SAFE OPERATION
Careful operation is your best insurance against an accident. Read and understand this section carefully before operation.
All operators, no matter how experienced they may be, should read this and other related manuals before operation of the
machine or any implement attached to it. It is the owner's obligation to instruct all operators in safe operation.
This cutting machine is capable of amputating hands and feet and throwing objects. Failure to observe the following safety
instructions could result in serious injury or death.
15.Carefully check the area to be mowed and clear any
1. BEFORE OPERATING
1. Know your equipment and its limitations. Read,
understand and follow all instructions in this manual
before attempting to start and operate the machine.
2. Know the controls and how to stop quickly.
3. Pay special attention to the safety labels on the
machine and mower.
4. The exhaust gas from the muffler is very hot. To
prevent fire, do not expose dry grass, mowed grass, oil
or any other combustible materials to exhaust gas.
Use a spark arrester where required. Also keep the
engine and muffler clean all the time. Replace the
muffler if it has a fault.
5. Never wear loose, torn, or bulky clothing. It may catch
on moving parts or controls, leading to the risk of
accident. Safety boots or shoes, eye and hearing
protection, gloves, dust mask, etc. are recommended.
6. While mowing, always wear substantial foot wear and
long trousers. Do not operate the equipment when
barefoot or wearing open sandals.
7. Do not operate machine or any implement attached to
it while under the influence of alcohol, drugs, or other
substances or while fatigued.
8. Check brakes, and other mechanical parts for faulty
adjustment and wear. Replace worn or damaged parts
promptly. Check the tightness of all nuts and bolts
regularly. (For further details, see "MAINTENANCE"
section.)
9. Keep the machine and attachments in good operating
condition and keep safety devices in place and in
proper working condition.
10.This machine is equipped with many safety devices.
Do not attempt to remove or alter them.
11.Keep all shields and guards in place. Replace all
missing or damaged items for your safety.
12.Never allow any bystanders around or near machine
during operation.
Be sure the area is clear of other people before
mowing.
Stop machine if anyone enters the area.
13.Before allowing other people to use your machine,
explain proper operation to them and have them read
this manual before operation.
14.Never allow passengers or non-qualified operators on
the machine at any time. You must operate the
machine from the seat only.
objects such as rocks, bottles, cans, toys, etc., that
may damage the mower, the grass catcher or cause
personal injury.
16.Keep your machine clean. Dirt, grease, and trash
accumulations contribute to fires or lead to personal
injury.
17.Keep all nuts, bolts, and screws tight to be sure the
equipment is in safe working condition.
Check the mower blade mounting bolts for proper
tightness at frequent intervals. On multi-bladed
mowers, take care as rotating one blade can cause
other blades to rotate.
18.Use only attachments recommended by KUBOTA.
Use proper ballast to front or rear of machine to reduce
the risk of upsets. Follow the "Safe Operation"
procedures, specified in the Equipment's Manual.
19.Follow the maintenance recommendations. See
"MAINTENANCE " section.
20.It is recommended that your machine be thoroughly
inspected at least once a year by an authorized
KUBOTA Dealer.
2. OPERATING
C Starting
1. Never start engine or operate levers from anywhere
other than the seat.
2. Before starting the engine, make sure that all levers
(including auxiliary control levers) are in their neutral
positions, that the parking brake is engaged, and that
both the mower clutch and the Power Take-Off (PTO)
are disengaged.
3. Do not start engine by shorting across starter
terminals or by by-passing the safety start switch. The
machine may start and move if normal starting circuitry
is bypassed.
4. Do not operate or idle engine in a poorly ventilated
area. Exhaust contains poisonous carbon monoxide, a
colorless and odorless gas.
C Working
1. Watch where you are going at all times. Watch for and
avoid obstacles. Be alert near trees and other
obstructions.
2. When working in groups, always let others know what
you are doing ahead of time.
1SAFE OPERATION
ENGLISH
SAFE OPERATION2
3. Never try to get on or off a moving machine.
4. When using any attachments, never direct discharge
material toward bystanders. Do not allow anyone near
ENGLISH
the attachments while in operation.
Do not mow when bystanders are present in the
mowing area.
5. To reduce fire hazards, keep the engine exhaust area
free of grass or leaves.
6. Slow down before turning.
7. Turn off blades when not mowing.
8. Mow only in daylight.
9. Be sure rotating blades and engine are stopped and
the key is removed before placing hands or feet near
blades and cleaning blockages or unclogging chute.
10.Shut the engine off and wait for all movement to stop
before unclogging chute.
11.Know what is behind you and disengage power to
mower before backing up. Do not mow while in reverse
unless absolutely necessary and only after
observation of the entire area behind the mower.
12.When mowing for the first time, cut the grass higher
than desired.
This will uncover any unseen object that may damage
the mower or grass catcher.
13.Always inspect the mower and grass catcher after
striking any foreign object. This will insure that all
mower and grass catcher parts are safe and secure
and not damaged.
Repair or replace any damaged parts before restarting.
14.Use only attachment recommended in this manual.
