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 pictorial safety labels on the tractor.
3. Do not operate tractor or any implement attached to it while under the influence of alcohol, medication, controlled substances or while fatigued.
4. Carefully check the vicinity before operating tractor or any implement attached to it. Do not allow any bystanders around or near tractor during operation.
5. Before allowing other people to use your tractor, explain how to operate and have them read this manual before operation.
6. 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.
7. Do not allow passengers to ride on any part of the tractor at anytime. The operator must remain in the tractor seat during operation.
8. 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.)
9. Keep your tractor clean. Dirt, grease, and trash build up may contribute to fires and lead to personal injury.
10.Use only implements meeting the specifications listed under "IMPLEMENT LIMITATIONS" in this manual or implements approved by KUBOTA.
11.Use proper weights on the front or rear of the tractor to reduce the risk of upsets. Follow the safe operating procedures specified in the implement or attachment manual.
12. 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
13.Do not modify the tractor. Unauthorized modification may affect the function of the tractor, which may result in personal injury.
C CAB, ROPS
1. KUBOTA recommends the use of a CAB or Roll Over Protective Structures (ROPS) and seat belt in almost all applications. This combination will reduce the risk of serious injury or death, should the tractor be upset. Check for overhead clearance which may interfere with a CAB or ROPS.
2. If the CAB or ROPS is loosened or removed for any reason, make sure that all parts are reinstalled correctly before operating the tractor.
3. Never modify or repair any structural member of a CAB or ROPS because welding, bending, drilling, grinding, or cutting may weaken the structure.
4. A damaged CAB or ROPS structure must be replaced, not repaired or revised.
5. If any structural member of the CAB or ROPS is damaged, replace the entire structure at your local KUBOTA Dealer.
6. Always use the seat belt if the tractor has a CAB or ROPS. Do not use the seat belt if a foldable ROPS is down or there is no ROPS. Check the seat belt regularly and replace if frayed or damaged.
SAFE OPERATION-2
(1) CAB (2) Seat belt
C Working
1. Pull only from the hitch devices. Never hitch to axle housing or any other point except drawbar; such arrangements will increase the risk of serious personal injury or death due to a tractor upset.
2. OPERATING THE TRACTOR
Operator safety is a priority. Safe operation, specifically with respect to overturning hazards, entails understanding the equipment and environmental conditions at the time of use. Some prohibited uses which can affect overturning hazards include traveling and turning with implements and loads carried too high etc. This manual sets forth some of the obvious risks, but the list is not, and cannot be, exhaustive. It is the operator's responsibility to be alert for any equipment or environmental condition that could compromise safe operation.
C Starting
1. Always sit in the operator's seat when starting engine or operating levers or controls. Adjust seat per instructions in the operating the tractor section. Never start engine while standing on the ground.
2. Before starting the engine, make sure that all levers (including auxiliary control levers) are in their neutral positions, that the parking brake is engaged, and that both the clutch and the Power Take-Off (PTO) are disengaged or "OFF". Fasten the seat belt if the tractor has a CAB, a fixed ROPS or a foldable ROPS in the upright and locked position.
3. Do not start engine by shorting across starter terminals or bypassing the safety start switch. Machine may start in gear and move if normal starting circuitry is bypassed.
4. Do not operate or idle engine in a non-ventilated area. Carbon monoxide gas is colorless, odorless, and deadly.
5. Check before each use that operator presence controls are functioning correctly. Test safety systems. (See "Checking Engine Start System" in "EVERY 50 HOURS" in "PERIODIC SERVICE" section.) Do not operate unless they are functioning correctly.
(1) Drawbar
(1) High-hitch
2. For trailing PTO-driven implements, set the hitch devices to the towing position.
3. Attach pulled or towed loads to the hitch devices 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.
-3SAFE OPERATION
10.Never try to get on or off a moving tractor.
11.Always sit in the operator's seat when operating levers or controls.
12.Do not use "Bi-speed Turn" at high speed.
13."Bi-Speed Turn" enables short and fast turns, therefore, become familiar with its performance before operating in close or confined areas.
14.Do not stand between tractor and implement or trailed vehicle unless parking brake is applied.
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.
7. To avoid free wheeling:
A Do not shift the shuttle lever while on a slope. A Stop completely by using the brake and by
depressing the clutch pedal, then shift the shuttle lever.
A Start off after selecting shuttle direction, by
releasing the clutch pedal.
C Driving the tractor on the road
1. Lock the two brake pedals together to help assure straight-line stops. Uneven braking at road speeds could cause the tractor to tip over.
(1) Brake Pedal (LH) (2) Brake Pedal (RH) (3) Brake Pedal Lock
(A) Whenever travelling on the road
C Operating on slopes
Slopes are a major factor related to loss-of-control and tip­over accidents, which can result in severe injury or death. All slopes require extra caution.
1. To avoid upsets, always back up steep slopes. If you cannot back up the slope or if you feel uneasy on it, do not operate on it. Stay off slopes too steep for safe operation.
2. Driving forward out of a ditch, mired condition or up a steep slope increases the risk of a tractor to be upset backward. Always back out of these situations. Extra caution is required with four-wheel drive models because their increased traction can give the operator false confidence in the tractor's ability to climb slopes.
3. Keep all movement on slopes slow and gradual. Do not make sudden changes in speed, direction or apply brake and make sudden motions of the steering wheel.
4. Avoid disengaging the clutch or changing gears speed when climbing or going down a slope. If on a slope disengaging the clutch or changing gears to neutral could cause loss of control.
5. Special attention should be made to the weight and location of implements and loads as such will affect the stability of the tractor.
6. To improve stability on slope, set widest wheel tread as shown in "TIRES, WHEELS AND BALLAST" section. Follow recommendations for proper ballasting.
2. Check the front wheel engagement. The braking characteristics are different between two and four wheel drive. Be aware of the difference and use carefully.
3. Always slow the tractor down before turning. Turning at high speed may tip the tractor over.
4. Observe all local traffic and safety regulations. Use the registration plate as required.
(1) Registration plate
5. Turn the headlights on. Dim them when meeting another vehicle.
6. Drive at speeds that allow you to maintain control at all times.
SAFE OPERATION-4
7. Do not apply the differential lock while traveling at road speeds. The tractor may run out of control.
8. 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.
9. Do not operate an implement while the tractor is on the road. Lock the 3-point hitch in the raised position.
10.Set the implement lowering speed lever in the "LOCK" position to hold the implement in the raised position.
(1) 3-point hitch lowering speed lever (A) "FAST"
(B) "SLOW" (C) "LOCK"
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.
3. PARKING THE TRACTOR
1. Disengage the PTO, lower all implements to the ground, place all control levers in their neutral positions, set the parking brake, stop the engine, remove the key from the ignition and lock the cab door (if equipped). Leaving transmission in gear with the engine stopped will not prevent tractor from rolling.
2. Make sure that the tractor has come to a complete stop before dismounting.
3. Avoid parking on steep slopes, if at all possible park on a firm and level surface; if not, park across a slope 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.
5. USING 3-POINT HITCH
1. Use the 3-point hitch only with equipment designed for 3-point hitch usage.
2. When using a 3-point hitch mounted implement, be sure to install the proper counterbalance weight on the front of the tractor.
3. To avoid injury from separation: Do not extend lift rod beyond the groove on the threaded rod.
(1) Groove
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.
9. To avoid sparks from an accidental short circuit, always disconnect the battery's ground cable (-) first and reconnect it last.
-5SAFE OPERATION
11.Always maintain the correct tire pressure. Do not inflate tires above the recommended pressure shown in the operator's manual.
12.Securely support the tractor when either changing wheels or adjusting the wheel tread width.
13.Make sure that wheel bolts have been tightened to the specified torque.
14.Disconnect the battery's ground cable and stop the engine to avoid the possibility of the machine runaway due to 4WD braking system during testing, service or repair with only rear wheels off the ground.
15.Do not work under any hydraulically supported devices. They can settle, suddenly leak down, or be accidentally lowered. If it is necessary to work under tractor or any machine elements for servicing or adjustment, securely support them with stands or suitable blocking beforehand.
16.Escaping hydraulic fluid under pressure has sufficient force to penetrate skin, causing serious personal injury. Before disconnecting hydraulic lines, be sure to release all residual pressure. Before applying pressure to the hydraulic system, make sure that all connections are tight and that all lines, pipes, and hoses are free of damage.
(1) Battery
10.Do not attempt to mount a tire on a rim. This should be done by a qualified person with the proper equipment.
SAFE OPERATION-6
17.Fluid escaping from pinholes may be invisible. Do not use hands to search for suspected leaks; use a piece of cardboard or wood. Use of safety goggles or other eye protection is also highly recommended. If injured by escaping fluid, see a medical doctor at once. This fluid will produce gangrene or severe allergic reaction.
(1) Cardboard (2) Hydraulic line (3) Magnifying glass
18.Waste products such as used oil, fuel, hydraulic fluid, and batteries, 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.
-7SAFE OPERATION
7. PICTORIAL SAFETY LABELS
The pictorial safety labels affixed are intended to alert persons to potential hazards. The hazard is identified by a pictorial in the safety alert triangle or by the safety alert symbol alone. An adjacent pictorial provides instructions and information on how to avoid the hazard.
SAFE OPERATION-8
-9SAFE OPERATION
SAFE OPERATION-10
8. CARE OF PICTORIAL SAFETY LABELS
1. Keep pictorial safety labels clean and free from obstructing material.
2. Clean pictorial safety labels with soap and water, dry with a soft cloth.
3. Replace damaged or missing pictorial safety labels with new labels from your local KUBOTA Dealer.
4. If a component with pictorial safety label(s) affixed is replaced with new part, make sure new label(s) is (are) attached in the same location(s) as the replaced component.
5. Mount new pictorial safety labels by applying on a clean dry surface and pressing any bubbles to outside edge.

