SECTION 1: MAINTAINING SAFETY

This Warning 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.

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.

WARNING:

The Engine Exhaust from this product contains chemicals known to the State of

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

GENERAL OPERATION

• Read this operator’s manual carefully in its entirety before attempting to assemble this machine. Read, understand, and follow all instructions on the machine and in the manual(s) before operation. Be completely familiar with the controls and the proper use of this machine before operating it. Keep this manual in a safe place for future and regular reference and for ordering replacement parts.

• Your rotary mower is a precision piece of power equipment, not a plaything. Therefore, exercise extreme caution at all times. Your unit has been designed to perform one job: to mow grass. Do not use it for any other purpose.

• Never allow children under 14 years old to operate a power mower. Children 14 years old and over should only operate mower under close parental supervision.

Only responsible individuals who are familiar with these rules of safe operation should be allowed to use your mower.

• Keep the area of operation clear of all persons, particularly small children and pets. Stop engine when they are in the vicinity of your mower to help prevent blade contact or thrown object injury.

Although the area of operation should be completely cleared of foreign objects, an object may have been overlooked and could be accidentally thrown by the mower in any direction and cause serious personal injury to the operator or any others allowed in the area.

• Wear sturdy, rough-soled work shoes and close-fitting slacks and shirts. Shirts and pants that cover the arms and legs and steel-toed shoes are recommended. Do not wear loose fitting clothes or jewelry. They can be caught in moving parts. Never operate a unit in bare feet, sandals, slippery or light weight (e.g. canvas) shoes.

• Always wear safety glasses or safety goggles during operation or while performing an adjustment or repair, to protect eyes from foreign objects that may be thrown from the machine in any direction.

• Thoroughly inspect the area where the equipment is to be used. Remove all stones, sticks, wire, bones, toys and other foreign objects which could be picked up and thrown by the mower in any direction and cause serious personal injury to the operator or any others allowed in the area. Plan your mowing pattern to avoid discharge of material toward roads, sidewalks, bystanders and the like. To help avoid a thrown objects injury, keep children, bystanders and helpers at least 75 feet from the mower while it is in operation.

• Do not put hands or feet near or under rotating parts.

Keep clear of discharge opening at all times as the rotating blade can cause injury.

• Many injuries occur as a result of the mower being pulled over the foot during a fall. Do not hang on to the mower if you are falling; release the handle immediately.

• Never pull the mower toward you while you are walking. If you must back the mower away from a wall or obstruction first look down and behind, and then follow these steps:

• Step back from the mower to fully extend your arms.

• Be sure you are well balanced with sure footing.

• Pull the mower back slowly, no more than half way toward you.

• Repeat these steps as needed.

• Do not operate the mower while under the influence of alcohol or drugs.

• Do not engage the self-propelled mechanism on units so equipped while starting engine.

• The blade control handle is a safety device. Never attempt to bypass its operation. Doing so makes the safety device inoperative and may result in personal injury through contact with the rotating blade. The blade control handle must operate easily in both directions and automatically return to the disengaged position when released.

3

• Never operate the mower in wet grass. Always be sure of your footing. A slip and fall can cause serious personal injury. Keep a firm hold on the handle and walk, never run. If you feel you are losing your footing, RELEASE THE BLADE CONTROL HANDLE

IMMEDIATELY and the blade will stop rotating within three seconds.

• Mow only in daylight or good artificial light.

• Stop the blade when crossing gravel drives, walks or roads.

• If the equipment should start to vibrate abnormally, stop the engine and check immediately for the cause.

Vibration is generally a warning of trouble.

• Shut the engine off and wait until the blade comes to a complete stop before removing the grass catcher or unclogging the chute. The cutting blade continues to rotate for a few seconds after the engine is shut off.

Never place any part of the body in the blade area until you are sure the blade has stopped rotating.

• Never operate mower without proper guards, grass catcher, plates or other safety protective devices in place.

• Muffler and engine become hot and can cause a burn. Do not touch.

