10.Be aware of the mower and attachment discharge direction and do not point it at anyone. Do not operate the mower without the discharge cover or entire grass catcher in its proper place.
11.Do not put hands or feet near rotating parts or under the cutting deck. Contact with the blade(s) can amputate hands and feet.
12.A missing or damaged discharge cover can cause blade contact or thrown object injuries.
13.Stop the blade(s) when crossing gravel drives, walks, or roads and while not cutting grass.
14.Watch for traffic when operating near or crossing roadways. This machine is not intended for use on any public roadway.
15.Do not operate the machine while under the influence of alcohol or drugs.
16.Mow only in daylight or good artificial light.
17.Never carry passengers.
18.Disengage blade(s) before shifting into reverse. Back up slowly. Always look down and behind before and while backing to avoid a back-over accident.
19.Slow down before turning. Operate the machine smoothly. Avoid erratic operation and excessive speed.
20.Disengage blade(s), set parking brake, stop engine and wait until the blade(s) come to a complete stop before removing grass catcher, emptying grass, unclogging chute, removing any grass or debris, or making any adjustments.
21.Never leave a running machine unattended. Always turn off blade(s), place transmission in neutral, set parking brake, stop engine and remove key before dismounting.
22.Use extra care when loading or unloading the machine into a trailer or truck. This machine should not be driven up or down ramp(s), because the machine could tip over, causing serious personal injury. The machine must be pushed manually on ramp(s) to load or unload properly.
23.Muffler and engine become hot and can cause a burn. Do not touch.
24.Check overhead clearances carefully before driving under low hanging tree branches, wires, door openings etc., where the operator may be struck or pulled from the machine, which could result in serious injury.
25.Disengage all attachment clutches, depress the brake pedal completely and shift into neutral before attempting to start engine.
26.Your machine 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.

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.
Spark Arrestor
Warning: This machine is equipped with an internal combustion engine and should not be used on or near any unimproved forest-covered, brushcovered or grass-covered land unless the engine’s exhaust system is equipped with a spark arrester meeting applicable local or state laws (if any).

Operation
Safety Interlock Switches
This tractor is equipped with a safety interlock system for the protection of the operator. If the interlock system should ever malfunction, do not operate the tractor. Contact an authorized Troy-Bilt service dealer.
•The safety interlock system prevents the engine from cranking or starting unless the parking brake is engaged, and the PTO (Blade Engage) lever is in the disengaged (OFF) position.
•The engine will automatically shut off if the operator leaves the seat before engaging the parking brake.
PTO (Blade Engage)
•The engine will automatically shut off if the operator leaves the tractor’s seat with the PTO (Blade Engage) lever in the engaged (ON) position, regardless of whether the parking brake is engaged.
•With the ignition key in the NORMAL MOWING position, the engine will automatically shut off if the PTO (Blade Engage) lever is moved into the engaged (ON) position with the shift lever in Reverse.

Engaging the Parking Brake
To engage the parking brake:
1.Fully depress the brake pedal and hold it down with your foot while gently pushing the parking brake button inward.
2.Hold the parking brake button in while removing your foot from the brake pedal.
3.Once engaged, the parking brake button and the brake pedal will lock in the “down” position.
To disengage the parking brake:
1.Slightly depress the brake pedal.
NOTE: The parking brake must be engaged if the operator leaves the seat with the engine running or engine will automatically shut off.
Setting the Cutting Height
1.Select the height position of the cutting deck by placing the deck lift lever in any of the six different cutting height notches on the right side of the fender.
2.Adjust the deck wheels so that they are between ¼-inch and ½-inch above the ground when the tractor is on a smooth, flat surface such as a driveway.
WARNING: Keep hands and feet away from the discharge opening of the cutting deck.
NOTE: The deck wheels are an anti-scalp feature of the deck and are not designed to support the weight of the cutting deck.
Refer to Leveling the Deck in the Maintenance & Adjustments section of this manual for more detailed instructions regarding various deck adjustments.
Starting the Engine
WARNING: Do not operate the tractor if the interlock system is malfunctioning. This system was
designed for your safety and protection.
IMPORTANT: Your tractor is shipped with motor oil in the engine. However, you MUST check the oil level before operating. Be careful not to overfill. Refer to the Engine Operator’s Manual included with your lawn tractor for complete Gasoline and Oil fill-up instructions.
1.Insert the tractor key into the ignition switch.
2.Place the PTO (Blade Engage) lever in the disengaged (OFF) position.
3.Engage the tractor’s parking brake.
4.Activate the choke control.
5.Turn the ignition key clockwise to the START position. After the engine starts, release the key. It will return to the ON position.
14
IMPORTANT: Do NOT hold the key in the START position for longer than ten seconds at a time. Doing so may cause damage to your engine’s electric starter.
6.After the engine starts, deactivate the choke control and place the throttle control in the FAST position.
NOTE: Do NOT leave the choke control on while operating the tractor. Doing so will result in a “rich” fuel mixture and cause the engine to run poorly.
Stopping the Engine
WARNING: If you strike 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 restarting and operating.
1.If the blades are engaged, place the PTO (Blade Engage) lever in the disengaged (OFF) position.
2.Turn the ignition key counterclockwise to the STOP position.
3.Remove the key from the ignition switch to prevent unintended starting.
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.
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.
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.
1.To move forward, place the shift lever in the FORWARD position, then slowly depress the drive pedal until the desired speed is achieved.
2.To move in reverse, place the shift lever in the REVERSE position, check that the area behind is clear then slowly depress the drive pedal.
Driving On Slopes
Refer to the SLOPE GAUGE in the Important Safe Operation Practices section of this 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.
Setting The Cruise Control
1.Place the shift lever in the FORWARD position, then slowly depress the drive pedal until the desired speed is achieved.
2.Lightly depress the cruise control button.
3.While continuing to hold the cruise button in, lift your foot from the drive pedal (you should feel the cruise latch engage).
Once engaged, the cruise control button and the drive pedal will lock in the “down” position, and the tractor will maintain the same forward speed.
NOTE: Cruise control can not be engaged at the tractor’s fastest ground speed. If the operator should attempt to do so, the tractor will automatically decelerate to the fastest optimal mowing ground speed.
Disengage the cruise control using one of the following methods:
1.Depress the brake pedal to disengage the cruise control and stop the tractor.
2.Lightly depress the drive pedal.
To change to the reverse direction when operating with cruise control, depress the brake pedal to disengage the cruise control and bring the tractor to a complete stop. Then place the shift lever in the REVERSE position and depress the drive pedal.

