ENGLISH
SAFE OPERATION
Careful operation is your best insurance against an
accident. Read and understand this manual carefully
before operating the machine. All operators, no matter
how much experience they may have had, should read
this and other related manuals before operating the
machine or any implement attached to it. It is the owner's
obligation to instruct all operators in safe operation.
This mowing 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.
1. The ZERO TURN MOWING MACHINE has different
steering characteristics than other machines with a
steering wheel and does not have a service brake
pedal (but, has a parking brake lock pedal that can be
used to stop the machine in an emergency. Normal
slowing down and stopping is done with the motion
control levers.). Read and understand the operators
manual before operating the machine. Practice
operating machine at low engine speed without mower
engaged in an unobstructed area.
2. Know your equipment and its limitations. Read all
instructions in this manual and machine safety labels
before attempting to start and operate the machine.
3. Pay special attention to the safety labels on the
machine itself.
4. KUBOTA recommends the use of a Roll Over
Protective Structures (ROPS) and seat belt in almost
all applications. This combination will reduce the risk
of serious injury or death, should the machine be
upset.
The machine is equipped with a Foldable ROPS,
which may be temporarily folded down only when
absolutely necessary for areas with height constraints.
(There is no operator protection provided by the ROPS
in the folded position. For operator safety the ROPS
should be placed in the upright and locked position
and the seat belt fastened for all other operations.)
If the ROPS is loosened or removed for any reason,
make sure that all parts are reinstalled correctly before
operating the machine.
Never modify or repair a ROPS because welding,
bending, drilling, grinding, or cutting may weaken the
structure.
A damaged ROPS structure must be replaced, not
repaired or revised.
If any structural member of the ROPS is damaged,
replace the entire structure at your local KUBOTA
Dealer.
5. Always use the seat belt when the ROPS is upright. Do
not use the seat belt if the ROPS is down or if there is
no ROPS. Check the seat belt regularly and replace if
frayed or damaged.
6. Do not allow any bystanders around or near machine
during operation.
7. Do not allow passengers, children or non-qualified
operators on the machine at any time. The operator
must remain in the machine seat throughout
operation.
8. Do not operate the machine or any attachments while
under the influence of alcohol, medication, controlled
substances or when fatigued.
9. Do not wear loose, torn, or bulky clothing around
machine. The clothing may catch on moving parts or
controls, leading to the risk of accident. Wear and use
any additional safety items such as hard hat, safety
boots or shoes, eye and hearing protection, gloves,
etc. as appropriate or required.
10.Do not wear radio or music headphones while
operating the machine.
Safe operation requires your full attention.
11.Carefully check the vicinity before operating machine
or any implement attached to it. Clear the work area of
objects (wires, rocks, etc.) that might be picked up and
thrown. Check for overhead clearance which may
interfere with a grass catcher.
12.Check brakes and other mechanical parts for correct
adjustment and wear. Replace worn or damaged parts
promptly. Check the tightness of all nuts and bolts
regularly. (For further details, see "PERIODIC
SERVICE" and "ADJUSTMENT" section.)
13.Keep all shields and guards in place. Replace any that
are damaged or missing.

(2) Seat belt
SAFE OPERATION-2
ENGLISH
14.Before allowing other people to use your machine,
explain how to operate and have them read this
manual before operation.
15.In addition to the design and configuration of
equipment, hazard control and accident prevention
are dependent upon the awareness, concern and
prudence of personnel involved in the operation,
transport and maintenance of the equipment.
16.Keep the machine and attachments in good operating
condition and keep safety devices in place and in
proper working condition.
17.Do not modify the machine. Unauthorized modification
may affect the function of the machine, which may
result in personal injury.
18.Use only implements approved 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 manuals with equipment.
19.Keep your machine clean. Accumulations of dirt,
grease, and trash can contribute to fires and lead to
personal injury.
20.The exhaust gas from the muffler is very hot. To
prevent fire, do not expose dry grass, mowed grass, oil
and any other combustible materials to exhaust gas.
Use a spark arrester where required. Also keep the
engine and muffler clean all the time.

