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
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.

• 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 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.

• 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) 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 a 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.

3

• 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.

2. 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° as

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

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.

• 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, even with the blades off. 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.

• Remove key when machine is unattended to
prevent unauthorized operation.

• Use extra care when approaching blind corners,
shrubs, trees or other objects that may obscure

your vision of a child or other hazard.

4. SERVICE

• Use extreme care in handling gasoline and other
fuels. They are extremely flammable and the
vapors are explosive.

• 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.

• Replace fuel cap securely and wipe off any spilled

fuel before starting the engine as it may cause a
fire or explosion.

• Extinguish all cigarettes, cigars, pipes and other
sources of ignition.

• Never refuel the machine indoors because fuel
vaporswillaccumulate inthe 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.

• 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.

4

• 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 manufacturer's
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.

Prior to disposal, determine the proper method to
dispose of waste from your local Environmental
Protection Agency. Recycling centers are
established to properly dispose of materials in an
environmentally safe fashion.

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.

DO NOT pour oil or other fluids into the ground,
clown 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.

DRIVING ON SLOPES

Refer to the SLOPE GAUGE on page 6 to help
determine slopes where you may not operate 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.

Operate the tractor up and down slopes, never
across slopes. Do not drive so that the tractor may
tip over sideways.
Before operating the tractor on any slope, walk the
slope to look for possible hazards such as rocks.
mounds, ruts, stumps or other surface irregularities
which could cause the tractor to be upset.
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.

OPERATING THE HEADLIGHTS

To turn the tractor's headlights on:

• Start the engine following the instructions
earlier in this section.

• Turn the key one notch counterclockwise into
the On/Lights position of the ignition switch.

Refer to Figure 4.

To turn the tractor's headlights off:

• Turn the key either into the On position (to
leave the engine running) or the Off position
(to shut the engine off). Refer to Figure 4.

IMPORTANT: Never move the key into the Start

position while the engine is running. Doing so may
cause damage to your engine's starter.

STOPPING THE ENGINE

• Place the PTO switch in the disengaged

(OFF) position.

• Move the throttle control into the SLOW
position and allow the engine to "idle down"

for ten seconds, then turn the ignition key
counterclockwise to the OFF position.

• Remove the key from the ignition switch to
prevent accidental starting.

IMPORTANT: If you think you've struck a foreign

object, stop the engine immediately. Remove the

wire(s) from the spark plug(s), thoroughly inspect the
unit for any damage, and repair the damage before
restarting and operating the mower.

USING THE LIFT LEVER

To raise the cutting deck, move the 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.

disengaged (OFF) position when the shift/ever is in

REVERSE or the PTO will automatically shut off.
Refer to SAFETY INTERLOCK SWITCHES in this

section.

MOWING

This tractor is equipped with one of MTLTs high
quality cutting decks. The following information will
be helpful when using the cutting deck with your

tractor.

WARNING: To avoid possible injury, do

not allow anyone in the area of the tractor
while mowing. Even if the area to be

mowed has been cleared of foreign
objects, small objects may be picked up
and discharged by the mower,

WARNING: Never direct the discharge

of material toward bystanders or allow

anyone near the machine while in

operation.

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.

• Do not mow at high ground speed, especially

if a mulch kit or grass collector is installed.

• 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 the MAINTENANCE

section of this manual for proper blade
sharpening instructions.

SECTION 9: ADJUSTMENTS

LEVELING THE DECK

_, WARNING: Cutting blades are sharp.

Always protect hands by wearing heavy

leather work gloves to grasp blades.

NOTE: Check the tractor's tire pressure before

performing any deck leveling adjustments. Refer to

TIRES in the maintenance section of this rnanua/ for

further information regarding tire pressure.

Front to Rear

The front of the cutting deck is supported by a stabi-

lizer bar that can adjusted to level the deck from front

to rear. The front of the deck should be 1/4" to 3/8"

lower than the rear of the deck. Adjust if necessary
as follows:

WARNING: Turn the tractor's engine
off, remove the key from the ignition switch

and apply the tractor's parking brake before
making any adjustments to the cutting

deck.

• With the tractor parked on a firm, level

surface, place the lift lever in the top notch
(highest position) and rotate the blade nearest

the discharge chute so that it is parallel with
the tractor.

• 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" and 3/8" less
than the second measurement. Determine the

approximate distance necessary for proper
adjustment and proceed, if necessary, to the
next step.

• Loosen the two jam nuts on the rear side of
the deck stabilizer bracket. See Figure 8A.

• Locate the two lock nuts on the opposite side
of the stabilizer bracket. See Figure 8A.
Tighten the lock nuts to raise the front of the

deck; loosen the lock nuts to lower the front of
the deck.

• Retighten the two jam nuts loosened earlier

when proper adjustment is achieved.

14

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:

,_ WARNING: Turn the tractor's engine off, remove the key from the ignition switch and apply the

tractor's parking brake before making any adjustments to the cutting deck.

• With the tractor parked on a firm, level surface, place the lift lever in the top notch (highest position) and
rotate the both blades so that they are perpendicular with the tractor.

• 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.

• Loosen, but do NOT remove, the hex cap screw on the left deck hanger bracket. See Figure 8B.

• Balance the deck so that both blade tip measurements taken earlier are equal.

CUTTING BLADES

WARNING: Cutting blades are sharp.

Always protect hands by wearing heavy
leather work gloves to grasp blades.

The blades may be removed for sharpening or
replacement as follows.

• Remove the deck from beneath the tractor,
(refer to DECK REMOVAL earlier in this

section for detailed instructions) then gently
flip the deck over to expose its underside.

• Place a block of wood between the center
deck housing baffle and the cutting blade to

act as a stabilizer. See Figure 20.

• Use a 15/16" wrench to remove the hex flange
nut that secures the blade to the spindle

assembly. See Figure 20.

NOTE: The hex flange nut has a right-handed

thread pattern. Do NOT attempt to force the nut in
the incorrect direction. Doing so may damage the

nut and create a safety hazard.

Figure 20

To properly sharpen the cutting blades, remove
equal amounts of metal from both ends of the blades

along the cutting edges. See Figure 21.
Sharpen the cutting edge straight across, parallel to

the trailing edge, at a 25° to 30° angle. See Figure

21.

IMPORTANT: If the cutting edge of the blade has

already been sharpened to within 5/8" of the wind
wing radius, or if any metal separation is present,
replace the blades with new ones. See Figure 21.

Worn Blade Edge

Blade Separation Wind Wing

Figure 21

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 round

shaft screwdriver. Grind metal from the heavy side

until it balances evenly.

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.

IMPORTANT: use a torque wrench to tighten the

blade spindle hex flange nut to between 70 foot-

pounds and 90 foot-pounds.

BATTERY

The battery is sealed and is maintenance-free. Acid

levels cannot be checked.

• Always keep the battery cables and terminals
clean and free of corrosive build-up.

• After cleaning the battery and terminals, apply
a light coat of petroleum jelly or grease to the

terminals and over the positive terminal boot.

• Always keep the boot positioned over the
positive terminal to prevent shorting.

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 NEGATIVE (Black) wire its terminal first, followed

by the POSITIVE (Red) 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.

22

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.

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 recommended psi. Do not
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 22 to determine if it is good or bad.
