SAFE OPERATION
-1
SAFE 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. 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.
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.)
If the CAB or ROPS is loosened or removed for any
reason, make sure that all parts are reinstalled
correctly before operating the tractor.
Never modify or repair a ROPS because welding,
bending, drilling, grinding, or cutting may weaken the
structure.
A damaged CAB or ROPS structure must be replaced,
not repaired or revised.
If any structural member of the CAB or ROPS is
damaged, replace the entire structure at your local
KUBOTA Dealer.
(1) ROPS
(2) Seat belt
4. 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.
5. Do not operate the tractor or any implement attached
to it while under the influence of alcohol, medication,
controlled substances or while fatigued.
6. Carefully check the vicinity before operating tractor or
any implement attached to it. Check for overhead
clearance which may interfere with a CAB or ROPS.
Do not allow any bystanders around or near tractor
during operation.
7. Before allowing other people to use your tractor,
explain how to operate and have them read this
manual before operation.
8. 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.
9. Do not allow passengers to ride on any part of the
tractor at anytime. The operator must remain in the
tractor seat during operation.
10. 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.)
11. Keep your tractor clean. Dirt, grease, and trash build
up may contribute to fires and lead to personal injury.
12. Use only implements meeting the specifications listed
under "IMPLEMENT LIMITATIONS" in this manual or
implements approved by KUBOTA.
-2
SAFE OPERATION
13. 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.
14. 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.)
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) Rear wheels
(A) Tread Width
15. Do not modify the tractor. Unauthorized modification
may affect the function of the tractor, which may result
in personal injury.
2. OPERATING THE TRACTOR
(1) Drawbar
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.
2. Keep all shields and guards in place. Replace any that
are missing or damaged.
3. Avoid sudden starts. To avoid upsets, slow down
when turning, on uneven ground, and before stopping.
4. The tractor cannot turn with the differential locked and
attempting to do so could be dangerous.
5. 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.
6. Watch where you are going at all times. Watch for and
avoid obstacles. Be alert at row ends, near trees, and
other obstructions.
7. When working in groups, always let the others know
what you are going to do before you do it.
8. Never try to get on or off a moving tractor.
9. Do not stand between tractor and implement or trailed
vehicle unless parking brake is applied.
SAFE OPERATION
C Safety for children
Tragedy can occur if the operator is not alert to the
presence of children. Children generally are attracted to
machines and the work they do.
1. Never assume that children will remain where you last
saw them.
2. Keep children out of the work area and under the
watchful eye of another responsible adult.
3. Be alert and shut your machine down if children enter
the work area.
4. Never carry children on your machine. There is no safe
place for them to ride. They may fall off and be run
over or interfere with your control of the machine.
5. Never allow children to operate the machine even
under adult supervision.
6. Never allow children to play on the machine or on the
implement.
7. Use extra caution when backing up. Look behind and
down to make sure area is clear before moving.
8. When parking your machine if at all possible park on a
firm, flat and level surface; if not, park across a slope.
Set the parking brake(s), lower the implements to the
ground, remove the key from the ignition and lock the
cab door (if equipped) and chock the wheels.
C Operating on slopes
Slopes are a major factor related to loss-of-control and tipover accidents, which can result in severe injury or death.
All slopes require extra caution.
1. To avoid upsets, always back up steep slopes. If you
cannot back up the slope or if you feel uneasy on it, do
not operate on it. Stay off slopes too steep for safe
operation.
2. Driving forward out of a ditch, mired condition or up a
steep slope increases the risk of a tractor to be upset
backward. Always back out of these situations. Extra
caution is required with four-wheel drive models
because their increased traction can give the operator
false confidence in the tractor's ability to climb slopes.
3. Keep all movement on slopes slow and gradual. Do
not make sudden changes in speed, direction or apply
brake and make sudden motions of the steering
wheel.
4. Avoid disengaging the clutch or changing gears speed
when climbing or going down a slope. If on a slope
disengaging the clutch or changing gears to neutral
could cause loss of control.
5. Special attention should be made to the weight and
location of implements and loads as such will affect the
stability of the tractor.
6. To improve stability on slope, set widest wheel tread
as shown in "TIRES, WHEELS AND BALLAST"
section.
Follow recommendations for proper ballasting.
-3
C Driving the tractor on the road
1. Lock the two brake pedals together to help assure
straight-line stops. Uneven braking at road speeds
could cause the tractor to tip over.
(1) Brake Pedal (LH)
(2) Brake Pedal (RH)
(3) Brake Pedal Lock
(A) Whenever travelling on the road
2. Check the front wheel engagement. The braking
characteristics are different between two and four
wheel drive. Be aware of the difference and use
carefully.
3. Always slow the tractor down before turning. Turning
at high speed may tip the tractor over.
4. Make sure that the Slow Moving Vehicle (SMV) sign is
clean and visible. Use hazard lights and turn signals as
required.
(1) SMV emblem
(2) Bracket
5. Observe all local traffic and safety regulations.
6. Turn the headlights on.
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.
-4
SAFE OPERATION
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.
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) Safety chain
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, and
remove the key.
2. Make sure that the tractor has come to a complete
stop before dismounting.
3. Avoid parking on steep slopes, if at all possible park on
a firm and level surface; if not, park across a slope with
chock the wheels.
Failure to comply with this warning may allow the
tractor to move and could cause injury or death.
(1) PTO Shaft cover
(2) PTO Shaft cap
(A) "NORMAL POSITION"
(B) "RAISED POSITION"
3. Before installing or using PTO driven equipment, read
the manufacturer's manual and review the safety
labels attached to the equipment.
4. When operating stationary PTO driven equipment,
always apply the tractor parking brake and place
chocks behind and in front of the rear wheels. Stay
clear of all rotating parts. Never step over rotating
parts.
SAFE OPERATION
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. When transporting on the road, 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"
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

