SAFE OPERATION 1
Careful operation is your best insurance against an accident. Read and understand this section carefully before operation.
All operators, no matter how experienced they may be, should read this and other related manuals before operation of the machine or any implement attached to it. It is the owner's obligation to instruct all operators in safe operation.
This cutting machine is capable of amputating hands and feet and throwing objects. Failure to observe the following safety instructions could result in serious injury or death.
1. Know your equipment and its limitations. Read, understand and follow all instructions in this manual before attempting to start and operate the machine.
2. Know the controls and how to stop quickly.
3. Pay special attention to the safety labels on the machine and mower.
4. The exhaust gas from the muffler is very hot. To prevent fire, do not expose dry grass, mowed grass, oil or any other combustible materials to exhaust gas.
Use a spark arrester where required. Also keep the engine and muffler clean all the time. Replace the muffler if it has a fault.
5. Never wear loose, torn, or bulky clothing. It may catch on moving parts or controls, leading to the risk of accident. Safety boots or shoes, eye and hearing protection, gloves, dust mask, etc. are recommended.
6. While mowing, always wear substantial foot wear and long trousers. Do not operate the equipment when barefoot or wearing open sandals.
7. Do not operate machine or any implement attached to it while under the influence of alcohol, drugs, or other substances or while fatigued.
8. Check brakes, and other mechanical parts for faulty 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 the machine and attachments in good operating condition and keep safety devices in place and in proper working condition.
10. This machine is equipped with many safety devices.
Do not attempt to remove or alter them.
11. Keep all shields and guards in place. Replace all missing or damaged items for your safety.
12. Never allow any bystanders around or near machine during operation.
Be sure the area is clear of other people before mowing.
Stop machine if anyone enters the area.
13. Before allowing other people to use your machine, explain proper operation to them and have them read this manual before operation.
14. Never allow passengers or non-qualified operators on the machine at any time. You must operate the machine from the seat only.
15.Carefully check the area to be mowed and clear any objects such as rocks, bottles, cans, toys, etc., that may damage the mower, the grass catcher or cause personal injury.
16.Keep your machine clean. Dirt, grease, and trash accumulations contribute to fires or lead to personal injury.
17.Keep all nuts, bolts, and screws tight to be sure the equipment is in safe working condition.
Check the mower blade mounting bolts for proper tightness at frequent intervals. On multi-bladed mowers, take care as rotating one blade can cause other blades to rotate.
18.Use only attachments recommended by KUBOTA.
Use proper ballast to front or rear of machine to reduce the risk of upsets. Follow the "Safe Operation" procedures, specified in the Equipment's Manual.
19.Follow the maintenance recommendations. See
"MAINTENANCE " section.
20.It is recommended that your machine be thoroughly inspected at least once a year by an authorized
KUBOTA Dealer.
C Starting
1. Never start engine or operate levers from anywhere other than the seat.
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 mower clutch and the Power Take-Off (PTO) are disengaged.
3. Do not start engine by shorting across starter terminals or by by-passing the safety start switch. The machine may start and move if normal starting circuitry is bypassed.
4. Do not operate or idle engine in a poorly ventilated area. Exhaust contains poisonous carbon monoxide, a colorless and odorless gas.
C Working
1. Watch where you are going at all times. Watch for and avoid obstacles. Be alert near trees and other obstructions.
2. When working in groups, always let others know what you are doing ahead of time.
2 SAFE OPERATION
3. Never try to get on or off a moving machine.
4. When using any attachments, never direct discharge material toward bystanders. Do not allow anyone near the attachments while in operation.
Do not mow when bystanders are present in the mowing area.
5. To reduce fire hazards, keep the engine exhaust area free of grass or leaves.
6. Slow down before turning.
7. Turn off blades when not mowing.
8. Mow only in daylight.
9. Be sure rotating blades and engine are stopped and the key is removed before placing hands or feet near blades and cleaning blockages or unclogging chute.
