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.
DO
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 the KUBOTA's recommendations for wheel weights or counterweights to improve stability.
6. The weight of grass in the grass catcher 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.
SAFE OPERATION 3
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.
DO NOT
1. Do not turn on slopes unless necessary and then turn slowly and gradually downhill, if possible.
2. 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.
3. Do not mow on wet grass. Reduced traction could cause sliding.
4. Do not try to stabilize the machine by putting your foot on the ground.
5. Do not use grass catcher on steep slopes.
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 machine.
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.
6. Use extra care when approaching blind corners, shrubs, trees, or other obstructions that might hide children from sight.

14 OPERATING THE ENGINE
WARMING UP
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 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.
B
Warm-up and Transmission Oil in the 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:
Ambient temperature Warm-up time requirement
Higher than 0 (32 )
0 to -10 (32 to 14 )
-10 to -20 (14 to -4 )
Approx. 5 minutes
5 to 10 minutes
10 to 15 minutes
Below -20 (-4 ) More than 15 minutes
A Do not operate the machine under full load condition until it is sufficiently warmed up.

16 OPERATING THE MACHINE
OPERATING THE MACHINE
OPERATING NEW MACHINE
How a new machine is operated and maintained determines the life of the machine.
A new machine 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 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.
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 or holes and small children. Use extra caution when a machine is equipped with Grass Catcher.
B
Changing Lubricating Oil for New
Machines
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 personal injury:
A
Clear the work area of objects which might be picked up and thrown by blades.
A
Do not direct the opening of the chute at bystanders or animals. Ejected objects may cause injury. Plan your mowing carefully before starting operation.
A
Keep bystanders especially children and animals away from the mowing area.
A
Be sure to disengage the PTO and sit on the operator's seat before starting the engine.

22 OPERATING THE MOWER
OPERATING THE MOWER
MAKING THE MOST OF YOUR MOWER
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. To keep grass clippings off fences, sidewalks, etc., it is advisable to go over the outside of the area to be mowed several times in a clockwise direction. To mow the area remaining, work in a counterclockwise direction so that the clippings are dispersed onto the previously cut area.
3. Always keep the left side of the mower toward trees, posts or other obstacles on the first trip around the obstacle.
4. Most lawns should be mowed to keep the grass approximately 50 to 80 mm (2 to 3 in.) 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 (1 in.) 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 (3 in.), then cut off only the top inch.
5. For best appearance, grass should be cut in the afternoon or evening when it is free of moisture.
ADJUSTING CUTTING HEIGHT
To avoid serious injury or death:
A
Do not operate mower in the "TOP" position.
B
Cutting Height Control Dial
Raise the lift lever to the top position. Turn the cutting height control dial to the desired cutting height. Then lower the lift lever and the mower deck will be set to the cutting height.

A
Keep bystanders and animals away from the mowing area.
A
Be sure to disengage the PTO and sit on the operator's seat before starting the engine.

4. Set the anti-scalp rollers' height as shown to keep clearance between rollers and ground more than 6 mm (0.25 in.).
5. Lower the mower deck by pushing the mower lift lever downward. This lowers the mower deck from the
"TOP" position to the "OPERATING" position.
6. Use the higher settings for mowing in a rough area or when mowing tall grass. Lower settings should be used only for smooth lawns where short grass is desired.
OPERATING THE MOWER 23
OPERATING THE MOWER
A
This machine is equipped with the KRA (KUBOTA
Reverse Awareness) system.
This feature shuts down the engine if the operator attempts reverse travel while any PTO driven implement is engaged. The purpose of the KRA system is to increase operator awareness of the risk of back-over accidents. The KRA system incorporates an override switch on the dash that allows the operator to override the system and keep the PTO engaged during reverse travel. KUBOTA strongly recommends against overriding the KRA system, but if the operator deems it absolutely necessary and safe to do so, he may activate the override switch. The override switch light flashes while activated as a reminder to the operator that the PTO (i.e. mower, grass catcher, snowblower, etc.) remains engaged during reverse travel. The operator should return the KRA system to normal operating mode as soon as possible by momentarily disengaging the PTO.

