SAFE OPERATION -1

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.

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.

(2)Seat belt

ENGLISH

-2 SAFE OPERATION

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 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.

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.

SAFE OPERATION -3

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 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 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.

AStopping 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.

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.

DO

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.

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.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.

ENGLISH

ENGLISH

-4 SAFE OPERATION

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.

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.

The speed of PTO:

ZD1011 / ZD1021 Without mower: 2450 to 2550 rpm at 3200 engine rpm

4.USING THE LIFT LINK

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

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.

(1)Fuel tank cap

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

(1)Use only an approved container.

(2)Do not remove fuel cap or refuel with the engine running. Allow engine to cool before refueling. Do not smoke while refueling or when standing near fuel.

(3)Do not refuel the machine indoors and always clean up spilled fuel or oil.

(4)Do not store the machine or fuel container inside where there is an open flame, such as in a water heater.

SAFE OPERATION -5

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.

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.

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.

(1) Battery	(+): Positive terminal
(2) Ground cable	(-): 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.

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

-6 SAFE OPERATION

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.

C Storage

1.Keep the machine and supply of fuel in locked storage and remove the ignition key to prevent children or others from playing or tampering with them.

2.To avoid sparks from an accidental short circuit, always disconnect the battery's ground cable (-) first and reconnect it last.

(1)	Battery	(+): Positive terminal
