General Operation
Read, understand, and follow all instructions in the manual and on the machine before starting. Keep this manual in a safe place for future and regular reference and for ordering replacement parts.
Only allow responsible individuals familiar with the instructions to operate the machine. Know controls and how to stop the machine quickly.
Do not put hands or feet under cutting deck or near rotating parts.
Clear the area of objects such as rocks, toys, wire, etc., which could be picked up and thrown by the blade. A small object may have been overlooked and could be accidentally thrown by the mower in any direction and cause injury to you or a bystander. To help avoid a thrown objects injury, keep children, bystanders and helpers at least 75 feet from t he mow er whil e it is in op erati on. Alw ays wear safety glasses or safety goggles during operation or while performing an adjustment or repair, to protect eyes from foreign objects. Stop the blade(s) when crossing gravel drives, walks or roads.
Be sure the area is clear of other people before mowing. Stop machine if anyone enters the area. Never carry passengers.
Disengage blade(s) before shifting into reverse and backing up. Always look down and behind before and while backing.
Be aware of the mower and attachment discharge direction and do not point it at anyone. Do not operate the mower without either the entire grass catcher or the chute guard in place.
Slow down before turning. Operate the machine smoothly. Avoid erratic operation and excessive speed.
Never leave a running machine unattended. Always turn off blade(s), place transmission in neutral, set park brake, stop engine and remove key before dismounting.
Turn off blade(s) when not mowing.
Stop engine and wait until blade(s) comes to a
complete stop before (a) removi ng grass catcher or unclogging chute, or (b) making any repairs, adjusting or removing any grass or debris.
Mow only in daylight or good artificial light.
Do not operate the machine while under the
influence of alcohol or drugs.Watch for traffic when operating near or crossing roadways.
Use extra care when loading or unloading the machine into a trailer or truck. This unit should not be driven up or down a ramp onto a trailer or truck under power, because the unit could tip over, causing serious personal injury. The unit must be pushed manually on a ramp to load or unload properly.
Never make cutting height adjustment while engine is running, if operator must dismount to do so.
Wear sturdy, rough-soled work shoes and close­fitting slacks and shirts. Do not wear loose fitting clothes or jewelry. They can be caught in moving parts. Never operate a unit in bare feet, sandals, or sneakers.
Check overhead clearance carefully before driving under power lines, wires, bridges or low hanging tree branches, before entering or leaving buildings, or in any other situation where the operator may be struck or pulled from the unit, which could result in serious injury.
Disengage all attachment clutches, thoroughly depress the brake pedal, and shift into neutral before attempting to start engine.
Your mower 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. Debris may build up on the mower deck or contact the engine exhaust presenting a potential fire hazard.
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 grea ter t han 1 5° as shown on the slope gauge, do not operate this unit in that area or serious injury could result.
Mow up and down slopes, not across.
Remove obstacle s such a s rocks, limbs, e tc.
Watch for holes, ruts or bumps. Uneven terrain
could overturn the machine. Tall grass can hide obstacles.
Use slow speed. Choose a low enough gear so that you will not have to stop or shift while on the slope. Always keep machine in gear when going down slopes to take advantage of engine braking action.
Follow the manufacturers recommendations for wheel weights or counterweights to improve stability.
Use extra care with grass catchers or other attachments. These can change the stability of the machine.
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.
Avoid starting or stopping on a slope. If tires lose traction, disengage the blade(s) and proceed slowly straight down the slope.
Do Not:
Do not turn on slopes unless necessary; then, turn slowly and gradually downhill, if possible.
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 or ditch, or if an edge caves in.
Do not mow on wet grass. Reduced traction could cause sliding.
Do not try to stabilize the machine by putting your foot on the ground.
Do not use grass catcher on steep slopes.
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. Never assume that children will remain where you last saw them.
Keep children out of the mowing area and in watchful care of an adult other than the operator.
Be alert and turn machine off if children enter the area.
Before and when backing, look behind and down for small children.
Never carry children. They may fall off and be seriously injured or interfere with the safe machine operation.
Never allow children under 14 years old to operate the machine. Children 14 years and over should only operate machine under close parental supervision and proper instruction.
Use extra care when approaching blind corners, shrubs, trees or other objects that may obscure your vision of a child or other hazard.
Remove key when machine is unattended to prevent unauthorized operation.
Use extreme care in handling gasoline and other fuels. They are extremely flammable and the vapors are ex plosiv e. a. Use only an approved container. b. Never remove fuel cap or add fuel with the
engine running. Allow engine to cool at least two minutes before refueling.
c. Replace fuel cap securely and wipe off any
spilled fuel before starting the engine as it may cause a fire or explosion.
d. Extinguish all cigarettes, cigars, pipes and
other sources of ignition.
e. Never refuel the machine indoors because fuel
vapors will accum ulate in the area.
f. Never store the fuel container or machine
inside where there is an open flame or spark, such as a gas hot water heater, space heater or furnace.
Never run a machine inside a closed area.
To reduce fire hazard, keep the machine free of
grass, leaves or other debris build-up. Clean up oil or fuel spillage. Allow machine 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., excessive wear, bent, cracked). Replace with blade which meets original equipment specifications.
Keep all nuts, bolts and screws tight to be sure the equipment is in safe working condition.
Never tamper with safety devices. Check their proper operation regularly. Use all guards as instructed in this manual.
After striking a foreign object, stop the engine, remove the wire from the spark plug and thoroughly inspect the mower for any damage. Repair the damage before restarting and operating the mower.
Grass catcher components are subject to wear, damage and deterioration, which could expose moving parts or allow objects to be thrown. For your safety protection, frequently check components and replace with manufacturers recommended parts when necessary.
Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves and use extra caution when servicing blade(s).
Check brake operation frequently. Adjust and service as required.
Muffler, engine and belt guards become hot during operation and can cause a burn. Allow to cool down before touching.
Do not change the engine governor settings or overspeed the engine. Excessive engine speeds are dangerous.
Observe proper disposal laws and regulations. Improper disposal of fluids and materials can harm the environment and the ecology. a. Prior to disposal, determine the proper method
to dispose of was te from y our local off ice of Environmental Protection Agency. Recycling centers are established to properly dispose of materials in an environmentally safe fashion.
b. Use proper containers when draining fluids. Do
not use food or beverage containers that may mislead someone into drinking from them. Properly dispose of the containers immediately following the draining of fluids.
c. DO NOT pour oil or other fluids into the ground,
down a drain or into a stream, pond, lake or other body of water. Observe Environmental Protection Agency regulations when disposing of oil, fuel, coolant, brake fluid, filters, batteries, tires and other harmful waste.