WARMING UP
To avoid personal injury: A Be sure to set the parking brake during warm-
up.
A Be sure to set all shift levers to the "NEUTRAL"
positions and to place PTO switch in "OFF" position during warm-up.
For five minutes after engine start-up, allow engine to warm up without applying any load, this is to allow oil to reach every engine part. If load should be applied to the engine without this warm-up period, trouble such as seizure, breakage or premature wear may develop.
BWarm-up and Transmission Oil at Low
Temperature Range
Hydraulic oil serves as transmission fluid. In cold weather, the oil may be cold with increased viscosity. This can cause delayed oil circulation or abnormally low hydraulic pressure for some time after engine start-up. This in turn can result in trouble in the hydraulic system. To prevent the above, observe the following instructions: Warm up the engine at about 50 % of rated rpm according to the table below:
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.
3. Put on safety goggles and rubber gloves.
4. Ensure the vent caps are securely in place. (if equipped)
5. Cover vent holes with damp rags. Do not allow the rag to touch the battery terminals.
6. 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.
7. Clamp the other cable to the negative (black, (-) or neg.) terminal of the helper battery.
8. Clamp the other end to the engine block or frame of the disabled tractor as far from the dead battery as possible.
9. Start the helper vehicle and let its engine run for a few moments. Start the disabled tractor.
10.Disconnect the jumper cables in the exact reverse order of attachment. (Steps 8, 7 and 6).
11.Remove and discard the damp rags.

