SAFE OPERATION

-1SAFE OPERATION

Careful operation is your best insurance against an
accident.

Read and understand this manual carefully before
operating the tractor.

All operators, no matter how much experience they may
have, should read this and other related manuals before
operating the tractor or any implement attached to it. It is
the owner's obligation to instruct all operators in safe
operation.

1. BEFORE OPERATING THE TRACTOR

1. Know your equipment and its limitations. Read this
entire manual before attempting to start and operate
the tractor.

2. Pay special attention to the danger, warning and
caution labels on the tractor.

3. Do not operate the tractor or any implement attached
to it while under the influence of alcohol, medication,
controlled substances or while fatigued.

4. Before allowing other people to use your tractor,
explain how to operate and have them read this
manual before operation.

5. Never wear loose, torn, or bulky clothing around
tractor. It may catch on moving parts or controls,
leading to the risk of an accident. Use additional safety
items, e.g. hard hat, safety boots or shoes, eye and
hearing protection, gloves, etc., as appropriate or
required.

6. Do not allow passengers to ride on any part of the
tractor at anytime. The operator must remain in the
tractor seat during operation.

7. Check brakes, clutch, linkage pins and other
mechanical parts for improper adjustment and wear.
Replace worn or damaged parts promptly. Check the
tightness of all nuts and bolts regularly. (For further
details, see "MAINTENANCE" section.)

8. Keep your tractor clean. Dirt, grease, and trash build
up may contribute to fires and lead to personal injury.

9. Use only implements meeting the specifications listed
under "IMPLEMENT LIMITATIONS" in this manual or
implements approved by KUBOTA.

10.Use proper weights on the front or rear of the tractor to
reduce the risk of upsets. When using the front loader,
put an implement or ballast on the 3-point hitch to
improve stability. Follow the safe operating
procedures specified in the implement or attachment
manual.

11. The narrower the tread, the greater the risk of a tractor
upset. For maximum stability, adjust the wheels to the
widest practical tread width for your application. (See
"TIRES, WHEELS AND BALLAST" section.)

(1) Rear wheels (A) Tread Width

12.Do not modify the tractor. Unauthorized modification
may affect the function of the tractor, which may result
in personal injury.

C CAB, ROPS

1. KUBOTA recommends the use of a CAB or 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 tractor be upset.
Check for overhead clearance which may interfere
with a CAB or ROPS.

2. Set parking brake and stop engine. Remove any
obstruction that may prevent raising or folding of the
ROPS. Do not allow any bystanders. Always perform
function from a stable position at the rear of the tractor.
Hold the top of the ROPS securely when raising or
folding. Make sure all pins are installed and locked.

3. If the CAB or ROPS is loosened or removed for any
reason, make sure that all parts are reinstalled
correctly before operating the tractor.

4. Never modify or repair any structural member of a
CAB or ROPS because welding, bending, drilling,
grinding, or cutting may weaken the structure.

5. If any structural member of the CAB or ROPS is
damaged, replace the entire structure at your local
KUBOTA Dealer.

6. If the tractor is equipped with a foldable ROPS it 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 the ROPS
should be placed in the upright and locked position
and the seat belt fastened for all other operations.)

SAFE OPERATION-2

7. Always use the seat belt if the tractor has a CAB or
ROPS.
Do not use the seat belt if a foldable ROPS is down or
there is no ROPS. Check the seat belt regularly and
replace if frayed or damaged.

(1) ROPS
(2) Seat belt

2. OPERATING THE TRACTOR

5. Check before each use that operator presence
controls are functioning correctly. Test safety systems.
(See "Checking Engine Start System" and "Checking
Operator Presence Control" in "EVERY 50 HOURS" in
"PERIODIC SERVICE" section.)
Do not operate unless they are functioning correctly.

C Working

1. Pull only from the drawbar. Never hitch to axle housing
or any other point except drawbar; such arrangements
will increase the risk of serious personal injury or death
due to a tractor upset.

Operator safety is a priority. Safe operation, specifically
with respect to overturning hazards, entails understanding
the equipment and environmental conditions at the time of
use. Some prohibited uses which can affect overturning
hazards include traveling and turning with implements
and loads carried too high etc. This manual sets forth
some of the obvious risks, but the list is not, and cannot
be, exhaustive. It is the operator's responsibility to be alert
for any equipment or environmental condition that could
compromise safe operation.

