Avoid Injury From Fire And Explosion
Set the parking brake, shut the mower and tractor
engine down and remove the key while  lling the fuel
tank. Use extra caution when fueling a hot engine.
Never smoke while fueling. Avoid sparks by grounding
the fuel nozzle against the  ller neck.
The fumes in an empty fuel tank are explosive. Never
weld or cut on fuel lines, tanks or containers.
Remove all trash or mowing debris from the machine
daily or as needed. Keep debris away from engine,
exhaust, slip clutches and other heat sources. Use
spark arrestors, as appropriate, on the engine exhaust
system. Make sure oily rags or other  ammable material
are not stored on the machine.
Check for fuel, oil or hydraulic  uid leaks. Repair the
leaks and clean the machine before you operate it.
Ether/cold start  uid is  ammable. Do not smoke
when using ether/cold start  uid. Always follow the
instructions on the can and in the manufacturer’s
operator’s manual(s) for your mower. Do not use ether/
cold start  uid if the engine is equipped with a glow plug
or other type of preheater.

Follow A Safety Program
Be Alert!
Know where to get assistance. Know how to use a  rst
aid kit and  re extinguisher/ re suppression system.
Be Aware!
Take advantage of training programs offered.
Be Careful!
Human error is caused by many factors: carelessness,
fatigue, overload, preoccupation, unfamiliarity of operator
with the machine, drugs, and alcohol to name a few.
Damage to the tractor or mower can be  xed in a short
period of time, but injury, or death, has a lasting effect.
For your safety and the safety of others, encourage your
fellow workers to act safely.
For Safe Operation
You must be a quali ed and authorized operator for
proper operation of your machine. You must clearly
understand the written instructions supplied by the
manufacturer, be trained—including actual operation of
the mower—and know the safety rules and regulations
for the worksite. It is a good safety practice to point
out and explain safety signs and practices and ensure
others understand the importance of following these
instructions.
WARNING! Drugs and alcohol affect an operator’s
alertness and coordination and the operator’s ability
to safely operate the equipment. Never use drugs or
alcohol while operating the mowing equipment.
Never knowingly allow anyone to operate this
machine when their alertness or coordination is
impaired. An operator taking prescription or over-the-
counter medication must consult a medical professional
regarding any side effects of the medication that would
hinder their ability to safely operate this equipment.
Never Use Drugs
or Alcohol While
Operating
Follow A Safety Program
Know The Rules
Most employers have rules governing operation and
maintenance of equipment. Before you start work at a
new location, check with your supervisor or the safety
coordinator. Ask about the rules you will be expected
to obey.
The Occupational Safety and Health Administration
(OSHA) enforces federal laws within the United
States that apply to safe operation, application and
maintenance of equipment on a worksite. It is the
employer’s responsibility to comply with these laws.
An OSHA representative may periodically inspect a
worksite to see that these laws are being followed.
There may also be local or state/provincial laws or
international regulations that apply to this equipment
and its use, along with speci c worksite or employer
rules. It is important that you know and comply with
all applicable laws and rules, including those requiring
operator training and certi cation.
These are some of the rules you must work by:
A ROPS and seat belt-equipped tractor is a federal
government (OSHA) requirement for operator
protection during mowing operations. An enclosed
cab provides additional operator protection from
thrown objects. Check your mower operator's manual
to see if a tractor cab is also required.
Wear and check that others are wearing proper
clothing and personal protective equipment.
Inspect your machine and attachments before each use
as speci ed by the manufacturer and your employer.
Know the limitations and operating characteristics of
your mowing equipment. Do not misuse it.
Have all provided shields and guards properly
installed before operating the machine.
Never modify or remove any part of the machine
(except for service—then make sure it is replaced).

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:

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:
Review tractor and mower operator’s manuals for
operating safety practices on slopes and uneven

Hydraulic System Hazards
The hydraulic system is under pressure whenever the
engine is operating and may hold pressure even after the
engine is shut off. Cycle all hydraulic controls including
the auxiliary hydraulic control after the engine is shut
down. Relieve trapped pressure in the lines after the
attachments are shut down and resting on the ground.
During inspection of the hydraulic system:
Wait for  uid to cool before disconnecting the lines.
Hot hydraulic  uid can cause SEVERE BURNS.
Do not use your hand to check for leaks. Instead,
use a piece of cardboard or paper to search for leaks.
Wear appropriate eye protection. Hydraulic  uid can
cause permanent eye injury.
WARNING! Hydraulic  uid under pressure can penetrate
the skin or eyes and cause serious injury, blindness or
death. Fluid leaks under pressure may not be visible.
Use a piece of cardboard or wood to fi nd leaks, not
your hand. Wear a face shield or safety goggles for
eye protection. If  uid is injected into the skin, it must
be removed within a few hours by medical personnel
familiar with this type of injury.
When venting or  lling the hydraulic system, loosen the
ller cap slowly and remove it gradually.
Never reset any relief valve in the hydraulic system to a
pressure higher than recommended by the manufacturer.

Avoid Explosion
WARNING! Avoid possible serious injury from
explosion. Lead-acid batteries produce extremely
explosive gases especially when being charged. Keep
arcs, sparks, fl ames and lighted tobacco away.
Do not smoke near batteries.
Keep arcs, sparks and open  ames away from
batteries.
Provide adequate ventilation.
Never check the battery by placing a metal object
across the battery posts — the resulting spark could
cause an explosion.
WARNING! Avoid possible serious injury from battery
explosion. Do not charge a battery or boost start the
engine if the battery is frozen. Warm to 60°F (15.5°C)
or the battery may explode and could cause serious
injury.
Safety rules during battery boost starting:
Follow the instructions for proper “battery boost
starting” as speci ed in the manufacturer’s manual.
Be sure the machines are not touching.
Observe the polarity of the batteries and connections.
Make the  nal cable connection to the engine or the
furthest ground point away from the battery. Never
make the  nal connection at the starter or dead
battery—sparks may ignite the explosive gases
present at the battery.
When disconnecting cables after jump starting,
remove the cables in reverse order of connection
(e.g.,  nal connection  rst).

Tire And Wheel Maintenance
Check your tires and wheels daily because the stability
of the tractor and mower can be dramatically affected
by tire pressure or damage to tires or wheels.
Check tires for:
— Correct pressure.
Cuts and bulges.
Nails or other punctures.
Uneven or excessive wear.
Condition of valve stems and caps.
Check wheels for:
Damage to the rims.
Missing or loose lug nuts or bolts.
— Misalignment.
All tire service should be performed by a quali ed tire
service center or by an authorized service person who
has been properly trained in the procedures and use of
safety equipment designed for tire servicing.

Tire And Wheel Maintenance (continued)
WARNING! The types of wheels and tires usually
found on this equipment require special care when
servicing to prevent death or serious injury.
Do not in ate the tires above the recommended
pressure. Be sure to replace tire ballast if equipped. See
manufacturer’s speci cations for ballast requirements.
Keep wheel lug nuts tightened to manufacturer’s
recommendations.
A rise in tire pressure during operation is normal, and
should NOT be reduced.
Never rein ate a tire that has been run  at or seriously
underin ated without removing the tire from the wheel.
Have the tire and wheel closely inspected for damage
before remounting.
When adding air to a tire, do so from a distance. Use
a long hose with self-attaching chuck. Always stand
behind tread when adjusting tire pressure.
Do not in ate tires with  ammable gases or from
systems using an alcohol injector.
Never cut or weld on a wheel with an in ated
tire mounted on it. This could cause explosive
decompression.
Check that the tire size and wheel are correctly matched.
When replacing the tires, ensure the tires are of the
appropriate rating speci ed by the manufacturer.
Tires should not be operated at speeds higher than their
rated speed. Most agricultural tires are rated for 20mph
maximum speed.

