SAFE OPERATION
-1SAFE OPERATION
TRACTOR
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 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 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 any portion may
weaken the structure.
A damaged ROPS structure must be replaced, not
repaired or revised. If any structural member of the
ROPS is damaged, replace the entire structure at your
local KUBOTA dealer.
5. Always use the seat belt if the tractor has a ROPS. Do
not use it if there is no ROPS. Check the seat belt
regularly and replace if frayed or damaged.
6. Do not operate the tractor or any implement attached
to it while under the influence of alcohol, medication,
controlled substances or while fatigued.
7. Carefully check the vicinity before operating tractor or
any implement attached to it. Check for overhead
clearance which may interfere with a ROPS. Do not
allow any bystanders around or near tractor during
operation.
8. Before allowing other people to use your tractor,
explain how to operate and have them read this
manual before operation.
9. 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.
10.Do not allow passengers to ride on any part of the
tractor at anytime. The operator must remain in the
tractor seat during operation.
11.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.)
12.Keep your tractor clean. Dirt, grease, and trash build
up may contribute to fires and lead to personal injury.
13.Use only implements meeting the specifications listed
under "IMPLEMENT LIMITATIONS" in this manual or
implements approved by KUBOTA.
14.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.
15.Do not modify the tractor. Unauthorized modification
may affect the function of the tractor, which may result
in personal injury.
(1) ROPS
(2) Seat belt
4. To ensure ROPS protection, do not operate tractor
without loader main frame.
SAFE OPERATION-2
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 ROPS.
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) Drawbar (option)
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.
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.
-3SAFE OPERATION
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 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 changing gears speed when climbing or going
down a slope. If on a slope 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.
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.
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. 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.
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.
(1) Safety chain
SAFE OPERATION-4
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.
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.
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
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"
(1) PTO Shaft cover
(2) PTO Shaft cap
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.
(A) "NORMAL POSITION"
(B) "RAISED POSITION"
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.
-5SAFE OPERATION
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.

