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 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. If the CAB or ROPS is loosened or removed for any
reason, make sure that all parts are reinstalled
correctly before operating the tractor.
3. Never modify or repair any structural member of a
CAB or ROPS because welding, bending, drilling,
grinding, or cutting may weaken the structure.
4. A damaged CAB or ROPS structure must be replaced,
not repaired or revised.
5. If any structural member of the CAB or ROPS is
damaged, replace the entire structure at your local
KUBOTA Dealer.
6. Always use the seat belt if the tractor has a CAB or
ROPS. Do not use the seat belt if there is no CAB or
ROPS. Check the seat belt regularly and replace if
frayed or damaged.
Page 12
SAFE OPERATION-2
(1) CAB
(2) Seat belt
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.
2. OPERATING THE TRACTOR
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, a fixed
ROPS 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.
5. Check before each use that operator presence
controls are functioning correctly. Test safety systems.
(See "Checking Engine Start System" in "EVERY 50
HOURS" in "PERIODIC SERVICE" section.)
Do not operate unless they are functioning correctly.
(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 rear wheel or 4-wheel
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 use "Bi-speed Turn" at high speed.
13."Bi-Speed Turn" enables short and fast turns,
therefore, become familiar with its performance before
operating in close or confined areas.
14.Do not stand between tractor and implement or trailed
vehicle unless parking brake is applied.
C Instructional seat (if equipped)
1. Instructional seat is provided only for training and
instructing operators or diagnosing machine problems.
2. It is not intended to carry children nor any other person
for any other purpose.
3. Always wear your seat belt and stabilize your body by
holding the handrail on the CAB frame.
Page 13
-3SAFE OPERATION
4. Use caution to avoid the risks of obstructing operator's
view, falling from the machine and interfering with
controls.
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 four-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.
7. To avoid free wheeling:
A Do not shift the shuttle lever while on a slope.
A Stop completely by using the brake and by
depressing the clutch pedal, then shift the shuttle
lever.
A Start off after selecting shuttle direction, by
releasing the clutch pedal.
C Driving the tractor on the road
1. Lock the two brake pedals together to help assure
straight-line stops. Uneven braking at road speeds
could cause the tractor to tip over.
(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 two and four
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.
4. Observe all local traffic and safety regulations.
Use the registration plate as required.
(1) Registration plate
5. Turn the headlights on. Dim them when meeting
another vehicle.
6. Drive at speeds that allow you to maintain control at all
times.
7. Do not apply the differential lock while traveling at road
speeds. The tractor may run out of control.
Page 14
SAFE OPERATION-4
8. 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.
9. Do not operate an implement while the tractor is on the
road. Lock the 3-point hitch in the raised position.
10.Set the implement lowering control in the "LOCK"
position to hold the implement in the raised position.
(1) 3-point hitch lowering lock lever (A) "LOCK"
(B) "UNLOCK"
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.
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 with
chock the wheels.
Failure to comply with this warning may allow the
tractor to move and could cause injury or death.
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.
To prevent PTO driven equipment from improper or
unsafe use, select the lower speed (540rpm) unless
the higher one is specifically recommended as safe by
the equipment manufacture.
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.
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.
Page 15
-5SAFE OPERATION
3. To avoid injury from separation:
Do not extend lift rod beyond the groove on the
threaded rod.
(1) Groove
4. Use [UP-DOWN] switch or lever only on farm fields.
For all other application, use hydraulic lever to move
attachment.
6. SERVICING THE TRACTOR
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) Battery
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.
(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.
Page 16
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.Disconnect the battery's ground cable and stop the
engine to avoid the possibility of the machine runaway
due to 4WD braking system during testing, service or
repair with only rear wheels off the ground.
15.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.
16.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.
17.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
18.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.
19.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.
20.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.
21.Keep tractor away from people, animals or structures
which may be susceptible to harm or damage from hot
exhaust gases.
22.To prevent fires, keep the DPF muffler and its
surroundings clear of anything flammable and keep
clean at all times.
23.During regeneration, white exhaust gas may be
visible. Do not allow regeneration in a non-ventilated
space.
24.During regeneration, do not leave the tractor.
25.Before servicing a tractor equipped with the front
suspension, be sure to lower the machine to the lowest
position.
26.The front suspension hydraulic circuit is still under high
pressure after the engine has stopped. Do not
disconnect the pipes and/or hoses because you may
get injured by high-pressure oil. If pipes and/or hoses
are found worn or damaged, consult your local
KUBOTA Dealer for this service.