19OPERATING THE TRACTOR
OPERATING NEW TRACTOR
How a new tractor is handled and maintained determines the life of the tractor. A new tractor just off the factory production line has been, of course, tested, but the various parts are not accustomed to each other, so care should be taken to operate the tractor for the first 50 hours at a slower speed and avoid excessive work or operation until the various parts become "broken-in". The manner in which the tractor is handled during the "breaking-in" period greatly affects the life of your tractor. Therefore, to obtain the maximum performance and the longest life of the tractor, it is very important to properly break-in your tractor. In handling a new tractor, the following precautions should be observed.
BDo not Operate the Tractor at Full Speed
for the First 50 Hours.
A Do not start quickly nor apply the brakes suddenly. A In winter, operate the tractor after fully warming up the
engine.
A Do not run the engine at speeds faster than
necessary.
A On rough roads, slow down to suitable speeds. Do not
operate the tractor at fast speed. The above precautions are not limited only to new tractors, but to all tractors. But it should be especially
observed in the case of new tractors.
BOARDING AND LEAVING THE TRACTOR
1. Never try to get on or off a moving tractor or jump off the tractor to exit.
2. Face the tractor when getting into or out of the tractor. Do not use the controls as hand holds to prevent inadvertent machine movements.
3. Always keep steps and floor clean to avoid slippery conditions.
STARTING
1. Adjusting the Operator's Position.
A The seat and suspension should be adjusted to
ensure that the controls are comfortably at hand for the operator, ensuring that the operator maintains a good posture and minimizes risks from whole body vibration.
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.)

