SECTION 4: IMPORTANT SAFE OPERATION PRACTICES

WARNING: THIS SYMBOL POINTS OUT IMPORTANT SAFETY INSTRUCTIONS WHICH, IF

NOT FOLLOWED, COULD ENDANGER THE PERSONAL SAFETY AND/OR PROPERTY OF YOURSELF AND OTHERS. READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL BEFORE ATTEMPTING TO OPERATE YOUR LAWN MOWER. FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY. WHEN YOU SEE THIS SYMBOL, HEED ITS WARNING.

WARNING: The Engine Exhaust from this product contains chemicals known to

the State of California to cause cancer, birth defects or other reproductive harm.

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 instructions could 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 parts.

• 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 cutting deck or near

rotating parts.

• 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 accidentally 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 off blade(s) when not mowing.

• Stop engine and wait until blade(s) comes to a complete stop before (a) removing grass catcher or unclogging chute, or (b) making any repairs, adjusting or removing any grass or 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 serious personal injury. The unit must be pushed manually on a ramp to load or unload properly.

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

• Wear sturdy, rough-soled work shoes and closefitting slacks and shirts. Do not wear loose fitting 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 entering 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.

• Your mower is designed to cut normal residential 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 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. For your safety, use the slope gauge included as part 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 result.

DO:

• Mow up and down slopes, not across.

• Remove obstacles such as rocks, limbs, etc.

• Watch for holes, ruts or bumps. Uneven terrain could overturn the machine. Tall grass can hide obstacles.

• Use slow speed. 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, turn 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 putting your foot on the 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 will remain where you last saw them.

•Keepchildrenoutofthemowingareaandin 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 children under 14 years old to operate the machine. Children 14 years and over should only operate machine under close parental supervision and proper instruction.

• Remove key when machine is unattended to prevent unauthorized operation.

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

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 furnace.

• Never run a machine inside a closed area.

• To reduce fire hazard, keep the machine free of grass, leaves or other debris build-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 accidental 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, whic h c ould 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 can cause a burn. Allow to cool

• 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 body of water. Observe Environmental Protection Agency regulations when disposing of oil, fuel, coolant, brake fluid, filters, batteries, tires and other harmful waste.

WARNING: To avoid possible injury, do

not allow anyone in the area of the tractor whilemowing.Eveniftheareatobe mowed has been cleared of foreign objects, small objects may be picked up and discharged by the mower.

• For best results it is recommended that the first two laps be cut with the discharge thrown towards the center. After the first two laps, reverse the direction to throw the discharge to the outside for the balance of cutting. This will give a better appearance to the lawn.

• Do not cut the grass too short. Short grass invites weed growth and yellows quickly in dry weather.

•Mowingshouldalwaysbedonewiththe engine at full throttle.

• Do not mow at high ground speed, especially if a mulch kit or grass collector is installed.

• Under heavier conditions it may be necessary to go back over the cut area a second time to get a clean cut.

• Do NOT attempt to mow heavy brush and weeds and extremely tall grass. Your tractor is designed to mow lawns, NOT clear brush.

• Keep the blades sharp and replace the blades when worn. Refer to the MAINTENANCE section of this manual for proper blade sharpening instructions.

WARNING: Never direct the discharge

of material toward bystanders or allow anyone near the machine while in operation.

IMPORTANT:

If the cutting edge of the blade has already been sharpened to within 5/8" of the wind wing radius, or if any metal separation is present, replace the blades with new ones. See Figure 21.

BATTERY

The battery is sealed and is maintenance-free. Acid levels cannot be checked.

• Always keep the battery cables and terminals clean and free of corrosive build-up.

• After cleaning the battery and terminals, apply a light coat of petroleum jelly or grease to the terminals and over the positive terminal boot.

• Always keep the boot positioned over the positive terminal to prevent shorting.

IMPORTANT:

reason, disconnect the NEGATIVE (Black) wire from it’s terminal first, followed by the POSITIVE (Red) wire. When re-installing the battery, always connect the NEGATIVE (Black) wire its terminal first, followed by the POSITIVE (Red) wire. Be certain that the wires are connected to the correct terminals. reversing them could change the polarity and cause damage to your engine’s alternating system.

If removing the battery for any

Charging

If the unit has not been put into use for an extended period of time, charge the battery with an automotive-type 12-volt charger for a minimum of one hour at six amps.