C
C
CC Starting
1. Always sit in the operator's seat when starting engine
or operating levers or controls.
2. Before starting the engine make sure that the motion
control levers are in neutral lock, the parking brake is
applied, and Power Take Off (PTO) is disengaged
(OFF).
3. Do not start engine by shorting across starter
terminals. The machine may start in gear and move if
normal starting circuitry is bypassed.
4. Do not operate or idle engine in a non-ventilated area.
Carbon monoxide gas is colorless, odorless, and
deadly.
5. Do not start engine while tilting deck.
6. Check before each use that operator presence
controls are functioning correctly. Test safety systems.
(See "Checking Engine Start System" and "Checking
OPC System" in "EVERY 50 HOURS" in "PERIODIC
SERVICE" section.)
Do not operate unless they are functioning correctly.
C
C
C
CC Working
1. Do not turn sharply when driving at high speed.
2. To avoid tip over, slow down when turning on uneven
terrain or before stopping.
3. Do not operate near ditches, holes, embankments, or
other terrain, which may collapse under the machine
weight. The risk of machine tip over increases when
the ground is loose or wet.
4. Park the machine on a firm and level surface.
5. Watch where you are going at all times. Watch for and
avoid obstacles. Be alert at curbs, shrubs, near trees,
and other obstructions and hidden hazards. Obstacles
can damage machine (fuel hoses, wire harness etc.).
6. Know what is behind you before backing up. Look to
the rear before and when backing. Do not mow while
in reverse unless absolutely necessary and make sure
the area immediately behind you is clear of
obstructions or holes and small children. Use extra
caution when machine is equipped with Grass
Catcher. Your view to the rear is restricted.
7. When working in groups, always let others know what
you are doing ahead of time.
8. Do not drive machine on streets or highways. Watch
for traffic when you cross roads or operate near roads.
9. Be aware of the mower discharge direction and do not
point it at anyone.
10.When using any attachments, never direct discharge
material toward bystanders. Do not allow anyone near
the attachments while in operation.
Do not mow when bystanders are present in the
mowing area.
11.To reduce fire hazards, keep the engine exhaust area
free of grass or leaves.
12.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.
13.Shut the engine off and wait for all movement to stop
before removing grass catcher or unclogging chute.
14.Watch the temperature gauge and maintain all
screens to avoid overheating conditions.
15.Always inspect the mower for damage after striking a
foreign object. Repair or replace any damaged parts
before restarting.
16.Operate during daylight or in bright artificial light.
C
C
C
CC Children
Tragic accidents can occur if the operator is not alert to
the presence of children. Children are attracted to the
machine and 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 machine off if children enter the area.
3. Before and when backing, look behind and down for
small children.
4. Never carry children. There is no safe place for them
to ride. 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.
2. OPERATING
-3SAFE OPERATION
ENGLISH
6. Use extra care when approaching blind corners,
shrubs, trees, or other obstructions that might hide
children from sight.
7. Do not mow in reverse unless it is absolutely
necessary and make sure area to the rear is clear of
children before doing so.
C
C
C
CC Operators, age 60 years and above
Data indicates that operators, age 60 years and above,
are involved in a large percentage of machine-related
injuries. These operators should evaluate their ability to
operate the machine safely enough to protect themselves
and others from serious injury.
C
C
C
CC Operation on slopes
Slopes are major factor related to loss-of-control and tip-
over 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.
If the engine stops when operating on a slope apply the
parking brake immediately to prevent machine run away.
DO
1. To avoid tip over, operate across the slopes not up and
down. 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. Follow the manufacturer's recommendations for wheel
weight or counterweights to improve stability.
5. Keep all movement on the slopes slow and gradual.
Do not make sudden changes in speed or direction.
6. Avoid starting or stopping on a slope. If tires lose
traction, disengage PTO and proceed slowly straight
down the slope.
7. Reduce speed and exercise extreme caution on
slopes and in sharp turns to prevent tip-over or loss of
control.
8. Use special caution when changing direction on
slopes. Slow down, and use extra caution when
changing direction on a slope.
DO NOT
1. Do not turn on slopes unless necessary. If necessary,
turn uphill slowly and gradually.
2. Do not mow near drop-offs, ditches, or embankments.
The mower could suddenly turn over if a wheel is over
the edge of cliff or ditch, or if an edge caves in.
3. Do not mow on wet grass. Reduced traction could
cause sliding and loss of control.
4. Do not try to stabilize the machine by putting your foot
on the ground.
5. Do not use grass catcher on steep slopes.
6. Do not start or stop suddenly when going uphill or
downhill. Avoid sudden start and stops on slopes.
7. Never "freewheel". Do not let the machine travel
downhill with motion control levers at neutral lock
position or in neutral.
8. Do not operate machine without the mower deck
installed.
C
C
C
CC Stopping
1. Park the machine on level ground.
2. Make sure that the machine and all attachments have
come to a complete stop before dismounting.
3. Before dismounting, apply parking brake, place the
motion control levers in their neutral lock positions,
disengage the PTO, lower all attachments to the
ground, turn off the engine, and remove the key.
4. Do not park the machine on dry grass or leaves.
1. Before installing or using PTO-driven equipment, read
the manufacturer's manual and review the safety
labels attached to the equipment.
2. Wait until all moving components have completely
stopped before connecting, disconnecting, adjusting,
cleaning, or servicing any PTO-driven equipment.

