Be alert. Operating this tractor when you are tired, ill or under the in- fluence of alcohol or drugs may result in serious injury.
Keep all persons and pets away from the operating area.
Child Safety
Serious injury or death can occur if a child falls off the tractor or runs into the tractor’s path and is run over by the machine. l
Allowing children to ride as passengers on the tractor can be l dangerous.
Keep children indoors and supervised at all times when any outdoor power equipment is being used nearby. Young children move quickly and are attracted to the tractor and the operating activity especially if l they have been given rides before.
Never assume that children will remain where you last saw them. Be alert, and turn the machine off if children enter the area. Use extreme l care when backing up, and when approaching corners, shrubs, trees, and other obstructions that might hide children from sight.
Children should never be allowed to operate the tractor, even under adult supervision.
Fire and Burn Hazard
. Gasoline is extremely flammable, and gasoline vapor can explode.
Use extreme care when handling gasoline. Keep gasoline out of reach of children. l l
Refuel in a well ventilated area with the engine stopped.
Allowed the engine to cool before refueling. Fuel vapor or spilled fuel may ignite. l The accumulation of dry grass and leaves around the engine, the ex- haust system, or on top of the cutter deck (especially around the l pulleys) may ignite.
It is illegal in some areas to operate an engine without a USDA qualified spark arrester. Periodic maintenance is required to keep it functioning as designed.
The engine and exhaust system become very hot during operation and re- main hot for a while after stopping. Contact with hot engine components can cause burn injuries and can ignite some materials. l l
Avoid touching a hot engine or exhaust system.
Allow the engine to cool before performing maintenance or storing the tractor indoors.
Carbon Monoxide Poisoning Hazard
Exhaust contains poisonous carbon monoxide, a colorless and odorless gas. Breathing exhaust can cause loss of consciousness and may lead to death. l If you run the engine in an area that is confined, or even partially enclos- ed, the air you breathe could contain a dangerous amount of exhaust gas. To keep exhaust gas from building up, provide adequate venti- lation.
Blade Hazard
The cutting blades are sharp, and they turn at high speed. Accidental con- tact can cause serious injury. l l l
Keep your hands and feet away from the mower deck while the engine is running.
Stop the engine, disengage the Power Take Off (P.T.O.) clutch and remove the key before inspection or maintenance of the deck or blades.
Disconnect the spark plug caps to prevent any possibility of accidental starting. Wear heavy gloves to protect your hands from the blades when cleaning out the mower deck, or when inspecting or replacing the blades.
5
Thrown Object Hazard
Objects hit by the blades can be thrown from the tractor with great force, . and may cause serious injury. l
Before mowing, clear the mowing area of sticks, stones, dog bones, l l and other litter and loose objects. Mow only in daylight, or in well-lit areas at night, so you can see and avoid objects in the grass.
Before operating the tractor, be sure the side discharge guard is down, or that the optional grass catcher bags and discharge chute are in place.
Disengage the Power Take Off (P.T.O.1 lever to stop the blades before crossing a gravel driveway or any other area with loose stones. l
Always inspect the mower for damage after striking a foreign object. l
Repair or replace any damaged parts before continued use.
Broken pieces thrown from a worn or damaged blade can cause serious injury. Always inspect the blades before using the tractor.
Operation l Be sure to fasten the seat belt whenever driving the tractor with the
Rollover Protective Structure (ROPS) attached. Use of either device
(seat belt or ROPS) without the other will increase the chance of injury l l in a rollover.
Adjust the seat belt so that it is not slack.
Be sure that the main Transmission lever is in “Neutral” the front and l rear P.T.O. levers are in the “OFF” position before starting the engine.
Operate the tractor and its attachments at low speed until you become familiar with all of its operating characteristics and controls.
. Do not operate the tractor or its attachments without ensuring the area in front and behind is clear of people and.pets.
. Sudden stops of the tractor while driving at high speed or sudden start- up with the steering wheels turned fully in one direction, could cause the tractor to overturn.
. This tractor utilizes Four Wheel Steering (4WS) for a tighter turning cir- cle and greater mobility than tractors with conventional steering.
However, the feel of 4WS is slightly different from other tractors. Prac- tice driving in a wide, safe area.
. Never operate the tractor or its attachments when visibility is diminish- ed by darkness or bad weather; you ability to see obstacles will become impaired. l Watch out for rocks, roots, holes and other obstacles that may cause the Tractor to overturn.
. It is illegal to operate this tractor on public streets, roads, or highways.

