SAFE OPERATION
-1SAFE OPERATION
Careful operation is your best insurance against an accident.
Read and understand this manual carefully before operating the tractor.
All operators, no matter how much experience they may have, should read this and other related manuals before operating the tractor or any implement attached to it. It is the owner's obligation to instruct all operators in safe operation.
1. BEFORE OPERATING THE TRACTOR
1. Know your equipment and its limitations. Read this entire manual before attempting to start and operate the tractor.
2. Pay special attention to the danger, warning and caution labels on the tractor.
3. Do not operate the tractor or any implement attached to it while under the influence of alcohol, medication, controlled substances or while fatigued.
4. Before allowing other people to use your tractor, explain how to operate and have them read this manual before operation.
5. Never wear loose, torn, or bulky clothing around tractor. It may catch on moving parts or controls, leading to the risk of an accident. Use additional safety items, e.g. hard hat, safety boots or shoes, eye and hearing protection, gloves, etc., as appropriate or required.
6. Do not allow passengers to ride on any part of the tractor at anytime. The operator must remain in the tractor seat during operation.
7. Check brakes, clutch, linkage pins and other mechanical parts for improper adjustment and wear. Replace worn or damaged parts promptly. Check the tightness of all nuts and bolts regularly. (For further details, see "MAINTENANCE" section.)
8. Keep your tractor clean. Dirt, grease, and trash build up may contribute to fires and lead to personal injury.
9. Use only implements meeting the specifications listed under "IMPLEMENT LIMITATIONS" in this manual or implements approved by KUBOTA.
10.Use proper weights on the front or rear of the tractor to reduce the risk of upsets. When using the front loader, put an implement or ballast on the 3-point hitch to improve stability. Follow the safe operating procedures specified in the implement or attachment manual.
11. The narrower the tread, the greater the risk of a tractor upset. For maximum stability, adjust the wheels to the widest practical tread width for your application. (See "TIRES, WHEELS AND BALLAST" section.)
(1) Rear wheels (A) Tread Width
12.Do not modify the tractor. Unauthorized modification may affect the function of the tractor, which may result in personal injury.
C CAB, ROPS
1. KUBOTA recommends the use of a CAB or Roll Over Protective Structures (ROPS) and seat belt in almost all applications. This combination will reduce the risk of serious injury or death, should the tractor be upset. Check for overhead clearance which may interfere with a CAB or ROPS.
2. Set parking brake and stop engine. Remove any obstruction that may prevent raising or folding of the ROPS. Do not allow any bystanders. Always perform function from a stable position at the rear of the tractor. Hold the top of the ROPS securely when raising or folding. Make sure all pins are installed and locked.
3. If the CAB or ROPS is loosened or removed for any reason, make sure that all parts are reinstalled correctly before operating the tractor.
4. Never modify or repair any structural member of a CAB or ROPS because welding, bending, drilling, grinding, or cutting may weaken the structure.
5. A damaged CAB or ROPS structure must be replaced, not repaired or revised.
6. If any structural member of the CAB or ROPS is damaged, replace the entire structure at your local KUBOTA Dealer.
SAFE OPERATION-2
7. If the tractor is equipped with a foldable ROPS it may be temporarily folded down only when absolutely necessary for areas with height constraints. (There is no operator protection provided by the ROPS in the folded position. For operator safety the ROPS should be placed in the upright and locked position and the seat belt fastened for all other operations.)
8. Always use the seat belt if the tractor has a CAB or ROPS. Do not use the seat belt if a foldable ROPS is down or there is no ROPS. Check the seat belt regularly and replace if frayed or damaged.
3. Do not start engine by shorting across starter terminals or bypassing the safety start switch. Machine may start in gear and move if normal starting circuitry is bypassed.
4. Do not operate or idle engine in a non-ventilated area. Carbon monoxide gas is colorless, odorless, and deadly.
5. Check before each use that operator presence controls are functioning correctly. Test safety systems. (See "Checking Engine Start System" in "EVERY 50 HOURS" in "PERIODIC SERVICE" section.) Do not operate unless they are functioning correctly.
C Working
1. Pull only from the drawbar. Never hitch to axle housing or any other point except drawbar; such arrangements will increase the risk of serious personal injury or death due to a tractor upset.
(1) ROPS (2) Seat belt
2. OPERATING THE TRACTOR
Operator safety is a priority. Safe operation, specifically with respect to overturning hazards, entails understanding the equipment and environmental conditions at the time of use. Some prohibited uses which can affect overturning hazards include traveling and turning with implements and loads carried too high etc. This manual sets forth some of the obvious risks, but the list is not, and cannot be, exhaustive. It is the operator's responsibility to be alert for any equipment or environmental condition that could compromise safe operation.
