HOW TO TROUBLESHOOT TRACTOR PROBLEMS
GENERAL
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.
PRECAUTIONS BEFORE OPERATING THE TRACTOR
Know your equipment and its limitations. Read this entire manual before attempting to start and operate the tractor.
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. Carefully check the vicinity of the tractor before operating it or any implement attached to it. Do not allow any bystander around or near the tractor during operating it. Before allowing other people to use your tractor, explain them how to operate it and have them 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 anytime. 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
Keep your tractor clean. Buildups 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, FRONT LOADER, and WEIGHT OF THE IMPLEMENTS BALLAST or 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. Do not modify the tractor. Unauthorized modification may affect the function of the tractor, which may result in personal injury.
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.
Check for overhead clearance which may interfere with a CAB or ROPS. Set parking brake and stop engine. Remove any obstructions that 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. 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 is equipped with 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. Pull only from the hitch. Never hitch to axle housing or any other point except hitch. Hitching to axle housing or any other point except hitch will increase the risk of serious personal injury or death due.
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. Precautions for starting to operate the tractor. Always sit in the operator's seat when starting the engine or operating levers or controls. Adjust seat per 1. Operator's seat Never start the engine while you are 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 the power take-off (PTO) is disengaged or off. Fasten the seat belt if the tractor is equipped with a CAB, a fixed ROPS, 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 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 as 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 do before you do 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 trailed vehicle unless parking brake is applied. Do not operate or tow at speeds exceeding specific travel speed. 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 area is clear. 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 changing gears speed when the tractor is climbing or going down a slope. Changing gears to neutral on a slope 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, follow recommendations for proper ballasting as shown in BALLAST. When driving down a slope, make sure that 4-wheel drive is engaged to increase traction if equipped. Precautions for driving the tractor on the road. Check the front wheel engagement. 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 hazard lights and turn signals as required. On public roads, use the SMV emblem and hazard lights, if required by local traffic and safety regulations. Check 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. Set the implement-lowering-speed-knob in the lock Brake pedal Parking brake pedal Depress Push down parking brake pedal while depressing brake pedal. 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.
PRECAUTIONS FOR OPERATING THE PTO
Wait until all moving components have completely stopped before getting off the tractor, connecting, disconnecting, adjusting, cleaning, or servicing. Keep the PTO-shaft-cover in place at all times. Replace the PTO-shaft-cap when the shaft is not in use.
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 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. 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 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. When transporting loads on the road, set the implement-lowering-speed-knob in the lock position to hold the implement in the raised position.
PRECAUTIONS FOR SERVICING THE TRACTOR
Before servicing the tractor, park it on a firm, flat, and level surface and set the parking brake. Do not attempt to mount a tire on a rim. A qualified person should mount a tire on a rim with the proper equipment.
Always maintain the correct tire pressure. Do not inflate tires above the recommended pressure shown in Inflation pressure of tires. Allow the tractor time to cool off before working on or near the engine, muffler, radiator. Do not remove radiator cap while coolant is hot. When coolant is 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. Do not add coolant to the radiator. See Checking the coolant level. Always stop the engine before refueling. Avoid spills and overfilling.
Do not smoke when working around battery or when the tractor is 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 you are recharging it. Before jump starting a dead battery, read and follow all of the instructions. See JUMP STARTING THE ENGINE. Keep first-aid-kit and fire extinguisher handy at all times. Disconnect the battery's ground cable before working on or near electric components. To avoid sparks from an accidental short circuit, always disconnect the battery's ground cable (-) first and reconnect it last. Securely support the tractor when either changing wheels or adjusting the wheel tread width. Make sure that wheel bolts have been tightened to the specified torque. See WHEEL TREAD. 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 has sufficient force to penetrate skin, so escaping hydraulic fluid under pressure can cause 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.
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. Keep safety labels clean and free from obstructing material. Clean safety labels with soap and water, and dry with a soft cloth. Replace damaged or missing safety labels with new safety labels from your local KUBOTA Dealer. If a component with safety label(s) attached is replaced with new component, make sure that new safety label(s) is (are) attached in the same location(s) as the replaced component. Attach new safety labels by applying on a clean, dry surface and pressing any bubbles to outside edge.

KUBOTA TRACTOR RECOMMENDED OILS, FUEL, AND COOLANT
Fuel Cetane number of 45 is minimum. Cetane number greater than 50 is preferred, especially for the following temperatures or the following elevations. Diesel fuels specified to EN 590 or ASTM D975 are recommended. No.2-D is a distillate fuel of lower volatility for engines in industrial and heavy mobile service (SAE J313 JUN87). Engine oil 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 in the preceding table. Use the suitable API classification engine oil according to the engine type with internal EGR, external EGR, or non-EGR, and the fuel.