10. Know what is behind you and disengage power to mower before backing up. Do not mow while in reverse unless absolutely necessary and only after observation of the entire area behind the mower.
11. When mowing for the first time, cut the grass higher than desired.
This will uncover any unseen object that may damage the mower or grass catcher.
12. Always inspect the mower and grass catcher after striking any foreign object. This will insure that all mower and grass catcher parts are safe and secure and not damaged.
Repair or replace any damaged parts before restarting.
13. Use only attachment recommended in this manual.
Use proper ballast to front or rear of machine to reduce the risk of upsets. Follow the "SAFE OPERATION" procedures specified in the manuals included with the equipment.
14. Do not operate the mower without either the grass container or the guard in place.
Be aware of the mower discharge direction and do not point it at anyone.
15. Watch for traffic when operating near or crossing roadways.
16. Stop the blades rotating before crossing surface other than grass.
17.Never leave a running machine unattended.
Always turn off blades, set parking brake, stop engine, and remove the key before dismounting.
18.Be extremely alert for all other traffic when operating the mower and grass catcher near public roads or highways.
19.Do not operate where machine could tip or slip.
Do not operate near ditches, holes, embankments, or other terrain which may collapse under the machine's weight. The risk of machine tip-over is increased when the ground is loose or wet.
20.Raise and dump collected leaves or grass clippings
ONLY while sitting on the operator's seat.
21.Empty the grass container ONLY from a firm and level surface, with the mower stopped, and the unit stationary. Dumping the grass container on soft or uneven ground, or while moving, could cause the unit to tip over, causing serious injury and extensive equipment damage.
22.Make sure the dumping area is clear of all bystanders and pets, before emptying grass clippings or leaves from the grass container.
23.If the machine starts to vibrate abnormally, disengage the drive to the attachments, stop the engine and remove the key. Then check the machine immediately.
24.With the grass container raised, do not run the machine too fast, on slopes, nor make a sharp turn.
Otherwise the machine may turn over.
25.Keep hands away from the grass container, while lowering it. Otherwise they may get caught.
C Pulling loads
Use extra care when pulling loads to reduce the risk of serious personal injury or death due to a machine tip-over.
a) Pull only from the hitch. Never attach loads to the axle
housing or any other point above hitch.
b) Limit loads to those you can safely control.
c) Do not turn sharply.
d) Use care when backing.
e) Use front ballast or wheel weights when suggested in
this Operator's Manual.
C Operation 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. If you cannot back up the slope or if you feel uneasy on it, do not mow it. The control of a ride-on machine sliding on a slope will not be regained by the application of the brake.
A Do not lift the grass container on a slope.
1. Mow up and down slopes, not across, to avoid machine tip-over. Stay off hills and slopes too steep for safe operation.
2. Remove obstacles such as rocks, tree limbs, etc.
3. Stay alert for holes in the terrain and other hidden hazards. Keep away from drop-offs. Uneven terrain could overturn the machine. Tall grass can hide obstacles.
4. Use slow speed.
5. Follow KUBOTA's recommendations for wheel weights or counterweights to improve stability.
6. The weight of grass in the grass container may increase the possibility of tip over.
7. Keep all movement on slopes slow and gradual. Do not make sudden changes in speed or direction.
8. Avoid starting or stopping on a slope. If tires lose traction, disengage the blades and proceed slowly straight down the slope.
9. If the machine stops going uphill, disengage PTO and back slowly down.
10. Reduce speed and exercise extreme caution on slopes and in sharp turns to prevent tip-over or loss of control.
11. Use special caution when changing direction on slopes.
1. Do not turn on slopes unless necessary and then turn slowly and gradually downhill, if possible.
2. Do not use the machine on slopes of more than 11 .
3. Do not mow near drop-offs, ditches, or embankments.
The machine could suddenly turn over if a wheel falls over the edge of a cliff or ditch, or if an edge caves in.
