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 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 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. 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 tractor to overturn).
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.
4
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 machine.
f.
Disengage the cutting blade(s) before 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 should 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 5 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).
5
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.

Removing Shipping Brace
WARNING:
The shipping brace, used for packaging purposes only, must be removed and discarded before operating your riding mower.
WARNING:
Make sure the riding mower’s engine is off, remove the ignition key, and set the parking brake before removing the shipping brace.
• Locate the shipping brace and accompanying warning tag on the right side of the mower, between the discharge chute and the cutting deck. See
Figure 5.
• While holding the discharge chute with your left hand, remove the shipping brace with your right hand by grasping it between your thumb and index finger and rotating it clockwise.
• Carefully allow the discharge chute to pivot downward.
• Discard the shipping brace and accompanying warning tag.
• 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.
NOTE:
It is not necessary to remove the discharge chute to operate the mower with the mulch kit installed.
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 Figure 6.

Installing The Mulching Plug
(If Equipped)
NOTE:
Your mulching plug may already be installed on the deck.
Some lawn tractors come equipped with a mulch kit which incorporates special blades, already standard on all 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 recommendations for the best results when mulching.
NOTE:
The mulch kit is installed on models equipped with a 39” or 42-inch deck. It is packed separately (with an instruction sheet) in the crate on models equipped
with a 46-inch deck.

Before Starting Engine
WARNING:
Read, understand, and follow all instructions and warnings on the machine and in this manual before operating.
Starting The Engine
IMPORTANT:
This unit is equipped with a safety interlock system for your protection. The purpose of the safety interlock system is to prevent the engine from cranking or starting unless the clutch-brake pedal is depressed and the lift lever is in the BLADES STOP position. In addition, the lift lever must be in the
BLADES STOP position when the unit is put into reverse or the engine will shut off. If the operator leaves the seat with the lift lever engaged and/or without setting the parking brake, the engine will shut off.
• Move throttle control to full throttle to prevent strain on the engine and to operate the cutting blades.
• Place the shift lever in either the FORWARD or
REVERSE position.
• Release the parking brake by depressing the clutch-brake pedal, pressing outward on the speed control lever and moving to desired position. Use first speed position when operating the lawn tractor for the first time.
• Release clutch-brake pedal slowly to put unit into motion.
• The lawn tractor is brought to a stop by depressing the clutch-brake pedal.
WARNING:
Do not operate the tractor if the interlock system is malfunctioning because it is a safety device, designed for protection.
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.
• Place the lift lever in the BLADES STOP position.
• Depress the clutch-brake pedal and set the parking brake.
• Set the throttle control in the FAST position.
• Pull out the choke control (a warm engine may not require choking).
• Turn the ignition key to the right to the START position. After the engine starts, release the key. It will return to the ON position.
Stopping The Engine
Turn the ignition key to the left to the OFF position.
Remove the key to prevent accidental starting.
Be sure that the lawn is clear of stones, 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.
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.
NOTE:
Protect the starter life by using short starting cycles of several seconds. Cranking more than 15 seconds per minute can damage the starter motor.
• Push choke knob in gradually. Move the throttle control to desired engine speed.
WARNING:
If you strike a foreign object, stop the engine, disconnect the spark plug wire(s) and ground against the engine.
Thorougly inspect the machine for any damage. Repair the damage before restarting and operating.
When stopping the unit to empty a grass bag, etc., follow the instructions above. This procedure will also eliminate ‘‘browning’’ the grass, which is caused by hot exhaust gases from a 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.
• Place shift lever in NEUTRAL.
• Restart engine.
• Place speed control lever in high speed position.
• Release clutch-brake pedal fully.
• Depress clutch-brake pedal.

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. MTD shall not be liable for incidental or consequential loss or damages including, without limitation, expenses incurred for substitute or replacement lawn care services, for transportation or for related expenses, or for rental expenses to temporarily replace a warranted
product. (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.