WARNING: Batteries give off an

explosive gas during and for some time after charging. Charge battery in a well ventilated area and do not allow a spark or an open flame near the battery.

TIRES

The recommended operating tire pressure is approximately 10 psi for the rear tires and 14 psi for the front tires. Refer to the tire sidewall for exact tire manufacturer’s recommended psi. Do not overinflate. Uneven tire pressure could cause the cutting deck to mow unevenly.

SECTION 11: LUBRICATION

FUSE

A fuse is installed in your tractor’s wiring harness to protect the tractor’s electrical system from damage caused by excessive amperage. Always use the same capacity fuse for replacement. If the electrical system does not function, or your tractor’s engine will not crank, first check to be certain that the fuse has not blown. It can be found under the hood mounted behind the top of dash panel on the support bar. Pull the fuse out and compare it with Figure 22 to determine if it is good or bad.

ENGINE

Lubricate the engine with motor oil as instructed in the separate engine manual packed with your unit.

PIVOT POINTS

Lubricate all pivot points (AutoDrive™pedal, brake pedal, etc.) at least once a season with light oil.

LINKAGE

Lubricate all the pivot points on the drive, brake and lift linkage at least once a season with SAE 30 engine oil.

STEERING GEAR

Lubricate the teeth of the steering gear with an all-purpose automotive grease every 25 hours of operation or once a season.

WHEELS

Both the front wheels and the rear wheels should be removed from the axles once a season. Lubricate the axles and the rims well with an all-purpose automotive grease before re-installing them.

FRONT AXLES

Your tractor may be equipped with zerk fittings on the ends of the front pivot bar. See Figure 10. Lubricate both the left and the right front axles with a grease gun at least once a season.

SECTION 12: TROUBLESHOOTING GUIDE

Trouble

Engine will not crank

Engine cranks but will not start

Possible Cause(s)

Safety switch button not depressed. Battery installed incorrectly.

Battery is dead or weak. Blown fuse

Throttleorchoke not in starting position. No fuel to the carburetor.

No spark to spark plug(s).

Corrective Action

There is one safety switch in the starting circuit of your unit: the brake pedal switch. Make certain the actuator is fully depressing the button on this switch. The Operator must be seated on the tractor in order to start the engine, also. The b attery must be installed with negative terminal attached to black ground wire. Negative terminal is identified at the post by “NEG”, “N” or “-”. The positive terminal, identifiedby “POS”, “P” or “+”, mu st be attached to the thick red wire which goes to the solenoid. Charge at six amps with a 12-volt automotive-typebattery charger for one hour or until fully charged. Refer to operator’s manual for fuse location. Replace fuse with automotive type fuse of the proper amperage. Fuses seldom fail without a reason. The problem must be corrected. Check for loose connections in the fuse holder. Replacefuse holder if necessary. A dead short may be in the cranking or charging circuit where the insulation may have rubbed through and exposed the bare wire. Replace the wire or repair with electrician's tape if the wire strands have not been damaged. Note: Look for a wire pinched between body panels, burned by the exhaust pipe or muffler or rubbed against a moving part. Refer to the OPERATION section of this manual for the correct position of the throttle control and choke for starting.

Gasoline tank empty. Fill. Fuel line or in-line fuel filter plugged. Remove and clean fuel line. Replace fuel filter (if so equipped) if necessary. Spark plug lead disconnected. Connect lead. Using a spark tester, check for spark. If no spark is present, have engine’s magneto serviced by an authorized engine dealer.

Normal wear parts are defined as batteries*, belts, blades, blade adapters, grass bags, rider deck wheels, seats, snow thrower skid shoes, shave plates and tires.

How to obtain service: Warranty service is available, with proof of purchase, through your local authorized service dealer.

The return of a complete unit will not be accepted by the factory unless prior written permission has been extended by the Customer Support Department of MTD PRODUCTS INC.

Transportation charges: Transportation charges for the movement of any power equipment unit or attachment are the responsibility of the purchaser.

Units exported out of the United States: MTD PRODUCTS INC does not extend any warranty for products sold or exported outside of the United States of America, its possessions and territories, except those sold through MTD PRODUCTS INC’s authorized channels of export distribution.

2. *Batteries are covered by a 90-day replacement warranty.

3. Log splitter pumps, valves and cylinders or component parts thereof are covered by a one year warranty.