C Starting

1. Always sit in the operator's seat when starting engine
or operating levers or controls. Adjust seat per
instructions in the operating the tractor section. Never
start engine while standing on the ground.

2. Before starting the engine, make sure that all levers
(including auxiliary control levers) are in their neutral
positions, that the parking brake is engaged, and that
both the clutch and the Power Take-Off (PTO) are
disengaged or "OFF".
Fasten the seat belt if the tractor has a CAB or a
foldable ROPS in the upright and locked position.

3. Do not start engine by shorting across starter
terminals or bypassing the safety start switch.
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.

(1) Drawbar

2. For trailing PTO-driven implements, set the drawbar to
the towing position.

3. Attach pulled or towed loads to the drawbar only.

4. Keep all shields and guards in place. Replace any that
are missing or damaged.

5. Avoid sudden starts. To avoid upsets, slow down
when turning, on uneven ground, and before stopping.

6. The tractor cannot turn with the differential locked and
attempting to do so could be dangerous.

7. Do not operate near ditches, holes, embankments, or
other ground surface features which may collapse
under the tractor's weight. The risk of tractor upset is
even higher when the ground is loose or wet. Tall
grass can hide obstacles, walk the area first to be sure.

8. Watch where you are going at all times. Watch for and
avoid obstacles. Be alert at row ends, near trees, and
other obstructions.

9. When working in groups, always let the others know
what you are going to do before you do it.

10.Never try to get on or off a moving tractor.

11.Always sit in the operator's seat when operating levers
or controls.

12.Do not stand between tractor and implement or trailed
vehicle unless parking brake is applied.

-3SAFE OPERATION

C Safety for children

Tragedy can occur if the operator is not alert to the
presence of children. Children generally are attracted to
machines and the work they do.

1. Never assume that children will remain where you last
saw them.

2. Keep children out of the work area and under the
watchful eye of another responsible adult.

3. Be alert and shut your machine down if children enter
the work area.

4. Never carry children on your machine. There is no safe
place for them to ride. They may fall off and be run
over or interfere with your control of the machine.

5. Never allow children to operate the machine even
under adult supervision.

6. Never allow children to play on the machine or on the
implement.

7. Use extra caution when backing up. Look behind and
down to make sure area is clear before moving.

C Operating on slopes

Slopes are a major factor related to loss-of-control and tip­over accidents, which can result in severe injury or death.
All slopes require extra caution.

1. To avoid upsets, always back up steep slopes. If you
cannot back up the slope or if you feel uneasy on it, do
not operate on it. Stay off slopes too steep for safe
operation.

2. Driving forward out of a ditch, mired condition or up a
steep slope increases the risk of a tractor to be upset
backward. Always back out of these situations. Extra
caution is required with 4-wheel drive models because
their increased traction can give the operator false
confidence in the tractor's ability to climb slopes.

3. Keep all movement on slopes slow and gradual. Do
not make sudden changes in speed, direction or apply
brake and make sudden motions of the steering
wheel.

4. Avoid disengaging the clutch or changing gears speed
when climbing or going down a slope. If on a slope
disengaging the clutch or changing gears to neutral
could cause loss of control.

5. Special attention should be made to the weight and
location of implements and loads as such will affect the
stability of the tractor.

6. To improve stability on slope, set widest wheel tread
as shown in "TIRES, WHEELS AND BALLAST"
section.
Follow recommendations for proper ballasting.

[Manual Transmission Type]

[HST Type]

(1) Brake Pedal (LH)
(2) Brake Pedal (RH)
(3) Brake Pedal Lock

(A) Whenever travelling on the road

2. Check the front wheel engagement. The braking
characteristics are different between 2 and 4-wheel
drive. Be aware of the difference and use carefully.

3. Always slow the tractor down before turning. Turning
at high speed may tip the tractor over.

C Driving the tractor on the road

1. Lock the 2 brake pedals together to help assure
straight-line stops. Uneven braking at road speeds
could cause the tractor to tip over.

SAFE OPERATION-4

4. Make sure that the Slow Moving Vehicle (SMV) sign is
clean and visible. Use hazard lights and turn signals as
required.