BBrake Pedals (Right and Left)
To avoid personal injury: A Be sure to interlock the right and left pedals.
Applying only one rear wheel brake at high speeds could cause the tractor to swerve or roll-over.
A Be sure brake pedals have equal adjustment
when using locked together. Incorrect or unequal brake pedal adjustment can cause the tractor to swerve or roll-over.
To avoid personal injury: A Be aware of the enhanced braking
characteristics of 4 wheel braking system. Appropriate care should be taken during hard braking and/or when pulling towed loads.
A Do not make sudden braking.
An accident may occur such as by heavy towed load shifting forward or loss of control.
A To avoid skidding and less of steering control
when driving on icy, wet, or loose surfaces, make sure the tractor is correctly ballasted, operated at reduced speed, operated with front wheel drive engaged (If equipped).
A The braking characteristics are different
between two and four wheel drive. Be aware of the difference and use carefully.
1. Before operating the tractor on the road, be sure to interlock the right and left pedals as illustrated below.
2. Use individual brakes to assist in making sharp turns at slow speeds (Field Operation Only). Disengage the brake pedal lock and depress only one brake pedal.

B4WD / Bi-speed Turn Switch
To avoid personal injury: A Do not engage the front wheel drive when
traveling at road speed.
A When driving on icy, wet, or loose surfaces,
make sure the tractor is correctly ballasted to avoid skidding and loss of steering control. Operate at reduced speed and engage front wheel drive.
A 4WD model tractor is equipped with 4 wheel
braking and appropriate care should be taken during hard braking.
A An accident may occur if the tractor is
suddenly braked, such as by heavy towed loads shifting forward or loss of control.
A The braking characteristics are different
between two and four wheel drive tractor models. Be aware of the difference and use carefully.
A Do not use "Bi-speed Turn" at high speed. A "Bi-speed Turn" enables short and fast turns,
therefore, become familiar with its performance before operating in close or confined areas.
A Do not use the Bi-speed turn when operating
the front end loader.
When this switch is pressed;
The front wheel drive (4WD) is engaged. The 4WD indicator comes on when the system is in 4WD mode.
Press the switch again;
The Bi-speed turn system activates. The indicator within the switch and 4WD indicator and Bi-speed turn indicator come on when the system is in Bi-speed turn mode.
To avoid personal injury: A When you leave the tractor, be sure to apply the
parking brake and stop the engine.
A IN APPLYING THE BRAKES:
A The torque of the wheel axle is extremely
high while creep speed is being used. Be sure to step down on the clutch pedal completely before applying the brakes, or they will not work
A When starting to operate the tractor, be sure
to release the parking brakes. Misuse of the brakes may cause damage to the transmission and is therefore not acceptable to KUBOTA for coverage under the warranty.
A Press the clutch pedal completely down and stop the
tractor's motion before shifting the range gear shift lever.
Press the switch one more time;
The drive system returns to 2WD mode. All the indicators go off when the system is in 2WD mode. (While the brake pedal is stepped on or the parking brake is applied, however, the 4WD braking system is working and the 4WD indicator stays on.)

on the brake pedals alternately.
35OPERATING THE TRACTOR
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.
Observe all local traffic and safety regulations. Use the registration plate.
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, and 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) Registration plate
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.

GROUND PTO OPERATION
(if equipped)
To avoid personal injury: A Do not shift the ground/engine PTO select lever
while in operation. If the select lever is returned to the neutral position, the power to the wheels of a power trailer or any similar implement is cut off, which is very dangerous.
A The ground PTO revolution is made in
proportion to the tractor speed. To avoid too high speeds of this shaft, make sure the ground/engine PTO select lever is at the neutral position when the tractor travels at high speed.
To avoid personal injury: A When working with a power trailer on a slope or
rugged road, follow the allowable load capacity specified in the Operator's Manual and avoid travelling at high speed for added safety.
A The ground PTO revolution is made in
proportion to the tractor speed. In backing the tractor, this shaft turns in the opposite direction.
BGround / Engine PTO Select Lever
This lever provides for the following two different PTO speeds.
1. Ground PTO:
The PTO shaft revolution in proportion to the tractor speed is achieved, which is suited for power trailers, planters and other tractor speed-interlocked implements. The PTO shaft turning direction is clockwise when viewed from the back of the tractor.
2. Engine PTO:
The PTO shaft rpm in proportion to the engine speed is achieved, which is suited for mowers, harvesters and other general implements. (For details, see "PTO OPERATION" in the previous page.)
C Operation
1. Step on the clutch pedal and the brake pedal at once to stop the tractor.
2. Set the PTO clutch control switch to the "OFF" position.
3. To select "Ground PTO", pull up the lever. In this case, the PTO clutch indicator on the meter panel lights up.
(1) Ground / Engine PTO select lever (A) "GROUND PTO"
(N) "NEUTRAL" (B) "ENGINE PTO"
A When you do not want a coupled implement to turn in
the opposite direction in backing the tractor, set the ground/engine PTO select lever to the neutral position in advance. (The PTO shaft does not stop even if the PTO clutch control switch is set to the "OFF" position.)
A When neither "Ground PTO" nor "Engine PTO" is
used, set the ground/engine PTO select lever to the neutral position. If a power trailer is used with "Engine PTO", the PTO clutch may get damaged.
A Stop the tractor first before using the ground/engine
PTO select lever. Do not shift this lever while the tractor is running.
A When an implement (example: power trailer) is heavy
in traction force, do not operate the tractor at creep speed (if equipped).
C Ground PTO revolutions (PTO shaft revolutions
per wheel turn)
The PTO shaft revolutions per wheel turn, with the PTO gear shift lever being selected, are as shown below.

