DANGER: Failure to observe the following
safety instructions can result in serious
injury or death. As the owner or operator
of the tractor, you are responsible for pre-
venting accidents or injuries.
1.HOW TO BE A SAFE OPERATOR
1.1. Follow all the safety signs on the tractor and all
the manufacturer’s instructions before starting the
tractor. If you do not, it may result in body injuries.
1.2. Pay attention to the caution labels on the tractor
and mower deck and observe the instructions
they give to avoid physical injuries.
1.3. Ensure that all operators are responsible individu-
als who have read the instructions or been fully
trained on the safe operation of the tractor.
1.4. All operators should evaluate their health and
ability to operate a tractor safely enough to pro-
tect themselves and others from serious injury.
Do not operate the tractor while you are under the
influence of alcohol or drugs.
1.5. Understand how to properly and safely operate
and maintain the tractor. Seek and obtain practi-
cal instruction on how to operate and maintain the
tractor properly.
1.6. Be sure to use necessary protective devices such
as headgear, safety glasses, safety shoes, ear
plugs, gloves, etc.
1.7 Wear appropriate protective clothing and equip-
ment when you are operating, adjusting, or
servicing the tractor, such as safety glasses, long
pants, substantial footwear, and ear protection.

1.9. Inspect the tractor periodically. If not, this may
not only shorten the tractor’s service life but also
make safe and efficient operation impossible.
1.10. Never use the tractor out of normal usage even
if it is not mentioned at this manual.
2.BEFORE STARTING THE TRACTOR
2.1. Set up an operation plan with sufficient time al-
lowance. A tight plan may result in unexpected
accidents. Especially when operating the tractor
under extremely hot, cold, or humid circum-
stances, set up an operation schedule or method
which will ensure operational safety.
2.2. Mow only in daylight or good artificial light. Mow-
ing in the dark may cause unexpected accidents.
2.3. Thoroughly inspect the mowig area and remove
all objects from the mowing area that the tractor
can throw, such as stones, toys, sticks, and wires,
which may lead to serious accidents.
2.4 Ensure that there are no people or pets in the
area where you will mow. Keep children out of
the mowing area and under the watchful care of a
responsible adult.
2.5. Do not operate the tractor unless the operator’s
presence controls, safety switches, and guards
are attached and functioning properly.
2.6. Start the engine from the operating or designated
starting position.
2.7. Before starting the engine, make sure that ev-
erything is safe around the tractor and put the
traction drive in neutral, set parking brake, and
disengage the cutting unit(s). Otherwise, unex-
pected accidents may occur.
2.8. Start the engine with the starter switch only.
Never attempt to start the engine by shorting the
terminals, or the tractor may move abruptly, and
result in unexpected accidents.
2.9. Do not run the engine in an enclosed area where
dangerous carbon monoxide fumes can collect.
Sufficient ventilation shoud be provided when
starting the engine in an enclosed area.
2.10. Make sure of safety around the tractor and
move slowly when starting. Abrupt starting may
cause unexpected accidents.
2.11. Become familiar with the operation, particularly,
the stopping of the tractor. You should be skilful
enough to be able to stop the tractor at will.

2.12. Use only attachments and accessories ap-
proved by the manufacturer and install and
operate them as directed.
2.13. When your tractor is equipped with an imple-
ment other than a standard mower deck, such
as a collector, a cabin, etc., never fail to ask
your dealers about machine balance. Always
follow their advice.
2.14. Keep in mind that the operator or user is re-
sponsible for the accidents or hazards caused
by the tractor to other people or their property.
2.15. Inspect the tractor for wear or damage. Re-
place any worn or damaged parts.
2.16. Especially before starting the tractor, be sure
to perform advised pre-operation inspections
especially on the brakes and inspect visually
to see that the blade and blade tightening nuts
are not worn, damaged or loose. Replace worn
or damaged blade and nuts as an assembly
to preserve blade balance. Otherwise, poor
braking or scattered broken blades may result,
which is very dangerous.

