SAFE OPERATION
1
Careful operation is your best insurance against an accident. Read this section carefully before operating the machine. All operators, whether experienced or not, should read this and other related manuals before operating the mower or any attachment on 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.
1. BEFORE OPERATING
(1) Know your equipment and its limitations. Read this
entire manual before attempting to start and operate
the machine. (2) Know the controls and how to stop quickly. (3) Pay special attention to the warning, caution and
danger labels on the machine itself. (4) KUBOTA recommends the use of a ROPS (Roll Over
Protective Structure) and seat belt in almost all
applications. This combination will reduce the risk
of serious injury or death should the machine tip
over.
Thismachineisintendedtouseonatterrain.
(1) Seat belt (2) ROPS
(5) Always use the seat belt if the machine has a ROPS.
Never fasten the seat belt without a ROPS. Check the
seat belt daily and replace if frayed or damaged. (6) Never modify or repair a ROPS. Welding, bending,
drilling or cutting any portion of the ROPS will
weaken the ROPS structure. If any structural
member is damaged, replace the entire structure at
your local KUBOTA dealer.
(7) Do not operate the machine or any attachments
while under the inuence of alcohol, medication,
controlled substances or when fatigued.
(8) Check brakes, clutch, 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 MAINTENANCE AND ADJUSTMENTS section.)
(9) Keep all shields and guards in place. Replace any
that are damaged or missing.
(10) Carefully check the vicinity before operating the
machine or any attachments to it. Clear the work area of objects (wires, rocks, etc.) that might be picked up and thrown. Do not allow any bystanders around or near machine during operation.
(11) Before allowing other people to use your machine,
explain how to operate and have them read this manual before operation.
(12) Never wear loose, torn, or bulky clothing around
machine. The clothing may catch on moving parts or controls. 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.
(13) Neverallowpassengers ornon-qualiedoperators
on the machine at any time. You must operate the machine from the seat only.
(14) Keep your machine clean. Accumulations of dirt,
grease,andtrashcancontributetoresandleadto
personal injury.
(15) In addition to the design and conguration of
equipment, hazard control and accident prevention are dependent upon the awareness, concern, and prudence of personnel involved in the operation, transport, maintenance, and storage of equipment or in the use and maintenance of facilities.
(16) 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,speciedinthemanuals
included with equipment.
(17) Follow the maintenance recommendations. See
"Maintenance and Lubrication".
(18) It is recommended that your machine be thoroughly
inspected at least once a year by an authorized KUBOTA Dealer.
(19) This machine is equipped with many safety devices.
Do not attempt to remove or alter them.
(20) The exhaust gas from the mufer is very hot. To
preventre,donotexposedrygrass,mowedgrass,
oil or any other combustible materials to exhaust gas. Use a spark arrester where required. Also keep
Page 6
2
the engine and mufer clean all the time. Replace
themuferifithasafault.
(21) While mowing, always wear substantial foot wear
and long trousers. Do not operate the equipment
when barefoot or wearing open sandals. (22) Do not wear radio or music headphones while
operating the machine. Safe operation requires your
full attention. (23) Keep the machine and attachments in good operating
condition and keep safety devices in place and in
proper working condition. (24) Do not modify the machine. Unauthorized
modicationmayaffectthefunctionofthemachine,
which may result in personal injury. (25) 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 1 blade can cause
other blades to rotate.
2. OPERATING
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 all
levers and speed control pedal are in neutral, the
parking brake is engaged, and Power Take Off is
disengaged. (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 "ride" the brake pedal. Use brake for stopping
only.
Operating
(1) Keep all shields and guards in place. Replace any
that are damaged or missing. (2) Do not drive at high speed or turn the machine when
the differential is locked. (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) To avoid tip over, operate up and down slopes, not
across. Avoid sudden starts and stops on slopes.
Slow down, and use extra caution when changing
directions on a slope.
Parkthemachineonarm,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) When working in cooperation with other operators,
always let others know what you are doing ahead of
time. (7) Never try to mount or dismount a moving machine. (8) Do not operate the machine with bare feet. Keep
hands, feet, and clothing away from power-driven
parts. (9) Do not drive machine on streets or highways. Watch
for trafc when you cross roads or operate near
roads. (10) Look to the rear before and when backing. You
must disengage blades before shifting into reverse.
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. (11) Do not cross gravel roads with the PTO engaged. (12) Do not drive at high speed or turn the front mower
when the differential is locked. (2WD) (13) Do not depress 4WD release pedal on slopes. (4WD) (14) Be aware of the mower discharge direction and do
not point it at anyone. (15) 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.
(16) To reduce re hazards, keep the engine exhaust
area free of grass or leaves. (17) Be sure rotating blades and engine are stopped and
the key is removed before placing hands or feet
near blades. (18) Shut the engine off and wait for all movement to stop
before unclogging the chute of the grass catcher. [if
equipped] (19) Always inspect the mower and the grass catcher [if
equipped] 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 re-
starting.
(20) Operateduringdaylightorinbrightarticiallight.
(21) 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. (22) Stop the blades rotating before crossing surface
other than grass. (23) 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. (24) 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.

