SAFE OPERATION

Careful operation is your best insurance against an accident. The owner/user can prevent and is responsible for accidents or injuries occurring to themselves, other people or property. Read and understand this manual carefully before operating the machine. All operators, no matter how much experience they may have had, must read this and other related manuals before operating the machine or any implement attached to it. It is the owner's obligation to instruct all operators in safe operation. If the operator(s) or mechanic(s) cannot read English it is the owner's responsibility to explain this material to them. This mowing 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. BEFORE OPERATING

1. The ZERO TURN MOWING MACHINE has different steering characteristics than other machines with a steering wheel and does not have a service brake pedal (but, has a parking brake lock pedal that can be used to stop the machine in an emergency. Normal slowing down and stopping is done with the motion control levers.). Read and understand the operators manual before operating the machine. Practice operating machine at low engine speed without mower engaged in an unobstructed area.

2. Know your equipment and its limitations. Read all instructions in this manual before attempting to start and operate the machine.

3. Pay special attention to the danger, warning and caution labels on the machine itself.

-1SAFE OPERATION

ENGLISH

4. The ROPS is an integral and effective safety device. KUBOTA recommends the use of a Roll Over Protective Structures (ROPS) and seat belt in almost all applications. This combination will reduce the risk of serious injury or death, should the machine be upset. The machine is equipped with a Foldable ROPS, which may be temporarily folded down only when absolutely necessary for areas with height constraints. There is no operator protection provided by the ROPS in the folded position. For operator safety you must set the ROPS in the upright and locked position and put on the seat belt for all other operations. DO NOT remove the ROPS. If the ROPS is loosened or removed for any reason, make sure that all parts are reinstalled correctly before operating the machine. Never modify or repair a ROPS because welding, bending, drilling, grinding, or cutting may weaken the structure. If any structural member of the ROPS is damaged, replace the entire structure at your local KUBOTA Dealer. Any alterations to a ROPS must be approved by the manufacturer. Check the area to be mowed and never fold down a folding ROPS in areas where there are slopes, drop offs or water. Check carefully for overhead clearances (i.e. branches, doorways, electrical wires) before driving under any objects and do not contact them. Keep the ROPS in safe operating condition by periodically thoroughly inspecting for damage and keeping all mounting fasteners tight.

(1) ROPS (2) Seat belt

SAFE OPERATION-2

5. Always use the seat belt when the ROPS is upright. Do not use the seat belt if the ROPS is down or if there is no ROPS. Check the seat belt regularly and replace if

ENGLISH

frayed or damaged. Be certain that the seat belt can be released quickly in the event of an emergency.

6. Do not operate the machine or any attachments while under the influence of alcohol, medication, controlled substances or when fatigued.

7. Do not wear loose, torn, or bulky clothing around machine. The clothing may catch on moving parts or controls, leading to the risk of accident. Wear and use any additional safety items such as hard hat, safety boots or shoes, eye and hearing protection, gloves, etc., as appropriate or required.

8. Do not wear radio or music headphones while operating the machine. Safe operation requires your full attention.

9. Carefully check the vicinity before operating machine or any implement attached to it. Clear the work area of objects (wires, rocks, etc.) that might be picked up and thrown. Check for overhead clearance which may interfere with a grass catcher.

10.Check brakes and other mechanical parts for correct adjustment and wear. Replace worn or damaged parts promptly. Check the tightness of all nuts and bolts regularly. (For further details, see "PERIODIC SERVICE" and "ADJUSTMENT" section.)

11.Keep all shields and guards in place. Replace any that are damaged or missing. Do not operate unless they are functioning properly.

12.Before allowing other people to use your machine, explain how to operate and have them read this manual before operation.

13.Do not allow any bystanders around or near machine during operation.

14.Do not allow passengers, children or non-qualified operators on the machine at any time. The operator must remain in the machine seat throughout operation.

15.In addition to the design and configuration of equipment, hazard control and accident prevention are dependent upon the awareness, concern, and prudence of personnel involved in the operation, transport, maintenance of facilities.

16.Evaluate the terrain to determine what accessories and attachments are needed to properly and safely perform the job. Keep the machine and attachments in good operating condition and keep safety devices in place and in proper working condition. Do not operate unless they are functioning properly.

17.Do not modify the machine. Unauthorized modification may affect the function of the machine, which may result in personal injury.

18.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 manuals with equipment.

19.Keep your machine clean. Accumulations of dirt, grease, and trash can contribute to fires and lead to personal injury.

20.The exhaust gas from the muffler is very hot. To prevent fire, do not expose dry grass, mowed grass, oil and any other combustible materials to exhaust gas. Use a spark arrester where required. Also keep the engine and muffler clean all the time.