Battery
To avoid personal injury:
A
Never remove the vent cap while the engine is running. 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
Wear eye protection and rubber gloves when working around battery.
Mishandling the battery shortens the service life and adds to maintenance costs.
The original battery is a maintenance-free, nonaccessible type battery.
If the battery is weak, the engine will be difficult to start and the lights will become dim. It is important to check the battery periodically.
To avoid personal injury:
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.
A
When charging battery, ensure that the vent caps are securely in place (if equipped).
A
When disconnecting the cables from the battery, start with the negative terminal first.
When connecting the cables 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.
(For accessible maintainable type batteries with removable vent caps.)
1. Make sure each electrolyte level is at the bottom of vent wells, if necessary add distilled water in a wellventilated area.

C
Battery Charging
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.
(1) Vent well
(2) Separator
(3) Electrolyte
(A) "HIGHEST LEVEL "
(B) "LOWEST LEVEL"
2. The water in the electrolyte evaporates during recharging. Liquid shortage damages the battery.
Excessive liquid spills over and damages the machine body.
3. To slow charge the battery, connect the battery positive terminal to the charger positive terminal and the negative to the negative, then recharge in the standard fashion.
4. A boost charge is only for emergencies. It will partially charge the battery at a higher rate and in a short time.
When using a boost-charged battery, it is necessary to recharge the battery as soon as possible.
Failure to do this will shorten the battery's service life.
5. When the specific gravity of electrolyte reaches
1.27~1.29 charge has completed.
6. When exchanging an old battery with new one, use a battery of equal specification shown in
"SPECIFICATIONS".
46 PERIODIC SERVICE
(For non-accessible maintenance-free type batteries.)
Maintenance-free, non-accessible batteries are designed to eliminate the need to add water. Yet the volume of electrolyte above plates may eventually become depleted due to abnormal conditions such as high heat or improper regulator setting. Use a voltmeter to check the state of charge. (See reference chart below to determine if charging is necessary.)

STORAGE 55
STORAGE
To avoid personal injury:
A
To reduce fire hazards, allow the engine and exhaust system to cool before storing the machine in an enclosed space or near combustible materials.
A
To avoid the danger of exhaust fume poisoning, do not operate the engine in a closed building without proper ventilation.
A
Do not clean the machine with engine running.
A
To avoid fire hazards, Do not leave grass and leaves in the mower and the grass catcher.
A
When storing, remove the key from the key switch to avoid operation by unauthorized persons.
When the machine will not be operated for over two months, clean the machine and perform the following operations before storage.
1. Repair parts as necessary.
2. Check bolts and nuts and tighten as necessary.
3. Apply grease or engine oil to parts most likely to rust.
4. Inflate the tires to a little above the standard pressure levels. (Approximately 110%)
5. Lower the mower to the ground.
6. Remove the battery from the machine, recharge it, adjust the electrolyte to the proper level, and store in a cool dry place.
The battery discharges over time even while in storage. Recharge it once a month in hot seasons and once every two months in cold seasons.
7. Drain fuel tank, fuel lines, and carburetor, or use a fuel stabilizer, to prevent deterioration of the gasoline. If you choose to use a fuel stabilizer, follow the manufacturers recommendations, and add the correct amount for the capacity of the fuel system. Fill the fuel tank with clean, fresh gasoline. Run the engine for 2 to
3 minutes to get stabilized fuel into the carburetor.
8. Store the machine where it is dry and sheltered from rain. Cover the machine with a vinyl tarp.
9. Moisture content in most grasses can damage the mower and grass catcher if these components are not properly cleaned after use.
Make sure the mower and the grass catcher are clean and completely empty before storage.
REMOVING THE MOWER FROM STORAGE
1. Check the tire inflation pressure and adjust as required.
2. Install the battery. Before installing the battery, be sure it is fully charged.
3. Do daily checking. (See "DAILY CHECK" in
"PERIODIC SERVICE" section.)
4. Check all fluid levels. (engine oil, hydrostatic oil)
5. Start the engine. Shut the engine off and walk around the machine and make a visual inspection looking for evidence of oil or other fluids.
6. Run engine a couple of minutes before you put engine under load.
7. With the engine fully warmed up, release the parking brake and test the brakes for proper adjustment as you move forward. Adjust the brakes as necessary.
