DANGER: Your lawn mower was built to be operated according to the rules for safe operation in this

manual. As with any type of power equipment, carelessneSS or error on the part of the operator can result in serious injury. This lawn mower is capable of amputating hands and feet and throwing objects. Failure to observe the following safety instructionscould result in serious injury or death.

1. GENERAL OPERATION

• Read, understand, and follow all instructions in the • operator's manual and on the machine before starting. Keep this manual in a safe place for future and regular reference and for ordering replacement

pads, •

• Only allow responsible individuals familiar with the •

instructions to operate the machine. Know controls

and how to stop the machine quickly.

• Do not put hands or feet under cuttingdeck or near

rotatingparts.

• Clear the area of objects such as rocks, toys, wire,

etc., which could be picked up and thrown by the blade. A small object may have been overlooked and could be agcidantally thrown by the mower in any ° direction and cause injury to you or a bystander. To help avoid a thrown objects injury, keep children, • bystanders and helpers at least 75 feet from the mower while it is in operation, Always wear safety glasses or safety goggles during operation or while performing an adjustment or repair, to protect eyes from foreign objects. Stop the blade(s) when crossing gravel drives, walks or roads.

• Be sure the area is clear of other people before

mowing. Stop machine if anyone enters the area.

• Never carry passengers.

• Disengage blade(s) before shifting into reverse and

backing up. Always look down and behind before and while backing.

• Be aware of the mower and attachment discharge

direction and do not point it at anyone. Do not operate the mower without either the entire grass catcher or the chute guard in place.

• Slow down before turning. Operate the machine

smoothly. Avoid erratic operation and excessive speed.

Never leave a running machine unattended. Always turn off blade(s), place transmission in neutral set park brake, stop engine and remove key before dismounting.

Turn offblade(s)whennotmowing. Stop engine and wait until blade(s) comes to a

completestop before (a) removinggrass catcher or

unclogging chute, or (b) making any repairs, adjustingorremovinganygrassor debris.

Mow only in daylight or good artificial light. Do not operate the machine while under the

influence of alcohol or drugs.

Watch for traffic when operating near or crossing

roadways.

Use extra care when loading or unloading the machine into a trailer or truck. This unit should not be

driven up or down a ramp onto a trailer or truck under power, because the unit could tip over, causing sedous personal injury. The unit must be pushed manually on a ramp to load or unload prepedy.

Never make a cutting height adjustment while engine is running it operator must dismount to do so.

Wear sturdy, rough-soled work shoes and close- fitting slacks and shirts. Do not wear loose _ting clothes or jewelry. They can be caught in moving parts. Never operate a unit in bare feet, sandals, or

sneakers.

Check overhead clearance carefully before driving under power lines, wires, bridges or low hanging tree branches, before entedng or leaving buildings, or in any other situation where the operator may be struck or pulled from the unit, which could result in serious injury.

Disengage all attachment clutches, thoroughly depress the brake pedal, and shift into neutral before attempting to start engine.

• Yourmoweris designedto cutnormalresidential

grass of a height no more than 10". Do not attempt to

mow through unusually tall, dry grass (e.g., pasture)

or piles of dry leaves. Debris may build up on the mower deck or contact the engine exhaust

presenting a potential fire hazard.

2. SLOPE OPERATION

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 ifyou feel uneasy on it, do not mow it.

For your safety, use the slope gauge included as pert of this manual to measure slopes before operating this unit on a sloped or hilly area. If the slope is greater than 15° as shown on the slope gauge, do not operate this unit on that area or serious injury could ras_lt

DO:

• Mow up and down slopes, not across.

• Remove oboes such as rooks, limbs, etc.

• Watch for holes, ruts or bumps. Uneven terrain could

overturn the machine. Tall grass can hide obstacles.

• Use slow speed. Choose a low enough gear so that you will not have to stop or shift while on the slope. Always keep machine in gear when going down

slopes to take advantage of engine braking action.

• Follow the manufacturer's recommendations for wheel weights or counterweights to improve stability.

• Use extra care with grass catchers or other

attachments. These can change the stability of the

machine.

• Keep all movement on the slopes slow and gradual.

Do not make sudden changes in speed or direction. Rapid engagement or braking could cause the front of the machine to lift and rapidly flip over backwards

which could cause serious injury.

• Avoid starting or stopping on a slope. If tires lose

traction, disengage the blade(s) and proceed slowly

straight down the slope.

DO NOT:

• Do not turn on slopes unless necessary; then, tum

slowly and gradually downhill, if possible. •

• Do not mow near drop-offs, ditches or embankments.

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

• Do not mow on wet grass. Reduced traction could

cause sliding.

• Do not try to stabilize the machine by puttingyour

footonthe ground.

• Do not use grass catcher on steep slopes.

3. CHILDREN

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

machine and the mowing activity. Never assume that children wilt remain where you tsst saw them.

• Keep children out of the mowing area and in watchful

care of an adult other than the operator.

• Be alert and turn machine off if children enter the

area,

• Before and when backing, look behind and down for

small children.

• Never carry children, even with the blades off. They

may fall off and be seriously injured or interfere with

the safe machine operation.

• Never allow childrenunder 14 years old to operate

the machine.Children14 years and overshouldonly operate machine under close parental supervision and properinstruction.

• Use extra care when approaching blind comers, shrubs, trees or other objects that may obscure your vision of a child or other hazard.

• Remove key when machine is unattended to prevent

unauthorized operation.

4. SERVICE

• Use extreme care in handling gasoline and other

fuels. They are extremely flammable and the vapors are explosive.

• Use only an approved container.