Use proper ballast to front or rear of machine to reduce
the risk of upsets. Follow the "SAFE OPERATION"
procedures specified in the manuals included with the
equipment.
15.Do not operate the mower without either the grass
container or the guard in place.
Be aware of the mower discharge direction and do not
point it at anyone.
16.Watch for traffic when operating near or crossing
roadways.
17.Stop the blades rotating before crossing surface other
than grass.
18.Never leave a running machine unattended.
Always turn off blades, set parking brake, stop engine,
and remove the key before dismounting.
19.Be extremely alert for all other traffic when operating
the mower and grass catcher near public roads or
highways.
20.Do not operate where machine could tip or slip.
Do not operate near ditches, holes, embankments, or
other terrain which may collapse under the machine's
weight. The risk of machine tip-over is increased when
the ground is loose or wet.
21.Raise and dump collected leaves or grass clippings
ONLY while sitting on the operator's seat.
22.Empty the grass container ONLY from a firm and level
surface, with the mower stopped, and the unit
stationary. Dumping the grass container on soft or
uneven ground, or while moving, could cause the unit
to tip over, causing serious injury and extensive
equipment damage.
23.Make sure the dumping area is clear of all bystanders
and pets, before emptying grass clippings or leaves
from the grass container.
24.If the machine starts to vibrate abnormally, disengage
the drive to the attachments, stop the engine and
remove the key. Then check the machine immediately.
C Pulling loads
Use extra care when pulling loads to reduce the risk of
serious personal injury or death due to a machine tip-over.
a) Pull only from the hitch. Never attach loads to the axle
housing or any other point above hitch.
b) Limit loads to those you can safely control.
c) Do not turn sharply.
d) Use care when backing.
e) Use front ballast or wheel weights when suggested in
this Operator's Manual.
C Operation on slopes
Slopes are a major factor related to loss-of-control and tipover accidents, which can result in severe injury or death.
All slopes require extra caution. If you cannot back up the
slope or if you feel uneasy on it, do not mow it. The control
of a ride-on machine sliding on a slope will not be
regained by the application of the brake.
A Do not lift the grass container on a slope.
DO
1. Mow up and down slopes, not across, to avoid
machine tip-over. Stay off hills and slopes too steep for
safe operation.
2. Remove obstacles such as rocks, tree limbs, etc.
3. Stay alert for holes in the terrain and other hidden
hazards. Keep away from drop-offs. Uneven terrain
could overturn the machine. Tall grass can hide
obstacles.
4. Use slow speed.
3SAFE OPERATION
5. Follow KUBOTA's recommendations for wheel
weights or counterweights to improve stability.
6. The weight of grass in the grass container may
increase the possibility of tip over.
7. Keep all movement on slopes slow and gradual. Do
not make sudden changes in speed or direction.
8. Avoid starting or stopping on a slope. If tires lose
traction, disengage the blades and proceed slowly
straight down the slope.
9. If the machine stops going uphill, disengage PTO and
back slowly down.
10.Reduce speed and exercise extreme caution on
slopes and in sharp turns to prevent tip-over or loss of
control.
11.Use special caution when changing direction on
slopes.
DO NOT
1. Do not turn on slopes unless necessary and then turn
slowly and gradually downhill, if possible.
2. Do not use the machine on slopes of more than 11 .
3. Do not mow near drop-offs, ditches, or embankments.
The machine could suddenly turn over if a wheel falls
over the edge of a cliff or ditch, or if an edge caves in.
4. Do not mow on wet grass. Reduced traction could
cause sliding.
5. Do not try to stabilize the machine by putting your foot
on the ground.
6. Do not stop or start suddenly when going uphill or
downhill.
7. Never "freewheel". Do not let the machine travel
downhill with HST pedal at neutral position.

stopped before connecting, disconnecting, adjusting,
cleaning, or servicing any PTO-driven equipment.
3. Use the PTO with KUBOTA approved attachments.
4. USING THE LIFT LINK
1. Use lift link only with authorized attachments designed
for lift link usage.
ENGLISH
C Children
Tragic accidents can occur if the operator is not alert to
the presence of children. Children are attracted to the
machine and the mowing activity. Never assume that
children will remain where you last saw them.
1. Keep children out of the mowing area and under the
watchful care of another responsible adult.
2. Be alert and turn the machine off if children enter the
area.
3. Before and when backing, look behind and down for
small children.
4. Never carry children. They may fall off and be
seriously injured or interfere with safe machine
operation.
5. Never allow children to operate the machine, even
under adult supervision. Local regulation can restrict
the age of the operator.
6. Use extra care when approaching blind corners,
shrubs, trees, or other obstructions that might hide
children from sight.
5. TRANSPORTING
1. Disengage power to attachment(s) when transporting
or not in use.
2. Do not tow this machine. Use a suitable truck or trailer
when transporting on public roads.
3. It is recommended that this machine not be used on
public roads.
4. Use extra care when loading or unloading the machine
into a trailer or truck.
6. SERVICING
1. Before servicing the machine, park the machine on a
firm, level surface, set the parking brake, stop the
engine and remove the key.