Operation 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. The control of a ride-on machine sliding on a slope will not be regained by the application of the brake.
Do not lift the grass container on a slope.
•
DO
(1) To avoid tip over, operate up and down slowly, not
across. 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 KUBOTA's recommendations for wheel
weights or counterweights to improve stability. (5) The weight of grass in the grass container may
increase the possibility of tip over. [if equipped] (6) Keep all movement on slopes slow and gradual. Do
not make sudden changes in speed or direction. (7) Avoid starting or stopping on a slope. If tires lose
traction, disengage the blades and proceed slowly
straight down the slope. (8) Reduce speed and exercise extreme caution on
slopes and in sharp turns to prevent tip-over or loss
of control. (9) Use special caution when changing direction on
slopes. (10) Shift "High - Low Gear Shift Lever" to the Low
position when mowing or operating 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
14°. (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 use the grass catcher on steep slopes. [if
equipped] (7) Do not stop or start suddenly when going uphill or
downhill. (8) Never "freewheel". Do not let the machine travel
downhill with speed control pedal at neutral
position.
(9) Do not use the trailer and the towing implement.
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.
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.
Stopping (1) Make sure that the machine has come to a complete
stop before dismounting.
(2) Before dismounting, disengage the PTO, lower all
attachments, place all control levers in their neutral positions, apply parking brake, turn off the engine, and remove the key switch.
(3) Make sure that the machine and all attachments
have come to a complete stop before dismounting.
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.

(1) Check the coolant level should be between the Low and
High mark. If the level is below the Low mark, remove the recovery tank cap, and add clean water and anti­freeze.
IMPORTANT:
Do not start engine without coolant. When mixing the anti-freeze with water, the anti-freeze mixing ratio is 50 %. Use clean, fresh water and anti-freeze to ll the radiator and recovery tank. Securely tighten the radiator cap and recovery tank cap.
(2) If the engine is stopped by over-load during operation, in
order for coolant to return from the recovery tank to the radiator, keep the engine rpm idle a little while.
(3) Remove the radiator pressure cap and check to see
that the coolant level is just below the port. If short, add coolant.
(4) To drain the used coolant, open the drain valves and
remove radiator cap. The radiator cap must be removed to completely drain the radiator.

Precaution at Overheating
Take the following actions in the event the coolant temperature be nearly or more than the boiling point, what is called "Overheating". (1) Stop the machine operation in a safe place and keep the
engine unloaded idling.
(2) Don't stop the engine suddenly, but stop it after about 5
minutes of unloaded idling.
(3) Keep yourself well away from the machine for further 10
minutes or while the steam blown out.
(4) Checking that there gets no danger such as burn, get rid
of the causes of overheating according to the manual, see "Troubleshooting" section. And then, start again the engine.
Always use a 50/50 mix of long-life coolant and clean soft water in KUBOTA engines. Consult your local KUBOTA dealer concerning coolant for extreme conditions.
(1) Long-life coolant (hereafter LLC) comes in several
types. Use ethylene glycol (EG) type for this engine.
(2) Before employing LLC-mixed cooling water, ll the
radiator with fresh water and empty it again. Repeat this
procedure 2 or 3 times to clean up the inside. (3) Mixing the LLC Premix 50% LLC with 50% clean soft water. When
mixing, stir it up well, and then ll into the radiator.
(4) The procedure for the mixing of water and anti-freeze
differs according to the make of the anti-freeze and the
ambient temperature. Refer to SAE J1034 standard,
more specically also to SAE J814c.
IMPORTANT:
When mixing the anti-freeze with water, the anti-freeze mixing ratio is 50 %.

