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
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.
PRECAUTIONS BEFORE
OPERATING THE TRACTOR
Know your equipment and its limitations.
Read this entire manual before starting and operating
the tractor.
1. General precautions
• Pay special attention to the safety labels on the
tractor.
• Do not operate the tractor or any implement
attached to the tractor while under the influence of
alcohol, medication, controlled substances, or while
you are fatigued.
• Before allowing other people to use your tractor,
explain them how to operate it and require them to
read this manual before operating it.
• Never wear loose, torn, or bulky clothing around the
tractor. Loose, torn, or bulky clothing may catch on
moving parts or controls, leading to the risk of an
accident. Use additional safety items: hard hat,
safety boots or shoes, eye and hearing protection,
gloves, and so on, as appropriate or required.
• Do not allow passengers to ride on any part of the
tractor at any time. The operator must remain in the
tractor seat during operating the tractor.
• 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 SERVICE INTERVALS on
page 115)
• Keep your tractor clean. Buildup of dirt, grease, and
trash may contribute to fires and lead to personal
injury.
• Use only implements meeting the specifications
listed under IMPLEMENT LIMITATION TABLES on
page 27, or implements approved by KUBOTA.
• 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 maintain proper ballast and braking.
Follow the safe operating procedures specified in
the implement manual or the attachment manual.
• 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 WHEEL ADJUSTMENT on page 97)
(1) Rear wheels (A) Tread width
• Do not modify the tractor. Unauthorized
modification may affect the function of the tractor,
which may result in personal injury.
2. Precautions for CAB and ROPS
KUBOTA recommends the use of a CAB or roll-over-
protective-structures (ROPS), and seat belt in almost
all applications. Combination of a CAB or ROPS and
seat belt will reduce the risk of serious injury or death if
the tractor should be upset.
• Check for overhead clearance which may interfere
with a CAB or ROPS.
• Set the parking brake and stop the engine. Remove
any obstructions which may prevent raising or
folding the ROPS. Do not allow any bystander.
Always perform functions of CAB or ROPS from a
stable position at the rear of the tractor. Hold the
top of the ROPS securely when raising or folding it.
Make sure that all pins are installed and locked.
• 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 any structural member of a
CAB or ROPS because welding, bending, drilling,
grinding, or cutting it may weaken the structure.
SAFE OPERATION
MX5400,MX6000
7

• If any structural member of the CAB or ROPS is
damaged, replace the entire structure at your local
KUBOTA Dealer.
• If the tractor is equipped with a foldable ROPS, you
may fold down it temporarily only when absolutely
necessary to fold down it for areas with constraints
on height.
There is no protection of operator provided by the
ROPS in the folded position. For operator safety,
you should place the ROPS in the upright and
locked position and fasten the seat belt for all other
operations.
• Always use the seat belt if the tractor has a CAB or
ROPS.
Do not use the seat belt if the foldable ROPS is
being folded or if there is no ROPS. Check the seat
belt regularly and replace if frayed or damaged.

(2) Seat belt
(3) CAB
PRECAUTIONS FOR
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,
and so on.
This manual sets forth some of the obvious risks, but
the list of risks is not exhaustive, and the list of risks
cannot be exhaustive. It is the operator's responsibility
to be alert for any equipment or environmental
condition that could compromise safe operation.
1. Precautions for starting to operate
the tractor
• Always sit in the operator's seat when starting the
engine or operating levers or controls. Adjust the
operator's seat according to Operator's seat on
page 42. Never start the engine while you are
standing on the ground.
• KUBOTA recommends that you get on and off the
tractor from the left side only. However, in the event
of an emergency, you may exit using the right-side-
door.
Be cautious when using the emergency-right-side-
door, as there are no steps from the CAB to the
ground on the right side.
• 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 is equipped with a
CAB or a foldable ROPS in the upright and locked
position.
• Do not start the engine by shorting across starter
terminals or bypassing the safety-start-switch. The
tractor may start in gear and move if normal starting
circuitry is bypassed.
• Do not operate or idle the engine in a non-
ventilated area. Carbon monoxide gas is colorless,
odorless, and deadly.
• Check that the operator-presence-control-system
(OPC) are functioning correctly before each time
you use the tractor. Test the safety systems.
–[Manual transmission type]
See Checking the engine start system [Manual
transmission type] on page 131 and Checking
the operator presence control on page 132.
–[HST type]
See Checking the engine start system [HST
type] on page 132 and Checking the operator
presence control on page 132.
Do not operate unless they are functioning
correctly.
2. Precautions for working the
tractor
• Pull only from the drawbar. Never hitch to axle
housing or any other point except drawbar. Hitching
to axle housing or any other point except drawbar
SAFE OPERATION
8
MX5400,MX6000