2. OPERATING

C Starting

1. Always sit in the operator's seat when starting engine or operating levers or controls.

2. Before starting the engine make sure that the motion control levers are in neutral lock, the parking brake is applied, and Power Take Off (PTO) is disengaged (OFF).

3. Do not start engine by shorting across starter terminals. The machine may start in gear and move if normal starting circuitry is bypassed.

4. Do not operate or idle engine in a non-ventilated area. Carbon monoxide gas is colorless, odorless, and deadly.

5. Do not start engine while tilting deck.

C Working

1. Do not turn sharply when driving at high speed.

2. To avoid tip over, slow down when turning on uneven terrain or before stopping.

3. Do not operate near ditches, holes, embankments, or other terrain, which may collapse under the machine weight. The risk of machine tip over increases when the ground is loose or wet.

4. Park the machine on a firm and level surface.

5. Watch where you are going at all times. Watch for and avoid obstacles. Be alert at curbs, shrubs, near trees, and other obstructions and hidden hazards. Obstacles can damage machine (fuel hoses, wire harness etc.).

6. Know what is behind you before backing up. Look to the rear before and when backing. Do not mow while in reverse unless absolutely necessary and make sure the area immediately behind you is clear of obstructions or holes and small children. Use extra caution when machine is equipped with Grass Catcher. Your view to the rear is restricted.

7. When working in groups, always let others know what you are doing ahead of time.

8. Do not drive machine on streets or highways. Watch for traffic when you cross roads or operate near roads.

9. Be aware of the mower discharge direction and do not point it at anyone. Never operate with the discharge deflector raised, removed or altered, unless using a grass catcher.

-3SAFE OPERATION

10.When using any attachments, never direct discharge material toward bystanders. Do not allow anyone and pets near the attachments while in operation. Do not mow when bystanders are present in the mowing area.

11.To reduce fire hazards, keep the engine exhaust area free of grass or leaves.

12.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.

13.Keep hands and feet away from the cutting units. Shut the engine off and wait for all movement to stop before removing grass catcher or unclogging chute.

14.Always inspect the mower for damage after striking a foreign object. Repair or replace any damaged parts before restarting.

15.Operate during daylight or in bright artificial light.

16.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.

17.Do not operate the machine when there is a possibility of lightning. Even if the machine is equipped with a cabin, the operator is not protected from lightning.

18.Never raise the deck with the blades running. Stop blades if not mowing.

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 must evaluate their ability to operate the machine safely enough to protect themselves and others from serious injury.

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. A Stopping distance increases with speed and weight of

towed load. Travel slowly and allow extra time and distance to stop.

A Never allow children or others in or on towed

equipment.

A Use additional caution when turning or operating

under adverse surface conditions.

ENGLISH

C Children

Tragic accidents can occur if the operator is not alert to the presence of children. Children are attracted to the machine and 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 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.

6. Use extra care when approaching blind corners, shrubs, trees, or other obstructions that might hide children from sight.

7. Do not mow in reverse unless it is absolutely necessary.

C Operation on slopes

Slopes are 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. If the engine stops when operating on a slope apply the parking brake immediately to prevent machine run away.

1. To avoid tip over, operate across the slopes not up and down. Stay off hills and slopes too steep for safe operation.

2. Remove obstacles such as rocks, tree limbs, etc.

SAFE OPERATION-4

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

ENGLISH

obstacles.

4. Follow the manufacturer's recommendations for wheel weight or counterweights to improve stability.

5. Keep all movement on the slopes slow and gradual. Do not make sudden changes in speed or direction. If tires lose traction, disengage PTO and proceed slowly straight down the slope.

6. Reduce speed and exercise extreme caution on slopes and in sharp turns to prevent tip-over or loss of control.

7. Use special caution when changing direction on slopes. Slow down, and use extra caution when changing direction on a slope.

DO NOT

1. Do not turn on slopes unless necessary. If necessary, turn uphill slowly and gradually.

2. Do not mow near drop-offs, ditches, or embankments. The mower could suddenly turn over if a wheel is over the edge of cliff or ditch, or if an edge caves in.

3. Do not mow on wet grass. Reduced traction could cause sliding and loss of control.

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 start or stop suddenly on slopes. If tires lose traction, disengage PTO and proceed slowly straight down the slope.

7. Never "freewheel". Do not let the machine travel downhill with motion control levers at neutral lock position or in neutral.