Transmission oil
KUBOTA Super UDT-2 For an enhanced ownership experience, we highly recommend Super UDT-2 to be used instead of standard hydraulic/transmission fluid. Super UDT-2 is a proprietary KUBOTA formulation that delivers superior performance and protection in all operating conditions. Regular UDT is also permitted for use in this machine.
Biodiesel fuel (BDF) B0-B20 biodiesel fuels (BDF) You can use mixed diesel fuels containing 20% or less biodiesel under the following conditions. IMPORTANT : Concentrations greater than B5 (5%) are not approved for common rail engines and engines with aftertreatment device. Using concentrations greater than B5 (5%) can cause damage and reduce engine life. Refuel and use the fuel with caution in order to avoid contact with the fuel and spillage that could create a potential environmental or fire hazard. Wear appropriate protective equipment when refueling. You can use blended diesel fuels containing 6% through 20% BDF (B6-B20) which comply with American society for testing and materials (ASTM) D7467 standard, as revised, without adversely affecting the performance and durability of the engine and the components of the fuel system. Any mineral-oil-diesel-fuel, if used, must conform to ASTM D975 (or the European EN590) Standard, as revised. B100 fuel used to generate biodiesel-blended-fuels must meet ASTM D6751 (or EN14214) Standard, as revised. The final blended fuel B20 must conform to ASTM D7467 standard, as revised. Straight-vegetable-oil is not allowed in any blended fuel. Allowable blended fuel is mineral-oil-diesel-fuel blended with B100 (for example 100% BDF). The blended fuel ratio shall be less than 20% B100 and 80% or more diesel fuel. Purchase the B100 source used for biodiesel blends from an accredited BQ-9000 marketer or producer. You can find more information about qualified marketer(s) and producer(s) at http:// www.bq-9000.org . Product warranty, emission, and other precautions The engine-emission-control-system was certified according to current regulations based on the use of non-BDF. When using BDF, the owner is advised to check applicable local and federal emission regulations, and comply with all of them. BDF may cause restricted or clogged fuel filters during cold weather conditions, resulting in the engine not operating properly. BDF encourages the growth of microorganisms which may cause degradation of the fuel. degradation of the fuel may cause corrosion of the fuel line or reduce the fuel filter flow earlier than expected. BDF inherently absorbs moisture which may cause degradation of the fuel earlier than expected. To avoid absorbing moisture of BDF, drain the water separator and the fuel-filter-port often. Do not use biodiesel whose concentrations higher than 20% (for example, greater than B20). Higher concentrated biodiesel will affect engine performance and fuel consumption, and degradation of the fuel system components may occur. Do not readjust the engine-fuel-control-system because readjusting it will violate the emission- control-levels for which the equipment was approved. Compared with soybean-based and rapeseed- based feedstock, palm-oil-based feedstock has a thicker consistency (for example, higher viscosity) at lower temperatures. Consequently, palm-oil-based feedstock may reduce performance of the fuel filter, particularly during cold weather conditions. The KUBOTA warranty, as specified in the Owner's Warranty Information Guide, only covers flaws in product materials and workmanship. Accordingly, The KUBOTA warranty do not cover any problems that may arise due to the use of poor quality fuels that fail to meet the preceding requirements, whether biodiesel or mineral-oil-based. Avoid spilling BDF onto painted surfaces because this may damage the finish. If the fuel is spilled, immediately wipe clean and flush with soapy water to avoid permanent damage. When using BDF, you are advised to maintain a full tank of the fuel, especially overnight and during short term storage, to reduce condensation within the tank. Be sure to tighten the fuel cap after refueling to prevent moisture build up within the tank. Water in the biodiesel mixture will damage the fuel filters and may damage the engine components. Maintenance Requirements when using BDF B0 through B5, be sure to ollow the oil-change-intervals recommended by referring to the SERVICE INTERVALS Extended oil-change-intervals may result in premature wear or engine damage. BDF easily deteriorates due to oxygen, water, heat, and foreign substances. Do not store B5 longer than three months. When using B5 fuel and storing the machine longer than three months, drain the fuel from the tanks and replace with light-mineral-oil-diesel-fuel. Subsequently, run the engine at least the following minutes to remove all of the biodiesel from the fuel lines. BDF easily deteriorates due to oxygen, water, heat, and foreign substances. Do not store B6 through B20 longer than one month. When using B6 through B20 fuel and storing the machine longer than one months, drain the fuel from the tanks and replace with light-mineral-oil- diesel-fuel. Subsequently, run the engine at least the following minutes to remove all of the biodiesel from the fuel lines. For your own safety and maximum service life of the machine, make a thorough daily inspection before operating the machine or starting the engine.
