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 Operators
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.

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

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.

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.
Follow
All Mower
Safety Rules
14
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:

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.

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 (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.

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.

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.

antes de reanudar el corte.
No haga funcionar una cortadora que vibra en exceso o
produce ruidos anormales.
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
14
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

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

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
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.

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

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
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

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

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

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
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.

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.

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

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
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
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

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

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
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
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
© 2011 Alamo Group Inc.
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
© 2011 Alamo Group Inc.
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
© 2011 Alamo Group Inc.
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

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
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

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.

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.

(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

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.

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

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
to pass. Do not exceed the legal speed limit set in
your country for agricultural tractors. Always stay
alert when transporting the tractor and implement
on public roads. Use caution and reduce speed if
other vehicles or pedestrians are in the area. OPS-

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

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!

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

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.

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.

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.

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.
La informacion y material mecionado en la informacion anterior junto con el Manual de Operador puede asistir
en cumplir con los requisitos de OSHA para el entrenamiento anual del Operador.
REQUISITOS DE ENTRENAMIENTO DEL OSHA

Instrucciones del operador. A la hora de la asignación inicial y por lo menos anualmente después de eso, el
empleador mandará a cada empleado quien opera un tractor agricola o implemento en las practicas de
operación segura y el mantenimiento de el equipo con el cual el empleado esté, o estará implicado y de
cualquier otras prácticas dictados por el ambiente laboral.
Al propietario/operador/distribuidor
Este Manual del Operador es una parte esencial de la operación segura de esta máquina y se debe mantener con
la unidad siempre. El implemento incluye un porta manual donde se puede guardar el manual de manera
adecuada. Si el manual se extravía o se daña, puede solicitar otra copia sin cargo a un distribuidor autorizado de
Rhino o descargarlo del sitio web de Rhino (www.servis-rhino.com).
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 Rhino 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 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.