8. Do not operate machine without the mower deck installed.

C Stopping

1. Park the machine on level ground.

2. Make sure that the machine and all attachments have come to a complete stop before you get off.

3. Before you get off, apply parking brake, place the motion control levers in their neutral lock positions, disengage the PTO, lower all attachments to the ground, turn off the engine, and remove the key.

4. Do not park the machine on dry grass or leaves.

The speed of PTO: ZD1211 / ZD1211R / ZD1211L / ZD1211RL Without mower: 2450 to 2550 rpm at 3000 engine rpm

4. USING THE LIFT LINK

1. Use lift link only with authorized attachments designed for lift link usage.

5. TRANSPORTING

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. Use extra care when loading or unloading the machine into a trailer or truck. Use full width ramps for loading machine into trailer or truck.

4. This machine is not allowed to be used on public roads.

5. Shut off fuel while storing or transporting.

6. Tie the machine down securely using straps, chains, cable, or ropes.

7. Both front and rear straps should be directed down and outward from the machine.

6. SERVICING AND STORAGE

C Servicing

1. Before servicing, park the machine on a firm, level surface and apply the parking brake. Remove the key to prevent accidental start-up.

2. Allow the machine time to cool before touching the engine, muffler, radiator, etc.

3. Always stop the engine before refueling. Avoid spills and overfilling. Wipe up spilled fuel immediately.

3. USING THE PTO

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) Fuel tank cap

4. Use extra care in handling diesel fuels. They are flammable.

-5SAFE OPERATION

(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. Do not smoke when working around battery or when refueling. Extinguish all cigarettes, cigars, pipes, and other sources of ignition. Keep all sparks and flames away from battery and fuel tank.

7. Disconnect battery or remove spark plug wire before making any repairs. Disconnect the negative terminal first and the positive last. Reconnect positive first and negative last. Wear protective clothing and use insulated tools.

ENGLISH

Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before filling. Remove equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment with a portable container, rather than from a fuel dispenser nozzle. Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock open device. If fuel is spilled on clothing, change clothing immediately. Replace fuel cap and tighten securely. Charge batteries in an open well ventilated area, away from spark and flames. A battery, especially when charging, will give off hydrogen and oxygen gases, which can explode and cause serious personal injury. Unplug charger before connecting or disconnecting from battery.

6. Before "jump starting" a dead battery, read and follow all the instructions.

(1) Battery (2) Ground cable

(+): Positive terminal (-): Negative terminal

8. 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.

SAFE OPERATION-6

9. Keep first aid kit and fire extinguisher handy at all times.

ENGLISH

10.Do not remove the radiator cap while coolant is hot. When cool, slowly rotate cap to the first stop and allow sufficient time for excess pressure to escape before removing the cap completely. If the machine has a coolant recovery tank, add coolant there instead of the radiator.

11.Do not attempt to mount a tire on a rim unless qualified to do so and all proper safety precautions are followed. Never allow untrained personnel to service machine.

12.Always maintain the correct tire inflation pressure. Do not inflate tires above the recommended pressure shown in the Operator's Manual.

16.Fluid escaping from pinholes may be invisible. Use a piece of cardboard or wood to search for suspected leaks: do not use hands. Use safety goggles or other eye protection. If you get injured by escaping fluid, see a medical doctor at once. Serious infection or reaction will result if proper medical treatment is not administered immediately. This fluid can produce gangrene or severe allergic reaction.

13.Provide adequate support when changing wheels.

14.Make sure that wheel nuts and bolts have been tightened to the specified torque.

15.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

17.Keep hands and feet away from moving parts. If possible, do not make adjustments or repairs with the engine running.

18.Keep machine free of grass, leaves, or other debris build-up.

19.Do not change the engine governor setting or overspeed the engine.

20.Do not run a machine inside a closed area.

21.Mower blades are sharp and can cut your hands. Wrap the blade(s) or wear gloves, and use extra caution when servicing them. Never straighten or weld blades.

22.Keep nuts and bolts, especially blade attachment bolts, tight and keep equipment in good condition.

23.Never tamper with safety devices. Check their operation for proper function regularly.

24.Waste products such as used oil, fuel, coolant, brake fluid, and batteries, can harm the environment, people, pets and wildlife. Please dispose of properly.

25.Do not use beverage containers for waste fluids or other products. Someone, particularly children, may drink them by mistake.

26.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.

27.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.

OPERATING THE ENGINE18

ENGLISH

WARMING UP

To avoid serious injury or death: A Be sure to apply the parking brake during

warm-up.

For 5 minutes after engine start-up, allow the 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, the problems such as seizure, breakage or premature wear may develop.

