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. 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.
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.
-3SAFE OPERATION
C Instructional seat (if equipped)
1. Always wear your seat belt and stabilize your body by
holding the handrail on the CAB frame.
2. It is not intended to carry children nor any other person
for any other purpose.
3. The left hand door must be closed at all time whenever
the instructional seat is occupied and the tractor is in
motion.
4. Do not permit others to ride, except on the designated
instructional seat.
5. Use caution to avoid the risks of obstructing operator's
view, falling from the machine and interfering with
controls.
6. Do not start and stop the tractor suddenly, nor take
sharp turn.
7. Do not use the instructional seat if the seat belt or the
door lock fails to function.
8. Do not use the instructional seat for transport.
9. When opening and closing the door from the
instructional-seat-sitting position, move the door
slowly. This is to prevent his or her hand(s) from
getting caught by the door or his or her body to hit
against the door.
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.
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.
SAFE OPERATION-4
4. Make sure that the Slow Moving Vehicle (SMV) sign is
clean and visible. Use hazard lights and turn signals as
required.
(1) SMV emblem
(2) Bracket
(1) 3-point hitch lowering lock lever(A) "LOCK"
(B) "UNLOCK"
5. Observe all local traffic and safety regulations.
6. Turn the headlights on. Dim them when meeting
another vehicle.
7. Drive at speeds that allow you to maintain control at all
times.
8. Do not apply the differential lock while traveling at road
speeds. The tractor may run out of control.
9. Avoid sudden motions of the steering wheel as they
can lead to a dangerous loss of stability. The risk is
especially great when the tractor is traveling at road
speeds.
10.Do not operate an implement while the tractor is on the
road. Lock the 3-point hitch in the raised position.
11.When towing other equipment, use a safety chain and
place an SMV emblem on it as well.
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
12.Set the implement lowering control in the "LOCK"
position to hold the implement in the raised position.
-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.
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
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.)
SAFE OPERATION-6
6. Keep first aid kit and fire extinguisher handy at all
times.
7. Disconnect the battery's ground cable before working
on or near electric components.
8. To avoid the possibility of battery explosion, do not use
or charge the refillable type battery if the fluid level is
below the LOWER ( lower limit level ) mark. Check the
fluid level regularly and add distilled water as required
so that the fluid level is between the UPPER and
LOWER levels.
9. To avoid sparks from an accidental short circuit,
always disconnect the battery's ground cable (-) first
and reconnect it last.
(1) Battery
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.
(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.
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
-7SAFE OPERATION
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 the 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/SCR muffler and its
surroundings clear of anything flammable and keep
clean at all times. [Selective Catalytic Reduction
(hereinafter called SCR)]
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
EXHAUST AFTERTREATMENT DEVICES
To avoid personal injury or death:
A Read "Safe Operation" in the front of this
manual.
A Read the danger, warning and caution labels
located on the tractor.
A To avoid the danger of exhaust fume
poisoning, do not operate the engine in a
closed building without proper ventilation.
A Never start engine while standing on ground.
Start engine only from operator's seat.
A Make it a rule to set all shift levers to the
"NEUTRAL" positions and to place PTO clutch
control switch in "OFF" position before starting
the engine.
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].
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.
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.
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
OPERATING THE ENGINE14
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
(Make sure that the DPF INHIBIT switch lamp is "OFF".)
Switch lamp OFF: Auto Regeneration Mode activated.
Switch lamp ON: Regeneration Inhibit Mode activated.
A When the engine is started, the "Auto Regeneration" mode is automatically activated.
A "Regeneration Inhibit" mode is activated, when the DPF INHIBIT switch is pushed after the engine is started.
When the regeneration indicator starts flashing:
2.
A specific amount of PM has built up in the DPF.
Continue to operate the tractor, and the regeneration process will begin automatically, make sure the working place
is in a safe area as DPF and exhaust temperature will rise.
When the engine rpm increase indicator starts flashing:
3.
Keep on working and increase the engine rpm until the indicator turns "OFF".
A Even if the Auto Regeneration Mode is selected, DPF regeneration may not begin because system requirements have
not been satisfied.
A The engine rpm increase indicator is used as a guide to satisfy the regeneration conditions. If the engine load is too
heavy, the engine rpm increase indicator may continue to flash, even though regeneration system conditions are
satisfied and regeneration may begin automatically. (See the "Tips on Diesel Particulate Filter [DPF] Regeneration")
16OPERATING THE ENGINE
C PM Warning Level and Required Procedures

(e.g. P208B: The code beginning with the letter "P" or "U" is the DTC)
21OPERATING THE ENGINE
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.
OPERATING THE ENGINE22
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
European and Japanese markets, it is on sale under
the trade name of AdBlue®.