Safety Interlock
This unit is equipped with a safety interlock system for your protection. The interlock safety switches are connect ed to t he br ake pedal , th e bla de en gagem ent pedal, the shift lever, and the seat.
The purpose of the safety interlock system is threefold:
a. to prevent the engine from starting unless the
brake pedal is depressed and the blade engagement pedal is disengaged;
b. to shut off the engine if the blade pedal is not
disengaged when the shift lever is put into reverse; and
c. to shut the engine off when the operator leaves
the seat without engaging the parking brake.
WARNING: To avoid the risk of serious injury, do not operate the rider mower if the interlock system is malfunctioning.
Remove objects that could be thrown by the blade(s).
Know location and function of all controls.
Be sure blade(s) and engine are stopped before
placing hands or feet near blade(s).

Shift Lever
Figure 9
Move the lever outwards (left) to remove the locking pin from the lever and slide the lever to the position desired. Look at the rear and make sure the path is free of obstacles before positioning the shift lever to the reverse.
Do not force the shift lever. If it does not shift, release the brake pedal slightly to line up the shifting collar in the transmission, then try to move the shift lever.
Slowly release the brake pedal and take your foot off the pedal. Always make sure that there is no one in the way when you run the mower.
Grass Fill Level Indicator
This indicator was designed to add convenience to your riding mower. While the mower is running, air will flow through the discharge chute and into the grass catcher. If the grass catcher is empty, air flows through easily pushing the ball up. If the grass catcher is full, air does not flow through it allowing the ball to fall. So if you see the ball in the grass catcher fill level indicator falling down, you should stop the mower and empty the bag.
Using Throttle/Choke Control
The throttle/choke control is used to increase or decrease the speed of the engine.The FAST and the SLOW positions are marked with illustrations of a rabbit and a turtle respectively. See Figure 9.
For normal operation and when using a grass catcher, move the throttle/choke control to the FAST position.
For maximum charging of the battery and also for a cooler engine while running, move the throttle/ choke control to the FAST position.
For transport and to tow pull-behind attachments, move the throttle/choke control to the SLOW position.
Do not adjust the governor to increase or decrease the engine speed. The governor is set at the factory for maximum engine performance, and should not be altered.
Using Parking Brake

Using The Mower
Observe safet y rules list ed on pages 3- 5 of this ma nual for safe operation of your mower.
Before mowing, make sure that the cutting deck is
leveled. For deck adjustment, refer to page 14.
You can engage the blade by pressing on the blade
engagement pedal with your left foot while sitting on the operators seat.
When mowing an area for the first time, watch out for objects lying on the grass. If you strike a foreign object, stop the engine. Remove wire from spark plug and thoroughly inspect the mower for any damage. Repair the damage before operating it again.
Avoid scalping the lawn by adjusting the cutting height upwards and/or sharpening the blades.
Mow at full throttle. Learn the terrain on which you are mowing. For best mowing results, mow only when the grass is dry.
The recommended mowing pattern is given below:
Mow grass often and in regular intervals so that you
can cut only 1/3 of the grass blade in one mowing.
To empty grass bag, stop the mower completely, engage the parking brake, and turn the ignition off. This will prevent the hot engine exhaust gas from browning the grass.
Many communities no longer haul grass clippings to landfills. Composting the clippings from your grass catcher is a viable solution. For this you will have to empty the grass catcher at the designated composting site.
Your rider mower is equipped with a mulching plug to mulch the grass and recycle into the lawn instead of collecting in the grasscatcher bag.
Mulch only when the grass is dry. Mulching wet grass may damage the underside of the deck because wet grass tends to stick to it. Clean deck thoroughly if you mulch wet grass.
For effective mulching, overlap mowing paths so that the clippings are distributed evenly.