will increase the risk of serious personal injury or
death due to a tractor upset.
(1) Drawbar
• For trailing the PTO-driven implements, set the
drawbar to the towing position.
• Attach pulled or towed loads to the drawbar only.
• Keep all shields and guards in place. Replace any
shield or guard that are missing or damaged.
• Avoid sudden starts. To avoid upsets, slow down
when turning, on uneven ground, and before
stopping.
• The tractor cannot turn with the differential locked.
Do not attempt to turn with the differential locked
because it could be dangerous.
• Do not operate near ditches, holes, embankments,
or other ground surface features which may
collapse under the weight of the tractor. The risk of
tractor upset is even higher when the ground is
loose or wet. Tall grass can hide obstacles, so walk
the area first to be sure.
• Watch where you are going at all times. Watch for
and avoid obstacles. Be alert at row ends, near
trees, and other obstructions.
• When working in groups, always let the others
know what you are going to perform before you
perform it.
• Never try to get on or off a moving tractor.
• Always sit in the operator's seat when you are
operating levers or controls.
• Do not stand between the tractor and the
implement or the trailed vehicle unless parking
brake is applied.
3. Safety for children
Tragedy can occur if the operator is not alert to the
presence of children. Children generally are attracted to
machines and their work.
• Never assume that children will remain where you
last saw them.
• Keep children out of the work area and under the
watchful eye of another responsible adult.
• Be alert and shut the tractor down if children enter
the work area.
• Never carry children on the tractor. There is no safe
place for them to ride. They may fall off and be run
over or interfere with your control of the tractor.
• Never allow children to operate the tractor even
under adult supervision.
• Never allow children to play on the tractor or on the
implement.
• Use extra caution when the tractor is backing up.
Before the tractor starts to move, look down and
behind to make sure that the working area is clear.
4. Avoiding crystalline silica (quartz)
dust
To avoid serious injury or death from silica dust:
• Avoid exposure to dust containing crystalline silica
particles.
This dust can cause serious injury to the lungs
(silicosis).
Because crystalline silica is a basic component of
sand and granite, many activities at construction
sites produce dust containing crystalline silica.
Trenching, sawing and boring of material containing
crystalline silica can produce dust containing
crystalline silica.
• If dust which contains crystalline silica is present,
there are guidelines which should be followed:
– Be aware of the potential health effects of
crystalline silica and that smoking may add to
the damage.
– Be aware of and follow OSHA (or other local,
State or Federal) guidelines for exposure to
airborne crystalline silica.
– Know the work operations where exposure to
crystalline silica may occur.
– Participate in air monitoring or training
programs offered by the employer.
– Be aware of and use optional equipment
controls such as water sprays, local exhaust
ventilation, and enclosed CABs with positive
pressure air conditioning, if the machine has
SAFE OPERATION
MX5400,MX6000
9