3.OPERATION OF THE TRACTOR
3.1. When the tractor is running, stay away from the
discharge hole, the cutting unit(s), and all moving
parts.
3.2. During operation, never allow anyone, especially
children, and animals to be in the vicinity of the
tractor. Do not direct the discharge at anyone.
3.3. When you are working with co-workers, be sure
to alert them by signalling before you take a
new action.
3.4. When operating the tractor, you should be seated
in the operator’s seat properly, hold the steering
wheel by both hands, and look in the direction
in which the tractor advances. Avoid looking a
side or holding the steering wheel by one hand
during operation.
3.5. Always be sure to operate the tractor from the
driver’s seat with seat belt. Never attempt to get
on or off the tractor while it is travelling.
3.6. Do not mow on wet grass. The tractor may slip.
3.7. Slow down before turning the tractor. Turning at
high speed may cause the tractor to turn over.
3.8. Never attempt to depress the dif-lock pedal while
turning around the tractor. Turning with the dif-
lock on may cause the tractor to turn over.
3.9. Connect the independent brake pedal except nec-
essary situation. Never operate the independen-
dent brake pedal during travelling as this will cause
the tractor to skid sideways or turn over. When
stopping, be sure to use the master brake pedal.
3.10. Look down and behind you and ensure a clear
path before you move the tractor backward.
3.11. Do not mow while moving backward unless it is
absolutely necessary.
3.12. Never operate the tractor in terrain where there
are ditches, holes, or steps easy to collapse. In
such a place, the tractor could turn over or fall.
3.13. Before making access to moving parts, stop the
engine, and keep your hands, feet, clothing, ac-
cessories and etc. away so as not to be caught
in the moving parts of the tractor.
3.14. Be alert when you approach blind corners and
objects that may obscure your vision. Watch
for holes, ruts, or bumps. Tall grass can hide
obstacles.

3.15. Never rest a foot on the brake pedal. If so, the
brakes disc wear rapidly, which may lead to
serious accidents.
3.16. Travelling set with the cruise lever should be
restricted only to operations in specious, flat
areas with an unobstructed view and used with
the range shift lever always kept in the low
speed position.
3.17. Never attempt to do the mowing operation
without the discharge cover in place or with the
cover left open.
3.18. Never attempt to operate without the drive shaft
cover in place.
3.19. Do not attempt to adjust the cutting height while
the engine is running.
3.20. Adjust the cutting height with the gauge wheels
in accordance with the condition of the ground
surface at the working site. Mowing on rough
ground with low cutting height may cause
the blades to hit soil or stones, which is very
dangerous.
3.21. If you strike an object or if the tractor vibrates
abnormally, stop the tractor immediately, wait
for all moving parts to stop, and inspect the cut-
ting unit(s). Make all repairs before you resume
operation.
3.22. Be sure to keep the grass discharging part
clean. A clogged discharging part may cause
the discharge cover to open, resulting in
scattering of grass and stones, which is very
dangerous.
3.23. Never allow grass or leaves to accumulate
around heated parts such as the engine and
the muffler, or this may cause a fire.
3.24. Before moving the tractor to another place,
be sure to stop the mower blades and lift up
the mower deck. Otherwise, they may hit
stones and scatter them around, which is very
dangerous.

3.25. When driving over a levee, stop the mower
blades, lift up the mower deck, and move the
tractor straight to the levee and make it climb
over slowly. Avoid climbing over a levee too high,
or the tractor may fall sideways or turn over.
3.26. Stop the cutting unit(s) when you are crossing
gravel areas.
3.27. Watch for traffic when you are operating the
tractor near a roadway or when crossing a
roadway.
3.28. Never attempt to use the tractor to draw an
implement or a trailer. It is not designed to draw
a load.
3.29. Stay alert and stop the tractor if people or pets
enter the area.
3.30. Do not carry passengers.
3.31. Never carry children, even when the cutting
means are not moving. Children may fall off
the tractor and become seriously injured or
prevent you from operating the tractor safely.
Children who have been given rides in the past
may suddenly appear in the mowing area for
another ride and be run over or backed over by
the tractor.
3.32. Before stopping the engine, be sure to lower
the mower deck onto the ground, apply the
parking brakes, shift the range shift lever in
neutral and turn the PTO switch to the OFF
position.
3.33. Before leaving the operating position of the
tractor for any reason, always do the following:
- Stop the tractor on level ground.
- Stop the cutting unit(s), disengage PTO, and
lower the attachment(s).
- Disengage the drive(s).
- Set the parking brake.
- Stop the engine and wait for all moving parts
to stop.
