ENGLISH

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. 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")

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 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.

19.Follow the maintenance recommendations. See "MAINTENANCE ".

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 bypassing 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.

1. BEFORE OPERATING

2. OPERATING

SAFE OPERATION-2

ENGLISH

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.Shut the engine off and wait for all movement to stop before removing grass catcher or unclogging chute.

11.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.

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 after striking any foreign object. This will insure that all mower 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 either the entire grass catcher or the guard 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.Stop the blades rotating before crossing surface other than grass.

18.Never leave a running machine unattended. Always turn off blades, set parking brake, stop engine, and remove the key before dismounting.

19.Be extremely alert for all other traffic when operating the mower and grass catcher near public roads or highways.

20.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.

21.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.

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.

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 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.

9. If 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.

-3SAFE OPERATION

ENGLISH

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 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 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.

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 safety 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.

BBallast

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.

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 tip-over. The Attachment's Manual shows how much rear ballast is required for your application. Rear ballast is available from your KUBOTA Dealer.

WARMING UP

To avoid personal injury: A Be sure to set 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.

ENGLISH

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 low-

sulfur 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).

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.

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).

BBattery Condition

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 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 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.

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.

(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.)

C Battery Charging

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.

The factory-installed battery is of non-refillable type. If the battery is weak, charge the battery or replace it with new one.

Always use a 50/50 mix of long-life coolant and clean soft water in KUBOTA engines. Consult your local KUBOTA dealer concerning coolant for extreme conditions.

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 Premix 50% LLC with 50% clean soft water. 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.

A When mixing the anti-freeze with water, the anti-freeze

mixing ratio is 50%.

* At 1.013 x 10 Pa (760 mmHg) pressure (atmospheric).

A higher boiling point is obtained by using a radiator pressure cap which permits the development of pressure within the cooling system.

5. Adding the LLC (1) Add only water if the coolant level reduces in the

cooling system by evaporation.

(2) If there is a mixture leak, add the LLC of the same

manufacturer and type in the mixing ratio 50%.

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.

46 STORAGE

ENGLISH

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 2 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 2 months in cold seasons.

7. Drain fuel tank, fuel lines.

8. Store the machine where it is dry and sheltered from rain. Cover the machine with a tarpaulin.

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".)

4. Check all fluid levels. (engine oil, hydrostatic oil)

5. Start the engine. Shut the engine off and walk around 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.