- Do not apply while turning the tractor.
Use the lock only when driving straight ahead.
- Do not rest your foot on the lock pedal while the lock is not in use.
- Never apply while driving on a paved surface.
Operation on Slopes l
This tractor and its attachments are intended for use on relatively flat l terrain.
When operating the tractor on a slope, always drive up and down the l face of the grade. Turning or driving across the face of a slope may cause the tractor to overturn.
If you find it necessary to park on a grade, be sure to lock the parking l brake and securely block the wheels.
To avoid loss of control or overturning, always reduce speed and exer- cise extreme caution when operating on sloping or uneven surfaces. l Attempting to change gears while operating the tractor on a slope may adversely affect vehicle stability and control and severe personal injury l could result.
Avoid rapidly backing down, or rapidly accelerating up a sloping l surface.
To avoid loss of control or overturning, do not turn or stop on sloping l surfaces.
When descending a slope, disengaging the clutch or shifting to neutral l can cause a loss of control that may result in severe personal injury.
Do not operate the tractor near the edge of a ditch or an embankment, slipping off the edge could lead to severe personal injury and equipment damage.

6. OPERATION m
Never run the engine in an enclosed area. Be sure to provide adequate ventilation. Exhaust contains poisonous carbon monoxide gas that may cause loss of consciousness and lead to death.
1. Adjusting cutting height m
Be sure all moving parts have stopped before adjusting cutting height. Contacting moving parts can cause injury.
- 1. Park the tractor on a level surface and set the parking brake.
- 2. Make sure the main transmission lever is in “NEUTRAL”, both the front and rear P.T.O. levers are “OFF” and the lift lever is in the center (Neutral) position.
- 3. Start the engine, move the hydraulic cylinder selector lever (optional part) to “FRONT” and raise the cutter deck fully with the hydraulic lift lever.
- 4. Turn the descent speed adjust knob fully clockwise.
- 5. Push the hydraulic lift lever toward “DOWN” to be sure that the cut- ter deck is locked in the fully raised position. Return the lift lever to
“NEUTRAL” and then stop the engine and remove the ignition key.
- 6. Remove the lock pin and the link pin from the gauge wheel and set the wheel for the-desired cutting height.
LOCK PIN
- 7. Insert the link pin in the gauge wheel shaft and secure it with the lock pin.
- 8. Repeat the adjustment procedure for the other gauge wheel.
NOTE: Both gauge wheels must be set to the same height.

4. Two and Four Wheel Drive (A4 Type only)
Two and four wheel drive can be selected by operating the two-and four- wheel drive select lever.
Prior to shifting, set the steering wheel in the straight-ahead position, br- ing the tractor to a complete stop and depress the clutch pedal fully.
NOTE: If difficulty is encountered in shifting the lever, re-engage the gears by driving the tractor a short distance in FORWARD with the clutch engaged. In 4-wheel drive, the front wheels will operate with a greater traction when rounding corners, causing the lawn to be stripped off the ground by the wheels.
TWO AND FOUR WHEEL DRIVE

L\\ \\
We recommend that you select the two wheel drive and the four wheel drive according to the terrain and conditions.
2-WHEEL DRIVE . . . . . . . . Mowing and transport (when extra traction is not required).
4-WHEEL DRIVE . . . . . . . Towing, Operation on slope or soft ground,
Operation with attachment installed (Especially when powerful driving force and braking force are required).
1 NOTICE ] l l
To prevent damage to the transmission mechanism, bring the tractor to a full stop before operating the shift lever.
Driving in 4-WHEEL DRIVE range or with the differential locked on pav- l ed surface could cause premature wear on the tires, it could also impair fuel economy.
When driving in four wheel drive, you have 4-wheel braking. When shifted into two wheel drive you have 2-wheel braking (rear only).