OPERATING THE ENGINE
BDiesel Oxidation Catalyst and Diesel
To avoid personal injury:
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.
A When the engine is started, the machine height
may change unexpectedly. Before starting the
tractor, make sure the area near the machine is
clear of all persons and objects. [Front
suspension type].
Particulate Filter (DPF) Muffler
The Diesel Oxidation Catalyst and Diesel Particular Filter
(Hereinafter called DPF) serves to reduce hydrocarbons,
carbon monoxide and other toxic gases, all of which are
contained in diesel engine emissions, to harmless carbon
dioxide and water. The DPF also traps Particulate Matter
(PM).
To meet the emission regulations in your country, the DPF
is installed on your tractor.
Be sure to read this operator's manual before running in
your tractor.
It is imperative for the tractor owner and operator to
handle the DPF in a safe and environmentally responsible
manner.
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.
EXHAUST AFTERTREATMENT DEVICES
To avoid personal injury:
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.
(1) Diesel Particulate Filter (DPF)
A When the DPF has trapped a specific amount of
particulate matter (PM), the engine computer starts
the process of regeneration or burning of soot
collected by the filter.
This burning process is called regeneration.
Page 37
BHandling Points
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.
BDPF Regeneration Process
This system has "Parked Regeneration" in which the DPF
regenerates while the tractor is parked and "Automatic
Regeneration" which the DPF can regenerate
automatically while working.
When key switch is turned ON, the tractor will be in the
"Inhibit Mode". By pressing the auto regeneration switch,
the mode can be switched to the "Auto Regeneration
Mode".
Choose from them according to your job condition, usage
environment and other factors.
15OPERATING THE ENGINE
C Inhibit Mode;
The tractor has been set to Inhibit Mode by default.
Even if an amount of PM more than specified has built
up in the DPF muffler, the DPF does not regenerate.
When the regeneration is needed, the indicator starts
flashing to notify the operator to active either Auto
Regeneration Mode or conduct a Parked Regeneration
Mode, once in a safe area.
For jobs that are done in poorly ventilated area or in area
that may affect plants and animals because of hot gases
that will be emitted, the Inhibit Mode is recommended.
C Parked Regeneration Mode;
When an amount of PM more than specified has built up
in the DPF, the indicator starts flashing to notify the
operator that Regeneration is required. Therefore, park
the tractor in a safe place and carry out the regeneration.
C Auto Regeneration Mode;
Press the auto regeneration switch, and the Auto Mode
is activated.
When an amount of PM more than specified has built up
in the DPF muffler, the DPF is automatically regenerated
whether the tractor is in motion or parked.
For jobs not affected by hot gases emitted out of the DPF
muffler during regeneration, the Auto Mode is advisable.
Page 38
16 OPERATING THE ENGINE
Operating Procedure for Parked Regeneration
1. Park the tractor in a safe area away from buildings, people, and animals.
2. Apply the parking brake.
3. Set the power shift / range shift lever and the shuttle shift lever to the neutral position.
4. Turn "OFF" the PTO clutch control switch.
5. Return the engine rpm to the idle speed.
6. Once the parked regeneration switch starts flashing.
7. Press the parked regeneration switch to start the regeneration cycle.
(The switch light will remain "ON" constantly during the cycle.)
8. The engine rpm will automatically rise, and the regeneration process will begin.
9. Make sure the indicators stay "ON" while regenerating the DPF. They turn "OFF" when the cycle
is complete. The tractor can be moved and continue working.
During the regeneration cycle, do not touch the above levers, and switches, nor change the engine rpm. Otherwise, the
regeneration will be interrupted. Never leave the tractor when parked regeneration process is activated. Once
Regeneration process is complete, the tractor may be moved and returned to work.
A If the parked regeneration cycle is interrupted, the engine rpm is fixed at the idling level for about 30 seconds. For this
period, keep the hand throttle lever and foot throttle pedal at the idle position. Do not move them. They will function
again in 30 seconds.