2. Securely support machine or any machine elements
with stands or suitable blocking before working
underneath. For your safety do not rely or hydraulically
supported devices, they may leak down, suddenly
drop or be accidently lowered.
SAFE OPERATION4
3. To avoid injury, do not adjust, unclog or service the
mower or grass catcher with the engine running. Make
sure rotating blades are stopped before dismounting
ENGLISH
the riding mower.
4. Disengage power to attachment(s), stop the engine
and remove the key before making any repairs or
adjustments.
5. Allow the machine to cool off before servicing the
engine, muffler, etc.
6. Keep your riding mower clean. Dirt and grass build-up
can cause fires and may lead to serious personal
injury.
Periodically wash the grass container to insure the
safety signs can be read.
Replace all safety signs that are damaged, lost or have
otherwise become illegible. If a part to be replaced has
a sign on it, obtain a new safety sign from your
KUBOTA Dealer and install it in the same place as on
the removed part.
7. Use extra care in handling diesel fuels. They are
flammable.
(1) Use only an approved container.
(2) Do not remove fuel cap or refuel with the engine
running. Allow engine to cool before refueling. Do
not smoke while refueling or when standing near
fuel.
(3) Do not refuel the machine indoors and always
clean up spilled fuel or oil.
(4) Do not store the machine or fuel container inside
where there is an open flame, such as in a water
heater.
(5) If the fuel tank has to be drained, this should be
done outdoors.
(6) Replace all fuel tanks and container caps
securely
8. Do not change the engine governor setting or
overspeed the engine. Operating the engine at
excessive speed can increase the hazard of personal
injury.
9. Never run a machine inside a closed area.
10.Mower blades are sharp and can cut your hands. Wrap
the blade(s) or wear gloves, and use extra caution
when servicing them.
11.Keep nuts and bolts, especially blade attachment
bolts, tight and keep equipment in good condition. On
multi-bladed mowers, take care as rotating one blade
can cause other blades to rotate.
12.Do not smoke when working around the battery.
Keep all sparks and flames away from battery. The
battery presents an explosion hazard because it gives
off hydrogen and oxygen...especially when
recharging.
13.Before "JUMP STARTING" a dead battery, read and
follow all of the instructions to help protect the
alternator from damage due to extreme load changes.
(See "JUMP STARTING" in "OPERATING THE
ENGINE" section.)
Batteries contain sulfuric acid and produce explosive
gases. Follow the instructions below to prevent
personal injury.
A Wear eye and skin protection.
A Keep sparks and flame away.
A Always have adequate ventilation while charging
or using the battery.
14.Keep first aid kit and fire extinguisher available at all
times.
15.Disconnect the battery's negative (-) cable before
working on or near electric components.
16.Do not use or charge the refillable type battery if the
fluid level is below the LOWER (lower limit level) mark.
Otherwise, the battery component parts may
prematurely deteriorate, which may shorten the
battery's service life or cause an explosion. Check the
fluid level regularly and add distilled water as required
so that the fluid level is between the UPPER and
LOWER levels.
17.To avoid sparks from an accidental short circuit,
always disconnect the battery's negative (-) cable first
and connect it last.
(1) Battery
(2) Positive cable (+)
(3) Negative cable (-)
18.Make sure cir-clips, nuts and spring lock washers are
properly secured on the front and rear wheels,
respectively.
19.Never tamper with safety devices.
Check their proper operation regularly.
20.Check brake operation frequently. Adjust and service
as required.
21.Properly dispose of used lubricants, filters, batteries,
and other such components.
22.Do not attempt to mount a tire on a rim. This should be
done by a qualified person with the proper equipment.
5SAFE OPERATION
23.Always maintain the correct tire inflation pressure. Do
not inflate tires above the recommended pressure
shown in the Operator's Manual.
24.Securely support the machine when changing wheels.
25.Make sure that wheel bolts have been tightened to the
specified torque.
26.Escaping hydraulic fluid under pressure has sufficient
force to penetrate the skin causing serious personal
injury. Before disconnecting lines, be sure to relieve all
pressure. Before applying pressure to the system,
make sure all connections are tight and that lines,
pipes, and hoses are not damaged.
27.Fluid escaping from pinholes may be invisible. Use a
piece of cardboard or wood to search for suspected
leaks: do not use hands. Use safety goggles or other
eye protection.
If injured by escaping fluid, see a medical doctor at
once. Serious infection or reaction will result if proper
medical treatment is not administered immediately.
This fluid can produce gangrene or severe allergic
reaction.
(1) Cardboard
(2) Hydraulic line
(3) Magnifying glass
28.Waste products such as used oil, fuel, hydraulic fluid,
and batteries, can harm the environment, people, pets
and wildlife. Please dispose of properly.
29.Do not use beverage containers for waste fluids or
other products. Someone, particularly children, may
drink them by mistake.
30.See your local Recycling Center or KUBOTA Dealer to
learn how to recycle or get rid of waste products.
A A Material Safety Data Sheet (MSDS) provides
specific details on chemical products; physical and
health hazards, safety procedures, and emergency
response techniques. The seller of the chemical
products used with your machine is responsible for
providing the MSDS for that product upon request.