4. Do not mow on wet grass. Reduced traction could cause sliding.
5. Do not try to stabilize the machine by putting your foot on the ground.
6. Do not stop or start suddenly when going uphill or downhill.
7. Never "freewheel". Do not let the machine travel downhill with HST pedal at neutral position.
8. Do not modify or alter the riding mower.
C Children
Tragic accidents can occur if the operator is not alert to the presence of children. Children are attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them.
1. Keep children out of the mowing area and under the watchful care of another responsible adult.
2. Be alert and turn the machine off if children enter the area.
3. Before and when backing, look behind and down for small children.
4. Never carry children. They may fall off and be seriously injured or interfere with safe machine operation.
5. Never allow children to operate the machine, even under adult supervision. Local regulation can restrict the age of the operator.
SAFE OPERATION 3
6. Use extra care when approaching blind corners, shrubs, trees, or other obstructions that might hide children from sight.
C Operators, age 60 years and above
Data indicates that operators, age 60 years and above, are involved in a large percentage of machine-related injuries. These operators should evaluate their ability to operate the machine safely enough to protect themselves and others from serious injury.
C Stopping
1. Make sure that the machine has come to a complete stop before dismounting.
2. Before dismounting, disengage the PTO, lower all implements, place all control levers in their neutral positions, apply parking brake, turn off the engine and remove the key.
3. Do not park the machine on a steep incline. Park on relatively flat areas.
1. Before installing or using PTO-driven equipment, read the manufacturer's manual and review the safety labels attached to the equipment.
2. Wait until all moving components have completely stopped before connecting, disconnecting, adjusting, cleaning, or servicing any PTO-driven equipment.
3. Use the PTO with KUBOTA approved attachments.
1. Use lift link only with authorized attachments designed for lift link usage.
1. Disengage power to attachment(s) when transporting or not in use.
2. Do not tow this machine. Use a suitable truck or trailer when transporting on public roads.
3. It is recommended that this machine not be used on public roads.
4. Use extra care when loading or unloading the machine into a trailer or truck.
1. Before servicing the machine, park the machine on a firm, level surface, set the parking brake, stop the engine and remove the key.
4 SAFE OPERATION
2. Securely support machine or any machine elements with stands or suitable blocking before working underneath. For your safety do not rely on hydraulically supported devices, they may leak down, suddenly drop or be accidently lowered.
3. To avoid injury, do not adjust, unclog or service the mower or grass catcher with the engine running. Make sure rotating blades are stopped before dismounting the riding mower.
4. Disengage power to attachment(s), stop the engine and remove the key before making any repairs or adjustments.
5. Allow the machine to cool off before servicing the engine, muffler, etc.
6. Keep your riding mower clean. Dirt and grass build-up can cause fires and may lead to serious personal injury.
Periodically wash the grass container to insure the safety signs can be read.
Replace all safety signs that are damaged, lost or have otherwise become illegible. If a part to be replaced has a sign on it, obtain a new safety sign from your
KUBOTA Dealer and install it in the same place as on the removed part.
7. Use extra care in handling diesel fuels. They are flammable.
(1) Use only an approved container.
(2) Do not remove fuel cap or refuel with the engine running. Allow engine to cool before refueling. Do not smoke while refueling or when standing near fuel.
(3) Do not refuel the machine indoors and always clean up spilled fuel or oil.
(4) Do not store the machine or fuel container inside where there is an open flame, such as in a water heater.
(5) If the fuel tank has to be drained, this should be done outdoors.
(6) Replace all fuel tanks and container caps securely
8. Do not change the engine governor setting or overspeed the engine. Operating the engine at excessive speed can increase the hazard of personal injury.
9. Never run a machine inside a closed area.
10. Mower blades are sharp and can cut your hands. Wrap the blade(s) or wear gloves, and use extra caution when servicing them.
11. Keep nuts and bolts, especially blade attachment bolts, tight and keep equipment in good condition. On multi-bladed mowers, take care as rotating one blade can cause other blades to rotate.
12. Do not smoke when working around the battery.
Keep all sparks and flames away from battery. The battery presents an explosion hazard because it gives off hydrogen and oxygen...especially when recharging.
