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) un der pressure
can penetrate the skin causing serious injury. Relieve
pressure before disconnecting hydraulic or fuel lines.
Tighten all connections before applying pressure.
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

CAUTION
• When using antifreeze, put on some protection such as
rubber gloves (Antifreeze contains position).
• If should drink antifreeze, throw up at once and take medic al
attention.
• When antifreeze comes in contact with the skin or clothing,
wash it off immediately.
• Do not mix different types of Antifreeze.
The mixture can produce chemical reaction c ausing harmful
substances.
• Antifreeze is extremely flammable and explosive under
certain conditions. Keep fire and children away from
antifreeze.
• When draining fluids from the engine, place some container
underneath the engine body.
• Do not pour waste onto the grounds, down a drain, or into
any water source.
• Also, observe the relevant environmental protection
regulations when disposing of antifreeze.
If it freezes, coolant can damage the cylinders and radiator. If the
ambient temperature falls below 0 °C or before a long-term storage,
let out cooling water completely, or mix fresh water with long-life
coolant and fill the radiator and reserve tank with the mixture.
1. Long-life coolant (he reafter LLC) comes in several types. Use
ethylene glycol (EG) type for this engine.
2. Before employing LL C-mixed cooli ng water, fill th e radiator with
fresh water and empty it again.
Repeat this procedure 2 or 3 times to clean up the inside.
3. Mixing the LLC
Put the LLC in coolin g water in the percentage (%) for a target
temperature. Wh en mixing, stir it up well, and then fill i nto the
radiator.
4. The procedure for the mixing of water and antifreeze differs
according to the make of the antifreeze and the ambient
temperature. Refer to SAE J1034 standard, more specifically
also to SAE J814c.
IMPORTANT
• When the antifreeze is mixed with water, the antifreeze
mixing ratio must be less than 50 %.

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
manufacture and type in the same mixture percentage.
*Never add any long-life coolant of different manufacture.
(Different brands may hav e different additive components, and
the engine may fail to perform as specified.)
6. When the LLC is mixed, do not employ any radiator cleaning
agent. The LLC contain s antico rrosive agen t. If mixed with the
cleaning agent, sludge may build up, adversely affecting the
engine parts.
7. Kubota's genuine l ong-life coolant has a servi ce life of 2 years.
Be sure to change the coolant every 2 years.
• The above data represents industry standards that

Bleeding Fuel System
Air must be removed:
1. When the fuel filter or lines are removed.
2. When water is drained from water separator.
3. When tank is completely empty.
4. After the tractor has not been used for a long period of time.
■ Bleeding procedure is as follows:
1. Fill the fuel tank with fuel, and open the fuel cock (1).
2. Pump the fuel pump kno b (2) locate d on the top of the fuel filter.
The fuel pump knob will pump easily at first and with added
resistance as a ir i s pu r ged from th e system. To m ake sur e ai r i s
completely purged, pi nc h th e fu el o ve rflow hos e ( 3) wi th fi ng ers,
if a pulsation is felt when the knob is pumped, then, no air
remains.
3. Set the hand th rottle lever at the maximum s peed position , turn
the key switch to start the engine, and then reset the throttle lever
at the mid speed (around 1500 rpm) position.
If engine doesn't start, try it several times at 30 second intervals.
4. Accelerate the engi ne to remo ve the small p ortion of air lef t in the
fuel system.
5. If air still remains and the engine stops, repeat the above steps.
• Do not hold key switch at engine start position for more than
10 seconds continuously. If more engine cranking is
needed, try again after 30 seconds.
1. The tractor is equipped with drain plug (1) under the clutch
housing.
2. After operatin g in rain, snow or tractor has been washed, water
may get into the clutch housing.
3. Remove the dr ain plug (1) and drain the wa ter, then install the
plug (1) again.

Bleeding Brake System
• While bleeding, make sure to keep enough brake oil in the
brake oil reservoir.
1. Disconnect the brake pipes (1) from the master cylinder.
2. Move the brake pedal up and down by han d. A t th is ti me, when
raising the pedal, close the master cylinder outlet by a finger, and
when lowering, release the finger.
Repeat this operation several times. (Prepare and oil can.)
3. After bleeding the master cylinder, install the front brake pipes.
4. After installing the vinyl pipe (3) to the bleeder (2) loosen the
bleeder two turns.
5. Move the brake pedal up and down.
Repeat this motion until air bubble in brake oil disappears.
After bleeding, tighten the bleeders firmly.

• If the air mixes in the brake hydraul ic circuit, poor or no br aking
force is obtained du e to compress the air even when the brake
pedal is pressed.
Accordingly whenever the hydraulic brake system is
disassembled, be sure to bleed after reassembling.

Replacing Fuse
1. The tractor electrical sy stem is pr otected fr om poten tial dam age
by fuses.
A blown fuse indicates that there is an overload or short
somewhere in the electrical system.
2. If any of the fuses should blow, repl ace with a new one of the
same capacity.
• Before replacing a blown fuse, determine why the fuse blew
and make any necessary repairs. Failure to follow this
procedure may result in serious damage to the tractor
electrical system. Refer to troubleshooting section of this
manual for specific information dealing with electrical
problems.
1. A shortage of refrigerant impairs the air conditioner performance.
Check the following poin ts. If it is indicated that the amount of
refrigerant is extremely low. Do to inspect and charge.
■ Checking procedure
1. Run the air-conditioner in the following conditions.
• Engine speed: About 1500 rpm
• Temperature control dial: Maximum cooling position (leftmost)
• Blower switch: Highest blow (HI)
• Air-conditioner switch: ON
2. Look into the sight glass to see if the refrigerant is flowing through
its circuit.
(Reference)
(A) Proper
: Little or no air bubbles in the refrigerant flow.
(B) Low
: Lots of air bubbles in the refrigerant flow (air bubbles or foam
passing continuously).

• Excessive wear of tires may occur due to improper gear ratio.
Through the tire pressur e is factory-set to the prescribed lev el, it
naturally drops slowly in the course of time. Thus, check it every day

[5]TIRE LIQUID INJECTION
Auxiliary weights can be used to increase traction force for plowing in fields or clayey grounds.
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 si nce it freezes at 0 °C (32 °F). The calcium chloride so lution will not fr eeze and mor eover, 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.
• Do not fill the front tires with liquid.
Preparation of Calcium Chloride Solution
CAUTION
• When making a calcium chloride solution, do not pour water
over calcium chloride since this results in chemical reaction
which will cause high temperature. Instead add a small
amount of calcium chloride to the water at a time until the
desired solution is achieved.

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).
• To avoid damage of transmission, do not use rear wheel
weights and liquid ballast at the same time.
The following four ways can be used to in jec t wate r or a calci um
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).
NOTE
• Once injection is complete d, reset the air valve, and pump
air into the tire to the specified pressure.