SAFE OPERATION-6
LOADER
Most loader equipment accidents can be avoided by following simple safety precautions.
These safety precautions, if followed at all times, will help you operate your loader safely.
1. BEFORE OPERATING THE LOADER
1. Read and understand all instructions and precautions
found in both the tractor and the loader operator's
manuals before using the loader.
Lack of knowledge can lead to accidents.
2. It is the owner's responsibility to ensure that anyone
who will operate the loader reads this manual first and
becomes familiar with the safe operation of the loader.
3. For your safety, a ROPS with a seat belt is strongly
recommended by KUBOTA in almost all applications.
If the tractor is not equipped with ROPS, it should not
be operated in a situation where ROPS is
recommended. If you have any questions, consult
your local KUBOTA Dealer.
Always use the seat belt when the tractor is equipped
with a ROPS. Never use the seat belt when the tractor
is not equipped with a ROPS.
4. Visually check for hydraulic leaks and broken, missing,
or malfunctioning parts.
Make necessary repairs before operating.
5. Replace damaged or illegible safety labels. See
following pages for required labels.
6. Enter and exit the operator's seat only from left side of
the tractor.
7. Engage the loader control valve lock to prevent
accidental actuation when the implement is not in use
or during transport. Do not utilize the valve lock for
machine maintenance or repair.
8. Follow the precautions below when attaching
implements.
A Make sure both handles (LH, RH) contact the ear
plates at the points (A) and are all the way down.
A Make sure both lock pins (LH, RH) protrude through
the pin slots.
A Kubota recommends the use of Kubota attachments
on Kubota loaders. Non-Kubota attachments, if used,
must comply with ISO 24410, first edition 2005-04-15.
A Use of a non-Kubota attachment that does not comply
with ISO 24410 or the improper positioning of
handle(s) or non-protrusion of pin(s) may result in
detachment of the attachment or deformation, causing
loss of performance, personal injury or death.
(A) The handle contacts the ear
plate at the points.
2. OPERATING THE LOADER3. AFTER OPERATING THE LOADER
-7SAFE OPERATION
1. Operate the loader only when properly seated at the
controls. Do not operate from the ground.
2. Move and turn the tractor at low speeds.
3. Never allow anyone to get under the loader bucket or
reach through the boom when the bucket is raised.
4. Keep children, others and livestock away when
operating loader and tractor.
5. Do not walk or work under a raised loader bucket or
attachment unless it is securely blocked and held in
position.
6. For tractor stability and operator safety, rear ballast
must be added to the 3-point hitch and to the rear
wheels when using loader.
7. Exercise extra caution when operating the loader with
a raised bucket or attachment.
8. Do not lift or carry any person on the loader, in the
bucket, or other attachment.
9. Avoid loose fill, rocks and holes. They can be
dangerous for loader operation or movement.
10.Avoid overhead wires and obstacles when the loader
is raised. Contacting electric lines can cause
electrocution.
11.Gradually stop the loader boom when lowering or
lifting.
12.Use caution when handling loose or shiftable loads.
13.Using loaders for handling large, heavy, or shiftable
objects is not recommended without proper handling
attachments.
14.Handling large heavy objects can be extremely
dangerous due to :
A Danger of rolling the tractor over.
A Danger of upending the tractor.
A Danger of the object rolling or sliding down the
loader boom onto the operator.
15.If you must perform this sort of work (item 14), protect
yourself by :
A Never lift the load higher than necessary to clear
the ground.
A Add rear ballast to the tractor to compensate for the
load or use rear implement.
A Never lift large objects with equipment that may
permit them to roll back onto the operator.
A Move slowly and carefully, avoiding rough terrain.
16.Never lift or pull a load from any point on the loader
with a chain, rope, or cable. Doing so could cause a
rollover or serious damage to the loader.
17.Be extra careful when operating the tractor on a slope,
always operate up and down, never across the slope.
Do not operate on steep slopes or unstable surfaces.
18.Carry loader boom at a low position during transport.
(You should be able to see over the bucket.)
19.Allow for the loader length when making turns.
1. When loader work is complete and parking or storing,
choose flat and hard ground. Lower the loader boom
to the ground, stop the engine, set the brakes and
remove the key before leaving the tractor seat.
4. SERVICING THE LOADER
1. Always wear safety goggles when servicing or
repairing the machine.
2. Do not modify the loader. Unauthorized modification
may affect the function of the loader, which may result
in personal injury.
3. Do not use the loader as a work platform or a jack to
support the tractor for servicing or maintenance.
Securely support the tractor or any machine elements
with stands or suitable blocking before working
underneath.
For your safety, do not work under any hydraulically
supported devices. They can settle or suddenly leak
down or be accidentally lowered.
4. Escaping hydraulic oil under pressure can have
sufficient force to penetrate the skin, causing serious
personal injury. Do not use hands to search for
suspected leaks. If injured by escaping fluid, obtain
medical treatment immediately.
5. Do not tamper with the relief valve setting. The relief
valve is pre-set at the factory. Changing the setting
can cause overloading of the loader and tractor which
may result in serious personal injury.
6. When servicing or replacing pins in cylinder ends,
bucket, etc., always use a brass drift and hammer.
Failure to do so could result in injury from flying metal
fragments.

positions and to place PTO clutch lever 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.
OPERATING THE ENGINE16
To avoid personal injury or death:
A
Battery gases can explode. Keep cigarettes,
sparks, and flames away from battery.
A
If tractor battery is frozen, do not jump start
engine.
A
Do not connect the other end of the negative
(-) jumper cable to the negative (-) terminal of
the tractor battery.
When jump starting the engine, follow the instructions
below to safely start the engine.
1. Bring the helper vehicle with a battery of the same
voltage as disabled tractor within easy cable reach.
"THE VEHICLES MUST NOT TOUCH".
2. Engage the parking brakes of both vehicles and put
the shift levers in neutral. Shut both engines off.
3. Wear eye protection and rubber gloves.
4. Attach the red clamp to the positive (red, (+) or pos.)
terminal of the dead battery and clamp the other end
of the same cable to the positive (red, (+) or pos.)
terminal of the helper battery.
5. Clamp the other cable to the negative (black, (-) or
neg.) terminal of the helper battery.
6. Clamp the other end to the engine block or frame of
the disabled tractor as far from the dead battery as
possible.
BWarm-up Transmission Oil at Low
Temperature Range
Hydraulic oil serves as transmission fluid. In cold weather,
the oil may be cold with increased viscosity. This can
cause delayed oil circulation or abnormally low hydraulic
pressure for some time after engine start-up. This in turn
can result in trouble in the hydraulic system. To prevent
the above, observe the following instructions:
Warm up the engine at about 50% of rated rpm according
to the table below:
Ambient temperatureWarm-up time requirement
Above 0 C (32 F)At least 5 minutes
0 to -10 C (32 to 14 F)5 to 10 minutes
-10 to -20 C (14 to -4 F)10 to 15 minutes
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).