(1) SMV emblem
(2) Bracket

5. Observe all local traffic and safety regulations.

6. Turn the headlights on. Dim them when meeting
another vehicle.

7. Drive at speeds that allow you to maintain control at all
times.

8. Do not apply the differential lock while traveling at road
speeds. The tractor may run out of control.

9. Avoid sudden motions of the steering wheel as they
can lead to a dangerous loss of stability. The risk is
especially great when the tractor is traveling at road
speeds.

10.Keep the ROPS in the "UP" position and wear the seat
belt when driving the tractor on the road.
Otherwise, you will not be protected in the event of a
tractor roll-over.

11.Do not operate an implement while the tractor is on the
road. Lock the 3-point hitch in the raised position.

12.When towing other equipment, use a safety chain and
place an SMV emblem on it as well.

13.Set the implement lowering speed knob in the "LOCK"
position to hold the implement in the raised position.

(1) 3-point hitch lowering speed knob (A) "FAST"

(B) "SLOW"
(C) "LOCK"

3. PARKING THE TRACTOR

1. Disengage the PTO, lower all implements to the
ground, place all control levers in their neutral
positions, set the parking brake, stop the engine,
remove the key from the ignition and lock the cab door
(if equipped). Leaving transmission in gear with the
engine stopped will not prevent tractor from rolling.
(HST type)

2. Make sure that the tractor has come to a complete
stop before dismounting.

3. Avoid parking on steep slopes, if at all possible park on
a firm and level surface; if not, park across a slope and
chock the wheels.
Failure to comply with this warning may allow the
tractor to move and could cause injury or death.

(1) Safety chain

4. OPERATING THE PTO

1. Wait until all moving components have completely
stopped before getting off the tractor, connecting,
disconnecting, adjusting, cleaning, or servicing any
PTO driven equipment.

2. Keep the PTO shaft cover in place at all times.
Replace the PTO shaft cap when the shaft is not in
use.

(1) PTO Shaft cover
(2) PTO Shaft cap

(A) "NORMAL POSITION"
(B) "RAISED POSITION"

3. Before installing or using PTO driven equipment, read
the manufacturer's manual and review the safety
labels attached to the equipment.

4. When operating stationary PTO driven equipment,
always apply the tractor parking brake and place
chocks behind and in front of the rear wheels. Stay
clear of all rotating parts. Never step over rotating
parts.

5. USING 3-POINT HITCH

1. Use the 3-point hitch only with equipment designed for
3-point hitch usage.

2. When using a 3-point hitch mounted implement, be
sure to install the proper counterbalance weight on the
front of the tractor.

3. To avoid injury from separation:
Do not extend lift rod beyond the groove on the
threaded rod.

-5SAFE OPERATION

6. SERVICING THE TRACTOR

Before servicing the tractor, park it on a firm, flat and level
surface, set the parking brake, lower all implements to the
ground, place the gear shift lever in neutral, stop the
engine and remove the key.

1. Allow the tractor time to cool off before working on or
near the engine, muffler, radiator, etc.

2. Do not remove 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
removing the cap completely. If the tractor has a
coolant recovery tank, add coolant or water to the tank,
not the radiator. (See "Checking Coolant Level" in
"DAILY CHECK" in "PERIODIC SERVICE" section.)

3. Always stop the engine before refueling. Avoid spills
and overfilling.

4. Do not smoke when working around battery or when
refueling. Keep all sparks and flames away from
battery and fuel tank. The battery presents an
explosive hazard, because it gives off hydrogen and
oxygen especially when recharging.

5. Before "jump starting" a dead battery, read and follow
all of the instructions. (See "JUMP STARTING" in
"OPERATING THE ENGINE" section.)

6. Keep first aid kit and fire extinguisher handy at all
times.

7. Disconnect the battery's ground cable before working
on or near electric components.

8. To avoid the possibility of battery explosion, do not use
or charge the refillable type battery if the fluid level is
below the LOWER ( lower limit level ) mark. Check the
fluid level regularly and add distilled water as required
so that the fluid level is between the UPPER and
LOWER levels.

9. To avoid sparks from an accidental short circuit,
always disconnect the battery's ground cable (-) first
and reconnect it last.

(1) Groove

(1) Battery

10.Do not attempt to mount a tire on a rim. This should be
done by a qualified person with the proper equipment.