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.

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.
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.

SAFE OPERATION
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.

WARMING UP
To avoid personal injury:
A Be sure to set the parking brake during warmup.
A Be sure to set all shift levers to the "NEUTRAL"
positions and to place PTO lever in "OFF"
position during warm-up.
For five minutes after engine start-up, allow engine to
warm up without applying any load, this is to allow oil to
reach every engine part. If load should be applied to the
engine without this warm-up period, trouble such as
seizure, breakage or premature wear may develop.
BWarm-up Transmission Oil at Low
Ambient Temperatures
Hydraulic oil serves as transmission fluid. In cold weather,
the oil may be cold with increased viscosity. This can
cause delayed oil circulation or abnormally low hydraulic
pressure for some time after engine start-up. This in turn
can result in trouble in the hydraulic system. To prevent
the above, observe the following instructions:
Warm up the engine at about 50 % of rated rpm according
to the table below:
Ambient temperature
Warm-up time requirement
Above 0 C (32 F)
At least 5 minutes
0 to -10 C (32 to 14 F)

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.
OPERATING FOLDABLE ROPS
[Except B2320DTN, B2320HSDN]
To avoid personal injury:
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 pins.
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.

manner, step lightly on the brake pedals alternately.
BOperating the Tractor on a Road
To avoid personal injury:
A To help assure straight line stops when driving
at transport speeds, lock the brake pedals
together. Uneven braking at road speeds could
cause the tractor to roll-over.
A When traveling on road with 3-point hitch
mounted implement attached, be sure to have
sufficient front weight on the tractor to
maintain steering ability.
A Towed equipment (without brake) must not
exceed 1.5 times the tractor weight when
traveling on roads or at high speeds.
Be sure SMV emblem and hazard light are clean and
visible. If towed or rear-mounted equipment obstructs
these safety devices, install SMV emblem and hazard
light on equipment.
Consult your local KUBOTA dealer for further detail.
BOperating on Slopes or Rough Terrain
To avoid personal injury:
A Always back up when going up a steep slope.
Driving forward could cause the tractor to tip
over backward. Stay off hills and slopes too
steep for safe operation.
A Avoid changing gears when climbing or
descending a slope.
A If operating on a slope, never disengage the
clutch or shift levers to neutral. Doing so could
cause loss of control.
A Do not drive the tractor close to the edges of
ditches or banks which may collapse under the
weight of the tractor. Especially when the
ground is loose or wet.
1. Be sure wheel tread is adjusted to provide proper
stability.
(See "WHEEL ADJUSTMENT" in "TIRES, WHEELS
AMD BALLAST" section.)
2. Slow down for slopes, rough ground, or 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.
BDirections for Use of Power Steering
1. Power steering is activated only while the engine is
running. 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.

