simply unscrew the 3/8” Check Plug and see if the oil reaches the lower part of the opening. To fill oil,

remove the Vent Plug and add oil until it starts to come out of the opening for the 3/8” Check Plug. Re-install the Vent

Plug and the 3/8” Check Plug.

DRIVELINE MAINTENANCE

The Driveline should be serviced every 8 hours of operation. Refer to (Figure 5-3)

1. Disconnect the driveline from the Tractor PTO and from the Gearbox input shaft.

2. Pull the driveline halves apart.

3. Release the Shield Cones from the shield tubes by pressing down on the retaining tabs located under the access

holes on the back of the shield cones (there are 3 tabs on each cone) and separate the shield tubes from the

cones exposing the driveshaft inner and outer tubes.

4. Thoroughly clean old grease from the tubes and apply a thin coat of multi-purpose grease to the outside of the

inner tube (male) section.

5. Re-assemble the shielding on the two halves and then re-assemble the driveline halves.

6. Put 1 or 2 shots of grease in the lube points for the shield bearing locations.

7. Grease the Cross Bearing in the fittings on both ends of the shaft.

8. Apply a lite coat of oil to the Slide Collar (Tractor End) and the Push Pin (Implement End) to prevent rust from

forming making their functions difficult.

9. Re-attach the Driveline to the Gearbox Input Shaft and then to the Tractor PTO shaft.

10. Pull on each end of the shaft to make sure the shielding is secure to the Driveline and the driveline is securely at-

tached to the PTO Shaft and the Input Shaft of the Gearbox.

BLADE SPINDLE and BELT TENSION IDLER ARM

LUBRICATION & MAINTENANCE

The area beneath the shielding must be cleaned of debris such as grass clippings and twigs to prevent buildup, causing

friction on belt and pulleys. Clean any lubricant accumulation occuring during the lubrication procedures.

Check drive pulleys and idler pulleys for excessive wear or damage. Replace if needed.

Check Belt Tensioner Idler Arm for excessive wear / looseness and freedom of movement.

Blade spindles (Figure 5-4) must be greased with 5 shots of grease every 10 hrs. Access lubrication fittings through

holes in top of the shielding above the Spindle Assembly. Occasionally grease the spindle until a small amount of

grease purges from the relief hole (Figure 5-5), located at the base of the spindle housing under the sheave. The

shielding will need to be removed in order to see the relief hole. Clean off any excess grease. The Belt Tension Idler

Arm should be greased each time the blade spindles are greased with 3 shots of grease.

NOTE: Do not over lube as excess grease may get on belt drive and cause belt slippage.

MAINTENANCE

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 removed by sharpen-

ing.

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

steel. WILL-FIT BLADES MAY NOT MEET SPECIFICATIONS AND MAY FAIL CATA-

STROPHICALLY AND CAUSE BODILY INJURY OR DEATH.

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

WELD, OR WELD HARDFACING ON BLADES SINCE THIS WILL LIKELY CRACK OR OTH-

ERWISE DAMAGE THE BLADE WITH SUBSEQUENT FAILURE AND POSSIBLY CAUSE

SERIOUS INJURY FROM THROWN BLADES. (SGM-10)

Inspect Blades daily for abnormal wear. If Blades have a notch worn into the leading edge at

the lower bend more than a 1/2” DEEP (due to running in gravel and/or contact with the

ground), REPLACE BLADES ON THAT CARRIER IMMEDIATELY. Failure to replace such

abnormally worn blades may lead to catastrophic failure of the blade and ejection of the bro-

ken part with tremendous force which may cause bodily injury or death!

NOTE: Replace Blades after no more than 1/2" notch wear!

BLADE SHARPENING

Always sharpen both cutting edges of each blade at the same time, the same amount, to maintain balance. Follow

original sharpening pattern as shown. Do not sharpen blade to a razor edge, but leave a 1/32” blunt edge. Do not

sharpen back side of blade. Figure Mnt-R-0303.

When sharpening blades, grind each blade the same amount to maintain balance. Unbalanced blades will cause

excessive vibration which can damage gear box bearings. Vibration may also cause structural cracks in cutter

housing.

Never work under equipment supported by a hydraulic device because it may drop if the

control is actuated (even with the engine stopped) or in the event of hose failure, etc. Always

use a secure support for equipment which must be serviced while in the raised position.

MAINTENANCE

BLADE REMOVAL

Never work under the implement, or any lifted component unless the imple-

ment is securely supported or blocked to prevent sudden or inadvertant falling

which can cause serious injury or death.

1. Raise cutter using tractor hydraulics and SECURELY BLOCK INTO POSITION.

2. Set parking brake, turn off tractor and remove key.

3. Remove center bolt securing blade and blade bar to spindle. Blade and bar will come off as a unit. Blade bar can

then be removed from the blade. Be sure the blade washer remains in place. If it does come off retain for reinsta-

lation before reinstalling the blade bar.

(Figure 5-6)

BLADE INSTALLATION (Figure 5-6)

1 Install new blade(s) on the blade bar as shown in (Figure 5-6). Be sure that blades are installed with offset in proper

direction. Tighten retaining bolts to 65 ft./lbs.

2. Place th cup washer on the center bolt with the curved side to the bolt head see Detail “A” below..

3. Be sure the blade washer is in place and place the blade bar with blades on the shaft. Insure the offset of the blades

are down.

BELT REMOVAL, REPLACEMENT and ADJUSTMENT

The mower drive belt should be checked after every 40 hours of use for unusual wear, cracking, fraying or pieces

missing. Belts that are too loose or too tight will not give good service and will not last as long. Replacing and /or ad-

justing belt should be performed using maximum cauton. Protective shielding will need to be removed to replace the

belt or adjust the belt tension.

Belt Removal and Replacement (Figure 5-7)

Note: Use only Genuine Bush Hog Belts for replacement. Will Fit (after market belts) may not meet the re-

quirements for usage in belt life and mower performance.

1. Park the mower on a firm level surface. Lower the implement to the ground. Shut the tractor down, set parking

brake and dismount.

2. Disconnect the driveline from the input shaft of the gearbox on the mower.

3. Remove the two outer belt shields and the center shield, retain the fasteners for re-installation.

4. Relieve the tension on the belt by loosening the two 3/8” hex nuts on the tensioner rod.

5. Remove the old belt.

6. Install the new belt referring to (Figure 5-7) for correct belt routing. There is also a decal on the mower deck you

may refer to showing the correct belt routing.

7. Refer to (Figure 5-8) Belt Adjustment for correct setting of belt tension.

Belt Ajustment (Figures 5-7 & 5-8)

Tension on the mower belt is achieved by tightening the

3/8” hex nut against the tensioner bracket until the proper

spring length is reached. This length is measured from

the center of the spring attaching hole of the tensioner

rod to the center of the mounting pin on the idler arm. The

spring length should be set to between 7” to 7½” as

shown in (Figure 5-8).

Loosen the outer 3/8” hex nut on the tensioner rod and

then turn the hex nut aginst the tensioner bracket to

lengthen or shorten the spring length. When the proper

length is set, turn the outer hex nut to contact adjusting

nut to lock the position.

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.

Los cuidados que brinde a su Implemento Bush Hog determinarán en gran medida su satisfacción con el

desempeño 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

corresponden a la perspectiva en el sentido del desplazamiento hacia delante con el implemento correctamente

sujetado al tractor.

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

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 Bush Hog. 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 Bush Hog para ahorrar dinero y maximizar la

seguridad.

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