OPERATING THE TRACTOR
17OPERATING 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.
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.

OPERATING THE TRACTOR26
BOperating the Tractor on a Road
To avoid personal injury:
A To help assure straight line stops when driving
at transport speeds, interlock 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 and Rough Terrain
To avoid personal injury:
A Always back up when going up a steep slope.
Driving forward could cause the tractor to tip
over backward. Stay off hills and slopes too
steep for safe operation.
A Avoid changing gears when climbing or
descending a slope.
A If operating on a slope, never disengage 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. Slow down for slopes, rough ground, and sharp turns,
especially when transporting heavy, rear mounted
equipment.
2. Before descending a slope, be sure that the range
lever is in the low so that speed can be controlled
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.
The seat is reversible for backhoe operation. Follow the
procedure below to turn the seat around.
1. Slide the seat to the rearmost position.
2. Shift the range gear shift lever out of the "L" position.
3. Unlock the seat lock lever.
4. Turn the seat to counterclockwise for backhoe
operation.
The seat is automatically locked at the backhoe
position.
(1) Seat lock lever(A) "UNLOCK"
5. For tractor driving position, unlock the seat lock lever
and turn the seat clockwise.
A See "Operator's Seat" in "STARTING" when using
seat in driving position.
A To prevent damage to the lock lever or to release the
seat lock properly, do not attempt to pull up the lock
lever with extreme force while sitting on the seat. First
lift yourself from the seat, and then pull up the lock
lever.
28OPERATING THE LOADER
OPERATING THE LOADER
CONTROL LEVER
A When the lever is at each corner position marked by
asterisk (*), boom and bucket cylinders work at the
same time. However, the blank position (Raise & Roll
back) is not recommended for scooping because of
insufficient lift force.
To begin a test operation, slightly move the control lever
from the "N" position. Slowly raise the loader boom just
enough for the bucket to clear the ground when fully
dumped. Slowly work through the dump and roll back
cycles.
OPERATING THE LOADER
The loader should be operated with the tractor engine
speed depending on the application and the operator's
level of experience. Excessive speeds are dangerous,
and may cause bucket spillage and unnecessary strain on
the tractor and loader.
When operating in temperatures below -1(30), run
the tractor engine below 1200 rpm until the oil
temperature exceeds -1(30).
The following text and illustrations offer suggested loader
and tractor operating techniques.
To reduce the possibility of roll over:
A It is not recommended that the loader be
attached when operating another implement on
a hillside.
A When operating the loader in rough terrain, remove
the mower to avoid damage to the mower.
FILLING THE BUCKET
Approach and enter the pile with a level bucket.
A If the boom or bucket does not work in the directions
indicated on the label, lower the bucket to the ground,
stop the engine, and relieve all hydraulic pressure.
Recheck and correct all hydraulic connections.
Ease control lever toward you and then left to rollback and
lift the bucket.
The rollback and lifting of the bucket will increase
efficiency because a level bucket throughout the lifting
cycle resists bucket lift and increases breakaway effort.
A Do not be concerned if the bucket is not completely
filled during each pass. Maximum productivity is
determined by the amount of material loaded in a
given period of time. Time is lost if 2 or more attempts
are made to fill the bucket on each pass.
LIFTING THE LOAD
When lifting the load, keep the bucket positioned to avoid
spillage.
29OPERATING THE LOADER
CARRYING THE LOAD
Position the bucket just below the level of the tractor hood
for maximum stability and visibility, whether the bucket is
loaded or empty.