Complete Service And Repairs Before Machine
Is Released
Tighten all bolts,  ttings, and connections to torques
speci ed by the manufacturer.
Install all guards, covers, and shields after servicing.
Replace or repair any damaged parts. Re ll and
recharge pressure systems only with manufacturer
approved or recommended  uids.
Start the engine and check for leaks. (See page 23,
Hydraulic System Hazards.) Operate all controls
to make sure the tractor and mower are functioning
properly. Test the machine if necessary. After testing,
shut down and check the work you performed. Are
there any missing cotter pins, washers, locknuts, etc.?
Recheck all  uid levels before releasing the equipment
for operation.
All parts should be inspected during repair and replaced
if worn, cracked or damaged. Excessively worn or
damaged parts can fail and cause injury or death.
Replace any damaged or illegible safety signs.
Mower Blade Maintenance
Do not take chances using damaged or bent blades.
The mower manufacturers from the Association
of Equipment Manufacturers (AEM) and the Farm
Equipment Manufacturers Association (FEMA) advocate
that you DO NOT reuse, straighten, hard face or weld
mower blades. Death or serious injury could result if a
broken blade is thrown from a mower.

Mower Blade Maintenance (continued)
How are mower blades made?
Mower blades are made of high strength alloy spring
steel. They are hot-forged and shaped to meet the
manufacturer’s individual speci cations, then heat
treated and tempered to a high strength, ductile state
to reduce the possibility of breaking while mowing.
Blades are tested to ensure they meet strength,
hardness, and ductility standards. If a blade fails to
meet any of these speci cations, it will not be used
on the mower.
What happens when a mower blade bends?
It takes a great amount of impact force to bend
the blade. This impact force often results in the
blades being gouged or chipped. After a blade
is damaged by a gouge or chip a blade failure is
much more likely to occur. When a blade is severely
bent, a microscopic crack may be created in the
blade. Straightening the blade does not remove or
repair this crack, but may cause additional cracks.
Additional stresses during mowing operations can
result in an unexpected blade failure.
Avoid bending blades. Help prevent mower blades
from bending or cracking by avoiding contact with
solid objects. Mower blades are intended to cut
grass, shrubs, woody vegetation, and small trees and
limbs. They are not intended to contact solid objects
such as rocks, concrete, or steel posts. Inspect the
area prior to mowing. Remove or clearly mark any
solid objects and mow around them.
Replace damaged blades! Inspect the mower blade(s)
daily or after hitting any solid object. If a mower blade
becomes damaged (bent, gouged, cracked) or worn
more than 25 percent of the original size, it should
be removed and replaced with a new blade. Always
use the original manufacturer’s blades. Aftermarket
brand blades may not meet the mower manufacturer’s
strength, hardness and ductility requirements.
Do not take chances mowing with damaged or
bent blades. Using a damaged or straightened
mower blade can result in the blade breaking and
being thrown into the operator or a bystander causing
death or serious injury. The price of a new blade is
small compared to the potential for the serious injury
that could result from a bent or broken blade being
thrown from the mower.

Objetos arrojados por la cortadora de césped
Dependiendo del propósito previsto, las cortadoras
están diseñadas para cortar hierba, maleza, broza y
cultivos. Las hojas de la cortadora están diseñadas y
probadas para uso intensivo. Las hojas de la cortadora,
sin embargo, no están diseñadas para entrar en contacto
con objetos sólidos como rocas, cemento o metales. Un
impacto de este tipo puede arrojar objetos rotos hasta
300 pies (92 m) de distancia. Nunca debe haber personas
ajenas a menos de 300 pies (92 m) de una cortadora
giratoria en funcionamiento o a menos de 100 pies (30 m)
de una cortadora de disco correctamente equipada.
Hojas giratorias –
Manténgase
No ponga en
funcionamiento una
cortadora de césped
dañada
Operación con seguridad
Los escudos de la cortadora están diseñados para reducir
el riesgo de objetos arrojados y se deben mantener
correctamente y en su lugar durante las operaciones de
corte.
El riesgo de lesiones graves o muerte puede reducirse
signi cativamente si se siguen estas reglas. Si no se
siguen todas estas reglas de seguridad, la operación
de corte debe detenerse en caso de que alguna
persona ingrese dentro del límite de seguridad
correspondiente a cada tipo de cortadora.
Primero — Inspeccione la zona antes de cortar y retire las
piedras, ramas, alambres, cables, metales, vidrios y otros
objetos sólidos antes de hacer funcionar la máquina. Los
objetos que no puedan retirarse deben marcarse con
claridad y ser evitados con cuidado por el operador.
En áreas sin cultivos con hierba y maleza de altura
su ciente como para ocultar objetos que podrían ser
golpeados por las hojas, inspeccione la zona y retire o
marque los residuos u obstáculos grandes.
Realice el corte de la zona a una altura intermedia.
Inspeccione la zona atentamente y retire o marque
cualquier residuo u obstáculo restante. Corte nuevamente
a la altura  nal deseada.
Segundo — Los escudos para objetos arrojados por la
cortadora deben usarse cuando se opera cerca de caminos,
parques, zonas pobladas u otras zonas donde objetos
arrojados podrían lesionar a personas ajenas o dañar la
propiedad. Siga el manual del operador del fabricante.
Tercero — Cruce en sentido diagonal cuando realiza
el corte a través de zanjas, depresiones marcadas y
hundimientos. Eleve la cortadora para evitar que las hojas
de la cortadora golpeen el suelo.
Siga todas
las reglas de
seguridad
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.