A When a power trailer or other tractor speed-
interlocked implement is coupled, employ a specific model that suits the tractor speed. If an unmatched implement is connected, the tractor or the implement may get in trouble.
A Before starting the job, check the PTO gear shift lever
position too.
A 540E rpm or 1000 rpm use is recommended for the
ground PTO implement. For details on matching and other requirements, consult with your local KUBOTA Dealer.

BFloat Control
Place both the draft control lever and the position control lever in the float position to make the lower links move freely along with the ground conditions.
B3-point Hitch Lowering Speed
To avoid personal injury: A Fast lowering speed may cause damage or
injury. Lowering speed of implement should be adjusted to two or more seconds.
The lowering speed of the 3-point hitch can be controlled by adjusting the 3-point hitch lowering speed lever.
BRemote Control Valve
There are two types of remote valves available for these models. A Double acting valve with detents and self cancelling:
This valve may be placed in the detent mode. The lever will stay in this position until the pressure reaches a predetermined level or a cylinder reaches the end of its stroke. Then it will automatically return to neutral.
A Single/double acting valve:
This valve can be utilized as single or double acting valve by adjusting the auxiliary control valve selector knob located on the valve.
1) Turn the auxiliary control valve selector knob clockwise all the way to utilize as single acting valve.
2) Turn the auxiliary control valve selector knob anticlockwise all the way to utilize as double acting valve.

C Engine Oil:
A Oil used in the engine should have an American Petroleum Institute (API) service classification and Proper SAE
Engine Oil according to the ambient temperatures as shown above:
A With the emission control now in effect, the CF-4 and CG-4 lubricating oils have been developed for use of a low-
sulfur fuel on on-road vehicle engines. When an off-road vehicle engine runs on a high-sulfur fuel, it is advisable to employ the "CF or better" lubricating oil with a high Total Base Number (TBN of 10 minimum).
A Refer to the following table for the suitable API classification engine oil according to the engine type (with internal
EGR, external EGR or non-EGR) and the fuel (low-sulfur or high-sulfur fuel).
71MAINTENANCE
Fuel used
High Sulfur Fuel [ 0.05% (500 ppm)]
Low Sulfur Fuel [<0.05% (500 ppm)] or Ultra Low Sulfur Fuel [<0.0015% (15 ppm)]
EGR: Exhaust Gas Re-circulation
A The CJ-4 engine oil is intended for DPF (Diesel Particulate Filter) type engines, and cannot be used on this tractor.
C Fuel:
A Cetane number of 45 minimum. Cetane number greater than 50 is preferred, especially for temperatures below
-20 or elevations above 1500 m.
A If diesel fuel with sulfur content greater than 0.5% (5000 ppm) sulfur content is used, reduce the service interval for
engine oil and filter by 50%.
A NEVER use diesel fuel with sulfur content greater than 0.05% (500 ppm) for EXTERNAL EGR type engine. A DO NOT use diesel fuel with sulfur content greater than 1.0% (10000 ppm). A Diesel fuels specified to EN 590 or ASTM D975 are recommended. A No.2-D is a distillate fuel of lower volatility for engines in industrial and heavy mobile service. (SAE J313 JUN87)
C Transmission Oil:
The oil used to lubricate the transmission is also used as hydraulic fluid. To insure proper operation of the hydraulic system and to complete lubrication of the transmission, it is important that a multi-grade transmission fluid is used in this system. We recommend the use of KUBOTA UDT or SUPER UDT fluid for optimum protection and performance. (Consult your local KUBOTA Dealer for further detail.) Do not mix different brands together.
A Indicated capacities of water and oil are manufacturer's estimate.