Use extreme care when operating the loader on a slope.
Keep the bucket as low as possible. This keeps the bucket
and tractor center of gravity low and will provide maximum
tractor stability.
To avoid serious personal injury:
A Be extra careful when working on inclines.
A When operating on a slope, always operate up
and down the slope, never across the slope.
To avoid serious personal injury:
A Do not attempt to lift bucket loads in excess of
the loader capacity.
A Before raising the bucket to full height, make
sure the tractor is on level ground. If not, it may
tip over, even if the tractor is not moving.
When transporting a load, keep the bucket as low as
possible to avoid tipping, in case a wheel drops in a rut.
OPERATING THE LOADER30
DUMPING THE BUCKET
Lift the bucket just high enough to clear the side of the
vehicle. Move the tractor in as close to the side of the
vehicle as possible, then dump the bucket.
LOWERING THE BUCKET
After the bucket is dumped, back away from the vehicle
while lowering and rolling back the bucket.
OPERATING WITH FLOAT CONTROL
During operation on hard surfaces, keep the bucket level
and put the lift control in the float position to permit the
bucket to float on the working surface.
If hydraulic down pressure is exerted on the bucket it will
wear faster than normal.
The float position will also avoid mixing of surface material
with stockpile material. The float position will reduce the
chance of surface gouging while removing snow or other
material, or when working with a blade.
LOADING FROM A BANK
Choose a forward gear that provides a safe ground speed
and power for loading.
To avoid serious personal injury:
A Be extra careful when working on inclines.
A When operating on a slope, always operate up
and down the slope, never across the slope.
A Loader lift and break-away capacity diminish as
loading height is increased.
Side cutting is a good technique for cutting down a big
pile. Wheel width should not exceed the bucket width for
this procedure.
If the pile sides are too high and liable to cause cave-in,
use the loader to break down the sides until a slot can be
cut over the top.
31OPERATING THE LOADER
PEELING AND SCRAPING
Use a slight bucket down angle, travel forward, and hold
the lift control forward to start the cut. Make a short cut
and break-out cleanly.
With the bucket level, start a cut at the notch
approximately 2 in. deep. Hold the depth by feathering the
bucket control to adjust the cutting edge up or down.
When the front tires enter the notch, adjust the boom
cylinder to maintain proper depth.
Another method for large dirt piles is to build a ramp to
approach the pile.
It is important to keep the bucket level when approaching
a bank or pile. This will help avoid gouging the work area.
Make additional passes until the desired depth is reached.
During each pass, use only the bucket control while at
working depth. This will allow you to concentrate on
controlling the bucket angle to maintain a precise cut.
OPERATING THE LOADER32
LOADING LOW TRUCKS OR SPREADERS
FROM A PILE
For faster loading, minimize the angle of turn and length
of run between pile and spreader.
Backgrade occasionally with a loaded bucket to keep the
work surface free of ruts and holes. Also, hold the lift
control forward so the full weight of the bucket is scraping
the ground. Use the heel of the bucket
A Do not use the bucket in the dumped position for
bulldozing. As shown above, this method will impose
severe shock loads on the dump-linkage, the bucket
cylinders, and the tractor.
Leave dirt in the bucket because dumping on each pass
wastes time.
Operate at right angles to the ditch. Taking as big a bite
as the tractor can handle.
BACKFILLING
Approach the pile with the bucket flat.
Poor operating methods will move less dirt and make it
more difficult to hold a level grade.
Leave dirt which drifts over the side of the bucket for final
cleanup.
Pile dirt on the high side for easier backfilling on a slope.
33OPERATING THE LOADER
HANDLING LARGE HEAVY OBJECTS
To avoid serious personal injury or death:

OPERATING THE LOADER34
ATTACHING ATTACHMENTS
This quick attach coupler is designed to be used with
Kubota attachments. Non-Kubota attachments, if used,
must comply with ISO 24410, first edition 2005-04-15.
This quick attach coupler allows the operator to change
easily without the use of tools.
To avoid serious personal injury or death:
A Use of a non-Kubota attachment that does not
comply with ISO24410 or the improper
positioning of handle(s) or non-protrusion of
pin(s) may result in detachment of the
attachment or deformation, causing loss of
performance, personal injury or death.
(1) Quick attach coupler
A Attachments should be located on a flat, firm surface
when attaching and detaching them from the quick
attach coupler.
1. To mount an attachment, pull the handles of the quick
attach coupler latching pins to the unlatched position.
The quick attach coupler handles must be all the way
up to ensure that the latching pins are fully retracted.
2. Position the tractor squarely in front of the attachment
and tilt the quick attach coupler forward with the bucket
cylinders.
To avoid serious injury or machine damage:
A Raise the boom only enough to latch the
attachment.
The attachment could swing off the quick
attach coupler.
5. When the attachment is properly seated in the saddle
and against the front of the quick attach coupler
mounting plate, turn off the engine and set the parking
brake. Push the quick attach coupler handles to the
fully latched position. Verify both latching pins are
completely engaged in the base of the attachment.
(1) Quick attach coupler
3. Ease the quick attach coupler mounting plate into the
saddle of the attachment.
4. Roll the quick attach coupler back using the bucket
cylinders and raise the boom slightly. The back of the
attachment should rest against the front of the quick
attach coupler mounting plate and the weight of the
attachment should be supported by the loader.
(1) Quick attach coupler handle
To avoid serious personal injury or death:
A The following engagement points are critical.
1) The lock pins of the quick attach coupler
have to protrude into and through the pin
slots of the attachment on both sides.
It is critical that the pins are in good
condition and without visible signs of wear
or damage and that the operator align the
loader quick attach coupler with the
attachment to allow the pins to go through
the pin slots.
2) Both handles have to be pushed down until
the handles contact the ear plates near the
points where the pin bolt goes through the
handle (A).
3) Do not operate the tractor or attachment
unless all of the above conditions are met.
35OPERATING THE LOADER
(1) Latch pins
(2) Quick attach coupler stopper
7. When attaching different attachments visually inspect
for broken or damaged pins. If broken or damaged
pins are found, replace before using. Use of broken
pins may result in attachment detachment or
deformation, causing loss of performance, personal
injury or death.
8. You are now ready to use the attached attachment. All
compatible attachments attach and detach using the
same method.
6. Visually verify when pushing the quick attach coupler
handles into locked position that the latch pins rotate
completely and are located underneath the stop of the
quick attach coupler.
(A) The handle contacts the ear
plate at the points.
To avoid serious injury or machine damage:
A Never operate or transport attachments which are
not attached completely.
A Always replace damaged hardware immediately.
DETACHING ATTACHMENTS

2. Lower the attachment to ground level with the
attachment slightly in the rolled back position. Stop the
engine and set the parking brake.
3. Pull the quick attach coupler handles to the unlatched
position to release the latching pins.
4. While sitting in the tractor operator's seat, start the
engine and slowly move the loader control lever to the
"DUMP" position until the attachment is pushed away
slightly from the quick attach coupler.
5. Lower the loader boom so that the quick attach coupler
mounting plate clears the attachment saddle.
6. Back away from the attachment slowly.
7. If an attachment is not going to be attached to the
quick attach coupler immediately, push the handles of
the quick attach coupler to the locked position to
prevent damage to the handle assembly.

To avoid personal injury or death:
A Do not attempt to mount a tire on a rim. This
should be done by a qualified person with the
proper equipment.
A Always maintain the correct tire pressure.
Do not inflate tires above the recommended
pressure shown in the operator's manual.
A Do not use tires other than those approved by
KUBOTA.
BInflation Pressure
Though the tire pressure is factory-set to the prescribed
level, it naturally drops slowly in the course of time. Thus,
check it everyday and inflate as necessary.
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 personal injury or death:
A Additional ballast will be needed for
transporting heavy implements. When the
implement is raised, drive slowly over rough
ground, regardless of how much ballast is
used.
A Do not fill the front wheels with liquid to
maintain steering control.
BFront Ballast
Heavy pulling and heavy rear mounted implements tend
to lift front wheels. Therefore do not remove the loader
from the tractor at all times to maintain steering control
and prevent tip over.
BRear Ballast
Add weight to rear wheels if needed to improve traction or
for stability. The amount of rear ballast should be matched
to job and the ballast should be removed when it is not
needed.
The weight should be added to the tractor in the form of
liquid ballast.
A When the BT820 backhoe is installed to the tractor,
rear ballast should be removed.
A Do not fill tires with water or solution more than 75% of
full capacity (to the valve stem level).