SAFE OPERATION-6

11.Always maintain the correct tire pressure. Do not
inflate tires above the recommended pressure shown
in the operator's manual.

12.Securely support the tractor when either changing
wheels or adjusting the wheel tread width.

13.Make sure that wheel bolts have been tightened to the
specified torque.

14.Do not work under any hydraulically supported
devices. They can settle, suddenly leak down, or be
accidentally lowered. If it is necessary to work under
tractor or any machine elements for servicing or
adjustment, securely support them with stands or
suitable blocking beforehand.

15.Escaping hydraulic fluid under pressure has sufficient
force to penetrate skin, causing serious personal
injury. Before disconnecting hydraulic lines, be sure to
release all residual pressure. Before applying
pressure to the hydraulic system, make sure that all
connections are tight and that all lines, pipes, and
hoses are free of damage.

16.Fluid escaping from pinholes may be invisible. Do not
use hands to search for suspected leaks; use a piece
of cardboard or wood. Use of safety goggles or other
eye protection is also highly recommended. If injured
by escaping fluid, see a medical doctor at once. This
fluid will produce gangrene or severe allergic reaction.

(1) Cardboard
(2) Hydraulic line
(3) Magnifying glass

17.Do not open high-pressure fuel system.
High-pressure fluid remaining in fuel lines can cause
serious injury. Do not disconnect nor attempt to 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.

18.To avoid hazardous high voltage, turn the key switch
to the OFF position if it is necessary to check to repair
the computer, harness or connectors.

19.During Diesel Particulate Filter (hereinafter called
DPF) regenerating operations, exhaust gases and
exhaust filter components reach temperatures hot
enough to burn people, or ignite or melt common
materials.

20.Keep the tractor away from people, animals or
structures which may be susceptible to harm or
damage from hot exhaust gases.

21.To prevent fires, keep the DPF muffler and its
surroundings clear of anything flammable and keep
clean at all times.

22.During regeneration, white exhaust gas may be
visible. Do not allow regeneration in a non-ventilated
space.

23.During regeneration, do not leave the tractor.

7. DANGER, WARNING AND CAUTION LABELS

-7SAFE OPERATION

SAFE OPERATION-8

-9SAFE OPERATION

8. CARE OF DANGER, WARNING AND CAUTION LABELS

1. Keep danger, warning and caution labels clean and free from obstructing material.

2. Clean danger, warning and caution labels with soap and water, dry with a soft cloth.

3. Replace damaged or missing danger, warning and caution labels with new labels from your local KUBOTA Dealer.

OPERATING THE ENGINE

EXHAUST AFTERTREATMENT DEVICES

To avoid personal injury or death:
A Read "Safe Operation" in the front of this

manual.

A Read the danger, warning and caution labels

located on the tractor.

A To avoid the danger of exhaust fume

poisoning, do not operate the engine in a
closed building without proper ventilation.

A Never start engine while standing on ground.

Start engine only from operator's seat.

A Make it a rule to set all shift levers to the

"NEUTRAL" positions and to place PTO clutch
control switch in "OFF" position before starting
the engine.

To avoid personal injury or death:
A During Diesel Particulate Filter (DPF)

regenerating operations, exhaust gases and
exhaust filter components reach temperatures
hot enough to burn people, or ignite or melt
common materials.

A Keep tractor away from people, animals or

structures which may be susceptible to harm
or damage from hot exhaust gases.

A During regeneration, white exhaust gases may

be visible. Do not allow regeneration in a non
ventilated garage or confined area.

A During regeneration, do not leave the tractor.

13OPERATING THE ENGINE

A Do not use starting fluid or ether.
A To protect the battery and the starter, make sure that

the starter is not continuously turned for more than 10
seconds.

BDiesel Particulate Filter (DPF) Muffler

This tractor is equipped with an engine with a DPF (Diesel
Particulate Filter) muffler which serves to reduce
hydrocarbons, carbon monoxide and other gases, all of
which are contained in diesel engine emissions, to
harmless carbon dioxide and water. The DPF also traps
PM (particulate matter).
Please handle exhaust aftertreatment devices correctly
and in an environmentally responsible manner.