• Only use accessories approved for this machine by the manufacturer. Read, understand, and follow all instructions provided with the approved accessory.

• If situations occur which are not covered in this manual, use care and good judgment. Contact your dealer for assistance. Telephone 1-800-800-7310 for the name of your nearest dealer.

SLOPE OPERATION

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 degrees as shown on the slope gauge, do not operate this unit on that area or serious injury could result.

DO:

• Mow across the face of slopes; never up and down.

Exercise extreme caution when changing direction on slopes.

• Watch for holes, ruts, hidden objects, or bumps. Tall grass can hide obstacles.

• Always be sure of your footing. A slip and fall can cause serious personal injury. If you feel you are losing your balance release the blade control handle immediately and the blade will stop in less than 3 seconds.

DO NOT:

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

The operator could lose footing or balance.

• Do not mow slopes greater than 15 degrees as shown on the slope gauge.

• Do not mow on wet grass. Reduced footing could cause slipping.

CHILDREN

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the mower and the 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 a responsible adult other than the operator.

• Be alert and turn mower off if a child enters the area.

• Before and while moving backwards, look behind and down for small children or other objects.

• Never allow children under age 14 to operate the mower. Children 14 years of age and above should read and understand the operation instructions and safety rules in this manual.

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

SERVICE

• Use extreme care in handling gasoline and other fuels. They are extremely flammable and the vapors are explosive.

• Use only an approved gasoline container.

• Never remove gas cap or add fuel while the engine is running. Allow engine to cool at least two minutes before refueling.

• Replace gasoline cap securely and wipe off any spilled gasoline before starting the engine as it may cause a fire or explosion.

• Extinguish all cigarettes, cigars, pipes and other sources of ignition.

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

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

• Never run an engine inside a closed area.

• To reduce fire hazard, keep mower free of grass, leaves, or other debris build-up. Clean up oil or fuel spillage. Allow mower 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., bent, cracked or worn). Replace with blade which meets original equipment specifications listed in this manual.

4

SECTION 5: OPERATING YOUR LAWN MOWER

Towards Better Mower Performance

1.

Pour fresh, clean gasoline into the mower’s gas tank until the tank is full. Do not use gasoline that is more than 30 days old.

2.

Always use a fuel stabilizer. It will double the life of the gasoline used.

3.

Make sure to connect the mower’s spark plug wire before trying to start the engine.

4.

Add engine oil to the oil fill on the mower engine.

Check the dipstick and add more if necessary.

Remember that the oil level has to touch the fill line.

5.

Locate the primer decal near the primer bulb on the engine, and read its instruction. Using your thumb, press the primer bulb slowly as many times as the decal advises.

6.

Hold control handle down and pull rope firmly to start the engine.

7.

Set cutting height adjustment lever to middle setting and mow a single pass on your lawn; then adjust to desired height for a closer cut.

8.

To mulch insert the mulch plug/cover on the mower.

9.

In heavy growing season, it may be necessary to mow lawn twice weekly. Clumps of grass clippings left behind on the lawn usually means that the grass is too high to mulch.

10. Before storing the lawn mower for the winter, use stabilizer-treated fuel and run the tank dry.

11. Thirty days before start of the new season, check the air filter, spark plug and blade on the lawn mower, and replace if needed.

WARNING: Keep hands and feet away from chute area on the cutting deck. The operation of any lawn mower can result in foreign objects being thrown into the eyes, which can result in severe eye damage.

Always wear safety glasses or eye shields.

NOTE: For shipping purposes your mower is set with

the wheels in a low cutting height position. For best results raise the cutting position until it is determine which height is best for your lawn. See the Adjustment

Section for details.

9

Gas and Oil Fill-Up

Service the engine with gasoline and oil as instructed in the separate engine manual packed with your mower.

Read instructions carefully.

WARNING: Never fill fuel tank indoors with engine running or until the engine has been allowed to cool for at least two minutes after running.

Starting Engine

• Attach spark plug wire to spark plug. Make certain the metal cap on the end of the spark plug is fastened securely over the metal tip on the spark plug.

