SAFETY INSTRUCTIONS
BEFORE SERVICING AND REPAIRING
• Read all instructions and safety instructions in this
manual and on your machine safety decals.
• Clean the work area and machine.
• Park the machine on a firm and level ground, and set
the parking brake.
• Lower the implement to the ground.
• Stop the engine, and remove the key.
• Disconnect the battery negative cable.
• Hang a “DO NOT OPERATE” tag in operator
station.
SAFETY FIRST
This symbol, the industry’s “Safety Alert Symbol”, is used throughout this manual and on labels on
the machine itself to warn of the possibility of personal injury. Read these instructions carefully.
It is essential that you read the instructions and safety regulations before you attempt to repair or use
this unit.
DANGER : Indicates an imminently hazardous situation which, if not avoided, will result in
death or serious injury.
WARNING : Indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
CAUTION : Indicates a potentially hazardous situation which, if not avoided, may result in
minor or moderate injury.
QIMPORTANT : Indicates that equipment or property damage could result if instructions are not
followed.
QNOTE : Gives helpful information.

M9540Low Profile, WSM SAFETY INSTRUCTIONS
SAFETY STARTING
• Do not start the engine by shorting across starter
terminals or bypassing the safety start switch.
• Do not alter or remove any part of machine safety
system.
• Before starting the engine, make sure that all shift
levers are in neutral positions or in disengaged
positions.
• Never start the engine while standing on ground.
Start the engine only from operator’s seat.
SAFETY WORKING
• Do not work on the machine while under the influence
of alcohol, medication, or other substances or while
fatigued.
• Wear close fitting clothing and safety equipment
appropriate to the job.
• Use tools appropriate to the work. Makeshift tools,
parts, and procedures are not recommended.
• When servicing is performed together by two or more
persons, take care to perform all work safely.
• Do not work under the machine that is supported
solely by a jack. Always support the machine by
safety stands.
• Do not touch the rotating or hot parts while the engine
is running.
• Never remove the radiator cap while the engine is
running, or immediately after stopping. Otherwise, hot
water will spout out from radiator. Only remove
radiator cap when cool enough to touch with bare
hands. Slowly loosen the cap to first stop to relieve
pressure before removing completely.
• Escaping fluid (fuel or hydraulic oil) under pressure
can penetrate the skin causing serious injury. Relieve
pressure before disconnecting hydraulic or fuel lines.
Tighten all connections before applying pressure.
• Do not open high-pressure fuel system.
High-pressure fluid remaining in fuel lines can cause
serious injury. Do not disconnect or attempt repair
fuel lines, sensors, or any other components between
the high-pressure fuel pump and injectors on engines
with high pressure common rail fuel system.
• High voltage exceeding 100 V is generated in the
ECU, and is applied to the injector.
Pay sufficient caution to electric shock when
performing work activities.

M9540Low Profile, WSM SAFETY INSTRUCTIONS
AVOID FIRES
• Fuel is extremely flammable and explosive under
certain conditions. Do not smoke or allow flames or
sparks in your working area.
• To avoid sparks from an accidental short circuit,
always disconnect the battery negative cable first and
connect it last.
• Battery gas can explode. Keep sparks and open
flame away from the top of battery, especially when
charging the battery.
• Make sure that no fuel has been spilled on the engine.
VENTILATE WORK AREA
• If the engine must be running to do some work, make
sure the area is well ventilated. Never run the engine
in a closed area. The exhaust gas contains poisonous
carbon monoxide.
PREVENT ACID BURNS
• Sulfuric acid in battery electrolyte is poisonous. It is
strong enough to burn skin, clothing and cause
blindness if splashed into eyes. Keep electrolyte
away from eyes, hands and clothing. If you spill
electrolyte on yourself, flush with water, and get
medical attention immediately.
DISPOSE OF FLUIDS PROPERLY
• Do not pour fluids into the ground, down a drain, or
into a stream, pond, or lake. Observe relevant
environmental protection regulations when disposing
of oil, fuel, coolant, electrolyte and other harmful
waste.
KiSC issued 09, 2008 A

PREPARE FOR EMERGENCIES
• Keep a first aid kit and fire extinguisher handy at all
times.
• Keep emergency numbers for doctors, ambulance
service, hospital and fire department near your
telephone.