13.Before "JUMP STARTING" a dead battery, read and follow all of the instructions to help protect the alternator from damage due to extreme load changes.
(See "JUMP STARTING" in "OPERATING THE
ENGINE" section.)
Batteries contain sulfuric acid and produce explosive gases. Follow the instructions below to prevent personal injury.
A Wear eye and skin protection.
A Keep sparks and flame away.
A Always have adequate ventilation while charging or using the battery.
14.Keep first aid kit and fire extinguisher available at all times.
15.Disconnect the battery's negative (-) cable before working on or near electric components.

This fluid can produce gangrene or severe allergic reaction.
22. Securely support the machine when changing wheels.
23. Make sure that wheel bolts have been tightened to the specified torque.
24. Do not put yourself below the raised grass container.
25. Escaping hydraulic fluid under pressure has sufficient force to penetrate the skin causing serious personal injury. Before disconnecting lines, be sure to relieve all pressure. Before applying pressure to the system, make sure all connections are tight and that lines, pipes, and hoses are not damaged.
(1) Cardboard
(2) Hydraulic line
(3) Magnifying glass
27.Do not use beverage containers for waste fluids or other products. Someone, particularly children, may drink them by mistake.
28.Waste products such as used oil, fuel, hydraulic fluid, and batteries, can harm the environment, people, pets and wildlife. Please dispose properly.
29.See your local Recycling Center or KUBOTA Dealer to learn how to recycle or get rid of waste products.
A A Material Safety Data Sheet (MSDS) provides specific details on chemical products; physical and health hazards, safety procedures, and emergency response techniques. The seller of the chemical products used with your machine is responsible for providing the MSDS for that product upon request.

To avoid personal injury:
A Additional ballast will be needed for operating heavy attachments. When the attachment is raised, drive slowly over rough ground, regardless of how much ballast is used.
A Add front ballast to increase front end stability and help prevent possible front end tip up.
A Always back up when going up a slope. Driving forward could cause the machine to tip over backward. Stay off hills and slopes too steep for safe operation.
A Front weight kit must be installed for high dump grass catcher.
Front ballast is added for stability and steering control when heavy rear mounted equipment such as the rotary tiller is installed.
Front ballast also compensates for weight transferred to the rear wheels by the draft of towed implements through the hitch.
Add additional front ballast, if necessary, for stability and safety during transport of heavy rear mounted equipment.
Front end ballast may not always maintain the required stability if the machine is driven too fast over rough ground with heavy rear mounted equipment in the raised position.
Use care and drive slowly under these conditions.
Limit ballast to machine operating capacity. Be sure to remove ballast when it is not needed.
Add ballast to rear end if needed for stability. Heavy front mounted attachments tend to lift rear wheels. Add enough ballast to maintain steering control and prevent tipover.
The Attachment's Manual shows how much rear ballast is required for your application. Rear ballast are available from your KUBOTA Dealer.
IMPLEMENT LIMITATIONS 5

18 OPERATING THE ENGINE
To avoid personal injury:
A Be sure to apply the parking brake 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 part of the engine. If load should be applied to the engine without this warm-up period, problems may develop such as seizure, breakage or premature wear may develop.
B
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 create problems with the hydraulic system or a damage to the hydraulic clutch.
To prevent the above, observe the following instructions:
Warm up the engine at about 50% of rated rpm according to the table below:
Atmospheric temperature
Warm-up time requirement Higher
Higher than 0
-10 to 0
Approx. 5 minutes
5 to 10 minutes
-20 to -10
Below -20
10 to 15 minutes
More than 15 minutes
A Do not operate unless the engine is well warmed up. If operation is attempted while the engine is still cold, the hydraulic mechanism will not function properly and its service life will be shortened.
A If noises are heard after the hydraulic control lever has been activated and the implement is lifting, the hydraulic mechanism is not adjusted properly. Unless corrected, the unit will be damaged. Contact your local
KUBOTA Dealer for adjustment.