• Prime engine as instructed in the separate engine manual packed with your unit.

• Your lawn mower may be equipped with a constant speed throttle, which is set at full throttle for best performance.

• Stand behind the mower and squeeze the blade control handle against the upper handle.

• Grasp recoil starter handle and pull rope out slowly until engine reaches the start of compression cycle

(rope will pull slightly harder at this point). Let the rope rewind slowly. Pull rope with a rapid, continuous, full arm stroke. Keeping a firm grip on the starter handle, let the rope return to the starter slowly.

Using Your Lawn Mower

Be sure that the lawn is clear of stones, sticks, wire, or other objects which could damage the lawn mower or the engine. Such objects could be accidently thrown by the mower in any direction and cause serious personal injury to the operator and others.

For best results, do not cut wet grass because it tends to stick to the underside of the mower, preventing proper discharge of grass clippings, and could cause you to slip and fall. New grass, thick grass, or wet grass may require a narrower cut.

For a healthier lawn, never cut off more than one-third of the total length of the grass. Your lawn should be cut in the fall as long as there is growth. This mower is designed to be operated at full throttle to give you the best cut and do the most effective job of mowing or mulching.

WARNING: If you strike a foreign object, stop the engine. Remove wire from the spark plug, thoroughly inspect the mower for any damage, and repair the damage before restarting and operating the mower. Extensive vibration of the mower during operation is an indication of damage. The unit should be promptly inspected and repaired.

Mulching

For effective mulching, do not cut wet grass because it tends to stick to the underside of the deck, preventing proper mulching of grass clippings. New or thick grass may require a narrower cut. The ground speed should be adjusted to the condition of the lawn. If mowing has been delayed and the grass has been allowed to grow in excess of 4”, mulching is not recommended. Mow using the side discharge to reduce the grass height to 3

1/4” maximum before mulching.

SECTION 6: MAKING ADJUSTMENTS

Cutting Height Adjustment

Height Adjustment

Lubrication

Always stop engine and disconnect spark plug wire before cleaning, lubricating or doing any kind of service work on the lawn mower.

Lubricate

• The spark plug should be cleaned and the gap reset once a season. Spark plug replacement is recommended at the start of each mowing season.

Clean the engine regularly with a cloth or brush. Keep the cooling system (blower housing area) clean to permit proper air circulation which is essential to engine performance and life. Be certain to remove all grass, dirt, and combustible debris from muffler area.

Deck

The underside of the mower deck should be cleaned after each use to prevent a buildup of grass clippings, leaves, dirt, or other matter. If this debris is allowed to accumulate, it will invite rust and corrosion, and may prevent proper mulching, discharge, or bagging. The deck may be cleaned by tilting the mower and scraping clean with a suitable tool (make certain the spark plug wire is disconnected).

IMPORTANT:

We do not recommend the use of a pressure washer or garden hose to clean your unit.

Cutting Blade Removal, Replacement, and Sharpening

• When removing the cutting blade for sharpening or replacement, protect your hands with a pair of heavy gloves or use a heavy rag to hold the blade.

• Remove the bolt and the blade bell support which hold the blade and the blade adapter to the engine crankshaft. See Figure 12.

• Remove the blade and the adapter from the crankshaft.

Lubricate

Figure 11

Blade Control Handle: Lubricate the pivot points on the blade control handle at least once a season with light oil. The blade control must operate freely in both directions. See Figure 11.

Wheels: Lubricate the wheels at least once a season with light oil (or motor oil). If the wheels are removed for any reason, lubricate the surface of the axle bolt and inner surface of the wheel with light oil.

Chute Deflector or Mulching Baffle: Lubricate the torsion spring and pivot point periodically with light oil to prevent any rust or binding.

Engine: Follow the separate engine manual packed with you unit for lubrication instructions.

Maintenance

NOTE: When tipping the unit, empty the fuel tank and

keep the spark plug side of engine up. Never tip the mower more than 90 degrees and do not leave the mower tipped for any length of time. Oil can drain into the upper part of the engine causing a starting problem.