(1) Fuel valve

COLD WEATHER STARTING

When the ambient temperature is below -5 (23 ) and the engine is very cold. (If the engine fails to start after 10 seconds, turn off the key for 30 seconds. Then repeat steps 7 and 8 in "STARTING THE ENGINE". To protect the battery and the starter, make sure that the starter is not continuously turned for more than 10 seconds.)

BWarm-up and Transmission Oil in the Low

Temperature Range

Hydraulic oil serves as transmission oil. 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 or 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:

Ambient temperature Warm-up time requirement

Higher than 0 (32 ) Approx. 5 minutes

-10 to 0 (14 to 32 ) 5 to 10 minutes

-20 to -10 (-4 to 14 ) 10 to 15 minutes

Below -20 (-4 ) More than 15 minutes

A Do not operate unless the engine is 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.

19OPERATING THE ENGINE

JUMP STARTING

To avoid serious injury or death: A Keep cigarettes, sparks, and flames away from

battery.

A If the machine battery is frozen, do not jump

start the engine.

A Do not connect the other end of negative

jumper cable to the negative terminal of the machine battery.

When jump starting the engine, follow the instructions below to start the engine safely.

1. Bring a 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 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 the 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)

A Use of a higher voltage source on a machine could

result in severe damage to the machine electrical system. Use only matching voltage source when "jumpstarting" a low or dead battery condition.

ENGLISH

20 OPERATING THE MACHINE

OPERATING THE MACHINE

ENGLISH

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 "broken-in" and are not accustomed to each other, so care must 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 must 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 must 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.)

BEngine Break-in

After the first 50 hours of operation, change the engine oil and filter. (See "EVERY 200 HOURS" in "MAINTENANCE" section.)

BMachine Break-in

After the first 400 hours of operation, change the transmission fluid. (See "EVERY 400 HOURS" in "MAINTENANCE" section.) After the first 50 hours of operation, change the oil filter. (See "EVERY 200 HOURS" "EVERY 400 HOURS" in "MAINTENANCE" section.)

To avoid serious injury or death: A Do not operate the mower without the deflector

shield in the down position.

To avoid serious injury or death: A The machine relies upon the engine driven

transmission for speed, direction and steering control. If the engine is not running, the machine cannot be driven or controlled. If the engine stops when operating on a slope,

apply the parking brake immediately to prevent machine runaway.

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 When turning the machine, be sure to reduce

the travel speed and operate motion control levers carefully.

A To avoid tip over, operate across slopes, not up

and down. Avoid sudden starts and stops on slopes. Slow down, and use extra caution when changing direction on a slope. Park the machine on a firm and 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 mow near drop-offs, ditches or

embankments. The mower could turn over if a wheel is over the edge of cliff or ditch, or if an edge caves in.

A Do not drive 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 machine is equipped with Grass Catcher.

To avoid serious injury or death: 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. Discharged 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.

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.

A Be sure to disengage the PTO and sit on the

operator's seat before starting the engine.

ADJUSTING CUTTING HEIGHT

To avoid serious injury or death: A Do not engage the mower in the transport

position.

1. Before adjusting cutting height, check that all tire pressures are correct. If necessary adjust to the correct tire pressure.

2. To set the cutting height, start engine and depress the hydraulic lift control pedal (UP) to raise mower deck to the top position. Adjust the cutting height control dial to desired height. Lower the mower deck by depressing the hydraulic lift control pedal (DOWN). Then the mower deck will be set to the cutting height.

3. Use the higher settings for mowing in a rough area or when mowing tall grass. Lower settings must be used only for smooth lawns where short grass is desired.

31OPERATING THE MOWER

ENGLISH

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 must 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 1/3 of the height of the grass or a maximum of 25 mm (1 in.) in 1 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 must be cut in the afternoon or evening when it is free of moisture.

To avoid serious injury or death: 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.

(1) Cutting height control dial (2) Hydraulic lift control pedal

4. Lower the mower deck by depressing the hydraulic lift control pedal (DOWN). This lowers the mower deck from the "TRANSPORT" position to the "OPERATING" position.

To avoid serious injury or death: A Always stop the engine and remove the key

before checking oil.

1. Check engine oil before starting and 5 minutes or more after the engine has stopped.

2. Wipe dipstick area clean.

3. To check the oil level, remove the dipstick, wipe it clean, replace it, and draw it out again. Check to see that the oil level is between the 2 notches.

4. Add new oil to the prescribed level at the oil port if necessary.

(1) Engine oil port (2) Oil level dipstick

(A) "UPPER LEVEL" (B) "LOWER LEVEL"

ENGLISH

To avoid serious injury or death: A Handle fuel carefully. If the engine is running,

do not fill the fuel tank. If engine is hot, let engine cool several minutes before adding fuel. Do not smoke while filling the fuel tank or servicing the fuel system. Fill fuel tank only to bottom of filler neck.