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

25
Mantenimiento de neumáticos y ruedas
(continuación)
¡ADVERTENCIA! Los tipos de ruedas y neumáticos
que generalmente se encuentran en estos equipos
requieren cuidados especiales al realizar servicios
para evitar lesiones graves o la muerte.
No in e los neumáticos por encima de la presión
recomendada. Asegúrese de volver a colocar el lastre
de los neumáticos si está instalado. Consulte las
especi caciones del fabricante para ver los requisitos
de lastre.
Mantenga las tuercas de las ruedas apretadas según las
recomendaciones del fabricante.
Es normal que la presión de los neumáticos aumente
durante el funcionamiento; NO se debe reducir.
Nunca vuelva a in ar un neumático que se ha desin ado
mucho o por completo sin retirar el neumático de la
rueda. Haga inspeccionar atentamente el neumático y la
rueda para detectar daños antes de volverlos a armar.
Al agregar aire a un neumático, hágalo desde cierta
distancia. Use una manguera larga con mandril de
auto jación. Siempre párese detrás de la trocha cuando
ajusta la presión de un neumático.
No in e neumáticos con gases in amables o con sistemas
que usan un inyector de alcohol.
Nunca corte o suelde una rueda con un neumático in ado
instalado en ella. Esto podría causar descompresión
explosiva.
Veri que que el tamaño del neumático y la rueda
coincidan correctamente.
Cuando reemplaza neumáticos, asegúrese de que sean de
la clasi cación adecuada especi cada por el fabricante.
Los neumáticos no deben funcionar a velocidades más
altas que las nominales. La mayoría de los neumáticos
para agricultura están clasi cados para una velocidad
máxima de 20 mph (32 km/h).
Evite la explosión
de los neumáticos
Realización de mantenimiento con seguridad
Servicio y reparaciones completas antes de
liberar la máquina
Apriete todos los pernos, accesorios y conexiones con las
torsiones especi cadas por el fabricante.
Instale todas las guardas, cubiertas y escudos después
de realizar los servicios. Reemplace o repare los que
estén dañados. Llene y recargue los sistemas a presión
sólo con los  uidos aprobados o recomendados por el
fabricante.
Arranque el motor y revise para detectar fugas. (Consulte
la página 23, Riesgos del sistema hidráulico.) Haga
funcionar todos los controles para asegurarse de que el
tractor y la cortadora de césped funcionan correctamente.
Pruebe la máquina si es necesario. Después de las
pruebas, apague y veri que el trabajo realizado. ¿Falta
algún pasador, arandela, tuerca de seguridad, etc.?
Vuelva a revisar todos los niveles de  uidos antes de
liberar la máquina para el funcionamiento.
Todas las piezas deben ser inspeccionadas durante la
reparación y deben reemplazarse si están gastadas,
rajadas o dañadas. Las piezas excesivamente gastadas o
dañadas pueden fallar y causar lesiones o la muerte.
Reemplace cualquier letrero dañado o ilegible.
Mantenimiento de las hojas de la cortadora
No corra riesgos usando hojas dañadas o dobladas. Los
fabricantes de cortadoras de césped de la Asociación
de Fabricantes de Equipos (Association of Equipment
Manufacturers, AEM) y la Asociación de Fabricantes de
Equipos para Agricultura (Farm Equipment Manufacturers
Association, FEMA) piden que las hojas de cortadoras
NO se reutilicen, enderecen, refuercen en su super cie o
suelden. Si una hoja rota es arrojada por una cortadora,
podrían producirse lesiones graves o la muerte.
Verifi que el trabajo
de servicio cuando
está completo
Realización de mantenimiento con seguridad
26
Realización de mantenimiento con seguridad
Mantenimiento de las hojas de la cortadora
(continuación)
¿Cómo están hechas las hojas de la cortadora
de césped? Están hechas acero para resortes de
aleación de alta resistencia. Se forjan en caliente y se
les da forma para cumplir con las especi caciones
individuales del fabricante; luego, se tratan y templan
a un estado dúctil, de alta resistencia para reducir la
posibilidad de rupturas durante el corte. Las hojas se
prueban para garantizar que cumplan con las normas
de resistencia, dureza y ductilidad. Si una hoja no
cumple con alguna de estas especi caciones, no se
utilizará en la cortadora de césped.
¿Qué sucede cuando se dobla una hoja de la
cortadora? Se necesita una gran fuerza de impacto
para doblar la hoja. Esta fuerza de impacto a menudo
resulta en que las hojas se agujerean o marcan. Una
vez que una hoja está dañada por un agujero o una
marca, es mucho más probable que ocurra una falla
de la hoja. Cuando una hoja está gravemente doblada,
puede crearse una rajadura microscópica en ella.
Enderezar la hoja no quita o repara esta rajadura, sino
que puede causar rajaduras adicionales.Tensiones
adicionales durante los trabajos de corte pueden
resultar en una falla imprevista de la hoja.
Evite doblar las hojas. Contribuya a prevenir que las
hojas de la cortadora se doblen o rajen evitando el
contacto con objetos sólidos. Las hojas de la cortadora
de césped están destinadas a cortar hierba, arbustos,
vegetación leñosa y árboles y ramas pequeños. No
están diseñadas para entrar en contacto con objetos
sólidos como roca, cemento o postes de acero.
Inspeccione la zona antes de usar la cortadora. Retire
o marque claramente los objetos sólidos y corte
alrededor de ellos.
Sustituya las hojas dañadas! Inspeccione las hojas
de la cortadora diariamente o después de golpear
algún objeto sólido. Si una hoja de la cortadora de
césped se daña (está doblada, agujereada, rajada) o
desgasta más del 25 por ciento del tamaño original,
debe retirarse y sustituirse con una nueva. Siempre use
las hojas originales del fabricante. Las hojas de marcas
no originales pueden no cumplir con los requisitos de
resistencia, dureza y ductilidad del fabricante de la
cortadora.
No corra riesgos usando hojas dañadas o dobladas.
El uso de una hoja de cortadora dañada o enderezada
puede resultar en la ruptura de la hoja y que la hoja
sea arrojada hacia el operador o una persona ajena
causando una lesión grave o la muerte. El precio
de una nueva hoja es bajo en comparación con la
posibilidad de una lesión grave que podría resultar de
una hoja doblada o rota arrojada por la cortadora
Palabras fi nales para el usuario
Acaba de terminar de leer el Manual de la cortadora de
césped industrial y para agricultura AEM. Es imposible

2-1 DESCRIPTION
The HDTH cutters (Figure 2-1) are grooming mowers intended for cutting lawns, golf courses, athletic fields, or any
maintained area where a clean, uniform finish is desired. Uplift blades form a suction during operation to lift the grass
before cutting it. The caster wheel arrangement along with the floating lift linkage and optional front roller, all work
together to give an even cut and minimize scalping.
Power from the tractor is transmitted through a telescoping driveline to the gearbox. It is then passed to the spindle
housings by a single, B-section, Aramid Cord reinforced belt. Drivetrain protection is provided by belt slippage.

Tractor Safety Devices
If transporting or operating the tractor and implement near a public roadway, the tractor must be equipped with
proper warning lighting and a Slow Moving Vehicle (SMV) emblem which are clearly visible from the rear of the
unit. Lights and a SMV emblem must be equipped directly on implements if the visibility of the tractor warning
signals are obscured.
Maintain all manufacturer equipped safety shields and guards. Always replace shields and guards that were re-
moved for access to connect, service, or repair the tractor or implement. Never operate the tractor PTO with the
PTO master shield missing or in the raised position. OPS-U- 0004
Tractor Horsepower
The power required to operate a mower is determined by the tractor PTO horsepower. Operating the mower with
a tractor that does not have adequate power may damage the tractor engine. Exceeding recommended maximum
horsepower may cause mower damage by overpowering the unit in heavy cutting conditions.
Tractor 3-Point Lift
The tractor 3-point hitch must be rated to lift at least 675 lbs if attaching a HDTH5, 740 lbs if attaching a HDTH6.
The mower is designed to be mounted on tractors with a CAT I or Quick Attach Hitch. Refer to the tractor operator’s
manual for the category of the tractor being used.
If the hitch does not conform to ASAE CAT I dimensions or CAT l Quick Attach Dimensions the mower may not
fit or raise properly. Consult an authorized dealer for possible modification procedures to mount non-conforming
hitches.
Use the correct hitch pins for the hitch category being used.
CAT I Standard Hitch, 7/8” lower and 3/4” upper diameter hitch pins. (Refer to Figures 3-3 & 3-5).
CAT l Quick Attach Hitch, 1-7/16” Lower and 1-1/4” upper hitch pins diameter. (Refer to Figures 3-4 &
3-5).
Front End Weight
A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end
weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the
front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front weights and weight
carriers can be purchased through an authorized tractor dealership.

