SAFE OPERATION
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 and understand 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 understand the contents, it is the owner's responsibility to explain this material to them. This mowing machine is capable of amputating hands, feet and throwing objects. Failure to observe the following safety instructions could result in serious injury or death.
BEFORE OPERATING THE MACHINE
Know your equipment and its limitations. Read all instructions in this manual before attempting to start and operate the machine.
1. General
· 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 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 operator's manual before operating the machine. Practice operating the machine at low engine speed in an unobstructed area without engaging the mower.
· Pay special attention to the safety labels on the machine itself.
· Do not operate the machine or any attachments while under the influence of alcohol, medication, controlled substances or when fatigued.
· Do not wear loose, torn, or bulky clothing around the machine. The clothing may catch on moving parts or controls, leading to the risk of an accident. Wear and use any additional safety items such as a hard hat, safety boots or shoes, eye and hearing protection, gloves and so on, as appropriate or required.
· Do not wear radio or music headphones while operating the machine.
ZD1211,ZD1221
· Do not operate the machine or any attachments while using or texting with a cellphone or any other electronic device. Safe operation requires your full attention.
· Carefully check the vicinity before operating machine or any implement attached to it. Clear the work area of objects (such as wires and rocks,) that might be picked up and thrown. Check for overhead clearance which may interfere with a grass catcher.
· Check parking brake and other mechanical parts for correct adjustment and wear. Replace worn or damaged parts promptly. Check the tightness of all nuts and bolts regularly. (See PERIODIC SERVICE on page 52 and ADJUSTMENT on page 87.)
· Keep all shields and guards in place. Replace any that are damaged or missing. Do not operate unless they are functioning properly.
· Before allowing other people to use your machine, explain how to operate and have them read this manual before operation.
· Do not allow any bystanders around or near machine during operation.
· 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.
· 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 the equipment.
· 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.
· Do not modify the machine. Unauthorized modification may affect the function of the machine, which may result in personal injury.
· Use only implements approved by KUBOTA. Use proper ballast on the front or rear of the machine to reduce the risk of upsets. Follow the safe operating procedures specified in the manuals of the equipment.
· Keep your machine clean. Accumulations of dirt, grease, and trash can contribute to fires and lead to personal injury.
· The exhaust gas from the muffler is very hot. To prevent fire, do not expose dry grass, mowed
5
SAFE OPERATION
grass, oil and any other combustible materials to the exhaust gas. Use a spark arrester where required. Keep the engine and muffler clean all the times.
2. ROPS
· The ROPS is an integral and effective safety device.
· KUBOTA recommends the use of a roll-over protective structure (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 foldable ROPS in areas where there are slopes, drop-offs or water. · Check carefully for overhead clearances (such as branches, doorways and electrical wires) before driving under any objects and do not contact them. · Keep the ROPS in safe operating condition by periodically and thoroughly inspecting for damage and keeping all mounting fasteners tight. · 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.
(1) ROPS (2) Seat belt
OPERATING THE MACHINE
1. Starting to operate the machine
· Always sit in the operator's seat when starting the engine or operating levers or controls.
· Before starting the engine make sure that the motion control levers are in "NEUTRAL LOCK", the parking brake is applied, and the power take-off (PTO) is disengaged (OFF).
· Do not start the engine by shorting across starter terminals. The machine may start in gear and move if the normal starting circuitry is bypassed.
· Do not operate or idle the engine in a nonventilated area. Carbon monoxide gas is colorless, odorless, and deadly.
· Do not start the engine while tilting deck. · Do not start the engine when the front or rear tires
are not on the ground. · Check before each use that the operator presence
control (OPC) system is functioning correctly. Test the safety systems. (See Checking the engine start system on page 66 and Checking the OPC system on page 66.) Do not operate unless they are functioning correctly. · Check all fluids before starting.
2. Working the machine
· Do not turn sharply when driving at high speed. · To avoid tip-over accidents, slow down when
turning on uneven terrain or before stopping. · Do not operate near ditches, holes, embankments,
or other terrain, which may collapse under the machine's weight. The risk of machine tip-overs increases when the ground is loose or wet. · Park the machine on a firm and level surface. Before you get off, apply the parking brake, place the motion control levers in their neutral lock positions, disengage the PTO, lower all
6
ZD1211,ZD1221