BBHour Meter
This meter gives readings for the hours the machine has
been operated for.
AAs the hour meter works electrically, it starts to work
when the key switch is turned to "ON", regardless of
the engine running or not.
COLD WEATHER STARTING
If the ambient temperature is below 0 (32 ) and the
engine is very cold, start it in the following manner:
1. Pull the choke knob out.
2. Turn the key switch to the START (" ") position.
AOperate the starter 5 seconds.
AIf the engine does not start, wait 10 seconds.
ARepeat this procedure until the engine starts.
3. When the engine starts, release the key to the "ON"
(" ") position.
4. Place the throttle lever midway between the "SLOW"
and the "FAST" positions.
WARMING UP
To avoid personal injury:
ABe sure to apply the parking brake during
warm-up.
For 5 minutes after engine start-up, allow the engine to
warm up without applying any load. This is to allow oil to
reach every engine part. If load should be applied to the
engine without this warm-up period, the troubles such as
seizure, breakage or premature wear may develop.
B
B

BBWarm-up and Transmission Oil in the Low
Temperature Range
Hydraulic oil serves as transmission oil. In cold weather,
the oil may be cold with increased viscosity. This can
cause delayed oil circulation or abnormally low hydraulic
pressure for some time after engine start-up. This in turn
can result in a trouble in the hydraulic system or a damage
to the hydraulic clutch.
To prevent the above, observe the following instructions:
Warm up the engine at about 50% of rated rpm according
to the table below:
ADo not operate unless the engine is well warmed up. If
operation is attempted while the engine is still cold, the
hydraulic mechanism will not function properly and its
service life will be shortened.
AIf noises are heard after the hydraulic control lever has
been activated and the implement is lifting, the
hydraulic mechanism is not adjusted properly. Unless
corrected, the unit will be damaged. Contact your local
KUBOTA Dealer for adjustment.

BBChecking Amount of Fuel and Refueling
To avoid personal injury:
AHandle fuel carefully. If the engine is running,
do not fill the fuel tank. If engine is hot, let
engine cool several minutes before adding fuel.
Do not smoke while filling the fuel tank or
servicing the fuel system. Fill fuel tank only to
bottom of filler neck. Do not fill completely full.
The empty space in the tank allows gasoline to
expand, when it heats up. Never remove the
fuel tank cap or add fuel when the fuel tank is
hot.
Check the fuel level. Take care that the fuel tank does not
become empty.
ADo not mix oil with gasoline.
ATighten the fuel cap until it clicks.
ADo not use the fuel cap other than KUBOTA approved
one.
ADo not permit dirt or trash or water to get into the fuel
system.
ABe careful not to let the fuel tank become empty,
otherwise air will enter the fuel system, necessitating
bleeding before next engine start.
ABe careful not to spill fuel during refueling. If a spill
should occur, wipe it off at once, or it may cause a fire.
Use only unleaded gasoline with an octane rating index of
87 or higher may be used.
AUse fuel within approximately 30 days after purchase
to avoid deterioration in fuel quality, or add fuel
