SAFE OPERATION
Careful operation is your best insurance against an
accident. The owner/user can prevent and is responsible
for accidents or injuries occurring to themselves, other
people or property. Read and understand this manual
carefully before operating the machine. All operators, no
matter how much experience they may have had, must
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.
If the operator(s) or mechanic(s) cannot read English it is
the owner's responsibility to explain this material to them.
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. BEFORE OPERATING
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.
-1SAFE OPERATION
ENGLISH
4. The ROPS is an integral and effective safety device.
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 you must set
the ROPS in the upright and locked position and put on
the seat belt for all other operations.
DO NOT remove the ROPS.
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.
If any structural member of the ROPS is damaged,
replace the entire structure at your local KUBOTA
Dealer. Any alterations to a ROPS must be approved
by the manufacturer.
Check the area to be mowed and never fold down a
folding ROPS in areas where there are slopes, drop
offs or water.
Check carefully for overhead clearances (i.e.
branches, doorways, electrical wires) before driving
under any objects and do not contact them.
Keep the ROPS in safe operating condition by
periodically thoroughly inspecting for damage and
keeping all mounting fasteners tight.
(1) ROPS
(2) Seat belt
SAFE OPERATION-2
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
ENGLISH
frayed or damaged. Be certain that the seat belt can be
released quickly in the event of an emergency.
6. Do not operate the machine or any attachments while
under the influence of alcohol, medication, controlled
substances or when fatigued.
7. 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.
8. Do not wear radio or music headphones while
operating the machine.
Safe operation requires your full attention.
9. 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.
10.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.)
11.Keep all shields and guards in place. Replace any that
are damaged or missing. Do not operate unless they
are functioning properly.
12.Before allowing other people to use your machine,
explain how to operate and have them read this
manual before operation.
13.Do not allow any bystanders around or near machine
during operation.
14.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.
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, maintenance of facilities.
16.Evaluate the terrain to determine what accessories
and attachments are needed to properly and safely
perform the job. Keep the machine and attachments in
good operating condition and keep safety devices in
place and in proper working condition. Do not operate
unless they are functioning properly.
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 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 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.
2. OPERATING
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.
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, 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.
Never operate with the discharge deflector raised,
removed or altered, unless using a grass catcher.
-3SAFE OPERATION
10.When using any attachments, never direct discharge
material toward bystanders. Do not allow anyone and
pets 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.Keep hands and feet away from the cutting units. Shut
the engine off and wait for all movement to stop before
removing grass catcher or unclogging chute.
14.Always inspect the mower for damage after striking a
foreign object. Repair or replace any damaged parts
before restarting.
15.Operate during daylight or in bright artificial light.
16.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.
17.Do not operate the machine when there is a possibility
of lightning. Even if the machine is equipped with a
cabin, the operator is not protected from lightning.
18.Never raise the deck with the blades running.
Stop blades if not mowing.
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.
A Stopping distance increases with speed and weight of
towed load. Travel slowly and allow extra time and
distance to stop.
A Never allow children or others in or on towed
equipment.
A Use additional caution when turning or operating
under adverse surface conditions.
C Operation on slopes
Slopes are major factor related to loss-of-control and tipÂover 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.
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 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. 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.
7. Do not mow in reverse unless it is absolutely
necessary.
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 must evaluate their ability to
operate the machine safely enough to protect themselves
and others from serious injury.
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.
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.
If tires lose traction, disengage PTO and proceed
slowly straight down the slope.
6. Reduce speed and exercise extreme caution on
slopes and in sharp turns to prevent tip-over or loss of
control.
SAFE OPERATION-4
7. Use special caution when changing direction on
slopes. Slow down, and use extra caution when
changing direction on a slope.
ENGLISH
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 on slopes. If tires lose
traction, disengage PTO and proceed slowly straight
down the slope.
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 you get off.
3. Before you get off, 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.
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. Use extra care when loading or unloading the machine
into a trailer or truck. Use full width ramps for loading
machine into trailer or truck.
4. This machine is not allowed to be used on public
roads.
5. Shut off fuel while storing or transporting.
6. Tie the machine down securely using straps, chains,
cable, or ropes.
7. Both front and rear straps must be directed down and
outward from the machine.
6. SERVICING AND STORAGE
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.
3. USING THE PTO
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:
ZD1011 / ZD1021 Without mower: 2450 to 2550 rpm at
3200 engine rpm
4. USING THE LIFT LINK
1. Use lift link only with authorized attachments designed
for lift link usage.
(1) Fuel tank cap
4. 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. Do not smoke when working around battery or when
refueling. Extinguish all cigarettes, cigars, pipes, and
other sources of ignition. Keep all sparks and flames
away from battery and fuel tank.
Never fill containers inside a vehicle or on a truck or
trailer bed with a plastic liner.
Always place containers on the ground away from
your vehicle before filling.
Remove equipment from the truck or trailer and refuel
it on the ground.
If this is not possible, then refuel such equipment with
a portable container, rather than from a fuel dispenser
nozzle.
Keep the nozzle in contact with the rim of the fuel tank
or container opening at all times until fueling is
complete.
Do not use a nozzle lock open device.
If fuel is spilled on clothing, change clothing
immediately.
Replace fuel cap and tighten securely.
Charge batteries in an open well ventilated area, away
from spark and flames.
A battery, especially when charging, will give off
hydrogen and oxygen gases, which can explode and
cause serious personal injury.
Unplug charger before connecting or disconnecting
from battery.
6. Before "jump starting" a dead battery, read and follow
all the instructions.
7. Disconnect battery or remove spark plug wire before
making any repairs. Disconnect the negative terminal
first and the positive last. Reconnect positive first and
negative last. Wear protective clothing and use
insulated tools.
-5SAFE OPERATION
(1) Battery
(2) Ground cable
(+): Positive terminal
(-): Negative terminal
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.
ENGLISH
SAFE OPERATION-6
10.Do not remove the radiator cap while coolant is hot.
When cool, slowly rotate cap to the first stop and allow
sufficient time for excess pressure to escape before
ENGLISH
removing the cap completely. If the machine has a
coolant recovery tank, add coolant there instead of the
radiator.
11.Do not attempt to mount a tire on a rim unless qualified
to do so and all proper safety precautions are followed.
Never allow untrained personnel to service machine.
12.Always maintain the correct tire inflation pressure. Do
not inflate tires above the recommended pressure
shown in the Operator's Manual.
16.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 you get 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
13.Provide adequate support when changing wheels.
14.Make sure that wheel nuts and bolts have been
tightened to the specified torque.
15.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,