21OPERATING THE ENGINE
BTips on 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 occurs 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 Auto Regeneration Mode specified conditions
In order for the Auto Regeneration to begin, all of the
listed conditions must be satisfied. If any one of the
listed conditions are not satisfied, the process can not
begin.
(1) The engine coolant temperature.
(2) The DPF temperature.
(3) The engine speed is around 1200 rpm or higher.
A Usually it takes 15-20 minutes to complete the
regeneration cycle.
It may depend on ambient temperature, exhaust
temperature and engine speed.
STARTING THE ENGINE
1. Make sure the parking brake is set.
Pull the parking brake lever up to park.
The parking brake indicator light on the Easy
Checker(TM) will come on while the parking brake is set.
(1) Parking brake lever
(2) Release button
(A) "PULL"
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.

WARMING UP
To avoid personal injury:
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 switch in "OFF"
position during warm-up.
For five 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.
10. Turn the key to the start position and
the engine should start.
(If the engine fails to start after 10 seconds, turn off the
key for 30 seconds. Then repeat steps 9 and 10. To
protect the battery and the starter, make sure that the
starter is not continuously turned for more than 10
seconds.)
BBlock Heater (if equipped)
A block heater is available as an option from your dealer.
It will assist you in starting your tractor when the ambient
temperature is below -20 .
BWarm-up and Transmission Oil at 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 0 Approx. 5 minutes
0 to -10 10 to 20 minutes
-10 to -20 20 to 30 minutes
Below -20 More than 30 minutes
A Do not operate the tractor under full load condition until
it is sufficiently warmed up.

28 OPERATING THE TRACTOR
OPERATING 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.
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.
STARTING
1. Adjusting the Operator's Position.
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.)
A The seat and suspension should be adjusted to
ensure that the controls are comfortably at hand for the
operator, ensuring that the operator maintains a good
posture and minimizes risks from whole body
vibration.
BOperator's Seat
To avoid personal injury:
A Make adjustments to the seat only while the
tractor is stopped.
A Make sure that the seat is completely secured
after each adjustment.
A Do not allow any person other than the
operator to ride on the tractor.

A To prolong clutch life, avoid slipping the hydraulic
clutch. Pay attention to the following points:
A Select proper gear and engine speed depending
on the type of job.
A Avoid lugging the engine, especially in higher
gears. If RPM's drop excessively, shift to a lower
gear.
A In cold climate, it may take longer for the tractor to
move after the PS.lever is moved. This is because the
transmission oil must warm up.
A Properly warm up the machine. If there is not
enough time to do so, start the machine with the
clutch pedal slowly.
A There is no problem with a delay in starting.
The machine will start as the oil temperature
increases.

37OPERATING THE TRACTOR
A While the DHC switch is at "ON", the hydraulic clutch
behaves quicker at a speed change. Even working on
a slope, therefore, the push-out of an attachment can
be minimized. (Do not change speeds when doing
heavy-duty traction on a steep slope.)
BShuttle Lever
To avoid personal injury:
A When attempting to shift the shuttle shift lever
on a slope, be sure to completely stop the
tractor.
A Slow down the engine speed before shifting the
shuttle lever.
A Use the shuttle lever when the machine speed
is below 11 km/h.
A Otherwise the clutch gets disengaged and the buzzer
starts sounding.
To get the clutch reengaged and clear the buzzer, take
either of the following steps.
(1) Place the shuttle lever back to the original
position. Decrease the machine speed lower than
11 km/h and use the shuttle lever.
(2) Stop the tractor first and bring the shuttle lever
back to the original position.
A While the shuttle shift lever is at the “NEUTRAL”
position, the “N” character appears on the LCD
monitor.
(N) "NEUTRAL"
BCreep Lever (if equipped)
Shift the creep lever at " " to obtain low speeds with
power shift / range shift lever is selected "L" range.
With the creep lever engaged (ON), the speed range
cannot shift to "M" and "H". (The creep mode does not
operate in the middle-speed and high-speed ranges.)
This shifting requires clutch operation.
Raise up and shift the shuttle shift lever forward to obtain
forward speeds and shift it backward to obtain reverse
speeds without using the clutch pedal.
With the shuttle lever at neutral, press the up-shift/downshift button of the power shift / range shift lever, select the
main speed (1st thru 8th speed) and then switch the subspeed range. Now the selected main speed is kept on
whether at "L", "M" or "H".

