1SAFE OPERATION

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 before attempting to start
and operate the machine.

3. Pay special attention to the danger, warning and
caution 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.

1. BEFORE OPERATING

(1) ROPS
(2) Seat belt

SAFE OPERATION2

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 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 "Safety Devices" in "EVERY 50 HOURS" in
"PERIODIC SERVICE" section.)
Do not operate unless they are functioning correctly.

C 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, near trees, and
other obstructions and hidden hazards.

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 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.

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.

2. OPERATING

3SAFE OPERATION

C 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 Operation on slopes

Slopes are 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.
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 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.

3. Use the PTO with KUBOTA approved attachments.

The speed of PTO:
ZG327A-AU 2530 rpm at 3200 engine rpm

1. Use lift link only with authorized attachments designed
for lift link usage.

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. Use extra care when loading or unloading the machine
into a trailer or truck.

SAFE OPERATION4

C Servicing

1. Before servicing, park the machine on a firm, level
surface and apply the parking brake. Remove the key
to prevent accidental start-up.

2. Allow the machine time to cool before touching the
engine, muffler, radiator, etc.

3. Always stop the engine before refueling. Avoid spills
and overfilling. Wipe up spilled fuel immediately.

4. Use extra care in handling gasoline 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. Do not smoke when working around battery or when
refueling. Keep all sparks and flames away from
battery and fuel tank.
A battery, especially when charging, will give off
hydrogen and oxygen gases, which can explode and
cause serious personal injury.

6. Before "jump starting" a dead battery, read and follow
all the instructions.

7. Disconnect the battery's ground cable before working
on or near electric components.

8. 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.

9. Keep first aid kit and fire extinguisher handy at all
times.

10.Do not attempt to mount a tire on a rim unless qualified
to do so and all proper safety precautions are followed.

11.Always maintain the correct tire inflation pressure. Do
not inflate tires above the recommended pressure
shown in the Operator's Manual.

12.Provide adequate support when changing wheels.

13.Make sure that wheel nuts and bolts have been
tightened to the specified torque.

14.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.

15.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.

running.

17.Keep machine free of grass, leaves, or other debris
build-up.

18.Do not change the engine governor setting or
overspeed the engine.

19.Do not run a machine inside a closed area.

20.Mower blades are sharp and can cut your hands. Wrap
the blade(s) or wear gloves, and use extra caution
when servicing them.

21.Keep nuts and bolts, especially blade attachment
bolts, tight and keep equipment in good condition.

22.Never tamper with safety devices. Check their
operation for proper function regularly.

23.Waste products such as used oil, fuel, coolant, brake
fluid, and batteries, can harm the environment, people,
pets and wildlife. Please dispose of properly.

24.Do not use beverage containers for waste fluids or
other products. Someone, particularly children, may
drink them by mistake.

25.Securely support machine or any machine elements
with stands or suitable blocking before working
underneath. For your safety do not rely on
hydraulically supported devices, they may leak down,
suddenly drop or be accidently lowered.

26.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.

C Storage

1. Keep the machine and supply of fuel in locked storage
and remove the ignition key to prevent children or
others from playing or tampering with them.

2. To avoid sparks from an accidental short circuit,
always disconnect the battery's ground cable (-) first
and reconnect it last.

3. To avoid the danger of exhaust fume poisoning, do not
operate the engine in a closed building without

OPERATING THE ENGINE12

BThrottle Lever and Choke Knob

Pulling the throttle lever backward decreases the engine
speed and pushing it forward increases the engine speed.

[For a Cold Engine]

Always pull the choke knob out to the "ON" position to
start the engine in cold conditions.

Gradually return the choke control to the "OFF" position
after the engine starts and warms up.

The engine/equipment may be operated during the warm­up period, but it may be necessary to leave the choke
partially on until the engine warms up.

[For a Warm Engine]

Always push the choke knob in to the "OFF" position after
the engine starts.

BKey Switch

A Do not use starting fluid or ether.
A To protect the battery and the starter, make sure that

the starter is not continuously turned for more than 10
seconds at a time.
If the engine does not start, allow 60 seconds cool
down period between starting attempts.

A If the starter does not turn the engine over, shut off the

starter immediately. Do not make further attempts to
start the engine until the condition is corrected. Do not
jump start using another battery.
Consult your local KUBOTA dealer.

A Do not turn the key switch to the "START" position

while the engine is running.

A When the temperature is below 0 (32 ), run the

engine at medium speed to warm up the lubricant of
the engine and the transmission for at least 10
minutes. If the machine is operated before the
lubricant is warm enough, the machine life will be
shortened.

A Do not operate the machine under full load until it is

sufficiently warmed up 2 or 3 minutes for temperature
above 0 (32 ).

A When the ambient temperature is less than -15

(5 ), remove the battery from the machine and store
it somewhere warm until the next operation.

speed.

13OPERATING THE ENGINE

CHECK DURING OPERATING

While operating, make the following checks to see that all
the parts are functioning normally.

BImmediately Stop the Engine if:

A The engine suddenly slows down or accelerates.
A Unusual noises are suddenly heard.
A Exhaust fumes suddenly become discolored.

BEasy Checker (TM)

If the warning lamps in the Easy Checker (TM) come on
during operation, stop the engine immediately, and find
the cause as shown below.
Never operate the machine while Easy Checker (TM)
lamp is "ON".

Engine oil pressure
If the oil pressure in the engine goes below the
prescribed level, the warning lamp in the Easy
Checker (TM) will come on.

If this should happen during operation, stop the
engine immediately and check level of engine oil.

BFuel Gauge

1. The fuel gauge shows the amount of fuel left in the LH
tank.

2. Refuel both the fuel tanks evenly.

3. If there is an amount gap between the LH and RH
tanks, the fuel in the bigger-amount tank will be
consumed first.
Fuel in both the tanks will be consumed at the same
time after the fuel levels of both the tanks become the
same.

A Fill the fuel tank only to bottom of the filler neck.
A Fill the fuel on a level ground.
A Be careful not to empty the fuel tank. Otherwise air

may enter the fuel system.
Should this happen, the system should be bled. (See
"Bleeding Fuel System" in "SERVICE AS REQUIRED"
in "PERIODIC SERVICE" section.)

A Only fill with gasoline containing less than 10%

ethanol content.

BFuel Pump

This fuel pump has a limit drive function.