Checking the engine oil level
IMPORTANT : When using an engine oil of different maker or viscosity from the previous one, remove all of the old oil and oil filter. Never mix two different types of oil.If the engine oil level is low, do not run the engine.Park the machine on a firm, flat, and level surface. Check the engine oil before starting the engine, or, after five minutes or more when the engine has been stopped. To check the engine oil level, draw out the dipstick, wipe it clean, replace it, and draw it out again. Check to see that the engine oil level lies between the two notches. If the engine oil level is too low, add new oil to the prescribed level at the oil inlet. See LUBRICANTS, FUEL, AND COOLANT
Checking the transmission fluid level
IMPORTANT : If the transmission fluid level is low, do not run the engine. To check the transmission fluid level, check the dipstick as the following procedure. Draw out the dipstick. Wipe the dipstick clean. Replace the dipstick. Draw the dipstick out again. Check to see that the transmission fluid level lies between the two notches. If the transmission fluid level is too low, add new fluid to the prescribed level at the oil inlet.
COOLANT
If the radiator cap has to be removed, follow the preceding warning and securely retighten the radiator cap. Use clean, fresh, soft water and anti-freeze to fill the recovery tank. If water should leak, consult your local KUBOTA Dealer. Check to see that the coolant level is between the “H” and “L” marks of the recovery tank. When the coolant level drops due to evaporation, add soft water only. In case of leakage, add antifreeze and soft water in the specified mixing ratio up to the “H” level. See 1. Flushing the cooling system and changing the coolant. The panel and the radiator screen must be clean from debris to prevent the engine from overheating and to allow good air intake for the air cleaner. Be sure to reinstall the panel on the pillar completely to prevent the invasion of dust. Be sure to stop the engine to avoid personal injury and to allow good air intake for air cleaner. Check the panel and the radiator screen to be sure that they are clean from debris. Detach the radiator screen, and then remove all the foreign material. If the dust or chaff is accumulated in the battery compartment, open the panel and clean completely. Checking the head light, hazard light. Inspect the lights for broken bulbs and lenses. Replace the lights if they are broken.
Checking the seat belt and the ROPS
Always check condition of the seat belt and the ROPS attaching hardware before operating the tractor. Replace the seat belt or the ROPS if it is damaged. Checking the brake pedal Inspect the brake pedal for free travel, and smooth operation. Adjust the brake pedal if incorrect measurement is found.
Checking the gauges, the meters, and the Easy Checker™. Inspect the instrument panel for broken gauge(s), meter(s) and Easy Checker™ lamps. Replace the gauge(s), the meter(s), or the Easy Checker™ if they are broken. Inspect the following check items regularly. Check the wiring for chafed or cracked insulation. Check the wiring harness clamps. Replace them if necessary. Check the connectors and the terminals for looseness, contamination, or overheated or discolored connections. Check the instrument panel for correct operation of the switches and the gauges. Consult your KUBOTA Dealer regarding maintenance, diagnosis, and repair.
Checking Parts
If any of the movable parts, such as levers and pedals, is not smoothly moved because of rust or sticky material, remove the rust or the sticky material, and apply oil or grease on the relevant spot. Do not force the movable parts into motion. Otherwise, the machine may get damaged.
SERVICE EVERY 50 HOURS
Lubricate fittings with grease. Apply a small amount of multipurpose grease to the following points every 50 hours. If you operated the machine in extremely wet and muddy conditions, lubricate grease fittings more often. Apply grease between rod and hole. Sit on the operator's seat. Set the parking brake and stop the engine. Shift the range-gear-shift-lever to the neutral “N” position. Check whether the speed-control-pedal is in the neutral position. Shift the PTO-clutch-lever to the off position. [Test 1] Switch for the speed control pedal Make sure that the range-gear-shift-lever is set in the neutral “N” position. Depress the speed-control-pedal. Turn the key to the start position. The engine must not crank. If the engine cranks, consult your local KUBOTA Dealer. [Test 2] Switch for the PTO clutch lever. Make sure that the range-gear-shift-lever is set in the neutral “N” position. Make sure that the speed-control-pedal is set in the neutral position. Shift the PTO-clutch-lever to the on position.
