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. A damaged CAB or ROPS structure must be replaced,
not repaired or revised.
6. If any structural member of the CAB or ROPS is
damaged, replace the entire structure at your local
KUBOTA Dealer.
SAFE OPERATION-2
7. 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.)
8. 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.
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.
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.
(1) ROPS
(2) Seat belt
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.
(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.
-3SAFE OPERATION
12.Do not stand between tractor and implement or trailed
vehicle unless parking brake is applied.
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.
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 2 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)

(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.
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. On public roads use the SMV emblem and hazard
lights, if required by local traffic and safety regulations.
6. Observe all local traffic and safety regulations.
7. Turn the headlights on. Dim them when meeting
another vehicle.
8. Drive at speeds that allow you to maintain control at all
times.
9. Do not apply the differential lock while traveling at road
speeds. The tractor may run out of control.
SAFE OPERATION-4
10.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.
11.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.
12.Do not operate an implement while the tractor is on the
road. Lock the 3-point hitch in the raised position.
13.Do not ride or stand on the step during operation.
Riding or standing there could result in being crushed
under the rear tire due to slippage or the step
fracturing or displacing due to unintended loading.
(1) Step
14.When towing other equipment, use a safety chain and
place an SMV emblem on it as well.
15.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.
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
-5SAFE OPERATION
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"
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.
(1) Groove
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 manufacturer.
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.
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.
SAFE OPERATION-6
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) Battery
10.Do not attempt to mount a tire on a rim. This should be
done by a qualified person with the proper equipment.
11.Always maintain the correct tire pressure. Do not
inflate tires above the recommended pressure shown
in the operator's manual.
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.
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.
(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/SCR muffler and its
surroundings clear of anything flammable and keep
clean at all times. [Selective Catalytic Reduction
(hereinafter called SCR)]
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.

OPERATING THE ENGINE
EXHAUST AFTERTREATMENT DEVICES
To avoid personal injury or death:
A Read and understand "Safe Operation" in the
front of this manual.
A Read and understand 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.
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.
BDual Exhaust Aftertreatment Devices
Particulate matter (PM) and black smoke contained in
exhaust gases are trapped and removed by the DPF
(Diesel Particulate Filter) muffler.
The SCR system then decomposes residual nitrogen
oxides (NOx) into harmless nitrogen (N2) and water
(H2O) for purification.
This dual exhaust gas purifying device provides for clean
exhaust gas at low fuel consumption.
13OPERATING THE ENGINE
DIESEL 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)
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 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 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 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.
A It is recommended to do the regenerating while the
engine is warm.
SELECTIVE CATALYTIC REDUCTION
(SCR) MUFFLER
BOutline of the SCR
The injector jets urea aqueous solution (DEF/AdBlue®)
into the muffler, and the solution is hydrolyzed with the
heat of exhaust gas to generate ammonia (NH3).
The ammonia generated thus is mixed with exhaust gas
by the SCR muffler. In this way, nitrogen oxides (NOx)
contained in exhaust gases are reduced by ammonia and
decomposed into nitrogen and water vapor.
(1) SCR muffler
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.
21OPERATING THE ENGINE
BDEF/AdBlue®
To avoid personal injury:
A The urea aqueous solution (DEF/AdBlue®) is
colorless, odorless and harmless.
If the solution gets on your skin, immediately
wash it away with water.
The DEF/AdBlue®, used as reducing agent of SCR, is a
32.5% urea aqueous solution.
No qualification for handling the urea aqueous solution is
needed. As well, the solution is not designated as a
hazardous material.
The product is available at gas stations, truck stops and
specialty shops. Be sure to use the genuine product only.
Do not use any poor-quality products, or the engine may
have trouble and be damaged.
BWarning Indication and its
Countermeasure
Before starting the day’s job, check the fluid level with the
DEF/AdBlue® gauge on the instrument panel.
If the fluid runs short during operation, the warning
indicator lights up. If you continue running the machine as
it is, the engine output will be limited by 50% or so. If
running is continued, the engine will be limited to idling.
For details, look at the table below.
These limitations are stipulated in conformity with the
emission controls of each country and territory.
(1) DEF/AdBlue® tank (Blue cap)
A On the North American market, the high-grade NOx
reducing agent called urea aqueous solution is sold in
the name of DEF (Diesel Exhaust Fluid). On the

protect the battery and the starter, make sure that the
starter is not continuously turned for more than 10
seconds.)
A DEF/AdBlue® freezes at temperatures below -11
(12 ). Even if it is frozen, the engine is not affected
at its start-up and running.
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 (-4 ).
(1) Heater indicator
A During a cold start, the low temperature regulation
indicator will appear on the LCD and the buzzer may
sound once every 2 seconds. In this case, the engine
speed will be limited to about 60%. If the operation is
continued, the engine speed limit will gradually and
automatically increase until the rotational speed will