ELECTRONIC ENGINE CONTROL
The electronically controlled engine which is installed in
this tractor performs the following three types of control.
1. Rev-limiter control setting
2. RPM dual memory setting
3. Constant RPM management control
BRev-limiter Control Setting
When the Rev-limiter control dial is used to restrict the
maximum engine speed, the engine speed will not exceed
the set speed even when the hand throttle lever or foot
throttle is operated. This can prevent machine trouble
caused by incorrect operation.
C Setting the speed
1. The setting can be made both when the engine is
running and when it is stopped.
2. Set the speed by turning the dial to the left or right
while watching the engine speed that is displayed on

BConstant RPM Management Control
Constant RPM Management can be turned "ON" or "OFF"
by operating the switch. Pressing the switch to the lower
side turns the control "ON" and pressing the switch to the
upper side turns it "OFF".
C When constant RPM management is "ON"
Fluctuations in the engine speed due to load fluctuations
are reduced and the travel speed and PTO speed are kept
nearly constant, allowing stable work. When constant
RPM management is "ON", the switch and the instrument
panel indicator light up.
C When constant RPM management is "OFF
As in a conventional engine, the engine speed increases
or decreases according to changes in the load. The
operator judges the size of the load from the engine speed
and engine sound, and can adjust the travel speed or
plowing depth to prevent overload on the tractor.
A In a mechanically-controlled engine, the engine speed
changes according to increases and decreases in the
load.
For example, when working in a hilly area, the load
increases and engine speed drops while ascending a
slope, and conversely the load drops when
descending. These changes in engine speed affect
the travel speed and PTO-driven implements. In order
to minimize these effects, the operator must make fine
adjustments to the travel speed and hand throttle
lever.
When the constant RPM management switch in this
tractor with its electronically controlled engine is
turned "ON", the engine speed will be kept nearly
constant in response to a certain level of load
fluctuations. This improves the accuracy of work
without the need for troublesome manipulation of the
travel speed and hand throttle lever.
A It is recommended that a combination of light-load
PTO-driven implements and AUTO-MODE (Automatic
speed change) be used.
A There is a limit to the range within which a constant
speed can be maintained. If a load exceeding the
engine performance is applied, the engine speed will
drop.
A The purpose of constant RPM management is not to
increase the engine power.

AUTO MODE
BOutline
The Auto-Mode is an automatic speed change function that is designed to shift up and down the travel speed in response
to the load-dependent engine rpm fluctuations, attachment maneuvering, acceleration pedal movement and other factors.
The Auto-Mode comes in two ways, "Travel mode" and "Field mode", according to the applications.
C Travel mode
In trailing operation, the automatic shift-up/down is carried out within a predetermined range (factory-set for 2 shifts),
responding to the acceleration pedal movement and rpm changes from load. This helps you avoid troublesome gear
shifting.
A The tractor has been factory-set for the automatic range (2 shifts) discussed above. This gearshift range can be
modified to meet your applications. (For details, refer to "Changing the Auto-Mode settings" in this section.)
A The Auto-Mode does not function if the clutch is disengaged or halfway or in turning over the Bi-speed turning angle
and if shuttle lever is in reverse position.
A The Auto-Mode functions when the engine rpm is above the middle speed.
Page 74
52 OPERATING THE TRACTOR
C Field mode
In plowing operation, the automatic shift-up/down is carried out within a predetermined range (factory-set for 2 shifts),
responding to the field condition, soil condition and other factors. When lifting the attachment using 3 pt, the automatic shiftdown is made for easier turning.
With implement that require PTO rotation, automatic shift-up/shift-down occurs repeatedly. This is because the system is
sensitive to the load from the plow or other towed implements. As a result, the PTO speed is kept nearly constant, improving
the accuracy of work.