C Starting
1. Always sit in the operator's seat when starting engine or operating levers or controls. Adjust seat per instructions in the operating the tractor section. Never start engine while standing on the ground.
2. Before starting the engine, make sure that all levers (including auxiliary control levers) are in their neutral positions, that the parking brake is engaged, and that both the clutch and the Power Take-Off (PTO) are disengaged or "OFF". Fasten the seat belt if the tractor has a CAB or a foldable ROPS in the upright and locked position.
(1) Drawbar
2. For trailing PTO-driven implements, set the drawbar to the towing position.
3. Attach pulled or towed loads to the drawbar only.
4. Keep all shields and guards in place. Replace any that are missing or damaged.
5. Avoid sudden starts. To avoid upsets, slow down when turning, on uneven ground, and before stopping.
6. The tractor cannot turn with the differential locked and attempting to do so could be dangerous.
7. Do not operate near ditches, holes, embankments, or other ground surface features which may collapse under the tractor's weight. The risk of tractor upset is even higher when the ground is loose or wet. Tall grass can hide obstacles, walk the area first to be sure.
8. Watch where you are going at all times. Watch for and avoid obstacles. Be alert at row ends, near trees, and other obstructions.
9. When working in groups, always let the others know what you are going to do before you do it.
10.Never try to get on or off a moving tractor.
11.Always sit in the operator's seat when operating levers or controls.
12.Do not stand between tractor and implement or trailed vehicle unless parking brake is applied.
-3SAFE 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.
C Operating on slopes
Slopes are a major factor related to loss-of-control and tip­over accidents, which can result in severe injury or death. All slopes require extra caution.
1. To avoid upsets, always back up steep slopes. If you cannot back up the slope or if you feel uneasy on it, do not operate on it. Stay off slopes too steep for safe operation.
2. Driving forward out of a ditch, mired condition or up a steep slope increases the risk of a tractor to be upset backward. Always back out of these situations. Extra caution is required with 4-wheel drive models because their increased traction can give the operator false confidence in the tractor's ability to climb slopes.
3. Keep all movement on slopes slow and gradual. Do not make sudden changes in speed, direction or apply brake and make sudden motions of the steering wheel.
4. Avoid disengaging the clutch or changing gears speed when climbing or going down a slope. If on a slope disengaging the clutch or changing gears to neutral could cause loss of control.
5. Special attention should be made to the weight and location of implements and loads as such will affect the stability of the tractor.
6. To improve stability on slope, set widest wheel tread as shown in "TIRES, WHEELS AND BALLAST" section. Follow recommendations for proper ballasting.
[Manual Transmission Type]
[HST Type]
(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 2 and 4-wheel drive. Be aware of the difference and use carefully.
3. Always slow the tractor down before turning. Turning at high speed may tip the tractor over.
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.
SAFE OPERATION-4
4. Make sure that the Slow Moving Vehicle (SMV) sign is clean and visible. Use hazard lights and turn signals as required.
(1) SMV emblem (2) Bracket
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.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.
11.Do not operate an implement while the tractor is on the road. Lock the 3-point hitch in the raised position.
12.When towing other equipment, use a safety chain and place an SMV emblem on it as well.
13.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"

4. OPERATING THE PTO
1. Wait until all moving components have completely stopped before getting off the tractor, connecting, disconnecting, adjusting, cleaning, or servicing any PTO driven equipment.
2. Keep the PTO shaft cover in place at all times. Replace the PTO shaft cap when the shaft is not in use.
(1) PTO Shaft cover (2) PTO Shaft cap
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"
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.
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.
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.
SAFE OPERATION-6
9. To avoid sparks from an accidental short circuit, always disconnect the battery's ground cable (-) first and reconnect it last.
(1) Battery
10.Do not attempt to mount a tire on a rim. This should be done by a qualified person with the proper equipment.
11.Always maintain the correct tire pressure. Do not inflate tires above the recommended pressure shown in the operator's manual.
15.Escaping hydraulic fluid under pressure has sufficient force to penetrate skin, causing serious personal injury. Before disconnecting hydraulic lines, be sure to release all residual pressure. Before applying pressure to the hydraulic system, make sure that all connections are tight and that all lines, pipes, and hoses are free of damage.
16.Fluid escaping from pinholes may be invisible. Do not use hands to search for suspected leaks; use a piece of cardboard or wood. Use of safety goggles or other eye protection is also highly recommended. If injured by escaping fluid, see a medical doctor at once. This fluid will produce gangrene or severe allergic reaction.