OPERATING THE ENGINE30
WARMING UP
To avoid personal injury or death:
A Be sure to set the main gear shift lever to
"PARK" position and set the shuttle shift lever
to the "NEUTRAL" position and place the PTO
switch in the "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 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:
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)
Ambient temperature Warm-up time requirement
Higher than 0 (32 ) Approx. 5 minutes
0 to -10 (32 to 14 ) 10 to 20 minutes
-10 to -20 (14 to -4 ) 20 to 30 minutes
Below -20 (-4 ) More than 30 minutes
A Do not operate the tractor under full load condition until
it is sufficiently warmed up.
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".
(1) Dead battery
(2) Jumper cables
(3) Helper battery
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
31OPERATING 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.
OPERATING FOLDABLE ROPS
To avoid personal injury or death:
A When raising or folding the ROPS, apply
parking brake, stop the engine and remove the
key.
Always perform function from a stable position
at the rear of tractor.
A Fold the ROPS down only when absolutely
necessary and fold it up and lock it again as
soon as possible.
A Before proceeding to fold ROPS, check for any
possible interference with installed
implements and attachments.
If interference occurs, contact your KUBOTA
Dealer.
BTo Fold the ROPS
1. Remove both set bolts.
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.)

canceled.)
2. Return the hand throttle lever to the lowest speed
position.
3. Turn the key switch to "OFF".
BConstant RPM Management Control
Constant RPM Management can be turned "ON" or "OFF"
by operating the switch. Pressing the switch turns the
control "ON" and pressing the switch again 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’s 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.
53OPERATING THE TRACTOR
A The purpose of constant RPM management is not to
increase the engine power.
PARKING
BParking
To avoid personal injury or death:
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 to
parking position, 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.
(1) Constant RPM management switch with indicator
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 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.

OPERATING TECHNIQUES
BDifferential Lock
To avoid personal injury or death due to loss of
steering control:
A Do not operate the tractor at high speed with
differential lock engaged.
A Do not attempt to turn with the differential lock
engaged.
A Be sure to release the differential lock before
making a turn in field conditions.
If one of the rear wheels should slip, step on the
differential lock pedal. Both wheels will turn together, then
reduce slippage.
Differential lock is maintained only while the pedal is
depressed.
BOperating the Tractor on a Road
To avoid personal injury or death:
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.
A When traveling on road with trailer, you must
comply with local regulation at all time.
The maximum traveling speed with trailer is
provided by each country and regulated speed
may be different depend on the size of trailer
and type of trailer brake system.
Be sure SMV emblem and warning lamps are clean and
visible. If towed or rear-mounted equipment obstructs
these safety devices, install SMV emblem and warning
lamps on equipment.
Consult your local KUBOTA Dealer for further details.
(1) Differential lock pedal (A) Press to "ENGAGE"
(B) Release to "DISENGAGE"
A When using the differential lock, always slow the
engine down.
A To prevent damage to power train, do not engage

55OPERATING THE TRACTOR
BOperating on Slopes and Rough Terrain
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.
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.
BTrailer Electrical Outlet
A trailer electrical outlet is supplied for use with trailer or
implement.
(1) Trailer electrical outlet
C Function of each terminals in trailer electrical
outlet
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.

BPTO Gear Shift Lever
[if equipped]
To avoid personal injury or death:
A Be sure to observe the PTO shaft speed
prescribed for the individual implements. It is
extremely dangerous to run an implement at
high speed that is meant to be operated at low
speed. Use only when this higher rpm is
specifically recommended by the implement
manufacturer.
The PTO gear shift lever can be set to either 540 rpm or
540E rpm positions.
Move this lever to either position with the PTO clutch
control switch set to "OFF".
BPTO Speed Limiter
A Move the PTO gear shift lever (if equipped) to "540E"
and then turn on the PTO clutch control switch, and the
rev-limiter indicator lights up on the meter panel.
A If the PTO clutch control switch is turned on with the
engine rpm higher than the PTO 540E limit level, the
PTO clutch indicator on the meter panel starts blinking
and the PTO is disabled. After a while, the engine rpm
automatically drops below the PTO 540E limit level
and the PTO starts functioning. At the same time, the
flashing PTO clutch indicator stays "ON".
A If the PTO clutch control switch is turned "OFF" but the
engine rpm fails to rise with the throttle, return the
engine rpm to a lower level. This enables acceleration
again.

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.

BDraft Control
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.

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.

REMOTE HYDRAULIC CONTROL SYSTEM
The hydraulic auxiliary control valves can be installed up
to triple segments.
BRemote Control Valve
There are 2 types of remote valves available for these
models.
A Double acting valve with detents and self cancelling:
This valve may be placed in the detent mode. The
lever will stay in this position until the pressure reaches
a predetermined level or a cylinder reaches the end of
its stroke. Then it will automatically return to neutral.
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.
HYDRAULIC UNIT68
BRemote Control Valve Lever
The remote control valve lever directs pressurized oil flow
to the implement hydraulic system.