(1) Diesel Particulate Filter (DPF)

OPERATING THE ENGINE14

BHandling Points

When a specific amount of PM (particulate matter) has
accumulated in the DPF muffler, it is necessary to refresh
the DPF muffler by burning the PM inside it. This burning
off work is called "Regeneration".
To extend operating time to reach this regeneration, and
to avoid DPF muffler trouble, make sure to observe the
following handling matters.

C Fuel

Be sure to use Ultra Low Sulfur Fuel (S15).

A Use of diesel fuel other than Ultra Low Sulfur Fuel

may adversely affect the engine and DPF
performance.
Use of fuels other than Ultra Low Sulfur Fuel (S15)
may not meet regulations for your region.

C Engine oil

Use DPF-compatible oil (CJ-4) for the engine.

A If any engine oil other than CJ-4 is used, the DPF

may become clogged earlier than expected and the
fuel economy may drop.

C Prohibition of unnecessary idling operation

Generally, the lower the engine speed, the lower the
exhaust gas temperature is, so the PM contained in
exhaust gas will not be burnt, and begins to accumulate.
Therefore, don't idle unnecessarily.

C Regeneration

When there is "Regeneration" instruction sign by lamp or
buzzer, immediately perform the required procedure for
regeneration.

A Interrupting the regeneration cycle or continued

operation by ignoring the warning signs may cause
DPF and engine damage.

BDPF Regeneration Process

DPF regeneration process can be performed by choosing
from "Auto Regeneration" or "Regeneration inhibit" mode
according to your job conditions. For jobs not affected by
hot gases emitted during regeneration, the "Auto
Regeneration" is advisable.

C Auto Regeneration Mode;

When starting the engine (switch operation is
unnecessary), the "Auto Regeneration" mode is
automatically activated.
With the auto regeneration mode on, when a specific
amount of PM has accumulated, and the regeneration
conditions are satisfied (See the "Tips on Diesel
Particulate Filter [DPF] Regeneration"), the DPF will be
automatically regenerated whether the tractor is in
motion or parked.
By this way, work efficiency is improved. For details of
auto regeneration, refer to "Operating Procedure for
Auto Regeneration Mode" section.

C Regeneration Inhibit Mode;

After starting the engine, if the "DPF INHIBIT switch" is
pressed to turn on the switch lamp, the "Regeneration
inhibit" mode will be activated.
With "Regeneration Inhibit" mode on, the PM which has
accumulated inside the DPF will not be burnt, unless the
operator performs the regeneration work manually.
The "Regeneration Inhibit" mode is effective for work in
poorly ventilated work spaces.
For details of regeneration prohibition, refer to
"Operating Procedure for Regeneration Inhibit Mode"
section.

A If stop the engine once, the "Auto Regeneration" mode

will be activated.

OPERATING THE ENGINE20

BTips on Diesel Particulate Filter (DPF)

Regeneration

A Operation

The higher in speed or load the engine operates, the
higher the exhaust temperature rises. As a result,
particulate matter (PM) inside the DPF is consumed,
therefore the regeneration process is required less
frequently over time.
The lower in speed or load the engine operates, the
lower the exhaust temperature. Accordingly, less
particulate matter (PM) inside the DPF is consumed,
therefore more accumulation of PM will occur, which
requires frequent regeneration, therefore avoid
prolonged idling if possible.

A Necessary conditions for "Regeneration"

When conditions below are all satisfied, regeneration
will start. However, if even one condition is deviated
during the process, the regeneration will be
interrupted.
(1) The engine coolant temperature.
(2) The DPF temperature.
(3) The engine speed is 1200 rpm or higher.

A Usually it takes 15-20 minutes to complete the

regeneration cycle.
Actual regeneration time may depend on ambient
temperature, exhaust temperature and engine speed.

STARTING THE ENGINE

1. Make sure the parking brake is set.

1. To set the parking brake;
(1) Interlock the brake pedals.
(2) Depress the brake pedals.
(3) Latch the brake pedals with the parking brake

lever.

2. To release the parking brake, depress the brake
pedals again.

[Manual Transmission Type]

A It is recommended to do the regenerating while the

engine is warm.

A Do not unnecessarily start and interrupt the

regeneration process. Otherwise, a small amount of
fuel becomes mixed with the engine oil, which
degrades the oil quality.

A While the DPF is being regenerated, the engine air

flow rate is automatically limited to keep up the
exhaust temperature. Because of this the engine may
sound differently, this is normal for this engine.