To avoid serious injury:
A Battery gases can explode. Keep cigarettes, sparks, and flames away from battery.
A If machine battery is frozen, do not jump start engine.
A Do not connect other end of negative (-) jumper cable to negative (-) terminal of machine battery.
When jump starting the engine, follow the instructions below to safely start the engine.
1. Bring helper vehicle with a battery of the same voltage as the disabled machine within easy cable reach.
"THE VEHICLES MUST NOT TOUCH".
2. Apply the parking brakes of both vehicles and put the shift levers in neutral. Shut the engine off.
3. Put on safety goggles and rubber gloves.
4. Ensure the vent caps are securely in place.
(if equipped)
5. 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.
6. Clamp the other cable to the negative (black, (-) or neg.) terminal of the helper battery.
7. Clamp the other end to the engine block or frame of the disabled machine as far from the dead battery as possible.
8. Start the helper vehicle and let its engine run for a few moments. Start the disabled machine.
9. Disconnect the jumper cables in the exact reverse order of attachment. (Steps 7, 6 and 5).
(1) Dead battery
(2) Jumper cables
(3) Engine block or frame
(4) Helper battery
Connect cables in numerical order.
Disconnect in reverse order after use.
A This machine has a 12 volt negative (-) ground starting system.
A Use only same voltage for jump starting.
A Use of a higher voltage source on machine could result in severe damage to machine electrical system.
Use only matching voltage source when "Jump starting" a low or dead battery condition.
OPERATING THE ENGINE 19
20 OPERATING THE MACHINE
How a new machine is operated and maintained will determine the life of the machine.
A new machine just off the factory production line has been tested, but the various parts are not accustomed to each other, so care should be taken to operate the machine 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 machine is handled during the "breaking-in" period greatly affects the life of your machine. Therefore, to obtain the maximum performance and the longest life of the machine, it is very important to properly break-in your machine. In handling a new machine, the following precautions should be observed.
B
The lubricating oil is especially important in the case of a new machine. The various parts are not "broken-in" and are not accustomed to each other; small metal grit may develop during the operation of the machine; 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
"SERVICE INTERVALS" in "MAINTENANCE" section.
To avoid serious injury:
A Do not allow any person other than the driver to ride on the machine.
A Do not drive the machine close to the edges of ditches or banks which may collapse under the weight of the machine, especially when the ground is loose or wet.
A Slow down before turning.
A To avoid tip over, operate up and down slopes, not across. Avoid sudden starts and stops on slopes. Slow down, and use extra caution when changing direction on a slope. Do not use the machine on steep incline.
Park the machine on a firm, level surface.
A Watch where you are going at all times. Watch for and avoid obstacles. Be alert at curbs, near trees, and other obstructions and hidden hazards.
A Do not drive a machine on streets or highways.
Watch for traffic when you cross roads or operate near roads.
A Look to the rear before and when backing.
Make sure the area immediately behind you is clear of obstructions, holes and small children.
Use extra caution when a machine is equipped with Grass Catcher.
B
After the first 50 hours of operation, change the engine oil and filter. (See "EVERY 100 HOURS" "EVERY 200
HOURS" in "PERIODIC SERVICE" section.)

OPERATING THE MOWER 29
1. When using your mower for the first time, choose a smooth level area and cut in straight and slightly overlapping strips.
2. The size and type of the area to be mowed will determine the proper mowing pattern. Take into account obstructions, such as trees, fences and buildings.
3. Most lawns should be mowed to keep the grass approximately 50 to 80 mm high. Best results are obtained by cutting often and not too short. To keep a green lawn, never mow more than one third of the height of the grass or a maximum of 25 mm in one mowing.
For extremely tall grass, set the cutting height at maximum cutting height for the first mowing, then reset to the desired height and mow again. Allow the grass to grow to 80 mm, then cut off only the top inch.
4. For best appearance, grass should be cut in the afternoon or evening when it is free of moisture.
To avoid serious injury or death:
A Do not operate mower in the "TOP" position.