BRemote Control Valve Coupler
Connecting and Disconnecting
To avoid personal injury or death:
A Stop the engine and relieve pressure before
connecting or disconnecting lines.
A Do not use your hand to check for leaks.
C Connecting
1. Clean both couplers.
2. Remove dust plugs.
3. Insert the implement coupler to the tractor hydraulic
coupler.
4. Pull the implement coupler slightly to make sure
couplers are firmly connected.
C Disconnecting
1. Lower the implement first to the ground to release
hydraulic pressure in the hoses.
2. Clean the couplers.
3. Relieve pressure by moving hydraulic control levers
with engine shut off. Pull the hose straight from the
hydraulic coupler to release it.
4. Clean oil and dust from the coupler, then replace the
dust plugs.
BFlow Control Valve (option)
The optional flow control valve may be added for the
following purposes.
1. To operate within limits, the remote control valve (2)
above the flow control valve (3) and the 3-point hitch
at the same time without one affecting the other.
2. To operate within limits, the remote control valve (2)
above the flow control valve (3) and the other remote
control valve (1) at the same time without one affecting
the other. Activating the remote control valve (1) will
interrupt the operation of the 3-point hitch.
3. To maintain within limits, the constant speed of an
attachment (hydraulic motor RPM, for example) when
connected to the remote control valve (2) above the
flow control valve (3).
A At slower engine speeds the total hydraulic flow rate
may be inadequate for simultaneous operation of the
remote control valve (2) and the 3-point hitch or the
remote control valve (1), or operation of an attachment
connected to the remote control valves (1)(2). Under
these conditions, the engine speed must be increased
to provide additional hydraulic flow.
BAdjusting the flow rate
A Your local KUBOTA Dealer can supply parts to adapt
couplers to hydraulic hoses.
To avoid the possibility of personal injury or death
be aware of the following when making
adjustments:
A The 3-point hitch operation is influenced by the
combination of the adjustment of the flow
control valve and the engine speed.
A The 3-point hitch may rise slowly or not at all at
low engine rpm.
A The 3-point hitch may rise suddenly if engine
rpm is increased, or, flow control adjustment is
changed.
Refer to the illustration below.
1. The flow rate for the remote control valve (2), located
on above the flow control valve (3), can be adjusted.
2. Turn the flow control knob (4) counterclockwise (A),
and the flow rate for the remote control valve (2)
increases. A clockwise turn (B) of the knob causes the
flow to decrease. If the knob is turned all the way (C),
there will be no flow.
3. To adjust the flow rate, set the engine speed to the
operating RPM, turn the flow control knob once all the
way clockwise (C), and then turn it gradually
counterclockwise until a required flow rate is reached.
HYDRAULIC UNIT70
A Full adjustment of the valve will occur in approximately
1 1/2 revolutions of the flow control knob. Turning the
flow control knob beyond this point will have no affect
on the flow rate.
A When there is no need to adjust the flow rate, turn the
flow control knob all the way counterclockwise and
keep it in this position.

maintained at a constant level.
2. The remote control valve (2) and the 3-point hitch can
be operated at the same time with the speed of the 3point being influenced by the adjustment range of the
flow control valve.
3. Remote control valves (1) and (2) can be operated at
the same time with operation of the 3-point hitch being
interrupted by activation of valve (1).
4. The operation of valve (1) is influenced by the flow
adjustment to valve (2).
5. The 3-point hitch lift speed and the flow available for
valve (1) are influenced by the flow adjustment of valve
(2).
BPositions and advantages of the flow
control valve
Refer to illustration below.
C Position 1
1. The attachment control speed (hydraulic motor RPM,
for example) of the remote control valve (1) can be
maintained at a constant level within limits.

TIRES, WHEELS AND BALLAST
TIRES
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.
A When optional different-diameter tires are fitted on the
machine, the travel speed display mode must be
changed. Otherwise the travel speed will not get
correctly displayed. Such mode switching is also
needed when the original tires are back on the
machine.
(See "LCD MONITOR" in "OPERATING THE
TRACTOR" section.)
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.
WHEEL ADJUSTMENT
To avoid personal injury or death:
A When working on slopes or when working with
trailer, set the wheel tread as wide as practical
for maximum stability.
A Support tractor securely on stands before
removing a wheel.
A Do not work under any hydraulically supported
devices. They can settle, suddenly leak down,
or be accidentally lowered. If necessary to work
under tractor or any machine elements for
servicing or adjustment, securely support them
with stands or suitable blocking beforehand.