12.Securely support the tractor when either changing wheels or adjusting the wheel tread width.
13.Make sure that wheel bolts have been tightened to the specified torque.
14.Do not work under any hydraulically supported devices. They can settle, suddenly leak down, or be accidentally lowered. If it is necessary to work under tractor or any machine elements for servicing or adjustment, securely support them with stands or suitable blocking beforehand.
(1) Cardboard (2) Hydraulic line (3) Magnifying glass
17.Do not open high-pressure fuel system. High-pressure fluid remaining in fuel lines can cause serious injury. Do not disconnect nor attempt to repair fuel lines, sensors, or any other components between the high-pressure fuel pump and injectors on engines with high pressure common rail fuel system.
18.To avoid hazardous high voltage, turn the key switch to the OFF position if it is necessary to check to repair the computer, harness or connectors.
19.During Diesel Particulate Filter (hereinafter called DPF) regenerating operations, exhaust gases and exhaust filter components reach temperatures hot enough to burn people, or ignite or melt common materials.
20.Keep the tractor away from people, animals or structures which may be susceptible to harm or damage from hot exhaust gases.
21.To prevent fires, keep the DPF muffler and its surroundings clear of anything flammable and keep clean at all times.
22.During regeneration, white exhaust gas may be visible. Do not allow regeneration in a non-ventilated space.
23.During regeneration, do not leave the tractor.

OPERATING THE ENGINE
EXHAUST AFTERTREATMENT DEVICES
To avoid personal injury: A Read "Safe Operation" in the front of this
manual.
A Read the danger, warning and caution labels
located on the tractor.
A To avoid the danger of exhaust fume
poisoning, do not operate the engine in a closed building without proper ventilation.
A Never start engine while standing on ground.
Start engine only from operator's seat.
A Make it a rule to set all shift levers to the
"NEUTRAL" positions and to place PTO lever in "OFF" position before starting the engine.
A Do not use starting fluid or ether. A To protect the battery and the starter, make sure that
the starter is not continuously turned for more than 10 seconds.
BDiesel Particulate Filter (DPF) Muffler
This tractor is equipped with an engine with a DPF (Diesel Particulate Filter) muffler which serves to reduce hydrocarbons, carbon monoxide and other toxic gases, all of which are contained in diesel engine emissions, to harmless carbon dioxide and water. The DPF also traps PM (particulate matter). Please handle exhaust aftertreatment devices correctly and in an environmentally responsible manner.
13OPERATING THE ENGINE
To avoid personal injury: A During Diesel Particulate Filter (DPF)
regenerating operations, exhaust gases and exhaust filter components reach temperatures hot enough to burn people, or ignite or melt common materials.
A Keep tractor away from people, animals or
structures which may be susceptible to harm or damage from hot exhaust gases.
A During regeneration, white exhaust gases may
be visible. Do not allow regeneration in a non ventilated garage or confined area.
A During regeneration, do not leave the tractor.
(1) Diesel Particulate Filter (DPF)
OPERATING THE ENGINE14
BHandling Points
When a specific amount of PM (particulate matter) has accumulated in the DPF muffler, it is necessary to refresh the DPF muffler by burning the PM inside it. This burning off work is called "Regeneration". To extend operating time to reach this regeneration, and to avoid DPF muffler trouble, make sure to observe the following handling matters.
C Fuel
Be sure to use Ultra Low Sulfur Fuel (S15).
A Use of diesel fuel other than Ultra Low Sulfur Fuel
may adversely affect the engine and DPF performance. Use of fuels other than Ultra Low Sulfur Fuel (S15) may not meet regulations for your region.
C Engine oil
Use DPF-compatible oil (CJ-4) for the engine.
A If any engine oil other than CJ-4 is used, the DPF
may become clogged earlier than expected and the fuel economy may drop.
C Prohibition of unnecessary idling operation
Generally, the lower the engine speed, the lower the exhaust gas temperature is, so the PM contained in exhaust gas will not be burnt, and begins to accumulate. Therefore, don't idle unnecessarily.
C Regeneration
When there is "Regeneration" instruction sign by lamp or buzzer, immediately perform the required procedure for regeneration.
A Interrupting the regeneration cycle or continued
operation by ignoring the warning signs may cause DPF and engine damage.
BDPF Regeneration Process
DPF regeneration process can be performed by choosing from "Auto Regeneration" or "Regeneration inhibit" mode according to your job conditions. For jobs not affected by hot gases emitted during regeneration, the "Auto Regeneration" is advisable.