A For best cut quality and performance, always mow with the throttle lever in the "FAST" position.
Use the speed control pedal to select the desired mowing speed range.
(1) During heavy duty use, operate the machine at slower ground speed or go over the area twice.
The first pass should be with the deck at the highest position then mow to desired height.
(2) The mower will not cut cleanly if the ground speed is too high or if the blade speed drops due to an overload.
(3) If the better collecting performance is needed on cutting at lower position, open the slot with moving the cover clockwise.
(1) Knob bolt
(2) Cover
(3) Slot
(A) "OPEN" (Move the cover clockwise)
A Slot should be closed on normal operation.
A Keep the mower deck in the fully raised position when the mower is not engaged.
To avoid serious injury or death:
A Engine components can get extremely hot from operation. To prevent severe burns, do not touch these areas while the engine is running, or immediately after it is turned off.
Never operate the engine with heat shields or guards removed.
32 OPERATING THE GRASS CATCHER
To avoid serious injury or death:
A Do not operate mower without grass catcher.
1. Overall grass collecting performance depends on the airflow from the mowing blades, through the ducts, into the grass container.
2. Mow and collect when the grass is dry and not too tall.
Never mow grass when it is wet or heavy with dew as the grass catcher duct may plug rapidly.
3. If the grass is unusually tall, mow and collect at a higher than desired height of cut.
Attempting to mow with the deck too low in tall grass will restrict intake air necessary for good collecting performance.
Tall grass clippings may also plug the ducts before the container is filled.
After tall grasses have been mowed, reset the mower to the desired height of cut and remow the area.
4. Always mow at full engine throttle. If the engine lugs down while mowing, reduce riding mower ground speed.
C Full Grass Buzzer
If grass gets stuck up to the grass sensor set position, the buzzer sounds. If the buzzer sounds, dump the grass inside of the bag.
5. During the mowing operation, when the lumps of the grass clippings begin to drop on the mowing track, the machine tells you that the discharging duct is plugged and the grass container is filled. In such cases, empty the container and clean the duct by operating the lever of the duct clean system to discharge the grass completely.
6. Thoroughly clean the mower deck, discharge duct and the container after each mowing. Grass build-up, left to dry, will be very difficult to remove, and if not removed, will effect future mowing and bagging performance.
To avoid personal injury:
A Raise and dump collected leaves or grass clippings ONLY while sitting on the Operator's
Seat.
A Empty the container ONLY from a firm and level surface, with the mower stopped, and the machine stationary. Dumping the container on soft or uneven ground, or while moving, could cause the machine to tip over, causing serious injury and extensive equipment damage.
A Make sure the dumping area is clear of all bystanders and pets, before emptying grass clippings or leaves from the container.
To empty:

To avoid personal injury:
A Do not clean the machine with engine running.
A Be sure to set the parking brake during cleaning.
The use of a high pressure cleaner is not recommended.
However if you use one, take care not to splash water on engine parts such as the air filter, exhaust muffler, battery.
Do not direct jet towards hydraulic elements.
The grass catching container must be cleaned after each use in order to allow optimum evacuation of air. This is done with a water jet.
A cutting system with a properly maintained collection container will cut and collect grass more efficiently.
After each use, carefully clean the mowing deck, particularly underneath. Switch the engine off before cleaning your machine.
The inside part of the mowing system can also be cleaned with water through the discharge duct.
Remove the grass container to access the discharge duct.
Operate the mowing system for a few minutes after cleaning.
Clean the grass buildup on the top of mower deck and gear case as shown in the figure.
A If the mower was used under very difficult conditions
(very wet grass, mowing in a very low position), it may be necessary to remove the cutting deck to clean it. At the same time, you should take the opportunity to check the condition of the blades, belts and bolts and replace them if needed.

A To prevent serious damage to hydraulic systems, use only KUBOTA genuine fluid or its equivalent.
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 lowsulfur 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).

---
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.

