29. If situations occur which are not covered in this manual, use care and good judgment. Contact your customer service representative for assistance.

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 n ot mow it.

For your safety, use the slope gauge included as part o f 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:

1. Mow up and down slopes, not across. Exercise extreme caution when changing direction on slopes.

2. Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles.

3. Use slow speed. Choose a low enough speed setting so that you will not have to stop or shift while on the slope. Tires may lose traction on slopes even though the brakes are functioning properly. Always keep machine in gear when going down slopes to take advantage of engine braking action.

4. Follow the manufacturer’s recommend ations for wheel weights or counterweights to improve stability.

5. Use extra care with grass catchers or other attachments. These can change the stability of the machine.

6. Keep all movement on the slopes slow and gradual. Do not make sudden changes in speed or dir ection. Rapid engagement or braking could cause the f ront of the machine to lift and rapidly flip over backwards which could cause serious injury.

7. Avoid starting or stopping on a slope. If tires lose traction, disengage the blade(s) and proceed slowly straight down the slope.

DO NOT:

1. Do not turn on slopes unless necessary; then, turn slowly and gradually downhill, if possible.

2. 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, ditch, or if an edge caves in.

3. Do not try to stabilize the machine by putting your foot on the ground.

4. Do not use a grass catcher on steep slopes.

5. Do not mow on wet grass. Reduced traction could cause sliding.

6. Do not shift to neutral and coast downhill. Overspeeding may cause the operator to lose control of the machine resulting in serious injury or death.

7. Do not tow heavy pull behind attachments (e.g. loaded dump cart, lawn roller, etc.) on slopes greater than 5 degrees. When going down hill, the extra weight tends to push the tractor and may cause you to loose control. (e.g. tractor may speed up, braking and steering ability are reduced, attachment may jack-knife and cause tract or to overturn).

CHILDREN

1. Tragic accidents can occur if the operator is not alert to the presence of children. Children are of ten attracted to the machine and the mowing activity. They do not understand the dangers. Never assume that children will remain where you last saw them.

a. Keep children out of the mowing area and in

watchful care of a responsible adult other than the operator.

b. Be alert and turn machine off if a child enters

the area.

Page 5

c. Before and while backing, look behind and

down for small children.

d. Never carry children, even with the blade(s)

shut off. They may fall off and be seriously injured or interfere with safe machine operation.

e. Use extreme care when approaching b lind

corners, doorways, shrubs, trees or other objects that may block your vision of a child who may run into the machine.

f. Disengage the cutting blade(s) be fore

shifting in reverse. The “No-Cut-In Reverse” feature is a reminder not to cut in reverse and to help avoid back over accidents. Do not defeat it.

g. Keep children away from hot or running

engines. They can suffer burns from a hot muffler.

h. Remove key when machine is unattended to

prevent unauthorized operation.

9. Never allow children under 14 years old to operate the machine. Children 14 years old and over shou ld read and understand the operation instructions and safety rules in this manual and should be trained and supervised by a parent.

TOWING

1. Tow only with a machine that has a hitch designed for towing. Do not attach towed equipment except at the hitch point.

2. Follow the manufacturers recommendation for weight limits for towed equipment and towing on slopes.

3. Never allow children or others in or on towed equipment.

4. On slopes, the weight of the towed equipment may cause loss of traction and loss of control.

5. Travel slowly and allow extra distance to stop.

6. Do not shift to neutral and coast downhill.

SERVICE

SAFE HANDLING OF GASOLINE:

1. To avoid personal injury or property damage use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Serious personal injury can occur when gasoline is spilled on yourself or your clothes which can ignite. Wash your skin and change clothes immediately.

a. Use only an approved gasoline container. b. Never fill containers inside a vehicle or on a

truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before filling.

c. When practical, remove gas-powered

equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment on a trailer with a portable container, rather than from a gasoline dispenser nozzle.

d. Keep the nozzle in contact with the rim of the

fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.

e. Extinguish all cigarettes, cigars, pipes and

other sources of ignition. f. Never fuel machine indoors. g. Never remove gas cap or add fuel while the

engine is hot or running. Allow engine to cool

at least two minutes before refueling. h. Never over fill fuel tank. Fill tank to no more

than ½ inch below bottom of filler neck to

allow space for fuel expansion. i. Replace gasoline cap and tighten securely. j. If gasoline is spilled, wipe it off the engine

and equipment. Move unit to another area.

Wait 5 minutes before starting the engine. k. To reduce fire hazards, keep machine free of

grass, leaves, or other debris build-up. Clean

up oil or fuel spillage and remove any fuel

soaked debris. l. Never store the machine or fuel container

inside where there is an open flame, spark or

pilot light as on a water heater, space heater,

furnace, clothes dryer or other gas

appliances. m. Allow a machine to cool at least five minutes

before storing.

