• Do not operate the tractor or any implement attached to it while under the influence of alcohol, medication, controlled substances or while fatigued.
• Before allowing other people to use your tractor, explain how to operate and have them read this manual before operation.
• 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, such as a 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 operation.
• 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. (See MAINTENANCE on page 91.)
• Keep your tractor clean. Dirt, grease, and trash build up may contribute to fires and lead to personal injury.
• Use only implements meeting the specifications listed in this manual or implements approved by KUBOTA. (See IMPLEMENT LIMITATIONS on page 25.)
• 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.

not modify the tractor. Unauthorized modification may affect the function of the tractor, which may result in personal injury.
2. CAB and ROPS
• KUBOTA recommends the use of a CAB or roll over protective 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.
• Set the parking brake and stop the engine. Remove any obstructions that may prevent the ROPS from rising or folding. Do not allow any bystanders near the tractor. Always perform the adjustment from a stable position at the rear of the tractor. Hold the top of the ROPS securely when raising or folding. 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 may weaken the structure.
• A damaged CAB or ROPS structure must be replaced, not repaired or revised.
• If any structural member of the CAB or ROPS is damaged, replace the entire structure at your local KUBOTA Dealer.

the tractor is equipped with a foldable ROPS, it may be temporarily lowered only when absolutely necessary for areas with height constraints. There is no operator protection provided by the ROPS in the lowered position. For operator safety, the ROPS should be placed in the upright and locked position and the seat belt fastened for all other operations.

OPERATING THE TRACTOR
Operator safety is a priority. Safe operation, specifically with 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, loads carried too high and so on. 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.
1. Starting to operate the tractor
respect to overturning hazards, entails
• Always engine or operating levers or controls. Adjust seat per instructions in the operating the tractor section. Never start engine while standing on the ground.
• 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.

84.)
Follow the recommendations for proper ballasting.
• To avoid free wheeling: – Do not shift the shuttle lever while on a slope. – Stop completely by using the brakes and by
depressing the clutch pedal, then shift the shuttle lever.
– Start off after selecting shuttle direction, by
releasing the clutch pedal.
• When driving down a slope, ensure that 4-wheel
drive is engaged to increase traction.
5. Driving the tractor on the road
• Lock
the 2 brake pedals together to help assure straight-line stops. Uneven braking at road speeds could cause the tractor to tip over.
4. Operating on slopes
Slopes are a major factor related to loss-of-control and tip-over death. All slopes require extra caution.
• To avoid upsets, always back up steep slopes. If

a steep slope increases the risk of rear rollovers. 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.

• Observe all local traffic and safety regulations.
• Turn the headlights on. Dim them 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 upright 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.
• Do not ride or stand on the step during operation. Riding or standing there could result in being crushed under the rear tire due to slippage or the step fracturing or being displaced by the unintended load.

PARKING THE TRACTOR
• Disengage 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.
• Make sure that the tractor has come to a complete stop before dismounting.
• Avoid parking on steep slopes. If at all possible, park on a firm and level surface; if not, 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.

• 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.
• 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.

Your dealer has knowledge of your new tractor and has the desire to help you get the most value from it. After
reading this manual thoroughly, you will find that you can do some of the regular maintenance yourself. However, when in need of parts or major service, be sure to see your KUBOTA Dealer. For service, contact the KUBOTA Dealership from which you purchased your tractor or your local KUBOTA Dealer.