Power Take Off (PTO)
NOTE: These mowers are designed for 540 RPM (PTO) speeds only.
Depending on the unit, the mower is designed to operate at a PTO speed of 540 or 1000 RPM. Most tractors
operate at either 540, or a combination of 540 and 1000 RPM PTO speeds. The operating speed of the mower
and tractor can be determined by the number of splines on the driveline yoke and PTO output shaft.
Those operating at 540 RPM will have a 6-spline 1-3/8” diameter shaft and those operating at 1000 RPM will
have a 20-spline 1-3/4” diameter or 21-spline 1-3/8” diameter shaft. Note: Refer to the tractor owners manual
for instructions to change PTO speeds on models that operate at more than one speed.
If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an over-
running clutch must be used between the PTO output shaft and the driveline of the mower. An authorized tractor
dealer can provide the over-running clutch and its installation if needed. OPS-U- 0006_ARPM.
DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor
PTO. Use of an adapter can double the operating speed of the Implement resulting in ex-
cessive vibration, thrown objects, and blade and implement failure. Adapter use will also
change the working length of the driveline exposing unshielded driveline areas. Serious
bodily injury and/or equipment failure can result from using a PTO adapter. Consult an
authorized dealer for assistance if the Implement driveline does not match the Tractor
PTO. (S3PT-14)
Never operate the Tractor and Mower if the Implement input driveline is directly connected
to the Tractor transmission. Tractor braking distances can be substantially increased by
the momentum of the rotating Mower blades driving the Tractor transmission even though
the Tractor clutch has been disengaged. Install an over running clutch between the Tractor
PTO and the Mower driveline to prevent this potentially dangerous situation. (S3PT-16)
Tire Spacing (Figure 4-1)
Tractor tires should be set a minimum of 60”
(1.524 Centimeters) apart. Measured from inside
of the tire to inside of the tire.
Refer to the tractor Operator’s Manual or consult
an authorized dealer for instructions to change
tractor tire spacing.

OPERATION
GETTING ON AND OFF THE TRACTOR
Before getting onto the tractor, the operator must read and completely understand the implement and tractor
operator manuals. If any part of either manual is not completely understood, consult an authorized dealer for a
complete explanation. OPS-U- 0007
Do not mount or dismount the Tractor while the tractor is moving. Mount
the Tractor only when the Tractor and all moving parts are completely
stopped. (SG-12)
Boarding the Tractor
Use both hands and equipped handrails and steps for support when boarding the tractor. Never
use control levers for support when mounting the tractor. Seat yourself in the operator’s seat and secure the
seat belt around you.
Never allow passengers to ride on the tractor or attached equipment. Riders can easily fall off and be seriously
injured or killed from falling off and being ran over. It is the operator’s responsibility to forbid all extra riders at
all times. OPS-U- 0008
Never allow children to operate, ride on, or come close to the Tractor or
Implement. Usually, 16-17 year-old children who are mature and respon-
sible can operate the implement with adult supervision, if they have read
and understand the Operator’s Manuals, been trained in proper operation
of the tractor and Implement, and are physically large enough to reach
and operate the controls easily. (SG-11)
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)

After the tractor engine is running, avoid accidental contact with the tractor transmission to prevent sudden and
unexpected tractor movement. OPS-U-0028
Never run the Tractor engine in a closed building or without adequate ventilation. The
exhaust fumes can be hazardous to your health. (SG-23)
Start tractor only when properly seated in the Tractor seat. Starting a tractor
in gear can result in injury or death. Read the Tractor operators manual for
proper starting instructions. (SG-13)
CONNECTING THE MOWER TO THE TRACTOR
Use extreme caution when connecting the mower to the tractor. The mower should be securely resting at ground
level or setting on blocks. Keep hands and feet from under the mower deck and clear of pinch points between
the tractor hitch arms and mower pins. OPS-R-0001
Always shut the Tractor completely down, place the transmission in park, and set the park-
ing brake before you or anyone else attempts to connect or disconnect the Implement and
Tractor hitches. (S3PT-15)

Connecting the Mower (Figure 4-2)
1. Make sure the tractor is equipped with the correct
PTO shaft. Change shafts if needed.
2. Shorten or remove the tractor drawbar to avoid in-
terference when raising and lowering the mower.
3. Board the tractor and start the engine. Position the
tractor to the mower with the 3-point lift arms posi-
tioned at the same height and to the outside of the
mower hitch pins. Note: Set the 3-point lift control to
“Position Control” so that the lift arms maintain a
constant height when attaching the mower. See the
tractor Operator’s Manual for correct settings when
attaching 3-point equipment.
4. Turn off the tractor engine, set the parking brake,
place the tractor in park, and dismount.
5. One lift arm at a time, position the tractor lift arms

DRIVELINE ATTACHMENT (Figure4-4)
The driveline yoke and tractor PTO shaft must be dirt free
and greased for attachment. Connect the driveline yoke
with the Push Pin to the gearbox input shaft of the mower.
To connect the mower driveline to the tractor PTO output
shaft, pull the driveline yoke collar back and align the
grooves and splines of the yoke with those of the PTO
shaft. Push the driveline yoke onto the PTO shaft, re-
lease the locking collar, and position the yoke until the
locking collar balls are seated onto the PTO shaft. Push
and pull the driveline back and forth several times to en-
sure a secure attachment.
OPS R 0003_A
When attaching the Implement input driveline to the Tractor PTO, it is important that the connect-
ing yoke spring activated locking collar slides freely and the locking balls are seated securely in
the groove on the Tractor PTO shaft. Push and pull the driveline back and forth several times to
ensure it is securely attached. A driveline not attached correctly to the Tractor PTO shaft could
come loose and result in personal injury and damage to the Implement.

Driveline Length Modification
Before operating the Implement, check to make sure the Implement input driveline will not bottom
out or become disengaged. Bottoming out occurs when the inner shaft penetrates the outer hous-
ing until the assembly becomes solid-it can shorten no more. Bottoming out can cause serious
damage to the Tractor PTO by pushing the PTO into the Tractor and through the support bearings
or downward onto the PTO shaft, breaking it off. A broken driveline can cause personal injury.
When fitting the mower to the tractor, the telescoping driveline must be inspected to ensure that at its most compressed
position, the profiles do not “bottom out”, and when at its farthest extended position, there is sufficient engagement
between the profiles to operate safely. At its shortest length, there must be at least a 1” clearance between each profile
end and opposite profile universal joint. At its farthest operating extension, a minimum profile engagement of 8-1/2”
must be maintained.
Bottoming Out Check Procedure (Figure 4-5)
Disconnect Driveline from the tractor and slide the pro-
files together untill fully compressed.
Place mark on the inner shield 1/8” from the end of the
outer shield.
Reattach the driveline to the tractor PTO shaft.
Raise the mower from the lowest to the highest posi-
tion and watch the driveline as it approaches the mark.
If the distance between the mark and the end of the
outer shield tube becomes less than 2” at any point,
the driveline must be shortened.
NOTE: When raising the mower, clearence must be
maintained between driveline and mower deck. If nec-
essary set stop on 3Pt. lift control lever to limit the lift
height of the mower.
Shorten the Driveline Profiles as follows
(Figure 4-6)
Remove Driveline from tractor PTO shaft.
Position the mower to the point with the shortest dis-
tance between the tractor PTO shaft and the cutter
gearbox. Shut down the tractor and securely block the
mower in this position.
Pull driveline apart and reattach yoke to the PTO Shaft.
Hold the driveline sections parallel to one another and
measure 1” back from the yoke of each shaft and place
a mark on the opposite section. Cut this length with a
saw,
Round off all sharp edges and debur.
Throughly grease the reinstall the driveline.
● Recheck for propern operation.

