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 not mow it.
For your safety, use the slope gauge included as part of this manual to measure slopes before operating this machine on a sloped or hilly area. If the slope is greater than 15 degrees as
shown on the slope gauge, do not operate this machine 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 recommendations 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 direction. Rapid engagement or braking could cause the front 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. Over-speeding 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 tractor to overturn).
Section 2 — Important Safe Operation Practices
Children
1.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. 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.
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 blind corners, doorways, shrubs, trees or other objects that may block your vision of a child who may run into the path of the machine.
f.To avoid back-over accidents, always disengage the cutting blade(s) before shifting into Reverse. If equipped, the “Reverse Caution Mode” should not be used when children or others are around.
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.
2.Never allow children under 14 years of age to operate this machine. Children 14 and over should read and understand the instructions and safe operation practices in this manual and on the machine and should be trained and supervised by an adult.
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 machine 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 machine 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.
Section 2 — Important Safe Operation Practices
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). 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 safety!”
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 operation 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.
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 safety!”
12.Do not change the engine governor settings or over-speed the engine. The governor controls the 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.
Do not modify engine
To avoid serious injury or death, do not modify engine in any way. Tampering with the governor setting can lead to a runaway engine and cause it to operate at unsafe speeds. Never tamper with factory setting of engine governor.
Notice Regarding Emissions
Engines which are certified to comply with California and federal EPA emission regulations for SORE (Small Off Road Equipment) are certified to operate on regular unleaded gasoline, and
may include the following emission control systems: Engine Modification (EM) and Three Way Catalyst (TWC) if so equipped.

16 Section 5— Operation
Driving The Tractor
WARNING! Avoid sudden starts, excessive speed and sudden stops.
WARNING! Do not leave the seat of the tractor without first placing the PTO (Blade Engage) lever in the disengaged (OFF) position, depressing the brake pedal and engaging the parking brake. If leaving the tractor unattended, also turn the ignition key off and remove the key.
WARNING! Always look down and behind before and while backing up to avoid a back-over accident.
1.Depress the brake pedal to release the parking brake and let the pedal up.
2.Move the throttle lever into the FAST (rabbit) position.
3.Place the shift lever in either the FORWARD or REVERSE position.
IMPORTANT: Do NOT use the shift lever to change the direction of travel when the tractor is in motion. Always use the brake pedal to bring the tractor to a complete stop before shifting.
4.Release the parking brake by depressing the clutch-brake pedal and positioning the speed control lever in desired position.
IMPORTANT: First-time operators should use speed positions 1 or 2. Become completely familiar with the tractor’s operation and controls before operating the tractor in higher speed positions.
5.Release clutch-brake pedal slowly to put unit into motion.
6.The lawn tractor is brought to a stop by depressing the clutch-brake pedal.
NOTE: When operating the unit initially, there will be little difference between the highest two speeds until after the belts have seated themselves into the pulleys during the break-in period.
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.
IMPORTANT: When stopping the tractor for any reason while on a grass surface, always:
1.Place the shift lever in neutral,
2.Engage the parking brake,
3.Shut engine off and remove the key. Doing so will minimize the possibility of having your lawn ‘‘browned’’ by hot exhaust from your tractor’s running engine.
If unit stalls with speed control in high speed, or if unit will 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 highest speed position.
4.Release clutch-brake pedal fully.
5.Depress clutch-brake pedal.
6.Place speed control lever in desired position.
7.Place shift lever in either FORWARD or REVERSE, and follow normal operating procedures.
Driving On Slopes
Refer to the SLOPE GAUGE in the Important Safe Operation Practices section of the manual to help determine slopes where you may operate the tractor safely.
WARNING! Do not mow on inclines with a slope in excess of 15 degrees (a rise of approximately 2-1/2 feet every 10 feet). The tractor could overturn and cause serious injury.
•Mow up and down slopes, NEVER across.
•Exercise extreme caution when changing direction on slopes.
•Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles.
•Avoid turns when driving on a slope. If a turn must be made, turn down the slope. Turning up a slope greatly increases the chance of a roll over.
•Avoid stopping when driving up a slope. If it is necessary to stop while driving up a slope, start up smoothly and carefully to reduce the possibility of flipping the tractor over backward.
Engaging the Blades
Engaging the PTO (Blade Engage) transfers power to the cutting deck or other (separately available) attachments. To engage the blades, proceed as follows:
1.Move the throttle control lever to the FAST (rabbit) position.
2.Grasp the PTO (Blade Engage) lever and pivot it all the way forward into the engaged (ON) position.
3.Keep the throttle lever in the FAST (rabbit) position for the most efficient use of the cutting deck or other (separately available) attachments.
NOTE: Models with Reverse Caution Mode: The engine will automatically shut off if the PTO is engaged with the shift lever in position for reverse travel with the ignition key in the NORMAL MOWING position.
Models without Reverse Caution Mode:
The PTO (Blade Engage) lever must be in the disengaged (OFF) position when starting the engine, when traveling in reverse, and if the operator leaves the seat. Refer to Safety Interlock Switches in the Operation section of this manual.
Using the Deck Lift Lever
To raise the cutting deck, move the deck lift lever to the left, then place it in the notch best suited for your application. Refer to Setting The Cutting Height earlier in this section.

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 the 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 toward the operator.
•Do not mow at high ground speed, especially if a mulch kit or grass collector is installed.
•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.
•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 in the Service section of this manual for proper blade sharpening instructions.
Mulching
Select models come equipped with a mulch kit which incorporates special blades, already standard on the tractor, in a process of recirculating grass clippings repeatedly beneath the cutting deck. The ultra-fine clippings are then forced back into the lawn where they act as a natural fertilizer.
Observe the following points for the best results when mulching:
•Never attempt to mulch if the lawn is damp. Wet grass tends to stick to the underside of the cutting deck preventing proper mulching of the clippings.
•Do NOT attempt to mulch more than 1/3 the total height of the grass or approximately 1-1/2 inches. Doing so will cause the clippings to clump up beneath the deck and not be mulched effectively.
•Maintain a slow ground speed to allow the grass clippings more time to effectively be mulched.
•Always position the throttle control lever in the FAST (rabbit) position and allow it to remain there while mowing. Failing to keep the engine at full throttle places strain on the tractor’s engine and does not allow the blades to properly mulch grass. Ground speed should be controlled using the speed control lever.
NOTE: It is not necessary to remove the discharge chute to operate the mower with the mulch kit installed.
WARNING! Never operate the mower without the discharge chute properly attached.
To operate the cutting deck without mulching, simply remove the mulch plug by unthreading the plastic wing nut which fastens it to the cutting deck. This will allow the clippings to discharge out the side. See Fig. 5-2.
Figure 5-2
Headlights
•On some models, the lamps are ON whenever the tractor’s engine is running. On other models, the lamps are ON whenever the ignition key is moved into the lights position, with the engine running.
•On all models, the lamps turn OFF when the ignition key is moved to the STOP position.
