SECTION 4: IMPORTANT SAFE OPERATION PRACTICES

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 INSTRUCTIONS IN THIS MANUAL

BEFORE ATTEMPTING TO OPERATE YOUR LAWN MOWER. FAILURE TO COMPLY WITH

THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY. WHEN YOU SEE THIS SYMBOL,

HEED ITS WARNING.

WARNING:

The Engine Exhaust from this product contains chemicals known to

the State of California to cause cancer, birth defects or other reproductive harm.

DANGER: Your lawn mower was built to be operated according to the rules for safe operation in

this manual. As with any type of power equipment, carelessness or error on the part of the operator

can result in serious injury. This lawn mower is capable of amputating hands and feet and throwing

objects. Failure to observe the following safety instructions could result in serious injury or death.

1. GENERAL OPERATION

• Read, understand, and follow all instructions in the

• 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.

operator’s manual and on the machine before

starting. Keep this manual in a safe place for future

and regular reference and for ordering replacement

parts.

• Turn off blade(s) when not mowing.

• Only allow responsible individuals familiar with the

instructions to operate the machine. Know controls

and how to stop the machine quickly.

• 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.

• Do not put hands or feet under cutting deck or near

rotating parts.

• Mow only in daylight or good artificial light.

• 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 the mower while it is in 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.

• 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 a cutting height adjustment while

engine is running if operator must dismount to do

so.

• Be sure the area is clear of other people before

mowing. Stop machine if anyone enters the area.

• Never carry passengers.

• 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.

• 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.

• 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.

• Slow down before turning. Operate the machine

smoothly. Avoid erratic operation and excessive

speed.

• Disengage all attachment clutches, thoroughly

depress the brake pedal, and shift into neutral

before attempting to start engine.

3. 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 chil-

dren will remain where you last saw them.

• 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.

• 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

2. SLOPE OPERATION

for small children.

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.

• Never carry children, even with the blades off. They

may fall off and be seriously injured or interfere with

the safe machine operation.

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° as

shown on the slope gauge, do not operate this unit on that

area or serious injury could result.

• 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.

• Remove key when machine is unattended to

prevent unauthorized operation.

DO:

• Use extra care when approaching blind corners,

shrubs, trees or other objects that may obscure

your vision of a child or other hazard.

• 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.

4. SERVICE

• Use extreme care in handling gasoline and other

fuels. They are extremely flammable and the

vapors are explosive.

• Use slow speed. Always keep machine in gear

when going down slopes to take advantage of

engine braking action.

• Use only an approved container.

• Never remove fuel cap or add fuel with the engine

running. Allow engine to cool at least two minutes

before refueling.

• Follow the manufacturer’s recommendations for

wheel weights or counterweights to improve

stability.

• Replace fuel cap securely and wipe off any spilled

fuel before starting the engine as it may cause a

fire or explosion.

• Use extra care with grass catchers or other

attachments. These can change the stability of the

machine.

• Extinguish all cigarettes, cigars, pipes and other

• 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.

sources of ignition.

• Never refuel the machine indoors because fuel

vapors will accumulate in the area.

• 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.

• Avoid starting or stopping on a slope. If tires lose

traction, disengage the blade(s) and proceed slowly

straight down the slope.

• 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.

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.

• 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.

• Do not mow on wet grass. Reduced traction could

cause sliding.

• 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.

• Do not try to stabilize the machine by putting your

foot on the ground.

• Do not use grass catcher on steep slopes.

application. Refer to SETTING THE CUTTING

HEIGHT earlier in this section.

ENGAGING THE PTO

(POWER TAKE-OFF) LEVER

WARNING: Never direct the discharge

of material toward bystanders or allow

anyone near the machine while in

operation.

• Move the throttle control lever to the FAST

(rabbit) position.

• 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.

• Move the PTO lever forward into the engaged

(ON) position.

• Keep the throttle lever in the FAST (rabbit)

position for the most efficient use of the

cutting deck and other attachments.

• The operator must remain in the tractor seat

at all times. If the operator should leave the

seat without moving the PTO lever into the

disengaged (OFF) position and setting the

parking brake, the engine will shut off.

• 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.

IMPORTANT: The PTO lever cannot be in the

engaged (ON) position when the tractor is driving in

the reverse direction. The safety interlock system will

Sharpen Edge Evenly

Figure 20

Download from Www.Somanuals.com. All Manuals Search And Download.

It is extremely important that each cutting blade

edge be ground equally to maintain proper blade

balance. An unbalanced blade will cause excessive

vibration when rotating at high speeds, may cause

damage to the tractor and result in personal injury.

The blade can be tested by balancing it on a blade

balancer or round shaft screwdriver. Grind metal

from the heavy side until it balances evenly.

IMPORTANT: If removing the battery for any

reason, disconnect the NEGATIVE (Black) wire from

it’s terminal first, followed by the POSITIVE (Red)

wire. When re-installing the battery, always connect

the POSITIVE (Red) wire its terminal first, followed

by the NEGATIVE (Black) wire. Be certain that the

wires are connected to the correct terminals,

reversing them could change the polarity and cause

damage to your engine’s alternating system.

When replacing the blade, be sure to install the

blade with the side of the blade marked ‘‘Bottom’’ (or

with a part number stamped in it) facing the ground

when the mower is in the operating position.

Charging

If the unit has not been put into use for an extended

period of time, charge the battery with an

automotive-type 12-volt charger for a minimum of

one hour at six amps.

IMPORTANT: Use a torque wrench to tighten the

blade spindle hex flange nut to between 70 foot-

pounds and 90 foot-pounds.

WARNING: Batteries give off an

explosive gas during and for some time

after charging. Charge battery in a well

ventilated area and do not allow a spark or

an open flame near the battery.

TIRES

The recommended operating tire pressure is

approximately 10 psi for the rear tires and 14 psi for

the front tires. Refer to the tire sidewall for exact tire

manufacturer’s

overinflate. Uneven tire pressure could cause the

cutting deck to mow unevenly.

FUSE

A fuse is installed in your tractor’s wiring harness to

protect the tractor’s electrical system from damage

caused by excessive amperage. Always use the

same capacity fuse for replacement. If the electrical

system does not function, or your tractor’s engine

will not crank, first check to be certain that the fuse

has not blown. It can be found under the hood

mounted behind the top of dash panel on the

support bar. Pull the fuse out and compare it with

Figure 21 to determine if it is good or bad.

BATTERY

The battery is sealed and is maintenance-free. Acid

levels cannot be checked.