pressure cap which permits the development of pressure within the cooling system.
(5) Adding the LLC
1. Add only water if the mixture reduces in amount by evaporation.
2. If there is a mixture leak, add the LLC of the same manufacturer and type in the same mixture percentage.
*Never add any long-life coolant of different
manufacturer. (Different brands may have different additive components, and the engine may fail to
perform as specied.)
(6) When the LLC is mixed, do not employ any radiator
cleaning agent. The LLC contains anti-corrosive agent. If mixed with the cleaning agent, sludge may build up, adversely affecting the engine parts.
(7) KUBOTA's genuine long-life coolant has a service life
of 2 years. Be sure to change the coolant every 2000 hours or every 2 years whichever comes faster.
NOTE:
The above data represent industry standards that necessitate a minimum glycol content in the concentrated anti-freeze.
Checking and Cleaning Radiator to
Prevent Overheating
Daily or after every 5 hours of operation, check to be sure the radiator screen and radiator core are clean. Dirt or chaff on the radiator screen or radiator core decrease cooling performance. (1) Remove the radiator screen and panel screen, and
remove all foreign material.
(2) Remove the dust from between the ns and the tube.
(3) Tighten the fan drive belt as necessary. For this, refer to
page 38.
(4) If scale forms in the tube, clean with the scale inhibitor
or its equivalent.
(5) Each time the panel screen is covered with grass during
operation, rub it off the screen with hand. Check the radiator screen from time to time if grass often gets on it.
(6) If the dust or chaff is accumulated inside of the panel,
remove the air intake screen and clean the inside of the panel completely.
After cleaning, place the air intake screen properly.

5. OPERATION
5.1 MAKING THE MOST OF YOUR
MOWER
(1) When using your mower for the rst time, choose
a smooth level area and cut in straight and slightly
overlapping strips. (2) The size and type of the area to be mowed will
determine the proper mowing pattern. Take into account
obstructions, such as trees, fences and buildings. To
keep grass cuttings off fences, sidewalks, etc., it is
advisable to go over the outside of the area to be mowed
several times in a clockwise direction. To mow the area
remaining, work in a counterclockwise direction so the
cuttings are dispersed onto the previously cut area. (3) Always keep the left side of the mower toward trees,
posts or other obstacles on the rst trip around the
obstacle. (4) Most lawns should be mowed to keep the grass
approximately 50 to 80 mm (2 to 3 in.) high. Best results
are obtained by cutting often and not too short. To keep
a green lawn, never mow more than one third of the
height of the grass or a maximum of 25 mm (1 in.) in one
mowing. For extremely tall grass, set the cutting height at
maximum height for the rst mowing, then reset to the
desired height and mow again. Allow the grass to grow
to 8 cm (3 in.), then cut off only the top inch. (5) On thick, springy grass or soft ground, the mower rollers
may sink into ground giving too low a cut. Adjust the cutting height to get the desired height of
cut. (6) For best appearance, grass should be cut in the
afternoon or evening when it is free of moisture.
5.2 CUTTING HEIGHT
DANGER
To avoid serious injury or death:
Never operate mower in transport position.
(1) Check the both front gauge wheel pressures daily and
inate as necessary to prevent uneven cutting height.
(See page 13)
(2) To set the cutting height, adjust the front gauge wheels,
lift rods. Cutting height can be adjusted from 25 to 102 mm (1.0 to 4 in.).
NOTE:
For easy adjusting of the lift rods, place a wooden block under the rear end of the mower deck before lowering the mower deck. Cutting height will change because of the ground condition.
(3) Lower the mower deck by pushing the hydraulic control
lever forward. This lowers the mower deck from the transport position to the operating position.
(4) Use the higher setting for mowing in a rough area or
when mowing high grass. Lower setting should be used only for smooth lawns where short grass is desired.
Page 61
5.3 OPERATING MOWER
DANGER
To avoid serious injury or death:
Do not operate the mower without discharge
deectorproperlyboltedinplace.
WARNING
To avoid serious injury or death:
Clear the work area of objects which might be picked up and thrown. Do not direct the opening of the deector at bystanders or animals. Ejected objects may cause injury. Plan your mowing carefully before starting operations. Keep bystanders and animals away from the mowing area. Be sure to disengage the front PTO clutch of the mower before starting the engine.
9
(1) Keep the engine running at full throttle for best results. Control travel speed by speed control pedal. (2) During heavy duty use, operate the machine at a slower
ground speed or go over the area twice. (3) Keep the mower deck and gauge wheels in the raised
position when the mower is not being used. (4) The mower will not cut cleanly if the ground speed is too
high or if the blade speed drops due to an overload.
NOTE:
To prevent the engine from overheating, keep the radiator and radiator net clean.