SETTING THE MOWER
Properly setting the cutting height is essential for efficient and safe operation. A properly set mower will make a
more uniform cut, distribute clippings more evenly, require minimal tractor work, and follow the contour of uneven
terrain. NOTE: Avoid very low cutting heights, striking the ground with the blades gives the most damaging shock
loads and will cause damage to the mower and drive. Blades contacting the ground may cause objects to be
thrown out from under the mower deck. Always avoid operating the mower at a height which causes the blades to
contact the ground. OPS U 0010
Never work under the Implement, the framework, or any lifted component
unless the Implement is securely supported or blocked up to prevent sudden
or inadvertent falling which could cause serious injury or even death. (SG 14)
Cutting Height Adjustment (Figure 4-7 & Table 4-1)
The mower comes with four 1” spacers and one 1/2” spacer attached to each caster assembly. The height adjustment is from
1-1/2” to 6” cutting height in 1/2” increments.

DRIVING THE TRACTOR AND IMPLEMENT
Safe tractor transport requires the operator possess a thorough knowledge of the model being operated and precau-
tions to take while driving with an attached implement. Ensure the tractor has the capacity to handle the weight of the
implement and the tractor operating controls are set for safe transport. To ensure safety while driving the tractor with
an attached implement, review the following. OPS-U- 0012
This Implement may be wider than the Tractor. Be careful when operating or transporting this
equipment to prevent the Implement from running into or striking sign posts, guard rails, concrete
abutments or other solid objects. Such an impact could cause the Implement and Tractor to pivot
violently resulting in loss of steering control, serious injury, or even death. Never allow the Imple-
ment to contact obstacles. (S3PT-12)
Transport only at speeds where you can maintain control of the equipment.
Serious accidents and injuries can result from operating this equipment at high
speeds. Understand the Tractor and Implement and how it handles before transporting on streets
and highways. Make sure the Tractor steering and brakes are in good condition and operate prop-
erly.
Before transporting the Tractor and Implement, determine the proper transport speeds for you and
the equipment. Make sure you abide by the following rules:
Test the tractor at a slow speed and increase the speed slowly. Apply the Brakes smoothly to de-
termine the stopping characteristics of the Tractor and Implement. As you increase the speed of
the Tractor the stopping distance increases. Determine the maximum transport speed not to exceed
20 mph (30 kph) for transporting this equipment.
Test the equipment at a slow speed in turns. Increase the speed through the turn only after you de-
termine that the equipment can be operated at a higher speed. Use extreme care and reduce your
speed when turning sharply to prevent the tractor and implement from turning over. Determine the
maximum turning speed for you and this equipment before operating on roads or uneven ground.
Only transport the Tractor and Implement at the speeds which allow you to properly control the
equipment.
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes or worn
tires. When operating down a hill or on wet or rain slick roads, the braking distance increases: use
extreme care and reduce your speed. When operating in traffic always use the Tractor’s flashing
warning lights and reduce your speed. Be aware of traffic around you and watch out for the other
guy. (SG-19)

Starting the Tractor
The procedure to start the tractor is model specific. Refer
to the tractor operator’s manual for starting procedures
for your particular tractor. Consult an authorized dealer if
the starting procedure is unclear. Ensure the 3-point con-
trol lever is in the lowered position and the PTO is disen-
gaged before starting the tractor. OPS-U-0033
Brake and Differential Lock Setting
Make sure the tractor brakes are in good operating con-
dition. Tractor brakes can be set to operate independently
allowing single rear wheel braking action or locked to-
gether to provide simultaneous rear wheel braking. FOR
MOST DRIVING AND OPERATING CONDITIONS, THE
BRAKE PEDALS SHOULD BE LOCKED TOGETHER TO
PROVIDE THE MOST EFFECTIVE BRAKING ACTION.
Always disengage the tractor differential lock when turn-
ing. When engaged the differential lock will prevent or limit
the tractor from turning. During normal cutting conditions,
locking the differential provides no benefit and should not
be used. OPSU- 0013
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes. When
operating down a hill or on wet or rain slick roads, the braking distance increases; use extreme
care and reduce your speed in these conditions. When operating in traffic, always use the Tractor’s
flashing warning lights and reduce your speed. Be aware of traffic around you and watch out for

Raising the Mower
Using the tractor 3-point hitch control lever, raise the
mower off the ground about 6”, or just high enough to
clear any ground obstacles. When raising the mower,
make sure all connection points are securely attached
and at least 1” clearance is maintained between the dri-
veline and the deck. If necessary, place an upper lift stop
on the 3-point hitch control lever to limit the height the
mower can be raised to avoid driveline damage
. OPS R
0042_C
Operating the Tractor and Mower
Start off operating at a slow speed and gradually increase your speed while maintaining complete control of the tractor
and mower. Moving slowly at first will also prevent the tractor from rearing up and loss of steering control. The tractor
should never be operated at speeds that cannot be safely handled or which will prevent the operator from stopping
quickly during an emergency. If the power steering or engine ceases operating, stop the tractor immediately as the
tractor will be difficult to control.
Perform turns with the tractor and mower at slow speeds to determine how the tractor with an attached mower handles
a turn. Determine the safe speed to maintain proper control of the tractor when making turns. When turning with a
towed implement, the overall working length of the unit is increased. Allow additional clearance for the mower when
turning.
To avoid overturns, drive the tractor with care and at safe speeds, especially when operating over rough ground, cross-
ing ditches or slopes, and turning corners. Tractor wheel tread spacing should be increased when working on inclines
or rough ground to reduce the possibility of tipping.
Use extreme caution when operating on steep slopes. Keep the tractor in a low gear when going downhill. DO NOT
coast or free-wheel downhill.
Crossing Ditches and Steep Inclines
When crossing ditches with steep banks or going up
sharp inclines, it is possible that the main driveline inner
profile will penetrate into the outer housing to its maxi-
mum depth until the assembly becomes solid (driveline
is at its extreme shortest length). This type of abusive op-
eration can cause serious damage to the tractor and
mower drive by pushing the PTO into the tractor and
through the support bearings or downward onto the PTO
shaft, breaking it off.
HDTH 5 & 6 Finish Mower 06/19

OPERATION
OPERATION
Damage resulting from over-collapse of the driveline’s inner profile and its outer housing may
allow the driveline to come loose from the Tractor which could cause bodily injury to the operator
or bystanders and/or extensive damage to the Tractor or Implement. OPS-R-0020
When confronted with an incline or ditch, do not approach
from an angle which is perpendicular or straight on as
damaged to over collapse of the driveline may occur.
When crossing such terrain, the implement should be fully
lowered for a lower center of gravity and added stability.
OPS-R-0021
Inclines and ditches should be approached along a line
which is at an angle as shown. This type of path will re-
duce the possibility of over-collapse of the driveline and
resulting damage. If the gradient is so steep that such an
approach increases the possibility of a tractor roll-over, se-
lect an alternate crossing path.
When operating the tractor and mower across slopes and
inclines, through ditches, and other uneven terrain condi-
tions, it is important to maintain sufficient deck to ground
clearance. Blade contact with the ground may cause soil,
rocks and other debris to be thrown out from under the
mower resulting in possible injury and/or property dam-
age.
Ground contact also produces a severe shock load on the
mower drive and to the mower blades resulting in possible
damage and premature wear.