• Never remove fuel cap or add fuel with the engine

running. Allow engine to cool at least two minutes

before refueling.

• Replace fuel cap securely and wipe off any spilled

fuel before starting the engine as it may cause a fire

or explosion.

• Extinguish all cigarettes, cigars, pipes and other

sources of ignition;

• Never refuel the machine indoors because fuel vapors will accumulate in the area.

• Never store the fuel container or machine inside where there is an open flame or spark, such as a gas hot water heater, space heater or fumace.

• Never run a machine inside a closed area.

• To reduce fire hazard, keep the machine free of

grass, leaves or other ds_orisbuild-up. Clean up oil or fuel spillage. Allow machine to cool at least 5 minutes before storing.

• Before cleaning, repairing or inspecting, make certain the blade and all moving parts have stopped.

Disconnect the spark plug wire, and keep the wire away from the spark plug to prevent acc'ldenta| starting.

• Check the blade and engine mounting bolts at frequent intervals for proper tightness. Also, visually inspect blade for damage (e.g., excessive wear, bent, cracked). Replace with blade which meets original equipment specifications.

• Keep all nuts, bolts and screws tight to be sure the equipment is in safe working condition.

• Never tamper with safety devices. Check their

proper operation regularly. Use all guards as

instructed in this manual.

• After striking a foreign object, stop the engine, remove the wire from the spark plug and

thoroughly inspect the mower for any damage.

Repair the damage before restarting and operating

the mower.

• Grass catcher components are subject to wear, damage and deterioration, which could expose

moving parts or allow objects to be thrown. For

your safety protection, frequently check components and replace with manufacturer's

recommended parts when necessary.

• Mower blades are sharp and can cut. Wrap the

blade(s) or wear gloves and use extra caution when servicing blade(s).

• Check brake operation frequently. Adjust and

service as required.

Muffler, engine and belt guards become hot during operation and san cause a bum. Allow to cool down before touching.

Do not change the engine governor settings or overspeed the engine. Excessive engine speeds are dangerous.

Observe proper disposal laws and regulations.

Improper disposal of fluids and materials can harm

the environment and the ecology.

Prior to disposal, determine the proper method to dispose of waste from your local Environmental Protection Agency. Recycling centers are established to properly dispose of materials in an environmentally safe fashion.

Use proper containers when draining fluids. DO not use food or beverage containers that may mislead someone into drinking from them. Properly dispose of the containers immediately following the draining of fluids.

DO NOT pour oil or other fluids into the ground, down a drain or into a stream, pond, lake or other

GAS AND OIL FILL-UP

Check the oll level and add if necessary, Service

the engine with gasoline as instructed in the

separate engine manual packed with your

tractor. Read instructions carefully.

IMPORTANT:Your tractor is shippedwith oil; howeveryou must check the oil level before operating.Becarefulnottooverfill.

i_ WARNING: Neverfill fuel tank indoors,

with engine running or while engine is hot.

STARTING THE ENGINE

IMPORTANT: This unit is equipped with a safety

interlock system for your protection. The purpose of

the safety interlock system is to prevent the engine from cranking or starting unless the clutch-brake

pedal is depressed and the lift lever is in the BLADES STOP position. In addition, the lift lever must be in the BLADES STOP position when the unit is put into reverse or the engine will shut off. If

the operator leaves the seat with the lift lever engaged and/or without setting the parking brake,

the engine will shut off.

WARNING: Do not operate the tractor if the interlock system is malfunctioning

because it is a safety device, designed for protection,

Place the lift lever in the BLADES STOP position.

Depress the clutch-brake pedal and set the parking brake.

Set the throttle control in the FAST position. Pull out the choke control (a warm engine may

not require choking).

Turn the ignition key to the right to the START position. After the engine starts, release the key. It will return to the ON position.

NOTE: Protect the starter life by using short

starting cycles of several seconds. Cranking more than 15 seconds per minute can damage the starter

motor.

6. Push choke knob in gradually. Move the throttle control to desired engine speed.

STOPPING THE ENGINE

Turn the ignition key to the left to the OFF position.

Remove the key to prevent accidental starting.

IMPORTANT: If you strike a foreign object, stop

the engine. Remove wire from spark plug, thoroughly inspect the unit for any damage, and repair the damage before restarting and operating

the mower.

NOTE: ff any problems are encountered, refer to

the Trouble Shooting Guide onpage 24.

OPERATING THE LAWN TRACTOR

1. Move throttle control to full throttle to prevent strain on the engine and to operate the cutting

blades.

2. Place the shift lever in either the FORWARD or

REVERSE position.

Release the parking brake by depressing the clutch-brake pedal, pressing outward on the speed control lever and moving to desired posi- tion. Use first speed position when operating the

lawn tractor for the first time.

WARNING: Look to the rear before

backing up.

be little difference between the highest two speeds

until after the belts have seated themselves into the

pulleys during the break-in period.

Be sure that the lawn is clear of stones, sticks, wire, or other objects which could damage lawn mower or engine. For best results and to insure more even grass distribution, do not mow when lawn is excessively wet.

WARNING: Before leaving the

operator's position for any reason, disengage the blades, place the shift lever in neutral, engage the parking brake, shut

engine off and remove the key.

When stopping the unit to empty a grass bag, etc., follow the instructions above. This procedure will

also eliminate "browning" the grass, which is

caused by hot exhaust gases from a running engine.

If unit stalls with speed control in high speed, or if unitwill not operate with speed control lever in a low

speed position, proceed as follows.

1. Place shift lever in NEUTRAL.

2. Restart engine. 3, Place speed control lever in high speed position. 4, Release clutch-brake pedal fully.