If a DTC appears, immediately contact your local
KUBOTA Dealer.
A When operating in cold weather, the DEF/AdBlue® is
automatically thawed while the engine is running.
However, in weather conditions of under -30 (22), the DEF/AdBlue® cannot be completely
thawed and thus, a DTC(P208B) appears on the
instrument panel’s LCD screen.
If the DTC(P208B) appears on the screen, stop the
engine and restart it after 10 seconds. After restarting
the engine, the DTC(P208B) will disappear and the
thawing of the DEF/AdBlue® will resume.
In case the DTC(P208B) remains on the screen even
after restarting the engine several times, contact your
local KUBOTA Dealer.

except when the PTO clutch control switch is placed in
the "OFF" position and power shift / range shift lever is
placed in the "NEUTRAL" position.
10. Check to see that all the indicators on
the Easy Checker(TM) are "OFF".
If an indicator is still on, immediately stop the engine and
determine the cause.
C Indicators that will turn off after starting the engine
are: (1),(2),(3),(4),(5)
(1) Hydraulic control lever
(2) 3-P. Quick lower switch
(1) 3-P. Lifting / Lowering indicator
A The implement does not go down if the 3-point hitch is
"LOCKED" with 3-point hitch lowering lock lever.
(For details, see "3-Point Hitch Lowering Lock Lever"
in "3-POINT HITCH CONTROL SYSTEM" in

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).
STOPPING THE ENGINE
(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
match the Foot throttle (or Hand throttle) strength.
1. After slowing the engine to idle, wait 3 to
5 minutes for turbo to slow down and
then turn the key to "OFF".
2. Remove the key.
A When the engine is stopped-shutdown, DEF/AdBlue®
flow is reversed in the DEF/AdBlue® lines and related
piping and returned back into the DEF/AdBlue® tank
after cooling the DEF/AdBlue® injector.
The SCR system continues working several minutes
after engine shutdown to complete this purge process.
A Do not turn the machine main battery power off to the
engine until the DEF/AdBlue® return cycle purge
process is completed. Turning off the main battery
power to the engine and aftertreatment system prior to
completion may damage the system or cause it to
malfunction.

33OPERATING THE ENGINE
WARMING UP
To avoid personal injury or death:
A Be sure to set the parking brake during warm-
up.
A Be sure to set all shift levers to the "NEUTRAL"
positions and to place PTO switch in "OFF"
position during warm-up.
For 5 minutes after engine start-up, allow engine to warm
up without applying any load, this is to allow oil to reach
every engine part. If load should be applied to the engine
without this warm-up period, trouble such as seizure,
breakage or premature wear may develop.
BWarm-up 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:
1. Bring the helper vehicle with a battery of the same
voltage as disabled tractor within easy cable reach.
"THE VEHICLES MUST NOT TOUCH".
2. Engage the parking brakes of both vehicles and put
the shift levers in neutral. Shut both engines off.
3. Wear eye protection and rubber gloves.
4. Attach the red clamp to the positive (red, (+) or pos.)
terminal of the dead battery and clamp the other end
of the same cable to the positive (red, (+) or pos.)
terminal of the helper battery.
5. Clamp the other cable to the negative (black, (-) or
neg.) terminal of the helper battery.
6. Clamp the other end to the engine block or frame of
the disabled tractor as far from the dead battery as
possible.
7. Start the helper vehicle and let its engine run for a few
moments. Start the disabled tractor.
8. Disconnect the jumper cables in the exact reverse
order of attachment. (Steps 6, 5 and 4).
Ambient temperatureWarm-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) 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.
Charge the battery fully enough before operating the
tractor.
Otherwise the tractor might malfunction.
34OPERATING 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.

stays "DISENGAGED", however, the speeds change
themselves continuously. (1st to 8th or 8th to 1st)
5. Main gear shift speed memory function:
Suppose that a job was done at a travel speed, the
speed range (L, M, H) was changed and then the
original speed range was returned. The memory
function serves to automatically pick up the previously
selected main gear number.
Only when the speed range is “H” and the main gear
shift is somewhere between Speed 4 (20th) and
Speed 8 (24th), however, the “H-3” speed (19th) is
automatically selected.

