SECTION1: IMPORTANTSAFEOPERATIONPRACTICES

_hb WARNING: This symbol points out important safety instructions which, if not followed, could

endanger the personal safety and/or property of yourself and others. Read and follow all instructionsin this manual before attempting to operate your riding mower. Failure to comply with these instructions may result

in personal injury.When you see thissymbol--heed its warning.

Your riding mower was built to be operated according to the rulesfor safe operation inthis manual. As with any type of power equipment, carelessness or error on the part of the operator can result in serious injury. If you violate any of these rules, you may cause serious injury to yourself or others.

_lb ARNING: Engine exhaust, some of its constituents, and certain vehicle components contain or

emit chemicals known to State of California to cause cancer and birth defects or other

reproductive harm.

GeneralOperation

• Read, understand, and follow all instructions inthe 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 injuryto you or a bystander. To help avoid a thrown objects injury, keep children, bystanders and helpers at least 75 feet from the mower while it isin operation. Always 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 intoreverse 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) removing 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 close- fitting 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 isdesigned 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

onthemowerdeckorcontacttheengineexhaust presentingapotentialfirehazard.

SlopeOperation

• 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 upthe 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. Ifthe slope is greater than 15° as shown on the slope gauge, do not operate this unit in that area or serious injury could result.

Do:

• Mow up and down slopes, not across.

• Remove obstacles such as rocks, limbs, etc.

• 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 manufacturer's 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. Iftires lose traction, disengage the blade(s) and proceed slowly straight down the slope.

DoNot

• 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.

Children

• 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.

Service

• Use extreme care in handling gasoline and other

fuels. They are extremely flammable and the vapors are explosive.

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 accumulate inthe 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.

• Nevertamperwithsafetydevices.Checktheir properoperationregularly.Useallguardsas

SafetyInterlock

This unit is equipped with a safety interlock system for your protection. The interlock safety switches are connected to the brake pedal, the blade engagement 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 riding mower ifthe

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).

• Before leaving operator's position, disengage blade(s), place the shift lever in neutral, engage parking brake, shut engine off and remove key.

UsingShiftLever

The shift lever is used to regulate the direction of your

riding mower. Itcan be set at forward, neutral, or reverse settings. These settings, marked as F, N,and R respectively, are located next to the shift lever on the

unit. See Figure 9.

• Before you move the shift lever to any of the positions, depress the brake pedal and stop the unit. Keep your foot on the brake pedal.

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. Ifit 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.

GrassFillLevelIndicator

This indicator (Figure 10 ) 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 ifyou see the ball in the grass catcher fill level indicator falling down, you should stop the mower

and empty the bag.

To engage the blade lock: While pressing down

on the blade pedal, push the blade lock down with

your heel. It should click into the "blade engaged"

position. To disengage the blade lock, simply push down on the blade pedal and release the lock.

,_ WARNING: When the blades are engaged,

keep hands and feet away from the discharge opening, the blades or any part of the deck.

StoppingMower

• Release blade engagement pedal all the way.

• Release the "Go" Pedal and depress the brake pedal.

• When the mower comes to a complete stop, place

the shift lever in neutral.

• Engage the parking brake by pulling up on the parking brake knob.

• Turn ignition key to OFF position and remove key.

NOTE: Do not leave the key in the ON position when you are not operating the mower. Such action will drain

the battery dead.

ToEmptyGrassCatcher

• Stop the mower completely, pull up on the

parking brake knob and take the ignition key out. Get off the operator's seat.

• Pivot the hood assembly up. Pull up the

grasscatcher bag by the handle and take it to the proper disposal site. See Figure 11 . Hold the bag away from your body. Push down on the bag lever and let the bottom section of

the bag fall downwards. The grass clippings

will be disposed of from the bottom. See Figure 11. Tap the bag on the ground so that the three legs of the bag press against the ground. The bag lever should snap close while you push the bag

downwards. Replace the bag on to the mower making sure

the bag is placed on the flange on top of the

discharge chute. Pivot the hood assembly down.

• 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:

Grass Catcher Bag

Assembly

Figure 11

UsingTheMower

Observe safety rules listed on pages 3-5 of this manual 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 operator's seat.

• 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 riding 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.

SECTION6: MAKINGADJUSTMENTS

,_ WARNING: DO not at any time make any

adjustment to the mower without first stopping engine and disconnecting spark plug wire.

BladeBrake/PTO

The blade engagement pedal should be adjusted so that if you depress it about 3/4" from the front of the slot,

it should start engaging the deck belt. The PTO (power take off) switch is located in the blade brake slot on the

left side of the upper frame. See Figure 13. The brake engagement pedal needs to make contact with the PTO

switch for the engine to start.

Under normal operation, the blade engagement pedal should not require frequent adjustment. However, perform the following test periodically and make sure that it is in fine working condition.

• Pivot the hood assembly up and check if there is

enough slack on the deck engagement cable.

• Depress the blade engagement pedal (about 3/4

inch) and check ifthe belt is engaging.

• If the cable is tight or too loose or the belt is not

engaging, adjust the deck engagement cable.

NOTE: The deck engagement cable will be correctly

adjusted when the cable moves approximately 1/2" off

center line in both directions.

Adjustment to the blade brake will have to be made at the cable end. See Figure 13.

AdjustingtheDeck

There are three tests for checking deck levelling on the riding mower. The results of each test will determine

what kind of levelling, if at all, the equipment needs. IMPORTANT: Perform adjustments to the deck on a flat,

level surface. Before continuing with deck adjustment, check air pressure in all four tires. Recommended air

pressure is 12 psi. Please note that the valve stems on this riding mower are on the inside of the front wheels

and on the outside of the rear wheels.

Test1:CheckingRear DeckHeightAdjustment

• Lift the hood assembly and remove grass catcher

from the riding mower. Place the deck in the highest

position.

• Inspect rear of deck. If the deck is contacting the cable bracket on the front of the transmission, you will have to adjust the rear deck height.

Test2:CheckingFrontto Rear Levelling

• Place the deck in the highest position.

• Wearing a pair of heavy work gloves to prevent injury, rotate the cutting blade so that it is pointed front to back and parallel to the rider. Depress and lock the deck engagement pedal.

• Measure the distance from the front and the rear tips of the blade to the ground.The front should be

approximately 1/4" to 3/8" lower than the rear.

• If the distance is higher, level the deck front to rear.

Test3:CheckingSideto Side Levelling

• Place the deck in the highest position.

• Wearing a pair of heavy work gloves to prevent injury, rotate the cutting blade so that it is pointed

side to side and perpendicular to the rider. Depress and lock the deck engagement pedal.