5. Mowing
Before operating this tractor you should read and understand the SAFETY
INFORMATION
l l
Rotating blades and thrown objects can cause severe personal injury.
Always stop the engine before clearing the discharge cover.
Unseen hazards may cause loss of control or damage to the tractor.
Look for and avoid rocks, roots, holes, and hidden hazards in the l l terrain.
Operating the tractor near the edge of a ditch or an embankment could cause it to tip or roll over.
Certain maneuvers can cause the tractor to tip or roll over on sloping surfaces; avoid sharp turns, rapid acceleration, and sudden stops.
Also, avoid backing down slopes. l
Decomposing grass creates heat, and may become a fire hazard.
Always empty the grass bags before storing the tractor.
When mowing tall grass, make a first pass with the deck fully raised (4 inch position) this will help to expose any hidden obstacles. When you are sure that the area is completely cleared, mow again at the desired height. w If the tractor should accidentally get caught on an unseen object
(rock, root, hole, etc.), do not attempt to ride over the obstruction or turn the steering wheel to free the mower. These actions can damage the steering mechanism or the deck.
MOWING TIPS
1. Mow at full throttle to give a neat appearance to the lawn. The lawn may not be trimmed uniformly at medium or low engine speeds.
2. Observe the following when mowing:
4th gear
5/6th gear
7th gear
Heavy cutting
Normal cutting
Light cutting or trimming or transportation
8th gear Use only for transportation
3. Do not allow the grass to grow too long before cutting or trimming. Also allow the lawn to dry thoroughly before you use the mower. To cut a thick or lush lawn, mow at low speed or cut twice.
4. Always turn counterclockwise at low ground speed when cutting close to trees, posts, sprinkers, walls, etc.
5. You may cut the lawn too short when the lawn is thick or wet, and/or the ground is soft, due to sinking of the gauge wheels.
6. Increase the cutting height if the lawn is spindly, and the surface
38 uneven.
6. Cutting patterns
These cutting patterns are only recommended for a flat, level lawn surface. l
In a small area
First make 2 or 3 turns in a clockwise direction; then turn around and continue cutting in the reverse direction. l
In a large area
The first round of cuts is the key to making a neat finish. First, make 2 or 3 turns in a clockwise direction. As you reach the center of the area, turn to the right and continue cutting in the reverse direction until you have finished the upper half of the area. Cut the grass in the remaining half in a counterclockwise direction.
39
Mowing unsquare areas
If your mowing area is not square or four-sided, divide the area into several blocks so you can mow in a neat mowing pattern.
Overlapping on straightaways.
Be sure that each mowing lane overlaps sufficiently. The recommended overlap width is between 4-6 in., or approximately the width of one of the mower’s front tires.
1st
Overlapping in curves and turns
4-6”
When cutting in curves and turns, shift to a slower speed and be sure to overlap the previous cut by 50%, or approximately half the width of the mower.

7. Stopping m
To avoid injury to yourself and others, before leaving the trac- tor unattended, ALWAYS: park on level ground, disengage the power take-off (P.T.O.), lower the cutter deck, shift into neutral, set the parking brake, stop the engine and remove the key. l
In an emergency:
Turn the engine switch OFF.
Depress the clutch and brake pedal. l In normal use:

7. MAINTENANCE
Periodic maintenance and adjustment are necessary to keep the tractor in good operating condition. Service and inspect according to the
MAINTENANCE SHCEDULE.
To avoid carbon monoxide poisoning, shut off the engine before perfor- ming any maintenance. If you run the engine in an area that is confined, or even partially enclosed, the air you breathe will contain a dangerous amount of exhaust gas. If the engine must be run for any reason, be sure the area is well-ventilated.
To avoid serious burns, allow the engine to cool before performing maintenance.
Shut the engine off and set the parking brake before performing any maintenance.
To prevent accidental start-up, remove the ignition switch key and disconnect the spark plug caps.