OPERATING THE TRACTOR44
BDHC switch
On this tractor, the engine load and other fluctuations are
sensed and the speed is well controlled in response to the
loads. Turn the DHC switch "ON" when using a traction
PTO attachment (baler, etc.) on a slope. A well responsive
speed control can be expected. In other applications, turn
this switch "OFF". Smooth speed change is available for
comfortable ride.
(1) DHC switch(A) "Push to ON"
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 or death:
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 (6.8 mph).
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 (6.8 mph) and use the shuttle lever.
(2) Stop the tractor first and bring the shuttle lever
back to the original position.
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".
(1) Shuttle lever(F) "FORWARD"
(N) "NEUTRAL"
(R) "REVERSE"
A While the shuttle shift lever is at the "NEUTRAL"
position, the "N" character appears on the LCD
monitor.
(N) "NEUTRAL"
45OPERATING THE TRACTOR
To avoid personal injury or death:
A When you leave the tractor, be sure to apply the
parking brake and stop the engine.
A IN APPLYING THE BRAKES:
A The torque of the wheel axle is extremely
high while creep speed is being used. Be
sure to step down on the clutch pedal
completely before applying the brakes, or
the torque will overcome the brakes.
A When starting to operate the tractor, be sure
to release the parking brakes.
Misuse of the brakes may cause damage to
the transmission and is therefore not
acceptable to KUBOTA for coverage under
the warranty.
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.
(1) Creep Lever(A) "LOW".....Creep ON
(B) "HIGH".............Creep OFF
C Creep speed should be used only when doing one
of the following jobs:
1. Deep rotary-tilling and harrowing
2. Planting
3. Turf application
C Creep speed can not be used for any of the
followings:
1. Pulling a trailer
2. Front-loader operation
3. Front-blade operation
4. Earth-moving
5. Entering and leaving a field
6. Loading onto and unloading from a truck
A Press the clutch pedal completely down and stop the
tractor's motion before shifting the range gear shift
lever.
B4WD / Auto 4WD Switch
To avoid personal injury or death:
A Do not engage the front wheel drive when
traveling at road speed.
A When driving on icy, wet, or loose surfaces,
make sure the tractor is correctly ballasted to
avoid skidding and loss of steering control.
Operate at reduced speed and engage front
wheel drive.
A 4WD model tractor is equipped with 4 wheel
braking and appropriate care should be taken
during hard braking.
A An accident may occur if the tractor is
suddenly braked, such as by heavy towed
loads shifting forward or loss of control.
A The braking characteristics are different
between 2 and 4-wheel drive tractor models. Be
aware of the difference and use carefully.
Press the left half;
The 4WD mode activates.
The 4WD indicator comes on.

6. In regards to rolling resistance, it is possible to reduce
tire wear and to save fuel.
7. Taking corners at high speeds can be done
effortlessly.
A Tires will wear quickly if the front wheel drive is
engaged on paved roads.
BBi-speed Turn Switch
To avoid personal injury or death:
A Do not use "Bi-speed Turn" at high speed.
A "Bi-speed Turn" enables short and fast turns,
therefore, become familiar with its performance
before operating in close or confined areas.
A This switch can be operated when the tractor is on the
go or at rest without depressing the clutch.
A Bi-speed turn system works when you press the "Bi-
speed turn switch" and the front tire (inside of the turn)
exceeds 35 degrees.
Bi-speed turn makes the front tire speed 1.6 times
faster than the standard 4WD front tire speed.
A "Bi-speed Turn" operates only when the travel speed
is "H-3 (19th)" or lower and the tractor travel speed is
10 km/h (6.2 mph) or less at the start of the turn.
A If the "Bi-speed Turn" indicator is flashing, then Bi-
speed Turn will not operate.
C Bi-speed turn use is effective for the following
jobs:
1. Turning at the end of rows. (planting, cultivating,
harrowing.)
2. Increasing maneuverability when working in tight
spaces.
A Tires will wear quickly if the front wheel drive is
engaged on paved roads.

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
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 2 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.
64OPERATING 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.

FRONT SUSPENSION
To avoid personal injury or death:
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 or death:
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.

(C) Suspension "AUTO LOCK"
OPERATING THE TRACTOR72
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.
(1) Suspension indicator
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
when the operator needs to prevent the tractor and the
attached implements from overcompensating the front
suspension system. The suspension indicator does not
illuminate when the LOCK mode is selected.