attachments to the ground, turn off the engine, and remove the key. · 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.). · Know what is behind you before backing up. Look to the rear before and when backing. Do not mow while in reverse. Operate in reverse with the blades engaged only when 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. · When working in groups, always let others know what you are doing ahead of time. · Do not drive the machine on streets or highways. Watch for traffic when you cross roads or operate near roads. · 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. · When using any attachments, never direct discharge material toward bystanders. Do not allow people or pets near the attachments while in operation. Do not mow when bystanders are present in the mowing area. · To reduce fire hazards, keep the engine exhaust area free of grass or leaves. · Be sure that the rotating blades and the engine are stopped and the key is removed before placing hands or feet near blades, cleaning blockages or unclogging the discharge deflector. · 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 discharge deflector. · Always inspect the mower for damage after striking a foreign object. Repair or replace any damaged parts before restarting. · Operate during daylight or in bright artificial light. · 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. · 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. · Never raise the deck with the blades running. Disengage the PTO and stop the blades from rotating if not mowing.
SAFE OPERATION
3. Safety for children
Tragic accidents can occur if the operator is not alert of the presence of children. Children are attracted to the machine and mowing activity. · Never assume that children will remain where you
last saw them. · Keep children out of the mowing area and under
the watchful care of another responsible adult. · Be alert and turn the machine off if children enter
the area. · Before and when backing, look behind and down
for small children. · Never carry children. They may fall off and be
seriously injured or interfere with safe machine operation. · Never allow children to operate the machine, even under adult supervision. Local regulation can restrict the age of the operator. · Use extra care when approaching blind corners, shrubs, trees, or other obstructions that might hide children from sight. · Do not mow in reverse. Operate in reverse with the blades engaged only when it is absolutely necessary and make sure that the area to the rear is clear of children before doing so.
4. Operators, age 60 years and older
Data indicates that operators, age 60 years and older, 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.
5. Operating on slopes
Slopes are a major factor related to loss-of-control and tip-over 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 runaway.
ZD1211,ZD1221
7
SAFE OPERATION
Do · To avoid tip-over accidents, operate across slopes,
not up and down. Stay off hills and slopes too steep for safe operation. · Remove obstacles such as rocks and tree limbs, etc. · 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. · Follow the manufacturer's recommendations for wheel weight or counterweights to improve stability. · Keep all movement on slopes slow and gradual. Do not make sudden changes in speed or direction. · Avoid starting or stopping on a slope. If tires lose traction, disengage the PTO and proceed slowly straight down the slope. · Reduce the speed and exercise extreme caution on slopes and in sharp turns to prevent tip-over accidents or loss of control. · Use special caution when changing direction on slopes. Slow down, and use extra caution when changing direction on a slope. Do not · Do not turn on slopes unless necessary. If necessary, turn uphill slowly and gradually. · 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. · Do not mow on wet grass. Reduced traction could cause sliding and loss of control. · Do not try to stabilize the machine by putting your foot on the ground. · Do not use grass catcher on steep slopes. · Do not start or stop suddenly on slopes. If tires lose traction, disengage the PTO and proceed slowly straight down the slope. · Never "freewheel". Do not let the machine travel downhill with motion control levers at the "NEUTRAL LOCK" position or in "NEUTRAL". · Do not operate the machine without the mower deck installed.
8
6. Stopping the machine
· Park the machine on level ground. · Make sure that the machine and all attachments
have come to a complete stop before you get off. · Before you get off, apply the 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. · Do not park the machine on dry grass or leaves.
7. Using the PTO
· Before installing or using PTO-driven equipment, read the manufacturer's manual and review the safety labels attached to the equipment.
· Wait until all moving components have completely stopped before connecting, disconnecting, adjusting, cleaning, or servicing any PTO-driven equipment.
· Use the PTO with KUBOTA approved attachments. The speed of PTO: ZD1211-AU, ZD1221R-AU, ZD1221L-AU, ZD1221RLAU without mower: 2450 to 2550 rpm at 3000 engine rpm
8. Using the lift link
· Use lift link only with authorized attachments designed for lift link usage.
TRANSPORTING THE MACHINE
· Disengage power to attachment(s) when transporting or not in use.
· Do not tow this machine. Use a suitable truck or trailer when transporting on public roads.
· Use extra care when loading or unloading the machine into a trailer or truck. Use full width ramps for loading machine into a trailer or truck.
· This machine is not allowed to be used on public roads.
· Shut off fuel while storing or transporting. · Tie the machine down securely using straps,