GENERAL SERVICE:

1. Never run an engine indoors or in a poorly ventilated area. Engine exhaust contains carbon monoxide, an odorless, and deadly gas.

2. Before cleaning, repairing, or inspecting, make certain the blade(s) and all moving parts have stopped. Disconnect the spark plug wire and ground against the engine to prevent unintended starting.

3. Periodically check to make sure the blades come to complete stop within approximately (5) five seconds after operating the blade disengagement control. If the blades do not stop within the this time frame, your unit should be serviced professionally by an authorized MTD Service Dealer.

4. Check brake operation frequently as it is subjected to wear during normal operation. Adjust and service as required.

5. Check the blade(s) and engine mounting bolts at frequent intervals for proper tightness. Also, visually inspect blade(s) for damage (e.g., excessive wear, bent, cracked).

Page 6

Replace the blade(s) with the original equipment manufacturer’s (O.E.M.) blade(s) only, listed in this manual. “Use of parts which do not meet the original equipment specifications may lead to improper performance and compromise safet y!”

6. Mower blades are sharp. Wrap the blade or wear gloves, and use extra caution when servicing them.

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

8. Never tamper with the safety interlock system or other safety devices. Check their proper operat ion regularly.

9. After striking a foreign object, stop the engine, disconnect the spark plug wire(s) and ground against the engine. Thoroughly inspect the machine for any damage. Repair the damage before starting and operating.

10. Never attempt to make adjustments or repairs to the machine while the engine is running.

WARNING: YOUR RESPONSIBILITY- Restrict the use of this power machine to persons who

read, understand and follo w the warnings and instructio ns in this manual and on the mac hine.

11. Grass catcher components and the discharge cover are subject to wear and damage which could expose moving parts or allow objects to be thrown. For safety protection, frequently check components and replace immediately with original equipment manufacturer’s (O.E.M.) parts only, listed in this manual. “Use of parts which do not meet the original equipment specifications may lead to improper performance and compromise safet y!”

12. Do not change the engine governor settings or over-speed the engine. The gover nor controls t he maximum safe operating speed of the engine.

13. Maintain or replace safety and instruction labels, as necessary.

14. Observe proper disposal laws and regulations for gas, oil, etc. to protect the environment.

When stopping the tractor for any reason

Engaging The Cutting Blades

WARNING: Keep feet and hands away

from the discharge opening, the blades or any part of the deck. When the unit is used for anything other than mowing operations, the blade drive should be dise ngaged.

To engage power to the cutting deck or other (separately available) attachment, proceed as follows:

• Move the deck engagement/lift lever to th e right and forward,

• Place the lever a notch for your desired cu tting height.

• Moving the lever to the right and all the way rearward placing it into the BLADES STOP position raises and disengages power to the cutting deck.

NOTE: The deck engagement/lift lever must be in the

disengaged (BLADES STOP) position when starting the engine, when traveling in reverse and if the operator leaves the seat. Refer to Safety Interlock Switches on page 11

Mowing

WARNING: To help avoid blade contact or

a thrown object injury, keep bystanders, helpers, children and pets at least 75 feet from the machine while it is in operation. Stop machine if anyone enters th e area.

The following information will be helpful when using the cutting deck with your tractor.

WARNING: Plan your mowing pattern to

avoid discharge of materials toward roads, sidewalks, bystanders and the like. Also, avoid discharging material against a wall or obstruction which may cause discharged material to ricochet back towar d the operator.

• Be sure that the lawn is clear of st ones, 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.

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

• For best results it is recommended that th e 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.

• Mowing should always be done with the engine at full throttle.

• 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 Cutting Blades on page 19 of this manual for proper blade sharpening instruction s.

SECTION 6: MAKING ADJUSTMENTS

WARNING: Never attempt to make any

adjustments while the engine is running, except where specified in the operator’s manual.

WARNING: Disconnect the spark plug

wire(s) and ground against the engine bef or e performing any adjustments, repairs or maintenance.

Seat Adjustment

To adjust the position of the seat, loosen the two hex screws on the bottom of the seat. See Figure 5. Slide the seat forward or backward as desired. Retighten the two screws.

Hex Screws

• Rotate the blade nearest the discharge chute so that it is parallel with the tractor.

• Measure the distance from the fro nt of the blade tip to the ground and the r ear of the bl ade tip to t he ground. The first measurement taken should be between 1/4" and 3/8" less than the second measurement. Determine the approximat e distance necessary for proper adjustment and proceed, if necessary, to the next step.

• Place the deck engagement/lift lever in the engaged (all the way forward) p osition.

• Remove the hairpin clip from the ferrule fo und at the bottom of the front, left deck link (hairpin clip is on the inside of the lift link). See Figure 6.