A Just after the regeneration has ended, the DPF muffler

remains hot. It is advisable to keep the engine running
for about 5 minutes to allow cooling of the exhaust
components.

5 minutes for turbo to slow down then
turn the key to "OFF".

2. Remove the key.

A If key does not stop the engine, consult your local

KUBOTA Dealer.

WARMING UP

To avoid personal injury or death:
A Be sure to set the parking brake during warm-

up.

A Be sure to set all shift levers to the "NEUTRAL"

positions and to place PTO clutch control
switch in "OFF" position during warm-up.

For 5 minutes after engine start-up, allow engine to warm
up without applying any load, this is to allow oil to reach
every engine part. If load should be applied to the engine
without this warm-up period, trouble such as seizure,
breakage or premature wear may develop.

BWarm-Up Transmission Oil in the Low

Temperature Range

Hydraulic oil serves as transmission fluid. In cold weather,
the oil may be cold with increased viscosity. This can
cause delayed oil circulation or abnormally low hydraulic
pressure for some time after engine start-up. This in turn
can result in trouble in the hydraulic system. To prevent
the above, observe the following instructions:
Warm up the engine at about 50% of rated rpm according
to the table below:

Ambient temperature Warm-up time requirement

Higher than -10 (14 ) Approx. 5 minutes

-15 to -10 (5 to 14 ) 5 to 10 minutes

-20 to -15 (-4 to 5 ) 10 to 20 minutes

Below -20 (-4 ) More than 20 minutes

A Do not operate the tractor under full load condition until

it is sufficiently warmed up.

OPERATING THE ENGINE26

JUMP STARTING

To avoid personal injury or death:
A Battery gases can explode. Keep cigarettes,

sparks, and flames away from battery.

A If tractor battery is frozen, do not jump start

engine.

A Do not connect the other end of the negative

(-) jumper cable to the negative (-) terminal of
the tractor battery.

When jump starting the engine, follow the instructions
below to safely start the engine.

1. Bring the helper vehicle with a battery of the same
voltage as disabled tractor within easy cable reach.
"THE VEHICLES MUST NOT TOUCH".

2. Engage the parking brakes of both vehicles and put
the shift levers in neutral. Shut both engines off.

3. Wear eye protection and rubber gloves.

4. Attach the red clamp to the positive (red, (+) or pos.)
terminal of the dead battery and clamp the other end
of the same cable to the positive (red, (+) or pos.)
terminal of the helper battery.

5. Clamp the other cable to the negative (black, (-) or
neg.) terminal of the helper battery.

6. Clamp the other end to the engine block or frame of
the disabled tractor as far from the dead battery as
possible.

7. Start the helper vehicle and let its engine run for a few
moments. Start the disabled tractor.

8. Disconnect the jumper cables in the exact reverse
order of attachment. (Steps 6, 5 and 4).

A This machine has a 12 volt negative (-) ground starting

system.

A Use only same voltage for jump starting.
A Use of a higher voltage source on tractor's electrical

system could result in severe damage to tractor's
electrical system.
Use only matching voltage source when "Jump
starting" a low or dead battery condition.

A Do not operate the tractor with the battery cable

disconnected from the battery.

A Do not operate the tractor without the battery

mounted.

A Do not operate the tractor with the battery dead.

OPERATING THE TRACTOR

27OPERATING THE TRACTOR

OPERATING NEW TRACTOR

How a new tractor is handled and maintained determines
the life of the tractor.
A new tractor just off the factory production line has been,
of course, tested, but the various parts are not
accustomed to each other, so care should be taken to
operate the tractor for the first 50 hours at a slower speed
and avoid excessive work or operation until the various
parts become "broken-in". The manner in which the
tractor is handled during the "breaking-in" period greatly
affects the life of your tractor. Therefore, to obtain the
maximum performance and the longest life of the tractor,
it is very important to properly break-in your tractor. In
handling a new tractor, the following precautions should
be observed.

BDo not Operate the Tractor at Full Speed

for the First 50 Hours

A Do not start quickly nor apply the brakes suddenly.
A In winter, operate the tractor after fully warming up the

engine.

A Do not run the engine at speeds faster than

necessary.

A On rough roads, slow down to suitable speeds.

Do not operate the tractor at fast speed.

