SECTION 1: 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.

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.

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 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. 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, 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.

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.

• 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 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.

• Use extra care when approaching blind corners, 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.

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.

•

• We do not recommend the use of pressure washers or garden hose to clean your unit. They may cause damage to electric components, spindles, pulleys, bearings or the engine. The use of water will result in shortened life and reduce serviceability.

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

Clean the underside of the deck after each mowing.

We do not recommend the use of pressure washers or garden hose to clean your unit. They may cause damage to electric components, spindles, pulleys, bearings or the engine. The use of water will result in shortened life and reduce serviceability.

Cutting Blades

REMOVAL FOR REPLACEMENT OR SHARPENING

WARNING: Be sure to disconnect and ground the spark plug wire(s) and remove ignition key before working on the cutting blade to prevent accidental engine starting. Protect hands by using heavy gloves or a rag to grasp the cutting blades.

• Remove the hex flange nut which holds the blade to the blade spindle.

• Remove the blade from the spindle.

Sharpening

Remove the cutting blades by following the directions of the preceding section. When sharpening the blades, follow the original angle of grind as a guide. It is extremely important that each cutting edge receives an equal amount of grinding to prevent an unbalanced blade. An unbalanced blade will cause excessive vibration when rotating at high speeds, may cause damage to the mower and could break, causing personal injury. The blade can be tested for balance by balancing it on a round shaft screwdriver. Remove metal from the heavy side until it balances evenly.

Reassembly

When replacing blades, be sure to install the blade with the side of the blade marked ‘‘Bottom’’ (or with part number) facing the ground when the mower is in the operating position. Carefully align “star” on blade with “star” on spindle. Secure with hex flange nut.

Blade Mounting Torque

Hex Flange Nut: 840 in. lb. min., 1080 in. lb. max. To ensure safe operation of your unit, all nuts and bolts must be checked periodically for correct tightness.

Battery Care And Maintenance (Type “B” Battery)

Check Fluid Level

Check fluid level inside each cell of the battery every two weeks and before and after charging. Always keep level between maximum and minimum fill level.

Add only distilled water. Never add additional acid or any other chemicals to the battery after initial activation.

NOTE: After operating the lawn tractor for a long period of time, check the fluid level in the battery as it can overheat and lose fluid.

Charging The Battery (All Batteries)

The engine is equipped with an alternator which charges battery when tractor is operated. Under normal conditions, the battery only needs to be charged before, during and after off-season storage. Follow the instructions under “Off-Season Storage.”

To charge the battery: Battery P/N 725-1705D— Charge at 2-3 amps for one hour. Battery P/N 7251707D, 725-0453G, and 725-1750—Charge at 6 amps for one hour.

SECTION 10: TROUBLE SHOOTING GUIDE

Trouble

Engine will not crank

Engine cranks but will not start

Engine smokes

Excessive vibration

Mower will not discharge grass or leaves uncut strips

Possible Cause(s)

Safety switch button not depressed. Battery installed incorrectly.

Battery is dead or weak. Blown fuse or circuit breaker.

Engine ground wire loose. Throttle or choke not in starting position. No fuel to the carburetor.

No spark to spark plug.

Dirty air cleaner.

Engine oil has been overfilled. Engine loses crankcase vacuum. Bent or damaged blade. Bent blade.

Engine speed low. Speed selection. Cutting height set too low. Blades short or dull.

Corrective Action

There are two switches in the starting circuit of your unit: the clutch pedal switch and the deck lift lever switch. Make certain the actuator is fully depressing the buttons on each switch. The battery 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, identified by “POS”, “P” or “+”, must be attached to the big red wire which goes to the solenoid. All batteries are to be fully charged before installing. Refer to “Quick Start” battery guide that came with the operator’s manual. Check fluid level in battery. If fluid is low, fill to just below split rings with water. Charge with 6 AMP charger until fully charged. Refer to operator’s manual for fuse box location. Replace fuse with automotive type fuse. Fuses seldom fail without a reason. The problem must be corrected. Check for loose connections in the fuse holder. Replace fuse 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. Engine should have a black ground wire running from engine to frame or mounting bolt. Check operator's manual for correct position for throttle control and choke for starting.

Gasoline tank empty. Fill. Fuel line or in-line fuel filter plugged. Remove and clean fuel line. Replace filter if necessary. Spark plug lead disconnected. Connect lead. Hold spark plug lead away from engine block about 1/8". Crank engine. There should be a spark. If not, have engine repaired at authorized engine service dealer. Faulty spark plug. To test, remove spark plug. Attach spark plug lead to spark plug. Ground the spark plug body against the engine block. Crank the engine. The spark plug should fire at the electrode. Replace if it does not. If the air cleaner is dirty, the engine may not start. Refer to the engine manual packed with your unit. Check oil level.

Dipstick not seated or broken. Replace defective part. Engine breather defective. Replace.

Stop engine immediately. Check all pulleys, blade adapters, keys and bolts for tightness and spindle damage. Tighten or replace any damaged parts. Stop engine immediately. Replace damaged blade. Only use original equipment blades. Throttle must be set at full throttle.

Use lower ground speed. The slower your ground speed, the better the quality of cut. Raise deck.

Sharpen or replace blades (uncut strip problem only).

NOTE: For repairs beyond the minor adjustments above, contact your local authorized service dealer.