BChecking Battery Condition
To avoid the possibility of battery explosion:
For the refillable type battery, follow the
instructions below.
A Do not use or charge the refillable type battery
if the fluid level is below the LOWER (lower limit
level) mark. Otherwise, the battery component
parts may prematurely deteriorate, which may
shorten the battery's service life or cause an
explosion. Check the fluid level regularly and
add distilled water as required so that the fluid
level is between the UPPER and LOWER levels.
To avoid personal injury or death:
A Never remove the 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.

body.
3. To slow charge the battery, connect the battery
positive terminal to the charger positive terminal and
the negative to the negative, then recharge in the
normal manner.
4. A boost charge is only for emergencies. It will partially
charge the battery at a high rate and in a short time.
When using a boost-charged battery, it is necessary to
recharge the battery as early as possible.
Failure to do this will shorten the battery's service life.
5. When the specific gravity of electrolyte is between
1.27 and 1.29, the charging is completed.
6. When exchanging an old battery for a new one, use
battery of equal specification shown in TABLE 1.
This screen type spark arrester was examined, tested,
and qualified in accordance with the USDA Forest Service
Standard 5100-1c, "Spark Arresters for Internal
Combustion Engines" for the B26.
C Maintenance
The screen type spark arrester should be removed,
cleaned, and inspected after every 100 hours of use.
1. The spark arrester is located inside the end of the
exhaust pipe, and is fastened with one screw.
2. Unfasten the screw and remove the spark arrester.
3. Shake loosened particles out of the screen assembly
and lightly clean the screen with a wire brush. Soak in
solvent and again clean with wire brush if necessary.
4. If any breaks in the screen or weldments are
discovered, the assembly must be replaced.
5. Return the spark arrester to the exhaust outlet, align
the screw holes and refasten the screw.
A USDA approval requires clearance between spark
arrester sleeve and exhaust pipe to be no larger than
0.584 mm (0.023 in.).
C Installation
1. Insert provided spark arrester and align its screw
mount hole with a pre-drilled hole (O.D. 1/8") in the
muffler tail pipe. If there is no mounting hole, drill a 1/8"
hole 0.6" from the end of muffler tail pipe.

73PERIODIC SERVICE OF THE TRACTOR
BAnti-Freeze
To avoid personal injury or death:
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 ground, 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.

pressure within the cooling system.
PERIODIC SERVICE OF THE TRACTOR74
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.
A The above data represent industry standards that
necessitate a minimum glycol content in the
concentrated antifreeze.

BReplacing Fuse
The tractor electrical system is protected from potential
damage by fuses.
A blown fuse indicates that there is an overload or short
somewhere in the electrical system.
If any of the fuses should blow, replace with a new one of
the same capacity.
A Before replacing a blown fuse, determine why the fuse
blew and make any necessary repairs. Failure to
follow this procedure may result in serious damage to
the tractor electrical system. Refer to the
"TROUBLESHOOTING" section of this manual or your
local KUBOTA Dealer for specific information dealing
with electrical problems.

DAILY CHECKS
1. Daily before operation, check the tractor hydraulic fluid
To avoid serious personal injury:
A Escaping hydraulic fluid under pressure can
have sufficient force to penetrate skin, causing
serious personal injury. Before disconnecting
lines, be sure to relieve all pressure.
Before applying pressure to system, be sure all
connections are tight and that lines, tubes, and
hoses are not damaged. Fluid escaping from a
very small hole can be almost invisible. Use a
piece of cardboard or wood, rather than your
hands, to search for suspected leaks.