such equipment. Otherwise respirators shall be
worn.
– Where respirators are required, wear a
respirator approved for protection against
crystalline silica containing dust. Do not alter
the respirator in any way. Workers who use
tight-fitting respirators cannot have beards/
mustaches which interfere with the respirator
seal to the face.
– If possible, change into disposable or washable
work clothes at the work site; shower and
change into clean clothing before leaving the
work site.
– Do not eat, drink, use tobacco products, or
apply cosmetics in areas where there is dust
containing crystalline silica.
– Store food, drink and personal belongings away
from the work area.
– Wash hands and face before eating, drinking,
smoking, or applying cosmetics after leaving
the exposure area.
5. Precautions for operating the
tractor on slopes
Slopes are a major factor related to loss-of-control and
tip-over accidents, which can result in severe injury or
death.
All slopes require extra caution.
• To avoid upsets of the tractor, always back it up
steep slopes. If you cannot back the tractor up on
the slope or if you feel uneasy to back it up on the
slope, do not operate on it. Stay off slopes too
steep for safe operation.
• Driving forward out of a ditch, mired condition or up
a steep slope increases the risk of the tractor to be
upset backward. Always back the tractor out of a
ditch, mired condition or steep slope. The 4-wheel
drive models require extra caution because their
increased traction can give the operator false
confidence in the ability of the tractor to climb
slopes.
• Keep all movement of the tractor on slopes slow
and gradual. Do not change speed or direction of
the tractor suddenly. Do not apply brake suddenly.
Do not move the steering wheel suddenly.
• Avoid disengaging the clutch or changing gears
speed when the tractor is climbing or going down a
slope. If operating the tractor on a slope,
disengaging the clutch or changing gears to neutral
could cause loss of control.
• You should pay special attention to the weight and
location of implements and loads because they will
affect the stability of the tractor.
• To improve stability of the tractor on slope, set the
widest wheel tread.
(See WHEEL ADJUSTMENT on page 97)
Follow recommendations for proper ballasting.
(See BALLAST on page 102)
6. Precautions for driving the tractor
on the road
• Lock the two brake pedals together to help assure
straight-line stops. Uneven braking at road speeds
could cause the tractor to tip over.
[Manual transmission type]
[HST type]
(1) Brake pedal (LH)
(2) Brake pedal (RH)
(3) Brake pedal lock
(A) Whenever traveling on the
road
• Check the engagement of front wheel. The braking
characteristics are different between 2-wheel drive
and 4-wheel drive. Know the difference and use
carefully.
• Always slow the tractor down before turning.
Turning at high speed may tip the tractor over.
• Make sure that the slow-moving vehicle (SMV) sign
is clean and visible. Use the hazard lights and turn
signals as required.
• Close the rear window to maintain the visibility of
the SMV emblem.

(A) Close
• Follow all local traffic and safety regulations.
• Turn the headlights on. Dim the headlights when
meeting another vehicle.
• Drive at speeds that allow you to maintain control at
all times.
• Do not apply the differential lock while traveling at
road speeds. The tractor may run out of control.
• 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.
• Keep the ROPS in the “UP” position and wear the
seat belt when driving the tractor on the road.
Otherwise, you will not be protected in the event of
a tractor roll-over.
• Do not operate an implement while the tractor is on
the road. Lock the 3-point hitch in the raised
position.
• When towing other equipment, use a safety chain
and place an SMV emblem on the equipment as
well.
(1) Safety chain
• Set the 3-point hitch-lowering speed knob in the
“LOCK” position to hold the implement in the raised
position.

(C) Lock
PRECAUTIONS FOR PARKING
THE TRACTOR
• 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 starter 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 [HST type].
• Make sure that the tractor has come to a complete
stop before dismounting from it.
• Avoid parking on steep slopes. If it is at all possible,
park on a firm and level surface. If it is not at all
possible to park on a firm and level surface, 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.
SAFE OPERATION
MX5400,MX6000