Engine

Refer to the separate engine manual for all engine maintenance instructions.

• Maintain engine oil as instructed in the separate engine manual packed with your unit.

• Service air cleaner every 25 hours under normal conditions. Poor engine performance and flooding usually indicate that the air cleaner should be serviced. To service the air cleaner, refer to the separate engine manual packed with your unit.

Blade

Adapter

Blade Bell

Support

Hex Bolt

Figure 12

WARNING: Periodically inspect the blade adapter for cracks, especially if you strike a foreign object. Replace when necessary.

When sharpening the blade, 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. It may cause damage to the mower, and could break causing personal injury.

12

The blade can be tested by balancing it on a round shaft screwdriver. Remove metal from the heavy side until it balances evenly. It is recommended that the blade always be removed from the adapter when testing for balance. Before reinstalling the blade and the blade adapter to the unit, lubricate the engine crankshaft and the inner surface of the blade adapter with light oil.

• Be sure to install the blade with the end tips facing up or side of the blade marked “Bottom” (or with part number) facing the ground when the mower is in the operating position.

• Slide the blade adapter onto the engine crankshaft.

• Place the blade on the adapter. Be certain the blade is aligned and seated on the blade adapter flanges.

• Place blade bell support on blade. Make sure the notches on the blade bell support are aligned with small holes in the blade.

• Replace hex bolt and tighten hex bolt to torque: 450 in. lbs. min., 600 in. lbs. max.

NOTE: To ensure safe operation of your mower, the

blade bolt must be checked periodically for correct torque.

This limited warranty shall only apply if this product has been operated and maintained in accordance with the Operator’s Manual furnished with the product, and has not been subject to misuse, abuse, commercial use, neglect, accident, improper maintenance, alteration, vandalism, theft, fire, water or damage because of other peril or natural disaster. Damage resulting from the installation or use of any accessory or attachment not approved by MTD Products Inc. for use with the product(s) covered by this manual will void your warranty as to any resulting damages.

Normal wear parts or components thereof are subject to separate terms as follows: All normal wear part or component failures will be covered on the product for a period of 90 days regardless of cause. After 90 days, but within the two year period, normal wear part failures will be covered ONLY IF caused by defects in material or workmanship of OTHER component parts. Normal wear parts and components include, but are not limited to, belts, blades, blade adapters, grass bags, rider deck wheels, seats, snow thrower skid shoes, shave plates and tires. Batteries are covered by a 90day limited replacement warranty.

This limited warranty does not provide coverage in the following cases:

a. The engine or component parts thereof. These items carry a separate manufacturer’s warranty. Please refer to the applicable manufacturer’s warranty on these items.

b. Log splitter pumps, valves and cylinders have a separate one year warranty.

c. Routine maintenance items such as lubricants, filters, blade sharpening and tune-ups, or adjustments such as brake adjustments, clutch adjustments or deck adjustments; and normal deterioration of the exterior finish due to use or exposure.

d. MTD 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’s authorized channels of export distribution.

No implied warranty, including any implied warranty of merchantability or fitness for a particular purpose, applies after the applicable period of express written warranty above as to the parts as identified. No other express warranty or guaranty, whether written or oral, except as mentioned above, given by any person or entity, including a dealer or retailer, with respect to any product shall bind MTD. During the period of the Warranty, the exclusive remedy is repair or replacement of

the product as set forth above. (Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.)

The provisions as set forth in this Warranty provide the sole and exclusive remedy arising from the sales.

uct. (Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above exclusion or limitation may not apply to you.)

In no event shall recovery of any kind be greater than the amount of the purchase price of the product sold. Alteration of the safety features of the product shall void this Warranty.

You assume the risk and liability for loss, damage, or injury to you and your property and/or to others and their property arising out of the use or misuse or inability to use the product.

This limited warranty shall not extend to anyone other than the original purchaser, original lessee or the person for whom it was purchased as a gift.