WHEEL ADJUSTMENT
To avoid personal injury:
A Do not attempt to mount a tire on a rim. This
should be done by a qualified person with the
proper equipment.
A Always maintain the correct tire pressure.
Do not inflate tires above the recommended
pressure shown in the operator's manual.
A Do not use tires other than those approved by
KUBOTA.
BInflation Pressure
Though the tire pressure is factory-set to the prescribed
level, it naturally drops slowly over the course of time.
Thus, check it regularly and inflate as necessary.
To avoid personal injury:
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.
A Never operate tractor with a loose rim, wheel,
or axle.

To avoid the possibility of battery explosion:
For the refillable type battery, follow the
instructions below.
A Do not use or charge the refillable type battery
if the fluid level is below the LOWER (lower limit
level) mark. Otherwise, the battery component
parts may prematurely deteriorate, which may
shorten the battery's service life or cause an
explosion. Check the fluid level regularly and
add distilled water as required so that the fluid
level is between the UPPER and LOWER levels.
To avoid personal injury:
A Never remove the vent caps while the engine is
running.
A Keep electrolyte away from eyes, hands and
clothes. If you are spattered with it, wash it
away completely with water immediately and
get medical attention.
A Wear eye protection and rubber gloves when
working around the battery.
The factory-installed battery is of non-refillable
type. If the indicator turns white, do not charge the
battery but replace it with new one.
Mishandling the battery shortens the service life and adds
to maintenance costs.

A When mixing the anti-freeze with water, the anti-freeze
mixing ratio is 50 %.
A Securely tighten radiator cap. If the cap is loose or
improperly fitted, water may leak out and the engine
could overheat.
BAnti-Freeze
To avoid personal injury:
A When using antifreeze, put on some protection
such as rubber gloves (Antifreeze contains
poison.).
A If it is swallowed, seek immediate medical help.
Do NOT make a person throw up unless told to
do so by poison control or a health care
professional. Use standard first aid and CPR
for signs of shock or cardiac arrest. Call your
local Poison Control Center or your local
emergency number for further assistance.
A When antifreeze comes in contact with the skin
or clothing, wash it off immediately.
A Do not mix different types of Antifreeze.
The mixture can produce chemical reaction
causing harmful substances.
A Antifreeze is extremely flammable and
explosive under certain conditions. Keep fire
and children away from antifreeze.
A When draining fluids from the engine, place
some container underneath the engine body.
A Do not pour waste onto the grounds, down a
drain, or into any water source.
A Also, observe the relevant environmental
protection regulations when disposing of
antifreeze.
Always use a 50/50 mix of long-life coolant and clean soft
water in KUBOTA engines.
Consult your local KUBOTA Dealer concerning coolant for
extreme conditions.
1. Long-life coolant (hereafter LLC) comes in several
types. Use ethylene glycol (EG) type for this engine.
2. Before employing LLC-mixed cooling water, fill the
radiator with fresh water and empty it again.
Repeat this procedure 2 or 3 times to clean up the
inside.
3. Mixing the LLC
Premix 50% LLC with 50% clean soft water. When
mixing, stir it up well, and then fill into the radiator.
4. The procedure for the mixing of water and antifreeze
differs according to the make of the antifreeze and the
ambient temperature. Refer to SAE J1034 standard,
more specifically also to SAE J814c.

D At 1.013 x 10 Pa (760mmHg) pressure (atmospheric).
A higher boiling point is obtained by using a radiator
pressure cap which permits the development of
pressure within the cooling system.
5. Adding the LLC
(1) Add only water if the mixture reduces in amount
by evaporation.
(2) If there is a mixture leak, add the LLC of the same
manufacturer and type in the same mixture
percentage.
D Never add any long-life coolant of different
manufacturer. (Different brands may have
different additive components, and the engine
may fail to perform as specified.)
6. When the LLC is mixed, do not employ any radiator
cleaning agent. The LLC contains anticorrosive agent.
If mixed with the cleaning agent, sludge may build up,
adversely affecting the engine parts.
7. Kubota's genuine long-life coolant has a service life of
2 years. Be sure to change the coolant every 2 years.
