SAFE OPERATION -1

SAFE OPERATION

Careful operation is your best insurance against an accident.

Read and understand this manual carefully before operating the tractor.

All operators, no matter how much experience they may have, should read this and other related manuals before operating the tractor or any implement attached to it. It is the owner's obligation to instruct all operators in safe operation.

1.BEFORE OPERATING THE TRACTOR

1.Know your equipment and its limitations. Read this entire manual before attempting to start and operate the tractor.

2.Pay special attention to the danger, warning and caution labels on the tractor.

3.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.

-2 SAFE OPERATION

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.

(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.

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

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.

SAFE OPERATION -3

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.

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.

[Manual Transmission Type]

[HST Type]

(1) Brake Pedal (LH)

(A) Whenever travelling on the road

(2)Brake Pedal (RH)

(3)Brake Pedal Lock

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.

-4 SAFE OPERATION

4.Make sure that the Slow Moving Vehicle (SMV) sign is clean and visible. Use hazard lights and turn signals as required.

13.Set the implement lowering speed knob in the "LOCK" position to hold the implement in the raised position.

(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.

(1) 3-point hitch lowering speed knob	(A) "FAST"
	(B) "SLOW"
	(C) "LOCK"

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).

2.Make sure that the tractor has come to a complete stop before dismounting.

3.Avoid parking on steep slopes, if at all possible park on a firm and level surface; if not, park across a slope with chock the wheels.

Failure to comply with this warning may allow the tractor to move and could cause injury or death.

(1) Safety chain

SAFE OPERATION -5

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	(A) "NORMAL POSITION"
(2)	PTO Shaft cap	(B) "RAISED POSITION"

3.Before installing or using PTO driven equipment, read the manufacturer's manual and review the safety labels attached to the equipment.

4.When operating stationary PTO driven equipment, always apply the tractor parking brake and place chocks behind and in front of the rear wheels. Stay clear of all rotating parts. Never step over rotating parts.

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.

-6 SAFE OPERATION

9.To avoid sparks from an accidental short circuit, always disconnect the battery's ground cable (-) first and reconnect it last.

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.

(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.

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.

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.

(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.

SAFE OPERATION -7

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.

-10 SAFE OPERATION

8.CARE OF DANGER, WARNING AND CAUTION LABELS

1.Keep danger, warning and caution labels clean and free from obstructing material.

2.Clean danger, warning and caution labels with soap and water, dry with a soft cloth.

3.Replace damaged or missing danger, warning and caution labels with new labels from your local KUBOTA Dealer.

4.If a component with danger, warning and caution 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 danger, warning and caution labels by applying on a clean dry surface and pressing any bubbles to outside edge.