OPERATING THE TRACTOR AND IMPLEMENT
THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE TRACTOR AND IMPLEMENT
AND ALL CONTROLS BEFORE ATTEMPTING TO OPERATE. The operator must read and understand the Safety
and Operation Sections of the implement and tractor operator’s manuals. These manuals must be read and explained
to any operator who cannot read. Never allow someone to operate the implement and tractor without complete oper-
ating instructions.
Before starting any operation, the operator must become familiar with the area to be worked in and any obstacles and
hazards contained within to ensure safety to the operator, bystanders, and equipment. Special attention should be
paid to foreign debris, rough terrain, steep slopes, and passersby and animals in the area. OPS-U- 0015
Extreme care should be taken when operating near loose objects such as
gravel, rocks, wire, and other debris. Inspect the area before mowing. Foreign
objects should be removed from the site to prevent machine damage and/or
bodily injury or even death. Any objects that cannot be removed must be clearly
marked and carefully avoided by the operator. Stop mowing immediately if
blades strike a foreign object. Repair all damage and make certain rotor or
blade carrier is balanced before resuming mowing.
(SGM 05)
Many varied objects, such as wire, cable, rope, or chains, can become entangled in the operating
parts of the mower head. These items could then swing outside the housing at greater velocities
than the blades. Such a situation is extremely hazardous and could result in serious injury or even
death. Inspect the cutting area for such objects before mowing. Remove any like object from the
site. Never allow the cutting blades to contact such items. (SGM 06)
Foreign Debris Hazards
Before mowing, inspect the area to make sure there are no foreign objects that
the mower blades could hit or become entangled with. Remove all foreign ob-
jects and debris. If objects are too big to remove, mark them clearly and be
sure to prevent the mower blades from contacting them.
If you hit a solid object or foreign debris, stop the mower and tractor at once.
Immediately idle the engine speed and disengage the PTO. Wait for all mower
rotating motion to stop, then raise the mower and move the tractor and imple-
ment off the object. Inspect the area and remove, or mark the location of the
debris. Inspect the condition of the mower and make any needed repairs im-
mediately. Make sure the blades are not damaged and the carrier is balanced
before resuming operation.
Always wear your seat belt securely fastened and only operate the tractor and
mower with the ROPS in the raised position. If the tractor or mower hits a tree
stump, rock, or bump, a sudden movement could throw you off of the seat and
under the tractor and/or mower. The seat belt is your best protection from
falling off the tractor and the ROPS provides protection from being crushed
during a tractor roll-over. OPS-R-0023

Bystanders/Passersby Precautions
Rotary Mowers are capable under adverse conditions of throwing objects for
great distances (300 feet or more) and causing serious injury or death. Follow
safety messages carefully.
If a bystander comes within 300 feet of the tractor while the mower is being operated, stop the tractor at once,
idle the engine and disengage the PTO. Do not engage the PTO again until all bystanders are well past the
300 foot distance.
OPS-R-0024
NOTE: Where there are grass and weeds high enough to hide debris that could be struck by the blades, the area
should be: inspected and large debris removed, mowed at an intermediate height, inspected, closely with any remaining
debris being removed, and mowed again at desired final height. (This will also reduce power required to mow, reduce
wear and tear on the Mower drivetrain, spread cut material better, reduce streaking, and make the final cut more uni-
form).
(SRM 01)
Engaging the Power Take Off (PTO)
Before engaging the PTO, make certain that the area is clear of bystanders and passersby. The implement must be
completely lowered and the deck positioned at a safe operating height. NEVER engage the PTO with the implement
in the raised position.
Set the tractor engine speed at approximately 1,000 RPM before engaging the PTO. Shift the PTO control to the on
position, and slowly increase the engine speed until the PTO is operating at the rated speed. If you hear unusual
noises or see or feel abnormal vibrations, disengage the PTO immediately. Inspect the implement to determine the
cause of the noise or vibration and repair the abnormality. OPS-U- 0027
Do not let the Blades turn when the Mower Deck is raised for any reason, in-
cluding clearance or for turning. Raising the Mower deck exposes the Cutting
Blades which creates a potentially serious hazard and could cause serious in-
jury or even death from objects thrown from the Blades. (SRM-07)
Do not put hands or feet under mower decks. Blade Contact can result in seri-
ous injury or even death. Stay away until all motion has stopped and the decks
are securely blocked up. (SGM-09)

PTO RPM and Ground Speed
Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut. Recommended speed
for efficient mower performance is between 2 and 5 mph(3-8 kph). Operate the mower at its full rated PTO speed to
maintain blade speed for a clean cut. Refer to the tractor operator’s manual or the tractor instrument panel for the en-
gine speed and gear to provide the required PTO and desired ground speed. Make sure that the mower is operating
at its full rated speed before entering the vegetation to be cut. If it becomes necessary to temporarily regulate engine
speed, increase or decrease the throttle gradually.
Ground speed is achieved by transmission gear selection and not by the engine operating speed. The operator may
be required to experiment with several gear range combinations to determine the best gear and range which provides
the most ideal performance from the mower and most efficient tractor operation. As the severity of cutting conditions
increase, the ground speed should be decreased by selecting a lower gear to maintain the proper operating PTO
speed.
OPS R 0025
Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause Im-
plement driveline or blade failures resulting in serious injury or death. (SG 26)
Mow at the speed that you can safely operate and control the tractor and mower. The correct
mowing speed depends on terrain condition and grass type, density, and height of cut. Normal
ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds when operating on
or near steep slopes, ditches, drop-offs, overhead obstructions, power lines, or when debris and
foreign objects are to be avoided.
(SGM 07)
Operating the Mower
The mower is designed to cut grass and light weeds. Travel at a speed that allows the mower sufficient time to cut
through the vegetation and maintain the PTO operating speed to prevent overloading the mower and tractor and to
produce a clean cut. Choose a driving pattern that provides the maximum pass length and minimizes turning. Re-
member, sharp blades produce cleaner cuts and use less power.
Under certain conditions, tractor tires may roll some grasses down preventing them from being cut at the same height
as the surrounding area. When this occurs, reduce the tractor ground speed while maintaining the operating speed of
the mower. A slower ground speed will permit grasses to at least partially rebound and be cut. Taking a partial cut
and/or reversing the direction of travel may also help produce a cleaner cut.
Avoid mowing in the reverse direction when possible. In situations where the mower must be
backed to access areas to be cut, make sure there are no persons or other foreign debris behind
the mower before mowing in reverse. When mowing in reverse, operate the tractor and mower
at a reduced ground speed to ensure control is maintained of the tractor and mower.
OPS R 0026_I
Do not mow with two machines in the same area except with Cab tractors with the windows
closed. (SGM-11)
Mow only in conditions where you have clear visibility in daylight or with adequate artificial lighting.
Never mow in darkness or foggy conditions where you cannot clearly see at least 300 feet (90
m) in front and to the sides of the tractor and mower. Make sure that you can clearly see and
identify passersby, steep slopes, ditches, drop-offs, overhead obstructions, power lines, debris
and foreign objects. If you are unable to clearly see these type of items discontinue mowing.

Follow these guidelines to reduce the risk of equipment and grass fires while
operating, servicing, and repairing the Mower and Tractor:
● Equip the Tractor with a fire extinguisher in an accessible location.
● Do Not operate the Mower on a Tractor with an underframe exhaust.
● Do Not smoke or have an open flame near the Mower and Tractor.
● Do Not drive into burning debris or freshly burned areas.
● Ensure belts are properly adjusted to prevent excessive slippage and over heating.
● Never allow clippings or debris to collect near drivelines, under shielding around belts and pulleys, and gearboxes.
● Periodically shut down the Tractor and Mower and clean clippings and collected debris from the mower deck.
(SGM 12)
Do not let the Blades turn when the Mower Deck is raised for any reason, including
clearance or for turning. Raising the Mower deck exposes the Cutting Blades
which creates a potentially serious hazard and could cause serious injury or even
death from objects thrown from the Blades. (SRM-07)
Stay alert and watch for trees, low hanging limbs, power lines, and other overhead obstacles and
solid ground objects while you are operating. Use care to avoid hitting these items.
When mowing across uneven areas such as road shoulders, ditch edges, and other uneven ter-
rain, position mower so that one support wheel is near the highest point to prevent blades from
cutting into gravel or dirt which can cause rapid blade wear and extremely severe shock loads on the drivetrain resulting
in rapid wear or damage to these components. Blades contacting the ground may cause objects to be thrown out from
under the mower deck. Always avoid operating the mower at a height or position which may cause the blades to
contact the ground. Cutting into the berm or edge of the ditch will cause abnormal and accelerated blade wear and
possible blade component failure.