59OPERATING THE TRACTOR
FRONT SUSPENSION
To avoid personal injury:
A The front suspension control system is
working when the engine is running. In the ON
mode, the LOCK mode or the AUTO LOCK
mode, the control system will subtly change
the machine's height at startup or as weight
changes when implements are attached. These
subtle movements can be unexpected. Before
starting it, make sure the area near the machine
is clear of all persons and objects.
BOutline
The front suspension system works to absorb shocks and
vibrations that can be caused by field surface conditions,
road surface conditions, and changes in weight caused by
implements. Different implements can change the way a
tractor carries weight and that weight is also changed
when driving in the field or driving on the road. The front
suspension system provides the operator with a smoother
ride, improved tractor stability, and higher productivity.
The front suspension control system has two control
switches that allow the operator to adjust the suspension
system to operating conditions. Those switches are the
Suspension Switch and the Ride Condition Damper
Switch. The operator can quickly adjust the suspension
system to changing conditions with the touch of buttons.
(1) Suspension cylinder
BSuspension Switch
To avoid personal injury:
A Before using the suspension switch, make sure
the area near the machine is clear of all persons
and objects. The hydraulic pressure in the
suspension cylinders, accumulators or a valve
can cause the tractor and the attached
implement to move unexpectedly.
Using the front suspension switch, the following 3 modes
can be selected: ON, LOCK, and AUTO LOCK. While the
"ON" or "AUTO LOCK" is selected, the suspension
indicator is illuminated. In the "LOCK" mode, the indicator
is not illuminated.

OPERATING THE TRACTOR60
Example: Front End Loader operation (position
mode)
In order to efficiently perform Front End Loader work, the
suspension stays locked at lower speeds. This helps hold
the tractor in a stable condition. While traveling, the
suspension is turned on for comfortable ride.
Example: Plowing (draft mode)
When a drafted load becomes heavy, the suspension gets
locked. When the load becomes lighter, the suspension is
turned on. In moving with the plow up, the suspension is
kept on.

C Suspension "ON" Mode
Whether driving on roads or doing work, the ON mode
reacts to changing surface conditions and the changing
weight of the tractor as implements are used. The ON
mode is usually selected. When the ON mode is selected,
the suspension indicator is illuminated.
C Suspension "LOCK (OFF)" Mode
The suspension system is locked out, and no suspension
action takes place. The LOCK mode should be selected

with implements. Of the three modes (Normal mode, Firm
mode, Soft mode), Normal mode is generally
recommended for most tractor work.
BManual Control Mode
To avoid personal injury:
A Before releasing the manual control mode,
make sure the area near the machine is clear of
all persons and objects.
Because of the hydraulic pressure in the
cylinder, the machine height may change
unexpectedly or the suspension cylinder
adjustment control may get activated, which
affects the height and/or posture of the tractor
or the implement.
The tractor front end height can be raised or lowered by
moving the suspension cylinder in the manual control.
This is useful in attaching and detaching a front implement
or front weight.
C Height adjusting procedure
1. Hold down the top (Firm mode) or the bottom (Soft
mode) of the ride condition damper switch to the
second stage for more than 3 seconds, and the buzzer
starts beeping and the suspension indicator starts
flashing (two or so flashes every second). Now the
machine gets in the manual control mode.
2. Hold down the top (Firm mode) of the ride condition
damper switch to the second stage, and the height is
raised.
3. Hold down the bottom (Soft mode) of the ride condition
damper switch to the second stage, and the height is
lowered.
C Firm Mode
In Firm mode, the suspension damping is set one level
higher than Normal mode. As an example, the operator
would use Firm mode when working with heavy
implements to prevent "rocking" or excessive bouncing,
for example a heavy round bale in the loader.
C Soft Mode
In Soft mode, the suspension system is set one level
lower than Normal mode. As an example, the operator
would use Soft mode when traveling on uneven or rough
road surfaces to obtain a more comfortable ride.
A Depending on the tractor gross weight, the "Firm" and
"Soft" modes may work at nearly the same as the
"Normal" mode.