C Auto Regeneration Mode;
When starting the engine (switch operation is unnecessary), the "Auto Regeneration" mode is automatically activated. With the auto regeneration mode on, when a specific amount of PM has accumulated, and the regeneration conditions are satisfied (See the "Tips on Diesel Particulate Filter [DPF] Regeneration"), the DPF will be automatically regenerated whether the tractor is in motion or parked. By this way, work efficiency is improved. For details of auto regeneration, refer to "Operating Procedure for Auto Regeneration Mode" section.
C Regeneration Inhibit Mode;
After starting the engine, if the "DPF INHIBIT switch" is pressed to turn on the switch lamp, the "Regeneration inhibit" mode will be activated. With "Regeneration Inhibit" mode on, the PM which has accumulated inside the DPF will not be burnt, unless the operator performs the regeneration work manually. The "Regeneration Inhibit" mode is effective for work in poorly ventilated work spaces. For details of regeneration prohibition, refer to "Operating Procedure for Regeneration Inhibit Mode" section.
A If stop the engine once, the "Auto Regeneration" mode
will be activated.

BRegeneration Operating Procedure
Start the engine.
1.
(Make sure that the DPF INHIBIT switch lamp is "OFF".)
Switch lamp OFF: Auto Regeneration Mode activated. Switch lamp ON: Regeneration Inhibit Mode activated.
A When the engine is started, the "Auto Regeneration" mode is automatically activated. A "Regeneration Inhibit" mode is activated, when the DPF INHIBIT switch is pushed after the engine is started.
When the regeneration indicator starts flashing:
2.
A specific amount of PM has built up in the DPF. Continue to operate the tractor, and the regeneration process will begin automatically, make sure the working place is in a safe area as DPF and exhaust temperature will rise.
When the engine rpm increase indicator starts flashing:
3.
Keep on working and increase the engine rpm until the indicator turns "OFF".
A Even if the Auto Regeneration Mode is selected, DPF regeneration may not begin because system requirements have
not been satisfied.
A The engine rpm increase indicator is used as a guide to satisfy the regeneration conditions. If the engine load is too
heavy, the engine rpm increase indicator may continue to flash, even though regeneration system conditions are satisfied and regeneration may begin automatically. (See the "Tips on Diesel Particulate Filter [DPF] Regeneration")
16 OPERATING THE ENGINE
BPM Warning Level and Required Procedures
During Auto Regeneration Mode when the PM level has built up in the DPF, the regeneration cycle will begin automatically. If the regeneration cycle is interrupted or the regeneration conditions are not satisfied, the buzzer starts sounding and the indicator display changes in response to the PM level in order to prompt the operator to perform the required procedure listed below.
A Once the regeneration level has been reached, immediately perform the required procedure for regeneration.
Interrupting the regeneration cycle or continued operation by ignoring the warning signs may cause DPF and engine damage.

OPERATING THE ENGINE20
BTips on Diesel Particulate Filter (DPF)
Regeneration
A Operation
The higher in speed or load the engine operates, the higher the exhaust temperature rises. As a result, particulate matter (PM) inside the DPF is consumed, therefore the regeneration process is required less frequently over time. The lower in speed or load the engine operates, the lower the exhaust temperature. Accordingly, less particulate matter (PM) inside the DPF is consumed, therefore more accumulation of PM will occur, which requires frequent regeneration, therefore avoid prolonged idling if possible.
A Necessary conditions for "Regeneration"
When conditions below are all satisfied, regeneration will start. However, if even one condition is deviated during the process, the regeneration will be interrupted. (1) The engine coolant temperature. (2) The DPF temperature. (3) The engine speed is 1200 rpm or higher.
A Usually it takes 15-20 minutes to complete the
regeneration cycle. Actual regeneration time may depend on ambient temperature, exhaust temperature and engine speed.
A It is recommended to do the regenerating while the
engine is warm.
STARTING THE ENGINE
1. Make sure the parking brake is set.
1. To set the parking brake; (1) Interlock the brake pedals. (2) Depress the brake pedals. (3) Latch the brake pedals with the parking brake
lever.
2. To release the parking brake, depress the brake pedals again.
(1) Parking brake lever (A) Interlock the brake pedals
(B) "DEPRESS" (C) "PUSH"
A Do not unnecessarily start and interrupt the
regeneration process. Otherwise, a small amount of fuel becomes mixed with the engine oil, which degrades the oil quality.
A While the DPF is being regenerated, the engine air
flow rate is automatically limited to keep up the exhaust temperature. Because of this the engine may sound differently, this is normal for this engine.