1. TIRES
WARNING
• Do not attempt to mount a tire on a rim. This should be done by a qualified person with the proper
equipment.
• Always maintain the correct tire pressureìo not inflate tires above the recommended pressure shown in
the operator’s manual.
IMPORTANTQ
• Do not use tires other than those approved by KUBOTA.
• Dual tires are not approved.
NOTEQ
• When optional different-diameter tires are fitted on the machine, the travel speed display mode must be
changed. Otherwise the travel speed will not get correctly displayed. Such mode switching is also needed
when the original tires are back on the machine. (Refer to “4. CHECKING AND ADJUSTING” at “L9.
ELECTRICAL SYSTEM” section in this manual.)
[1] TIRE SIZE AND INFLATION PRESSURE
IMPORTANTQ
• Excessive wear of tires may occur due to improper gear ratio.
Through the tire pressure is factory-set to the prescribed level, it
naturally drops slowly in the course of time. Thus, check it every day
and inflate as necessary.
QRecommended Inflation Pressure
• Maintain the pressure shown below for normal use.
NOTEQ
• Maintain the maximum pressure in front tires, if using a front
loader of when equipped with lots of front weight.
W1027488
[2] TREAD ADJUSTMENT
CAUTION
• When working on slopes or when working with trailer, set the wheel tread as wide as practical for maximum
stability.
• Support tractor securely on stands before removing a wheel.
• Do not work under any hydraulically supported devices. They can settle, suddenly leak down, or be
accidentally lowered. If necessary to work under tractor or any machine elements for servicing or
adjustment, securely support them with stands or suitable blocking beforehand.
• Never operate tractor with a loose rim, wheel, or axle.

(1) Front Wheels
Front tread width can be adjusted as shown with the standard
equipped tires.
To change the tread width
1. Remove the wheel rim and disc mounting bolts.
2. Change the position of the rim and disc (right and left) to the
desired position, and tighten the bolts.
3. Adjust the toe-in. (Refer to “[5] CHECK POINTS OF EVERY
200 HOURS” at “7. CHECK AND MAINTENANCE”.)
IMPORTANTQ
• Always attach wheels as shown in the figure.
• If not attached as illustrated, transmission parts may be
damaged.
• When re-fitting or adjusting a wheel, tighten the bolts to the
following torques then recheck after driving the tractor 200
m (200 yards) and thereafter according to service interval.
(Refer to “[5] CHECK POINTS OF EVERY 50 HOURS” at
“7. CHECK AND MAINTENANCE”.)
NOTEQ
• Wheels with beveled or tapered holes: use the tapered side
of lug nut.

[3] TIRE LIQUID INJECTION
Auxiliary weights can be used to increase traction force for plowing in fields or clayey ground.
Another way is to inject water or another liquid, such as a calcium chloride solution in the tires. Water must not be
used in winter since it freezes at 0 °C (32 °F). The calcium chloride solution will not freeze and moreover, affords
higher effect than water since its specific gravity is higher than that of water by about 20 %. Below is an explanation
of calcium chloride solution injection.
IMPORTANTQ
• Do not fill the front tires with liquid.
Injection
CAUTION
• When a calcium chloride solution is used, cool it before
pouring it into the tire.
• Do not fill tires with water or solution more than 75 % of full
capacity (to the valve stem level).
The following four ways can be used to inject water or a calcium
chloride solution into tires.
1. Gravity injection (Fig. 1)
2. Pump injection (Fig. 2)
3. Pressure tank injection (Fig. 3)
4. Injection directly from tap (only when water is being used).
NOTEQ
• Once injection is completed, reset the air valve, and pump
air into the tire to the specified pressure.