Check the fuel level. Take care that the fuel tank does not become empty.

Fuel tank capacity 49 L (12.9 U.S.gals.)

5. When using a different brand or viscosity oil from the previous one, remove all of the old oil and oil filter. Never mix 2 different types of oil.

6. Use the proper Engine Oil SAE according to the ambient temperatures. (See "LUBRICANTS, FUEL AND COOLANT" in "PERIODIC SERVICE" section.)

A Use Diesel Fuel Only

1. Use No.2 diesel fuel.

2. Use No.1 diesel fuel if the temperature is below

-10 (14 ).

3. Always use a strainer when refueling to prevent fuel injection pump contamination.

A Do not permit dirt or trash or water to get into the fuel

system.

A Be careful not to let the fuel tank become empty,

otherwise air will enter the fuel system, necessitating bleeding before next engine start.

A Be careful not to spill fuel during refueling. If a spill

should occur, wipe it off at once, or it may cause a fire.

A To prevent condensation (water accumulation) in the

fuel tank, fill the tank before parking overnight.

A When refueling, basically fill both fuel tanks full. A In the case you have a small amount of fuel, if fuel is

still in the fuel tank RH, fill the fuel tank LH first.

A The fuel gauge shows the fuel level of fuel tank RH.

When the fuel gauge flashes, fill fuel as soon as possible.

A When the fuel gauge flashes, do not fill fuel on a slope.

Fuel can absorb air and the engine can stall.

PERIODIC SERVICE48

A If the engine stalled with some remaining in the fuel

tank RH, close the fuel valve of fuel tank LH and you can operate.

BChecking Coolant Level

BChecking Transmission Fluid Level

To avoid serious injury or death: A Allow the transmission case to cool down

sufficiently when cleaning its surface.

1. Park the machine on a flat surface, lower the implement to the ground and shut off the engine and remove the key. Allow the machine to idle for 1-3 minutes, and then check fluid.

2. Raise and lock the operator's seat.

3. To check the oil level, draw out the dipstick, wipe it clean, replace it, and draw it out again. Check to see that the oil level lies between the two notches. If the level is too low, add the new oil to the prescribed level at the oil inlet. (See "LUBRICANTS, FUEL AND COOLANT" in "PERIODIC SERVICE" section.)

To avoid serious injury or death: A Do not remove the radiator cap when the

engine is hot. Then loosen cap slightly to the stop to relieve any excess pressure before removing cap completely.

Check the coolant level daily for both the radiator and the recovery tank before starting engine.

1. Remove the radiator cap and check to see that the coolant level is just below the fill port.

2. Check to see that the coolant level is between the "FULL" and "LOW" marks of recovery tank.

3. When the coolant level drops due to evaporation, add water only up to just below the fill port of the radiator and the full level of the recovery tank. In case of leakage, add anti-freeze and water in the specified mixing ratio up to the full level. (See "Flushing Cooling System and Changing Coolant" in "EVERY 2000 HOURS or EVERY 2 YEARS" in "MAINTENANCE" section.)

4. Check radiator hoses for wear, cracks, bubbles or leaks. If any such are found, repair immediately. (See "Replacing Radiator Hose" in "EVERY 4 YEARS" in "MAINTENANCE" section.)

5. Set the direction of the recovery tank cap outlet at left front (45 ). Set the bottom tip of the hose between front side of radiator hose and inner side of the frame. (This will prevent the hose from pulling down and open the recovery tank cap.)

BChecking Battery Condition

ENGLISH

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.

A For parking brake test purposes, only use 17 ramp.

BGreasing

To avoid serious injury or death: A Be sure to stop the engine and remove the key

before greasing.

Grease the following location. If you operated the machine in extremely wet and muddy conditions, lubricate grease fittings more often.

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 or death: A Batteries, battery posts, terminals and related

accessories contain lead and lead compounds, and other chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. WASH HANDS AFTER HANDLING.

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 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.

(1) Front mower link bushing (2 places) (2) Rear mower link bushing (4 places) (3) Front mower link (4) Rear mower link

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 a new one, use

battery of equal specification in table below.

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 4.5 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 machine for a long period, remove the battery from machine, adjust the electrolyte to the proper level and store in a dry place out of direct sunlight.

2. The battery self-discharges while it is stored. Recharge it once every 3 months in hot seasons and once every 6 months in cold seasons.

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 or death: 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.