Shutting Down the Mower
To shut down the mower operation:
1. Bring the tractor to a complete stop on a level surface.
2. Decrease the engine speed (RPM) to idle.
3. Place the transmission in park or neutral and apply the parking brake.
4. Disengage the PTO and wait for the blades to stop turning. (Do Not Disengage the PTO at a High RPM unless it
is an emergency situation).
5. Lower the mower to the ground.
6. Shut down the tractor, remove key and wait for all motion to come to a complete stop before exiting tractor.
DISCONNECTING THE MOWER FROM THE TRACTOR
Always shut the Tractor completely down, place the transmission in park, and set the parking
brake before you or anyone else attempts to connect or disconnect the Implement and Tractor
hitches.
(S3PT 15)
Before disconnecting the mower, the PTO must be dis-
engaged and blade rotation at a complete stop. Move
the mower to a level storage location and lower it to the
ground. If the mower is not resting securely on the
ground, block the mower up securely before attempting
to disconnect it from the tractor. Use extreme care to
keep feet and hands from under the mower and clear
of any pinch points caused by the tractor hitch arms and
mower pins.
OPS R 0030_F
Lift Mower-To disconnect the mower, first extend the tractor 3-point hitch top

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
.
OPS R 0032_D

Equipment and be injured or killed. Inadvertent contact with controls can cause the Implement to
shift or fall crushing themselves or others. (SG-25)
TRANSPORTING THE TRACTOR AND IMPLEMENT
Inherent hazards of operating the tractor and implement and the possibility of accidents are not left behind when you
finish working in an area. Therefore, the operator must employ good judgement and safe operation practices when
transporting the tractor and implement between locations. By using good judgement and following safe transport pro-
cedures, the possibility of accidents while moving between locations can be substantially minimized. OPS-U- 0017
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death. (SG-10)
Before transporting the tractor and mower, idle the tractor

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” clear-
ance between the driveline and mower deck. If additional
mower deck height is needed for safe transport, discon-
nect the driveline from the tractor and secure its end to

Hauling the Tractor and Implement
Before transporting a loaded tractor and implement, meas-
ure the height and width dimensions and gross weight of the
complete loaded unit. Ensure that the load will be in compli-
ance with the legal limits set for the areas that will be trav-
eled through. OPS-U- 0024
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. OPS-U-
0025
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 main-
tained tension. If during transport a hard braking, sharp turn-
ing, or swerving action was performed, stop at the next safe
location to inspect the security of the load. OPS-U- 0026

MAINTENANCE
Before operating your Finishing Mower, make sure it is properly lubricated and thoroughly
inspected. Only a minimum of time and effort is required to regularly lubricate and maintain
this machine to provide long life and trouble free operation.
Lubrication
Do not let excess grease collect on or around parts, particularly when operating in sandy areas.
The illustrations below shows lubrication points. The chart gives the frequency of lubrication in
hours, based on normal operating conditions. Severe or unusual conditions may require more fre-
quent lubrication. MntP-R-0381.
Use Multi-Purpose Gear Oil EP80W-90 when required in Gearbox. Use N.L.G.I.#2 Lithium grease
for all locations requiring application using grease gun. Be sure to clean the fitting thoroughly
before using grease gun. Daily lubrication of the wing driveline slip joint is necessary. Failure to
maintain proper lubrication will result in damage to U-joints, gearbox, and/or driveshaft.

Gearbox Maintenance
The first oil change must be done after 50 hours of working time and then after 400-500 hours of work. Keep in mind
that intense and continuous working conditions will necessitate more frequent oil changes and periodic checks. It is a
good practice to check the oil level every 50-60 hours of work. When changing the oil, detach the mower and driveline
entirely from the tractor. Remove the driveline from the mower. However, depending on the situation and the operator’s
experience, the tools and equipment available, and the area where the oil change is done (in the shop, in the field,
etc.), other procedures may be used provided that the operator is always fully aware of the hazards connected with
this operation.
Never work under the Implement, the framework, or any lifted component un-
less the Implement is securely supported or blocked up to prevent sudden or
inadvertent falling which could cause serious injury or even death. (SG-14)
To change the oil, keeping in mind the preceding safety recommendations, place the mower in a vertical position
(Figure 5-1), or inclined enough so that once the Vent Plug and the 3/8” Check Plug (Figure 5-2) are removed the oil
can drain out of the Check Plug opening. Once the used oil has been completely drained, place the mower back in a
level position and add oil in the Vent Plug opening until it starts to come out of the Check Plug opening. Allow enough
time for the new oil to seep down into the lower housing through the bearings and fill as needed. Put the Vent Plug
and the 3/8” Check Plug back in place when properly filled. For a full oil change, approx. 0.5 liters use EP80W-90
Gear Oil.
The Vent Plug on the housing is for filling, and 3/8” Check Plug on the side is for checking the level (Figure 5-2). To
check the level, simply unscrew the 3/8” Check Plug and see if the oil reaches the lower part of the opening. To fill oil,
remove the Vent Plug and add oil until it starts to come out of the opening for the 3/8” Check Plug. Re-install the Vent
Plug and the 3/8” Check Plug.

The Driveline should be serviced every 8 hours of operation. Refer to (Figure 5-3)
1. Disconnect the driveline from the Tractor PTO and from the Gearbox input shaft.
2. Pull the driveline halves apart.
3. Release the Shield Cones from the shield tubes by pressing down on the retaining tabs located under the access
holes on the back of the shield cones (there are 3 tabs on each cone) and separate the shield tubes from the
cones exposing the driveshaft inner and outer tubes.
4. Thoroughly clean old grease from the tubes and apply a thin coat of multi-purpose grease to the outside of the
inner tube (male) section.
5. Re-assemble the shielding on the two halves and then re-assemble the driveline halves.
6. Put 1 or 2 shots of grease in the lube points for the shield bearing locations.
7. Grease the Cross Bearing in the fittings on both ends of the shaft.
8. Apply a lite coat of oil to the Slide Collar (Tractor End) and the Push Pin (Implement End) to prevent rust from
forming making their functions difficult.
9. Re-attach the Driveline to the Gearbox Input Shaft and then to the Tractor PTO shaft.
10. Pull on each end of the shaft to make sure the shielding is secure to the Driveline and the driveline is securely at-
tached to the PTO Shaft and the Input Shaft of the Gearbox.