To avoid the possibility of battery explosion:
For the refillable type battery, follow the instructions below.
A Do not use or charge the refillable type battery if the fluid level is below the LOWER (lower limit level) mark. Otherwise, the battery component parts may prematurely deteriorate, which may shorten the battery's service life or cause an explosion. Check the fluid level regularly and add distilled water as required so that the fluid level is between the UPPER and LOWER levels.
To avoid serious injury or death:
A When the battery is being activated, hydrogen and oxygen gases in the battery are extremely explosive. Keep open sparks and flames away from the battery at all times, especially when charging the battery.

To avoid serious injury:
A Never remove the battery cap while the engine is running.
A Keep electrolyte away from eyes, hands and clothes. If you are spattered with it, wash it away completely with water immediately and get medical attention.
A Keep open sparks and flames away from the battery at all times. Hydrogen gas mixed with oxygen becomes very explosive.
A Wear eye protection and rubber gloves when working around battery.
The factory-installed battery is of non-refillable type.
If the battery is weak, charge the battery or replace it with new one.
To avoid serious injury or death:
A When the battery is being activated, hydrogen and oxygen gases in the battery are extremely explosive. Keep open sparks and flames away from the battery at all times, especially when charging the battery.
To avoid serious injury:
A When disconnecting the cable from the battery, start with the negative terminal first. When connecting the cable to the battery, start with the positive terminal first.
A Never check battery charge by placing a metal object across the posts.
Use a voltmeter or hydrometer.
A Mishandling the battery shortens the service life and adds to maintenance costs.
The original battery is maintenance free, but needs some servicing.
If the battery is weak, the engine will be difficult to start and the lights will be dim. It is important to check the battery periodically.
A When exchanging an old battery for new one, use battery of equal specification in table below.
62 PERIODIC SERVICE
(1) Battery
1. To slow charge the battery, connect the battery positive terminal to the charger positive terminal and the negative to the negative, then charge for at least 1 hour at 6.5 amperes.
2. A boost charge is only for emergencies. It will partially charge the battery at a high rate and in a short time.
When using a boost-charged battery, it is necessary to recharge the battery as early as possible.
Failure to do this will shorten the battery's service life.
3. When the specific gravity of electrolyte is between
1.27 and 1.29 the charging is completed.
C Battery for storage
1. When storing the tractor for a long period, remove the battery from tractor, adjust the electrolyte to the proper level and store in a dry place out of direct sunlight.

If it freezes, coolant can damage the cylinders and radiator. If the ambient temperature falls below 0 or before a long-term storage, let out cooling water completely, or mix fresh water with long-life coolant and fill the radiator and reserve tank with the mixture.
1. Long-life coolant (hereafter LLC) comes in several types. Use ethylene glycol (EG) type for this engine.
2. Before employing LLC-mixed cooling water, fill the radiator with fresh water and empty it again. Repeat this procedure 2 or 3 times to clean up the inside.
3. Mixing the LLC
Put the LLC in cooling water in the percentage (%) for a target temperature. When mixing, stir it up well, and then fill into the radiator.
4. The procedure for the mixing of water and anti-freeze differs according to the make of the anti-freeze and the ambient temperature. Refer to SAE J1034 standard, more specifically also to SAE J814c.

*Never add any long-life coolant of different manufacturer. (Different brands may have different additive components, and the engine may fail to perform as specified.)
6. When the LLC is mixed, do not employ any radiator cleaning agent. The LLC contains anti-corrosive agent. If mixed with the cleaning agent, sludge may build up, adversely affecting the engine parts.
7. Kubota's genuine long-life coolant has a service life of
2 years. Be sure to change the coolant every 2 years.
A The above data represent industry standards that necessitate a minimum glycol content in the concentrated anti-freeze.
76 PERIODIC SERVICE
A When the coolant level drops due to evaporation, add water only to keep the anti-freeze mixing ratio less than 50%. In case of leakage, add anti-freeze and water in the specified mixing ratio before filling in to the radiator.