The above precautions are not limited only to new
tractors, but to all tractors. But it should be especially
observed in the case of new tractors.

BChanging Lubricating Oil for New Tractors

The lubricating oil is especially important in the case of a
new tractor. The various parts are not "broken-in" and are
not accustomed to each other; small metal grit may
develop during the operation of the tractor; and this may
wear out or damage the parts. Therefore, care should be
taken to change the lubricating oil a little earlier than
would ordinarily be required.
For further details of change interval hours.
(See "MAINTENANCE" section.)

BOARDING AND LEAVING THE TRACTOR

1. Never try to get on or off a moving tractor or jump off
the tractor to exit.

2. Face the tractor when getting into or out of the tractor.
Do not use the controls as hand holds to prevent
inadvertent machine movements.

3. Always keep steps and floor clean to avoid slippery
conditions.

BBrake Pedals (Right and Left)

To avoid personal injury or death:
A Be sure to interlock the right and left pedals.

Applying only one rear wheel brake at high
speeds could cause the tractor to swerve or
roll-over.

A Be sure brake pedals have equal adjustment

when using locked together. Incorrect or
unequal brake pedal adjustment can cause the
tractor to swerve or roll-over.

To avoid personal injury or death:
A Do not make brake suddenly.

An accident may occur as a result of a heavy
towed load shifting forward or loss of control.

A To avoid skidding and loss of steering control

when driving on icy, wet, or loose surfaces,
make sure the tractor is correctly ballasted,
operated at reduced speed, operated with front
wheel drive engaged (if equipped).

A The braking characteristics are different

between 2 and 4-wheel drive. Be aware of the
difference and use carefully.

1. Before operating the tractor on the road or before
applying the parking brake, be sure to interlock the
right and left pedals as illustrated below.

2. Use individual brakes to assist in making sharp turns

To avoid personal injury or death:
A Always back up when going up a steep slope.

Driving forward could cause the tractor to tip
over backward. Stay off hills and slopes too
steep for safe operation.

A Avoid changing gears when climbing or

descending a slope.

A If operating on a slope, never disengage the

clutch or shift levers to neutral. Doing so could
cause loss of control.

A Do not drive the tractor close to the edges of

ditches or banks which may collapse under the
weight of the tractor. Especially when the
ground is loose or wet.

A Tow the tractor using its front hitch or drawbar.
A Never tow faster than "10 km/h (6.2 mph)".

BDirections for Use of Power Steering

1. Power steering is activated only while the engine is
running. Slow engine speeds make the steering a little
heavier. While the engine is stopped, the tractor
functions in the same manner as tractors without
power steering.

2. When the steering wheel is turned all the way to the
stop, the relief valve is activated. Do not hold the
steering wheel in this position for a long period of time.

3. Avoid turning the steering wheel while the tractor is
stopped, or tires may wear out sooner.

4. The power steering mechanism makes the steering
easier. Be careful when driving on a road at high
speeds.

HYDRAULIC UNIT

A Do not operate until the engine is warmed up. If

operation is attempted when the engine is still cold, the
hydraulic system may be damaged.

A If noises are heard when implement is lifting after the

hydraulic control lever has been activated, the
hydraulic mechanism is not adjusted properly. Unless
corrected, the unit will be damaged. Contact your
KUBOTA Dealer for adjustment.

3-POINT HITCH CONTROL SYSTEM

To avoid personal injury or death:
A Before using the 3-point hitch controls, ensure

that no person or object is in the area of the
implement or 3-point hitch. Do not stand on or
near the implement or between the implement
and tractor when operating the 3-point hitch
controls.

BPosition Control

This will control the working depth of 3-point implements
regardless of the amount of pull required.
Place the draft control lever in the lowest position and set
the implement working depth with the position control
lever.

BDraft Control (if equipped)

This will control the pull of the 3-point implement. As the
load on the 3-point hitch changes due to various soil
conditions, the draft control system automatically
responds to these changes by either raising or lowering
the implement slightly to maintain a constant pull.
Place the position control lever in the lowest position and
set the implement pull with the draft control lever.

BMixed Control

In draft control, when draft decreases, the implement
automatically lowers to increase draft. However, the
implement sometimes lowers too much. To limit the
degree, the implement can be lowered, set the position
control lever at the lowest working depth desired for the
implement. Lower the draft control lever to the point where
the implement is at the desired depth.
This stops the implement from going too deep and
causing loss of traction and ground speed.