1. Servicing the machine
· Before servicing, park the machine on a firm, level surface and apply the parking brake. Remove the key to prevent an accidental start-up.
· Allow the machine time to cool before touching the engine, muffler, radiator and so on.
ZD1211,ZD1221
· Always stop the engine before refueling. Avoid spills and overfilling. If fuel is spilled, do not attempt to start the engine and avoid creating any source of ignition until fuel vapors have dissipated.
(1) Fuel tank cap
· Use extra care when handling diesel fuels. They are flammable. 1. Use only an approved container. 2. Do not remove the fuel cap or refuel with the engine running. Allow the 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.
· 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.
SAFE OPERATION
container opening at all times until fueling is complete. Do not use a nozzle lock open device. · If fuel is spilled on clothing, change the clothing immediately. Replace the 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 the charger before connecting or disconnecting from battery. · Before "jump starting" a dead battery, read and observe all of the instructions: · Disconnect the battery or remove the spark plug wire before making any repairs. Disconnect the negative terminal first and the positive last. Reconnect the positive first and negative last. Wear protective clothing and use insulated tools.
· 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

· 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
· Keep a first aid kit and fire extinguisher handy at all times.
· 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.
· 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 the machine.
· Always maintain the correct tire inflation pressure. Do not inflate tires above the recommended pressure shown in the operator's manual.
· 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.
· Provide adequate support when changing wheels. · Make sure that wheel nuts and bolts have been
tightened to the specified torque. · 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
· Keep hands and feet away from moving parts. If possible, do not make adjustments or repairs with the engine running.
· Keep the machine free of grass, leaves, or other debris build-up.
· Do not change the engine governor setting or overspeed the engine.
· Do not run the machine inside a closed area. · 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. · Keep nuts and bolts, especially blade attachment bolts, tight and keep equipment in good condition. · Never tamper with safety devices. Check their operation for proper function regularly. · Waste products such as used oil, fuel, coolant, brake fluid, and batteries can harm the
10
ZD1211,ZD1221
environment, people, pets and wildlife. Please dispose of the waste products properly. · Do not use beverage containers for waste fluids or other products. Someone, particularly children, may drink them by mistake. · Securely support the machine or any machine elements with stands or suitable blocking before working underneath. For your safety, do not rely on hydraulically supported devices as they may leak down, suddenly drop or be accidently lowered. · Consult your local recycling center or KUBOTA Dealer to learn how to recycle or get rid of waste products. 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.
2. Storage
· 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.
· To avoid sparks from an accidental short circuit, always disconnect the battery's ground cable (-) first and reconnect it last.
SAFE OPERATION

· To avoid the danger of exhaust fume poisoning, do not operate the engine indoors without adequate ventilation.
· To reduce fire hazards, clean the machine thoroughly before storage. Dry grass and leaves around the engine and muffler may ignite.
· Let the engine cool before storing and do not store near flames.
· Shut off fuel while storing or transporting.

COLD WEATHER STARTING
· When the ambient temperature is below -5 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. Details regarding steps 7 and 8 can be found in a different section. (See STARTING THE ENGINE on page 27.)
· To protect the battery and the starter, make sure not to turn the starter continuously for more than 10 seconds.
WARMING UP THE ENGINE
WARNING
To avoid serious injury or death:
ZD1211,ZD1221
WARMING UP THE ENGINE
· Be sure to apply the parking brake during warm-up.
For 5 minutes after the engine start-up, allow the engine to warm up without applying any load. This is to allow oil to reach every part of the engine. If load is applied to the engine without this warm-up period, problems such as seizure, breakage or premature wear may appear.
1. Warm-up and transmission oil in the low temperature range
Hydraulic oil serves as transmission oil. In cold weather conditions, the oil may be cold with increased viscosity. This can cause delayed oil circulation or abnormally low hydraulic pressure for some time after engine startup. This, in turn, result in trouble in the hydraulic system or damage to the hydraulic clutch. To prevent this from happening warm up the engine at about 50% of rated rpm according to the following table.
Ambient temperature Higher than 0 (32 ) -10 to 0 (14 to 32 ) -20 to -10 (-4 to 14 )
Below -20 (-4 )
Warm-up time requirement Approximately 5 minutes 5 to 10 minutes 10 to 15 minutes More than 15 minutes
IMPORTANT : · Do not operate unless the engine is well
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. · 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.
JUMP STARTING
WARNING
To avoid serious injury or death: · Keep cigarettes, sparks, and flames away from
the battery. · If the machine battery is frozen, do not jump
start the engine. · Do not connect the other end of the negative
jumper cable to the negative terminal of the machine battery.
OPERATING THE ENGINE
When jump starting the engine, observe the following instructions 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.
IMPORTANT : · The vehicles must not touch.
2. Apply the parking brakes of both vehicles and put the shift levers in the neutral position. Shut the engine off.
3. Put on safety goggles and rubber gloves. 4. Ensure that 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).
Connect cables in numerical order. Disconnect in reverse order after use.
(1) Dead battery (2) Jumper cables (3) Engine block or frame
(4) Helper battery
IMPORTANT : · This machine has a 12 volt negative (-)
ground starting system. · Use only same voltage for jump starting. · Use of a higher voltage source on the
machine could result in severe damage to the machine electrical system. Use only a matching voltage source when "jump starting" a low or dead battery.