PRECAUTIONS FOR
OPERATING THE PTO
• Wait until all moving components have completely
stopped before getting off the tractor, connecting,
disconnecting, adjusting, cleaning, or servicing any
PTO driven equipment.
• 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
• Before installing or using PTO-driven-equipment,
read the manufacturer's manual and review the
safety labels attached to the equipment.
• 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.
PRECAUTIONS FOR USING 3-
POINT HITCH
• Use the 3-point hitch only with equipment designed
for the appropriate category of 3-point hitch usage.
• When using a 3-point-hitch-mounted-implement, be
sure to install the proper counterbalance-weight on
the front of the tractor.
• To avoid injury from separation, do not extend lift
rod beyond the groove on the threaded rod.
(1) Groove
PRECAUTIONS FOR
SERVICING THE TRACTOR
Before servicing the tractor, follow the following
procedure.
1. park the tractor on a firm, flat, and level surface.
2. Set the parking brake.
3. Lower all implements to the ground.
4. Place the gear-shift-lever in the neutral position.
5. Stop the engine.
6. Remove the starter key.
• Allow the tractor time to cool off before working on
or near the engine, muffler, radiator, and so on.
• Do not remove the radiator cap while coolant is hot.
When coolant is cool, slowly rotate the radiator cap
to the first stop and allow sufficient time for excess
pressure to escape before removing the radiator
cap completely. If the tractor is equipped with a
coolant-recovery-tank, add coolant or water to the
coolant-recovery-tank. Do not add coolant to the
radiator.
(See Checking the coolant level on page 126)
• Always stop the engine before refueling. Avoid
spills and overfilling.
• Do not smoke when working around the battery or
when the tractor is refueling. Keep all sparks and
flames away from the battery and fuel tank. The
battery presents an explosive hazard, because it
gives off hydrogen and oxygen especially when you
are recharging it.
• Before jump starting a dead battery, read and follow
all of the instructions.
(See JUMP STARTING THE ENGINE on page 64)
• Keep first-aid-kit and fire extinguisher handy at all
times.
• Disconnect the ground cable of battery before
working on or near electric components.
• 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
SAFE OPERATION
12
MX5400,MX6000

water as required so that the fluid level is between
the upper and lower levels.
• To avoid sparks from an accidental short circuit,
always disconnect the ground cable (-) of battery
first and reconnect it last.
(1) Battery
• Do not mount a tire on a rim. Only a qualified
person should mount a tire on a rim with the proper
equipment.
• Always maintain the correct tire pressure. Do not
inflate the tires above the recommended pressure
shown in Inflation pressure of tires on page 97.
• Securely support the tractor when either changing
wheels or adjusting the width of wheel tread.
• Make sure that the wheel bolts have been tightened
to the specified torque.
(See WHEEL ADJUSTMENT on page 97)
• 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 the tractor or any machine elements for
servicing or adjustment, securely support them with
stands or suitable blocking beforehand.
• Escaping hydraulic fluid under pressure obtains
sufficient force to penetrate skin, so escaping
hydraulic fluid under pressure can cause serious
personal injury. Before disconnecting the 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.
• Hydraulic fluid escaping from pinholes may be
invisible. Do not use hands to search for suspected
leaks. Use a piece of cardboard or wood to search
for suspected leaks. You should use safety goggles
or other eye protection. If injured by escaping fluid,
see a medical doctor at once. Hydraulic fluid will
produce gangrene or severe allergic reaction.
(1) Cardboard
(2) Hydraulic line
(3) Magnifying glass
• 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.
• 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.
• During the diesel-particulate-filter (hereinafter called
DPF) regenerating operations, the exhaust gases,
and the exhaust filter components reach
temperatures hot enough to burn people, or ignite
or melt common materials.
• Keep the tractor away from people, animals, or
structures which may be susceptible to harm or
damage from hot exhaust gases.
SAFE OPERATION
MX5400,MX6000
13

• To prevent fires, keep the DPF muffler and its
surroundings clear of anything flammable and keep
clean at all times.
• To avoid fire hazard:
After use and pressure-washing, make sure there is
nothing flammable near the exhaust pipe. Grass or
twigs under the hood may cause fire.
• During regeneration, white exhaust gas may be
visible. Do not allow regeneration in a non-
ventilated space.
• During regeneration, do not leave the tractor.
• The improper disposal or burning of waste causes
environmental pollution and can be punishable by
your local laws and regulations.
– When draining fluids from the tractor, place a
container underneath the drain port.
– Do not pour waste onto the ground, down a
drain, or into any water source (such as rivers,
streams, lakes, marshes, seas, and oceans).
– Waste products such as used oil, fuel, coolant,
hydraulic fluid, urea aqueous solution (DEF/
AdBlue®), refrigerant, solvent, filters, rubber,
batteries, and harmful substances, can harm
the environment, people, pets, and wildlife.
Please dispose properly.
See your local recycling center or KUBOTA
Dealer to learn how to recycle or get rid of
waste products.
