1SAFE OPERATION
SAFE OPERATION
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. Also keep the engine and muffler clean all the time.
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, etc. are recommended.
6. Do not operate machine or any implement attached to it while under the influence of alcohol, drugs, or other substances or while fatigued.
7. 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.)
8. Keep the machine and attachments in good operating condition and keep safety devices in place and in proper working condition.
9. This machine is equipped with many safety devices. Do not attempt to remove or alter them.
10.Keep all shields and guards in place. Replace all missing or damaged items for your safety.
11.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.
12.Before allowing other people to use your machine, explain proper operation to them and have them read this manual before operation.
13.Never allow passengers or non-qualified operators on the machine at any time. You must operate the machine from the seat only.
14.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.
15.Keep your machine clean. Dirt, grease, and trash accumulations contribute to fires or lead to personal injury.
16.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.
17.Use only implements 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.
18.Follow the maintenance recommendations. See "MAINTENANCE " section.
19.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.
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.
1. BEFORE OPERATING
2. OPERATING
SAFE OPERATION2
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.
10.Shut the engine off and wait for all movement to stop before removing grass catcher or unclogging chute. [if equipped]
11.Know what is behind you before overriding the KRA system. Do not override the KRA system unless absolutely necessary and safe to do so. KUBOTA strongly recommends against overriding the KRA system.
12.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.
13.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.
14.Use only implements 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.
15.Do not operate the mower without the entire grass catcher or the discharge shield in place. Be aware of the mower discharge direction and do not point it at anyone.
16.Watch for traffic when operating near or crossing roadways.
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.
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.
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.
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.
(1) Hitch hole
DO
3SAFE OPERATION
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 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.
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.

OPERATING THE ENGINE14
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.
BWarm-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:
A Do not operate the machine under full load condition
until it is sufficiently warmed up.
Ambient temperature Warm-up time requirement
Higher than 0 (32 ) Approx. 5 minutes

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.
BChanging 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 serious injury or death: A Do not operate the mower without the deflector
shield in the down position nor the mulching cover in front.
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 or holes and small children. Use extra caution when a machine is equipped with Grass Catcher.
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.
To avoid personal injury: A Clear the work area of objects which might be
picked up and thrown by blades.
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.
ADJUSTING CUTTING HEIGHT

23OPERATING THE MOWER
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
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.

BBattery
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.
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.
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.
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".
(1) Battery
(1) Vent well (2) Separator (3) Electrolyte
(A) "HIGHEST LEVEL " (B) "LOWEST LEVEL"
PERIODIC SERVICE46
(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.)
BReplacing Air Cleaner Paper Element
[T1880] Every 100 hours of operation or annually replace the paper element if equipped with a precleaner. Check every 25 hours of operation or annually if not equipped with a
precleaner. (More often under extremely dusty or dirty conditions.)

BChecking and Replacing Blade
To avoid personal injury:
A Be sure to stop the engine and remove the key. A Blades may be sharp. When you handle blades,
wear heavy gloves or wrap end of blade with a rag.
C Checking
The blade cutting edges should be kept sharp at all times. Sharpen the cutting edges, if they resemble blade (B). Replace the blades if they appear similar to blade (C).
C Replacing
1. Remove the mower deck from the machine and turn it over to expose the blades.
2. Wedge a block of wood between the blade and mower housing as illustrated.
3. The bolt for black blade has right hand threads, turn counterclockwise to loosen. The bolt for red blade has left hand threads, turn clockwise to loosen.
A Use the proper size box or socket wrench to tighten or
loosen the blade mounting bolt.
A Black blade to be assembled at discharge deflector
(Black color) side. Red blade to be assembled at mower deck wall (Red color) side.
4. To sharpen the blades yourself, clamp the blade securely in a vise. Use a large mill file and file along the original bevel until sharp.
5. To check the blade for balance, place a small rod through the center hole. If the blade is not balanced, file the heavy side of the blade until balance is achieved.
6. To attach blades, be sure to install the cup washer between the blade and bolt head.
A Make sure that the cup washer is not flattened out or
worn; this may cause blade to slip excessively. Replace the cup washer if either is damaged.

55STORAGE
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.
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.