OPERATING THE MACHINE
OPERATING A NEW MACHINE
How a new machine is operated and maintained will determine the operating life of the machine. A new machine just off the factory production line has been tested, but the various parts are not "broken-in" and 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 "breakingin" period greatly affects the life of your machine. Therefore, to obtain the maximum performance and the longest operating 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.
1. Changing lubricating oil for new machine
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 it would ordinarily be required. For further details of change interval hours. (See SERVICE INTERVALS on page 63.)
2. Engine break-in
After the first 50 hours of operation, change the engine oil and filter. (See EVERY 200 HOURS on page 76.)
3. Machine break-in
After the first 400 hours of operation, change the transmission fluid. (See EVERY 400 HOURS on page 77.) After the first 50 hours of operation, change the oil filter. (See EVERY 200 HOURS on page 76 and EVERY 400 HOURS on page 77.)
DANGER
To avoid serious injury or death: · Do not operate the mower without the discharge
deflector in the "DOWN" position.
WARNING
To avoid serious injury or death: · 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 a machine runaway. · Do not allow anyone other than the driver to ride on the machine. · 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. · When making a turn, be sure to reduce the travel speed and operate the motion control levers carefully. · To avoid tip-over accidents, 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. · 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. · Do not mow near drop-offs, ditches or embankments. The mower could turn over if a wheel is over the edge of a cliff or ditch, or if an edge caves in. · Do not drive the machine on streets or highways. Watch for traffic when you cross roads or operate near roads. · 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. · Keep bystanders, especially children, and animals away from the mowing area. · Clear the work area of objects which might be picked up and thrown by the blades. · Do not direct the opening of the discharge deflector at bystanders or animals. Discharged objects may cause injury. Plan your mowing carefully before starting operation. · Keep bystanders especially children and animals away from the mowing area.

MOWING TIPS
WARNING
To avoid serious injury or death: · Clear the work area of objects which might be
picked up and thrown by the blades. · Keep bystanders and animals away from the
mowing area. · Be sure to disengage the PTO and sit on the
operator's seat before starting the engine.
1. When using the 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 and so on, 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 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. For a healthy lawn, only 1/3 of the grass plant should be removed in 1 mowing. For example, tall grass with the height of 75 mm (3 in.) can be cut to a minimum of 50 mm (2 in.).
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 25 mm (1 in.). 5. Clippings may be left on the lawn unless they form clumps or rows.
(A) H/G>2/3 (G) Before mowing (H) Best cut grass height: 50 to 80 mm
6. For best appearance, grass must be cut in the afternoon or evening when it is free of moisture.
ADJUSTING THE CUTTING HEIGHT
DANGER
To avoid serious injury or death: · Do not engage the mower in the "TRANSPORT"
position. The cutting height control dial can adjust the cutting height from 25 mm (1 in.) to 122 mm (5 in.) with 6 mm (0.25 in.) step. 1. Before adjusting the 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.