OPERATING THE TRACTOR62
C Releasing the manual control mode
Reposition the suspension switch (to "ON", "LOCK" or
"AUTO LOCK") to release the manual control mode.
When released, the modes pre-selected with the
suspension switch and the ride condition damper switch
are resumed.
A The manual control mode is cleared in any of the
following cases.
1. Stopping the engine (turning OFF the key switch).
2. Running the machine at higher than 5 km/h.
A Do not run or operate the machine with its height
raised or lowered (while the manual control mode is
selected). Otherwise it may get in trouble.
(1) Parking brake lever
(2) Release button
(A) "PULL"
A Even in the manual control mode, the suspension
works according to the mode selected with the
suspension switch.
A With the "LOCK" mode selected, the machine height
becomes stable and an implement may be easily
attached and detached.
A The manual-mode raising and lowering speed varies
depending on the mode selected with the suspension
switch.
PARKING
BParking
To avoid personal injury:
BEFORE DISMOUNTING TRACTOR
A ALWAYS SET PARKING BRAKE AND LOWER
ALL IMPLEMENTS TO THE GROUND.
Leaving transmission in gear with the engine
stopped will not prevent the tractor from
accidental rolling.
A STOP THE ENGINE AND REMOVE THE KEY.
1. Before getting off the tractor, disengage the PTO,
lower all implements, place all control levers in their
neutral positions, pull the parking brake lever up to
park, stop the engine and remove the key.
2. If it is necessary to park on an incline, be sure to chock
the wheels to prevent accidental rolling of the
machine.
A Do not leave your tractor in the rain. If it cannot be
avoided, cover the muffler pipe to prevent water
entering.
A On the tractors equipped with the front suspension,
the machine height may change depending on the
hydraulic oil temperature or other factors.
OPERATING TECHNIQUES
BDifferential Lock
To avoid personal injury due to loss of steering
control:
A Do not operate the tractor at high speed with
any differential lock engaged.
A Do not attempt to turn with the rear wheel
differential lock engaged.
A Be sure to release the rear wheel differential
lock before making a turn in field conditions.

OPERATING THE TRACTOR64
BOperating the Tractor on a Road
To avoid personal injury:
A To help assure straight line stops when driving
at transport speeds, lock the brake pedals
together. Uneven braking at road speeds could
cause the tractor to roll-over.
A When traveling on road with 3-point hitch
mounted implement attached, be sure to have
sufficient front weight on the tractor to
maintain steering ability.
Observe all local traffic and safety regulations.
Use the registration plate.
BOperating on Slopes and Rough Terrain
To avoid personal injury:
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.
1. Be sure wheel tread is adjusted to provide maximum
stability.
(See "WHEEL ADJUSTMENT" in "TIRES, WHEELS
AND BALLAST" section.)
2. Slow down for slopes, rough ground, and sharp turns,
especially when transporting heavy, rear mounted
equipment.
3. Before descending a slope, shift to a gear low enough
to control speed without using brakes.
(1) Registration plate
BTransport the Tractor Safely
1. The tractor, if damaged, must be carried on a truck.
Secure the tractor tightly with ropes.
2. Follow the instruction below when towing the tractor:
Otherwise, the tractor’s powertrain may get damaged.
A Set the all shift levers to "NEUTRAL" position.
A If possible, start engine and select 2WD, if creep
speed is fitted ensure that it is disengaged.
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.