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
IMPORTANT: 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. Refer to Safety Interlock Switches earlier in this section.
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 Maintaining Your Lawn Tractor section of this manual for proper blade sharpening instructions.
Headlights
•The lamps are ON whenever the ignition key is moved out of the STOP position.
•The lamps turn OFF when the ignition key is moved to the STOP position.

Adjustments
WARNING! Shut the engine off, remove the ignition key and engage the parking brake before making adjustments. Protect your hands by using heavy gloves when handling the blades.
NOTE: Check the tractor’s tire pressure before performing any deck leveling adjustments. Refer to Tires in the Service section for information regarding tire pressure.
Leveling the Deck (Front To Rear)
The front of the cutting deck is supported by a stabilizer bar that can be adjusted to level the deck from front to rear. The front of the deck should be between 1⁄4-inch and 3⁄8-inch lower than the rear of the deck. Adjust if necessary as follows:
1.Park the tractor parked on a firm, level surface and place the deck lift lever in the top notch.
2.Rotate the blade nearest the discharge chute so that it is parallel with the tractor.
3.Measure the distance from the front of the blade tip to the ground and the rear of the blade tip to the ground. The first measurement taken should be between 1⁄4-inch and 3⁄8-inch less than the second measurement.
Determine the approximate distance necessary for proper adjustment and proceed, if necessary.
1.Loosen (thread outward) the hex lock nut on the end of the deck hanger rod. See Fig. 6-4.
Figure 6-4
2.To raise the front of the deck, tighten (thread inward) the inner hex nut against the front hanger bracket.
To lower the front of the deck, loosen (thread outward) the hex nut, away from the front hanger bracket.
See Fig. 6-4.
3.Retighten the lock nut against each hex nut when proper adjustment is achieved.
Leveling the Deck (Side to Side)
If the cutting deck appears to be mowing unevenly, a side to side adjustment can be performed. Adjust if necessary as follows:
1.With the tractor parked on a firm, level surface, place the deck lift lever in the top notch (highest position) and rotate both blades so that they are perpendicular with the tractor.
2.Measure the distance from the outside of the left blade tip to the ground and the distance from the outside of the right blade tip to the ground. Both measurements taken should be equal. If they’re not, proceed to the next step.
3.Loosen, but do NOT remove, the hex bolt on the left deck hanger bracket. See Fig. 6-5.

Parking Brake Adjustment
WARNING: Never attempt to adjust the brakes while the engine is running. Always disengage PTO, move shift lever into neutral position, stop engine and remove key to prevent unintended starting.
If the tractor does not come to a complete stop when the brake pedal is completely depressed, or if the tractor’s rear wheels can roll with the parking brake applied, the brake is in need of adjustment. See your authorized Troy-Bilt service dealer to have the brake properly adjusted.
Adjusting the Seat
Refer to the Set-Up and Assembly section of this manual for seat adjustment instructions.
Steering Adjustment
If the tractor turns tighter in one direction than the other, or if the ball joints are being replaced due to damage or wear, the steering drag links may need to be adjusted.
Adjust the drag links so that equal lengths of each are threaded into the ball joint on the left side and the ball joint on the right side:
1.Remove the hex nut on the top of ball joint. See Fig. 6-6.
Front tire toe-in can be measured as follows:
1.Place the steering wheel in position for straight ahead travel.
2.In front of the axle, measure the distance horizontally from the inside of the left rim to the inside of the right rim. Note the distance.
3.Behind the axle, measure the distance horizontally from the inside of the left rim to the inside of the right rim. Note the distance.
4.The measurement taken in front of the axle should be between 1⁄16” and 5⁄16” less than the measurement taken behind the axle.
Hex Nut