BLADE SPINDLE and BELT TENSION IDLER ARM
LUBRICATION & MAINTENANCE
The area beneath the shielding must be cleaned of debris such as grass clippings and twigs to prevent buildup, causing
friction on belt and pulleys. Clean any lubricant accumulation occuring during the lubrication procedures.
Check drive pulleys and idler pulleys for excessive wear or damage. Replace if needed.
Check Belt Tensioner Idler Arm for excessive wear / looseness and freedom of movement.
Blade spindles (Figure 5-4) must be greased with 5 shots of grease every 10 hrs. Access lubrication fittings through
holes in top of the shielding above the Spindle Assembly. Occasionally grease the spindle until a small amount of
grease purges from the relief hole (Figure 5-5), located at the base of the spindle housing under the sheave. The
shielding will need to be removed in order to see the relief hole. Clean off any excess grease. The Belt Tension Idler
Arm should be greased each time the blade spindles are greased with 3 shots of grease.
NOTE: Do not over lube as excess grease may get on belt drive and cause belt slippage.

BLADE SERVICING
Inspect blades before each use to determine that they are properly installed and in good condition. Replace any
blade that is bent, excessively nicked, worn, or has any other damage. Small nicks can be removed by sharpen-
ing.
Use only original equipment blades on this cutter. They are made of special heat-treated alloy
steel. WILL-FIT BLADES MAY NOT MEET SPECIFICATIONS AND MAY FAIL CATA-
STROPHICALLY AND CAUSE BODILY INJURY OR DEATH.
Replace bent or broken blades with new blades. NEVER ATTEMPT TO STRAIGHTEN,
WELD, OR WELD HARDFACING ON BLADES SINCE THIS WILL LIKELY CRACK OR OTH-
ERWISE DAMAGE THE BLADE WITH SUBSEQUENT FAILURE AND POSSIBLY CAUSE
SERIOUS INJURY FROM THROWN BLADES. (SGM-10)
Inspect Blades daily for abnormal wear. If Blades have a notch worn into the leading edge at
the lower bend more than a 1/2” DEEP (due to running in gravel and/or contact with the
ground), REPLACE BLADES ON THAT CARRIER IMMEDIATELY. Failure to replace such
abnormally worn blades may lead to catastrophic failure of the blade and ejection of the bro-
ken part with tremendous force which may cause bodily injury or death!
NOTE: Replace Blades after no more than 1/2" notch wear!
BLADE SHARPENING
Always sharpen both cutting edges of each blade at the same time, the same amount, to maintain balance. Follow
original sharpening pattern as shown. Do not sharpen blade to a razor edge, but leave a 1/32” blunt edge. Do not
sharpen back side of blade. Figure Mnt-R-0303.
When sharpening blades, grind each blade the same amount to maintain balance. Unbalanced blades will cause
excessive vibration which can damage gear box bearings. Vibration may also cause structural cracks in cutter
housing.
Never work under equipment supported by a hydraulic device because it may drop if the
control is actuated (even with the engine stopped) or in the event of hose failure, etc. Always
use a secure support for equipment which must be serviced while in the raised position.

BLADE REMOVAL
Never work under the implement, or any lifted component unless the imple-
ment is securely supported or blocked to prevent sudden or inadvertant falling
which can cause serious injury or death.
The replacement of the blades must be done using maximum caution, and always with the tractor shut off and the dri-
veshaft disconnected from the tractor. Raise the mower body to the maximum height possible with the tractor power-
lift so as to allow you to work properly on the underneath part of the mower.
1. Support the raised machine with suitable supports under the mower frame and support the raised machine with a
suitable over head hoist capable of supporting the implements weight.
2. Remove the Blade Bolt, Cup Washer, Blade and Blade Washer. (Figure 5-6)
BLADE INSTALLATION (Figure 5-6)
1. Place the cup washer on the blade bolt with the convex side to the blade bolt head.
2. With the blade cutting edge toward the ground and the offset up, place thebladebolt with the cup washer through
the blade.
3. Place the smooth side of the blade washer to the top of the blade inserting the blade bolt through the blade washer.
4. Start the blade bolt in the spindle aligning the blade washer with the spindle housing.

BELT REMOVAL, REPLACEMENT and ADJUSTMENT
The mower drive belt should be checked after every 40 hours of use for unusual wear, cracking, fraying or pieces
missing. Belts that are too loose or too tight will not give good service and will not last as long. Replacing and /or ad-
justing belt should be performed using maximum cauton. Protective shielding will need to be removed to replace the
belt or adjust the belt tension.
Belt Removal and Replacement (Figure 5-7)
Note: Use only Genuine Bush Hog Belts for replacement. Will Fit (after market belts) may not meet the re-
quirements for usage in belt life and mower performance.
1. Park the mower on a firm level surface. Lower the implement to the ground. Shut the tractor down, set parking
brake and dismount.
2. Disconnect the driveline from the input shaft of the gearbox on the mower.
3. Remove the two outer belt shields and the center shield, retain the fasteners for re-installation.
4. Relieve the tension on the belt by loosening the two 3/8” hex nuts on the tensioner rod.
5. Remove the old belt.
6. Install the new belt referring to (Figure 5-7) for correct belt routing. There is also a decal on the mower deck you
may refer to showing the correct belt routing.
7. Refer to (Figure 5-8) Belt Adjustment for correct setting of belt tension.
Belt Ajustment (Figures 5-7 & 5-8)
Tension on the mower belt is achieved by tightening the
3/8” hex nut against the tensioner bracket until the proper
spring length is reached. This length is measured from
the center of the spring attaching hole of the tensioner
rod to the center of the mounting pin on the idler arm. The
spring length should be set to between 7” to 7½” as
shown in (Figure 5-8).
Loosen the outer 3/8” hex nut on the tensioner rod and
then turn the hex nut aginst the tensioner bracket to
lengthen or shorten the spring length. When the proper
length is set, turn the outer hex nut to contact adjusting
nut to lock the position.

las mangueras, usar mangueras del tipo correcto, mantener la presión operativa especificada y prevenir el
posible riesgo de que el aceite penetre en la piel.
IMPLEMENTOS PLEGABLES: He explicado que no es posible proteger contra objetos arrojados cuando el
cabezal está elevado del suelo y que el operador es responsable de verificar que no existan personas en las
inmediaciones. He explicado que el brazo o cabezal de cortadora elevado puede entrar en contacto con
obstrucciones elevados y dañar cables y líneas telefónicas, y posiblemente causar lesiones. He explicado que
el brazo o cabezal extendido, o el brazo retraído, puede entrar en contacto con cables de alimentación y
causar lesiones o la muerte por electrocución, y que el operador es responsable de evitar dichos riesgos.

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 Bush Hog 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.

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
Bush Hog o descargarlo del sitio web de Bush Hog (www.bushhog.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 Bush Hog determinarán en gran medida su satisfacción con el
desempeño y la vida útil del equipo. Lea con atención y siga las instrucciones de este manual para comprender
cabalmente su nuevo implemento, su uso previsto, y sus requisitos de servicio.
Todas las referencias que se hacen en este manual a derecha, izquierda, frontal, trasero, arriba y abajo
corresponden a la perspectiva en el sentido del desplazamiento hacia delante con el implemento correctamente

La información sobre repuestos se encuentra por separado en el Manual de Partes. Las cortadoras Bush Hog
utilizan componentes del sistema equilibrados y coincidentes para porta cuchillas, cuchillas, ejes de corte, hojas,
ganchos para hojas, rodillos, componentes de los engranajes, y cojinetes. Estas partes se fabrican y se prueban
según las especificaciones de Bush Hog. Las partes compatibles no genuinas no siempre cumplen con estas
especificaciones. El uso de partes no genuinas puede perjudicar el desempeño de la cortadora, anular la garantía
y presentar un riesgo para la seguridad. Use partes genuinas Bush Hog para ahorrar dinero y maximizar la
seguridad.
Para referencia futura, registre el número de modelo y el número de serie de Bush Hog que ha adquirido.