53HYDRAULIC UNIT

B3-point Hitch Lowering Speed

To avoid personal injury or death:
A Fast lowering speed may cause damage or

injury. Lowering speed of implement should be
adjusted to 2 or more seconds.

The lowering speed of the 3-point hitch can be controlled
by adjusting the 3-point hitch lowering speed knob.

(1) Ground surface
(2) Implement penetrate limit
(3) Light soil

BFloat Control

[with Draft control]

Place both the draft control lever and the position control
lever in the float position to make the lower links move
freely along with the ground conditions.

AUXILIARY HYDRAULICS

BHydraulic Block Type Outlet

Hydraulic block type outlet is useful when adding
hydraulically operated implement such as: front end
loader, front blade, etc.

When implement is attached

1. Remove the block cover.

2. Route the implement inlet, outlet, and return hoses as
shown in the illustration.

REMOTE HYDRAULIC CONTROL SYSTEM (if equipped)

The hydraulic auxiliary control valves can be installed up
to triple segments.

BRemote Control Valve

There are two types of remote valves available for these
models.

A Double acting valve:
A Double acting valve with float position:

This valve may be placed in the float mode with the
control lever all the way forward. The cylinder is free to
extend or retract, letting an implement such as a
loader bucket follow the ground.

A The floating valve can be attached as the second

segment only.

BRemote Control Valve Lever

The remote control valve lever directs pressurized oil flow
to the implement hydraulic system.

To avoid personal injury or death:
A Do not attempt to mount a tire on a rim. This

should be done by a qualified person with the
proper equipment.

A Always maintain the correct tire pressure.

Do not inflate tires above the recommended
pressure shown in the operator's manual.

A Do not use tires other than those approved by

KUBOTA.

BInflation Pressure

Though the tire pressure is factory-set to the prescribed
level, it naturally drops slowly in the course of time. Thus,
check it everyday and inflate as necessary.

A Maintain the maximum pressure in front tires, if using

a front loader or when equipped with a full load of front
weights.

BALLAST

To avoid personal injury or death:
A Additional ballast will be needed for

transporting heavy implements. When the
implement is raised, drive slowly over rough
ground, regardless of how much ballast is
used.

A Do not fill the front wheels with liquid to

maintain steering control.

BFront Ballast

Add weights if needed for stability (2WD, 4WD models)
and improve traction (4WD model). Heavy pulling and
heavy rear mounted implements tend to lift front wheels.
Add enough ballast to maintain steering control and
prevent tip over. Remove weight when no longer needed.

C Front End Weights (option)

The front end weights can be attached to the bumper. See
your implement operator's manual for required number of
weights or consult your local KUBOTA Dealer to use.

TIRES, WHEELS AND BALLAST62

BRear Ballast

Add weight to rear wheels if needed to improve traction or
for stability. The amount of rear ballast should be matched
to job and the ballast should be removed when it is not
needed.
The weight should be added to the tractor in the form of
liquid ballast, rear wheel weights or a combination of both.

C Rear Wheel Weights (option)

The rear wheel weights can be attached to the rear wheel.
See your implement operator's manual for required
number of weights or consult your local KUBOTA Dealer
to use.

BLiquid Ballast in Rear Tires

Water and calcium chloride solution provides safe
economical ballast. Used properly, it will not damage tires,
tubes or rims. The addition of calcium chloride is
recommended to prevent the water from freezing. Use of
this method of weighting the wheels has the full approval
of the tire companies. See your tire dealer for this service.

BChecking Battery Condition

To avoid the possibility of battery explosion:
For the refillable type battery, follow the
instructions below.
A 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.

To avoid personal injury or death:
A Never remove the battery cap while the engine

is running.

A Keep electrolyte away from eyes, hands and

clothes. If you are spattered with it, wash it
away completely with water immediately and
get medical attention.

A Keep open sparks and flames away from the

battery at all times. Hydrogen gas mixed with
oxygen becomes very explosive.

A Wear eye protection and rubber gloves when

working around battery.

The factory-installed battery is of non-refillable
type. If the indicator turns white, do not charge the
battery but replace it with new one.
