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 and understand 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 understand the
contents, it is the owner's responsibility to explain this
material to them. This mowing machine is capable of
amputating hands, feet and throwing objects. Failure to
observe the following safety instructions could result in
serious injury or death.
BEFORE OPERATING THE
MACHINE
Know your equipment and its limitations. Read all
instructions in this manual before attempting to start
and operate the machine.
1. General
• 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 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 operator's
manual before operating the machine. Practice
operating the machine at low engine speed in an
unobstructed area without engaging the mower.
• Pay special attention to the safety labels on the
machine itself.
• Do not operate the machine or any attachments
while under the influence of alcohol, medication,
controlled substances or when fatigued.
• Do not wear loose, torn, or bulky clothing around
the machine. The clothing may catch on moving
parts or controls, leading to the risk of an accident.
Wear and use any additional safety items such as a
hard hat, safety boots or shoes, eye and hearing
protection, gloves and so on, as appropriate or
required.
• Do not wear radio or music headphones while
operating the machine.
• Do not operate the machine or any attachments
while using or texting with a cellphone or any other
electronic device.
Safe operation requires your full attention.
• Carefully check the vicinity before operating
machine or any implement attached to it. Clear the
work area of objects (such as wires and rocks,) that
might be picked up and thrown. Check for overhead
clearance which may interfere with a grass catcher.
• Check parking brake and other mechanical parts for
correct adjustment and wear. Replace worn or
damaged parts promptly. Check the tightness of all
nuts and bolts regularly.
(See PERIODIC SERVICE on page 49 and
ADJUSTMENT on page 78.)
• Keep all shields and guards in place. Replace any
that are damaged or missing. Do not operate
unless they are functioning properly.
• Before allowing other people to use your machine,
explain how to operate and have them read this
manual before operation.
• Do not allow any bystanders around or near
machine during operation.
• 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.
• 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 the equipment.
• 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.
• Do not modify the machine. Unauthorized
modification may affect the function of the machine,
which may result in personal injury.
• Use only implements approved by KUBOTA. Use
proper ballast on the front or rear of the machine to
reduce the risk of upsets. Follow the safe operating
procedures specified in the manuals of the
equipment.
• Keep your machine clean. Accumulations of dirt,
grease, and trash can contribute to fires and lead to
personal injury.
• The exhaust gas from the muffler is very hot. To
prevent fire, do not expose dry grass, mowed
SAFE OPERATION
ZG327A-AU
5

grass, oil and any other combustible materials to
the exhaust gas. Use a spark arrester where
required. Keep the engine and muffler clean all the
times.
2. ROPS
• The ROPS is an integral and effective safety
device.
• KUBOTA recommends the use of a roll-over
protective structure (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.
• 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
foldable ROPS in areas where there are slopes,
drop-offs or water.
• Check carefully for overhead clearances (such as
branches, doorways and electrical wires) before
driving under any objects and do not contact them.
• Keep the ROPS in safe operating condition by
periodically and thoroughly inspecting for damage
and keeping all mounting fasteners tight.
• 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. Be certain that the
seat belt can be released quickly in the event of an
emergency.
(1) ROPS
(2) Seat belt
OPERATING THE MACHINE
1. Starting to operate the machine
• Always sit in the operator's seat when starting the
engine or operating levers or controls.
• Before starting the engine make sure that the
motion control levers are in neutral lock, the parking
brake is applied, hood is closed and the power
take-off (PTO) is disengaged (OFF).
• Do not start the engine by shorting across starter
terminals. The machine may start in gear and move
if the normal starting circuitry is bypassed.
• Do not operate or idle the engine in a non-
ventilated area. Carbon monoxide gas is colorless,
odorless, and deadly.
• Do not start the engine while tilting deck.
• Check before each use that the operator presence
control (OPC) system is functioning correctly.
Test the safety systems.
(See Checking the engine start system on page
56 and Checking the OPC system on page 57.)
Do not operate unless they are functioning
correctly.
• Check all fluids before starting.
2. Working the machine
• Do not turn sharply when driving at high speed.
• To avoid tip-over accidents, slow down when
turning on uneven terrain or before stopping.
• Do not operate near ditches, holes, embankments,
or other terrain, which may collapse under the
machine's weight. The risk of machine tip-overs
increases when the ground is loose or wet.
• Park the machine on a firm and level surface.
Before you get off, apply the 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.
SAFE OPERATION
6
ZG327A-AU