A Just after the regeneration has ended, the DPF muffler
remains hot. It is advisable to keep the engine running for about 5 minutes to allow cooling of the exhaust components.
A To prevent damage to the parking brake lever, make
sure that brake pedals are fully depressed before pushing the parking brake lever.
A The Parking brake indicator comes on while parking
brake is applied and goes off when it is released.

up.
A Be sure to set all shift levers to the "NEUTRAL"
positions and to place PTO 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.
10. Turn the key to the start position and the engine should start.
(If the engine fails to start after 10 seconds, turn off the key for 30 seconds. Then repeat steps (9) and (10). To protect the battery and the starter, make sure that the starter is not continuously turned for more than 10 seconds.)
BBlock Heater (if equipped)
A block heater is available as an option from your dealer. It will assist you in starting your tractor when the ambient temperature is below -20 (-4 ).
BWarm-Up Transmission Oil in the 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 temperature Warm-up time requirement
Above 0 (32 ) At least 10 minutes
0 to -10 (32 to 14 ) 10 to 20 minutes
-10 to -20 (14 to -4 ) 20 to 30 minutes
Below -20 (-4 ) More than 30 minutes
A Do not operate the tractor under full load condition until
it is sufficiently warmed up.
JUMP STARTING
To avoid personal injury: 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 other end of negative (-) jumper
cable to negative (-) terminal of tractor battery.
When jump starting engine, follow the instructions below to safely start the engine.
1. Bring 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.

26 OPERATING THE TRACTOR
OPERATING THE TRACTOR
OPERATING NEW TRACTOR
How a new tractor is handled and maintained determines the life of the tractor. A new tractor just off the factory production line has been, of course, tested, but the various parts are not accustomed to each other, so care should be taken to operate the tractor for the first 50 hours at a slower speed and avoid excessive work or operation until the various parts become "broken-in". The manner in which the tractor is handled during the "breaking-in" period greatly affects the life of your tractor. Therefore, to obtain the maximum performance and the longest life of the tractor, it is very important to properly break-in your tractor. In handling a new tractor, the following precautions should be observed.
BDo not Operate the Tractor at Full Speed
for the First 50 Hours
A Do not start quickly nor apply the brakes suddenly. A In winter, operate the tractor after fully warming up the
engine.
A Do not run the engine at speeds faster than
necessary.
A On rough roads, slow down to suitable speeds.
Do not operate the tractor at fast speed.
The above precautions are not limited only to new tractors, but to all tractors. But it should be especially observed in the case of new tractors.
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.)
BOARDING AND LEAVING THE TRACTOR
1. Never try to get on or off a moving tractor or jump off the tractor to exit.
2. Face the tractor when getting into or out of the tractor. Do not use the controls as hand holds to prevent inadvertent machine movements.
3. Always keep steps and floor clean to avoid slippery conditions.

A If the differential lock cannot be released, 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.
Be sure SMV emblem and warning lamps are clean and visible. If towed or rear-mounted equipment obstructs these safety devices, install SMV emblem and warning lamps on equipment. Consult your local KUBOTA Dealer for further details.
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 the
clutch or shift levers to neutral. Doing so could cause loss of control.
A Do not drive the tractor close to the edges of
ditches or banks which may collapse under the weight of the tractor. Especially when the ground is loose or wet.
1. Be sure wheel tread is adjusted to provide maximum stability. (See "WHEEL ADJUSTMENT" in "TIRES, WHEELS AND BALLAST" section.)
2. Slow down for slopes, rough ground, 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.
(1) SMV emblem (2) Bracket
BTransport the Tractor Safely
1. The tractor, if damaged, must be carried on a truck. Secure the tractor tightly with ropes.
2. Follow the instruction below when towing the tractor: Otherwise, the tractor’s powertrain may get damaged.
A Set the all shift levers to "NEUTRAL" position. A If possible, start engine and select 2WD, if creep
speed is fitted ensure that it is disengaged.
A Tow the tractor using its front hitch or drawbar. A Never tow faster than "10 km/h (6.2 mph)".
BDirections for Use of Power Steering
1. Power steering is activated only while the engine is running. Slow engine speeds make the steering a little heavier. While the engine is stopped, the tractor functions in the same manner as tractors without power steering.
2. When the steering wheel is turned all the way to the stop, the relief valve is activated. Do not hold the steering wheel in this position for a long period of time.
3. Avoid turning the steering wheel while the tractor is stopped, or tires may wear out sooner.
4. The power steering mechanism makes the steering easier. Be careful when driving on a road at high speeds.