1. Checking the engine oil level
WARNING
To avoid serious injury or death: · Always stop the engine and remove the key
before checking the oil.
1. Check the engine oil before starting and 5 minutes or more after the engine has stopped.
2. Wipe the 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"
IMPORTANT : · When using a different brand or viscosity oil
from the previous one, remove all of the old oil and the oil filter. Never mix 2 different types of oil. · Use the proper SAE engine oil according to the ambient temperature. (See LUBRICANTS, FUEL AND COOLANT on page 57.)
2. Checking the amount of fuel and refueling
WARNING
To avoid serious injury or death: · Handle the fuel carefully. If the engine is
running, do not fill the fuel tank. If the engine is hot, let the engine cool down several minutes before adding fuel. · Do not smoke while filling the fuel tank or servicing the fuel system. Fill the fuel tank only to the bottom of the filler neck.
PERIODIC SERVICE
Check the fuel level. Take care that the fuel tank does not become empty.
Fuel tank capacity
49 L (12.9 U.S.gals.)
IMPORTANT : · 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.
IMPORTANT : · Do not permit dirt or trash or water to get into
the fuel system. · Be careful not to empty the fuel tank otherwise
air will enter the fuel system, necessitating bleeding before next engine start. · Be careful not to spill fuel during refueling. If a spill should occur, wipe it off at once, or it may cause a fire. · To prevent condensation (water accumulation) in the fuel tank, fill the tank before parking overnight. · When refueling, basically fill both fuel tanks full. · 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. · The fuel gauge shows the fuel level of fuel tank RH. When the fuel gauge flashes, fill fuel as soon as possible. · When the fuel gauge flashes, do not fill fuel on a slope. Fuel can absorb air and the engine can stall. · If the engine stalled with some remaining in the fuel tank RH, close the fuel valve of fuel tank LH and you can operate.

3. Checking transmission fluid level
WARNING
To avoid serious injury or death: · 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 to 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 2 notches. If the level is too low, add the new oil to the prescribed level at the oil inlet. (See LUBRICANTS, FUEL AND COOLANT on page 57.)
LUBRICANTS, FUEL AND COOLANT
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 antifreeze and water in the specified mixing ratio up to the full level. (See Flushing cooling system and changing coolant on page 80.)
4. Check radiator hoses for wear, cracks, bubbles or leaks. If any such are found, repair immediately. (See Replacing radiator hose on page 83.)
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.)

DANGER
To avoid the possibility of battery explosion: For the refillable type battery, follow these instructions: · 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. · 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.
WARNING
To avoid serious injury or death: · Batteries, battery posts, terminals and related
accessories contain lead, 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. · Never remove the battery cap while the engine is running. · Keep electrolyte away from eyes, hands and clothes. If you are spattered with electrolyte, wash it away completely with water immediately and get medical attention. · Wear eye protection and rubber gloves when working around the battery.
MAINTENANCE
NOTE : · The factory-installed battery is a non-refillable
type. If the battery is weak, charge the battery or replace it with a new one.
IMPORTANT : · 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. · When exchanging an old battery with a new one, use a battery of equal specifications (as described in the following table).

· If someone drank antifreeze, seek immediate medical help. Do not make the person throw up unless you are told to do so by poison control or a health care professional. Use standard first aid and CPR for signs of shock or cardiac arrest. Call your local poison control center or your local emergency number for further assistance.
· When antifreeze comes in contact with the skin or clothing, wash it off immediately.
· Do not mix different types of antifreeze. The mixture can produce chemical reaction causing harmful substances.
· Antifreeze is extremely flammable and explosive under certain conditions. Keep fire and children away from antifreeze.
· When draining fluids from the engine, place some container underneath the engine body.
· Do not pour waste onto the ground, down a drain, or into any water source.
(1) Drain valve
IMPORTANT : · Do not start engine without coolant. · Start engine with the hood closed. · Use clean, distilled water and antifreeze to
fill the radiator and recovery tank. · When the antifreeze is mixed with water, the
antifreeze mixing ratio must be less than 50%. · Securely tighten radiator cap. If the cap is loose or improperly fitted, water may leak out and the engine could overheat.
2. Antifreeze
WARNING
To avoid serious injury or death: · When using antifreeze, put on some protection
such as rubber gloves. (Antifreeze contains poison.)
ZD1211,ZD1221
· Also, observe the relevant environmental protection regulations when disposing of antifreeze.
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.
81
MAINTENANCE
4. The procedure for the mixing of water and antifreeze differs according to the make of the antifreeze and the ambient temperature. Refer to SAE J1034 standard, more specifically also to SAE J814c.
IMPORTANT : · When mixing the antifreeze with water, the
antifreeze mixing ratio is 50%.

* At 1.013 x 105 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 a. Add only water if the coolant level reduces in the cooling system by evaporation. b. If there is a mixture leak, add the LLC of the same manufacturer and type in the mixing ratio 50%.
IMPORTANT : · Never add any long-life coolant of
different manufacturer. (Different brands may have different additive components, and the engine may fail to perform as specified.)
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 2000 hours or every 2 years whichever comes faster.
NOTE : · The above data represent industry
standards that necessitate a minimum glycol content in the concentrated antifreeze.