• 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, and so on).
• Know what is behind you before backing up. Look
to the rear before and when backing. Do not mow
while in reverse. Operate in reverse with the blades
engaged only when absolutely necessary and make
sure the area immediately behind you is clear of
obstructions or holes, and small children.
• When working in groups, always let others know
what you are doing ahead of time.
• Do not drive the machine on streets or highways.
Watch for traffic when you cross roads or operate
near roads.
• Be aware of the mower discharge direction and do
not point it at anyone.
Never operate with the discharge deflector raised,
removed or altered.
• When using any attachments, never direct
discharge material toward bystanders. Do not allow
people or pets near the attachments while in
operation.
Do not mow when bystanders are present in the
mowing area.
• To reduce fire hazards, keep the engine exhaust
area free of grass or leaves.
• Be sure that the rotating blades and the engine are
stopped and the key is removed before placing
hands or feet near blades, cleaning blockages or
unclogging the discharge deflector.
• Keep hands and feet away from the cutting units.
Shut the engine off and wait for all movement to
stop before removing the grass catcher or
unclogging the discharge deflector.
• Watch the temperature gauge and maintain all
screens to avoid overheating conditions.
• Always inspect the mower for damage after striking
a foreign object. Repair or replace any damaged
parts before restarting.
• Operate during daylight or in bright artificial light.
• Never raise the deck with the blades running.
Disengage the PTO and stop the blades from
rotating if not mowing.
3. Safety for children
Tragic accidents can occur if the operator is not alert of
the presence of children. Children are attracted to the
machine and mowing activity.
• Never assume that children will remain where you
last saw them.
• Keep children out of the mowing area and under
the watchful care of another responsible adult.
• Be alert and turn the machine off if children enter
the area.
• Before and when backing, look behind and down
for small children.
• 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.
• Never allow children to operate the machine, even
under adult supervision.
• Use extra care when approaching blind corners,
shrubs, trees, or other obstructions that might hide
children from sight.
• Do not mow in reverse. Operate in reverse with the
blades engaged only when it is absolutely
necessary and make sure that the area to the rear
is clear of children before doing so.
4. Operators, age 60 years and older
Data indicates that operators, age 60 years and older,
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.
5. Operating on slopes
Slopes are a 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
runaway.
Do
• To avoid tip-over accidents, operate across slopes,
not up and down. Stay off hills and slopes too steep
for safe operation.
• Remove obstacles such as rocks and tree limbs,
and so on.
• 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.
• Follow the manufacturer's recommendations for
wheel weight or counterweights to improve stability.
• Keep all movement on slopes slow and gradual. Do
not make sudden changes in speed or direction.
• Avoid starting or stopping on a slope. If tires lose
traction, disengage the PTO and proceed slowly
straight down the slope.
• Reduce the speed and exercise extreme caution on
slopes and in sharp turns to prevent tip-over
accidents or loss of control.
• Use special caution when changing direction on
slopes. Slow down, and use extra caution when
changing direction on a slope.
SAFE OPERATION
ZG327A-AU
7

Do not
• Do not turn on slopes unless necessary. If
necessary, turn uphill slowly and gradually.
• 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.
• Do not mow on wet grass. Reduced traction could
cause sliding and loss of control.
• Do not try to stabilize the machine by putting your
foot on the ground.
• Do not use grass catcher on steep slopes.
• Do not start or stop suddenly when going uphill or
downhill. Avoid sudden start and stops on slopes.
• Never “freewheel”. Do not let the machine travel
downhill with motion control levers at the neutral
lock position or in neutral.
• Do not operate the machine without the mower
deck installed.
6. Stopping the machine
• Park the machine on level ground.
• Make sure that the machine and all attachments
have come to a complete stop before you get off.
• Before you get off, apply the 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.
• Do not park the machine on dry grass or leaves.
7. Using the PTO
• Before installing or using PTO-driven equipment,
read the manufacturer's manual and review the
safety labels attached to the equipment.
• Wait until all moving components have completely
stopped before connecting, disconnecting,
adjusting, cleaning, or servicing any PTO-driven
equipment.
• Use the PTO with KUBOTA approved attachments.
The speed of PTO:
ZG327A-AU: 2530 rpm at 3200 engine rpm

SERVICING AND STORAGE
1. Servicing the machine
• Before servicing, park the machine on a firm, level
surface and apply the parking brake. Remove the
key to prevent an accidental start-up.
• Allow the machine time to cool before touching the
engine, muffler, radiator and so on.
• Always stop the engine before refueling. Avoid
spills and overfilling. If fuel is spilled, do not attempt
to start the engine and avoid creating any source of
ignition until fuel vapors have dissipated.
(1) Fuel tank cap
• Use extra care when handling gasoline fuels. They
are flammable.
1. Use only an approved container.
2. Do not remove the fuel cap or refuel with the
engine running. Allow the 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.
• 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.

• Before “jump starting” a dead battery, read and
observe all of the instructions.
• Disconnect the battery or remove the spark plug
wire before making any repairs.
Disconnect the negative terminal first and the
positive last. Reconnect the positive first and
negative last. Wear protective clothing and use
insulated tools.
• 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.
• Keep a first aid kit and fire extinguisher handy at all
times.
• 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 the machine.
• Always maintain the correct tire inflation pressure.
Do not inflate tires above the recommended
pressure shown in the operator's manual.
• Provide adequate support when changing wheels.
• Make sure that wheel nuts and bolts have been
tightened to the specified torque.
• 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.

• 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.

(2) Hydraulic line
(3) Magnifying glass
• Do not make adjustments or repairs with the engine
running.
• Keep the machine free of grass, leaves, or other
debris build-up.
• Do not change the engine governor setting or
overspeed the engine.
• Do not run the machine inside a closed area.
• Mower blades are sharp and can cut your hands.
Wrap the blade(s) or wear gloves, and use extra
caution when servicing them.
• Keep nuts and bolts, especially blade attachment
bolts, tight and keep equipment in good condition.
• Never tamper with safety devices. Check their
operation for proper function regularly.
• Waste products such as used oil, fuel, coolant,
brake fluid, and batteries can harm the
environment, people, pets and wildlife. Please
dispose of the waste products properly.
• Do not use beverage containers for waste fluids or
other products. Someone, particularly children, may
drink them by mistake.
• Securely support the machine or any machine
elements with stands or suitable blocking before
working underneath. For your safety, do not rely on
hydraulically supported devices as they may leak
down, suddenly drop or be accidently lowered.
• Consult your local recycling center or KUBOTA
Dealer to learn how to recycle or get rid of waste
products.
– 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.
2. Storage
• 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.
• To avoid sparks from an accidental short circuit,
always disconnect the battery's ground cable (-)
first and reconnect it last.
(1) Battery
(2) Ground cable
(+) Positive terminal
(-) Negative terminal
• To avoid the danger of exhaust fume poisoning, do
not operate the engine indoors without adequate
ventilation.
• To reduce fire hazards, clean the machine
thoroughly before storage. Dry grass and leaves
around the engine and muffler may ignite.
