safely enough to protect themselves and others

from serious injury.

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).

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. Always use extra caution when towing with a

machine capable of making tight turns (e.g. “zero-

turn” ride-on mower). Make wide turns to avoid

jack-knifing.

6. Travel slowly and allow extra distance to stop.

7. 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 Service Dealer.

4. Check brake operation frequently as it is subjected

to wear during normal operation. Adjust and service

as required.

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.

Systems Indicator Monitor / Hour Meter

LCD

When the ignition key is rotated out of the STOP

position but not into the START position, the systems

indicator monitor displays the battery’s output, in volts,

on its LCD for approximately five seconds, after which it

displays the hours of tractor operation. Once the tractor

is started, the monitor continually displays the hours of

tractor operation on its LCD.

NOTE: Hours of tractor operation are recorded any

time the ignition key is rotated out of the STOP position,

regardless of whether the engine is started.

The Indicator Monitor will also remind the operator of

maintenance intervals for changing the engine oil. The

LCD will alternately flash the recorded hours, “CHG”

and “OIL” for five minutes, after every 50 hours of

recorded operation elapse. The maintenance interval

lasts for two hours (from 50-52, 100-102, 150-152,

etc.). The LCD will also flash as described above for

five minutes every time the tractor’s engine has been

Driving On Slopes

Refer to the SLOPE GAUGE on page 9 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

WARNING: Never engage cruise control

while traveling in Reverse.

1. Slowly press the drive pedal until the desired speed

is achieved.

2. Lightly press the cruise control lever.

3. While continuing to hold the cruise lever down, lift

your foot from the drive pedal (you should feel the

cruise latch engage).

4. Once engaged, the cruise control lever 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 set 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:

• Press the brake pedal to disengage the cruise

control and stop the tractor.

• Lightly press the drive pedal.

To change to the reverse direction when operating with

cruise control, press the brake pedal to disengage the

cruise control and bring the tractor to a complete stop.

Then slowly press the rear portion of the drive pedal

with the ball of your foot to travel in reverse.

Engaging the Parking Brake

To engage the parking brake:

1. Fully press the brake pedal and hold it while gently

pushing the parking brake lever downward.

2. Hold the parking brake lever down while removing

your foot from the brake pedal.

3. Once engaged, the parking brake lever and the

brake pedal will lock in the “down” position.

To disengage the parking brake, slightly press the

brake pedal.

NOTE: The parking brake must be engaged if the

operator leaves the seat with the engine running or the

engine will automatically shut off.

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 to the FAST (rabbit)

position.

2. Grasp the PTO (Blade Engage) lever and pivot it all

the way forward into the engaged (ON) position.

See Figure 11.

Figure 11

3. Keep the throttle/choke control 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 and the ignition key in the NORMAL

MOWING position. Refer to Safety Interlock System on

page 16.

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.

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 throttle

control in the FAST (rabbit) position.

• Under heavy conditions it may be necessary to go

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 on page 23 of this

manual for proper blade sharpening instructions.

SECTION 7: MAKING ADJUSTMENTS

WARNING: Never attempt to make any

adjustments while the engine is running,

Seat Adjustment

To adjust the position of the seat loosen the knob on the

bottom of the seat. See Figure 3. Slide the seat forward

or backward as desired. Retighten the knob.

Leveling the Deck

NOTE: Check the tractor’s tire pressure before

performing any deck leveling adjustments. Refer to

Tires on page 22 for information regarding tire pressure.

Front To Rear

The front of the cutting deck is supported by a stabilizer

bar that can 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. With the tractor parked on a firm, level surface,

place the deck lift lever in the top notch (highest

position) and rotate the blade nearest the discharge

chute so that it is parallel with the tractor.

2. Measure the distance from the front of the blade tip

to the ground and the rear of the blade tip to the

ground.

3. The first measurement taken should be between

1/4" and 3/8" less than the second measurement.

4. Determine the approximate distance necessary for

proper adjustment and proceed, if necessary, to the

next step.

5. From the front of the tractor, loosen the outermost

hex lock nut on the end of the deck hanger rod. See

Figure 12.

6. Tighten the inner hex nut against the front hanger

bracket to raise the front of the deck; loosen the hex

nut to lower the front of the deck. See Figure 12.

7. Retighten the outer lock nut against the inner hex

nut when proper adjustment is achieved.

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.

Figure 12

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 Figure 13.

Figure 13

4. Balance the deck by using a wrench to turn the

adjustment gear (See Figure 13) up or down.

5. The deck is properly balanced when both blade tip

measurements taken earlier are equal.

6. Retighten the hex bolt on the left deck hanger

bracket when proper adjustment is achieved.

!DJUSTMENT'EAR

(EX"OLT

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 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

Figure 14

2. Thread the ball joint clockwise to shorten the drag

link. Thread the ball joint counterclockwise to

lengthen the drag link.

3. Replace hex nut after proper adjustment is

achieved.

NOTE: Threading the ball joints too far onto the drag

links will cause the front tires to "toe-in" too far. Proper

toe-in is between 1/16" and 5/16".

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.

Figure 14

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.

5. Adjust if necessary.

SECTION 8: MAINTAINING YOUR LAWN TRACTOR

NOTE: Refer to Maintenance Chart on page 26 for a

reference of recommended maintenance intervals.

WARNING: Before performing any

maintenance or repairs, disengage PTO, set

parking brake, stop engine and remove key to

prevent unintended starting.

Engine

Refer to the separate engine manual for engine

maintenance instructions.

Check engine oil level before each use as instructed in

the separate engine manual packed with your unit.

Read and follow instructions carefully.

Changing Engine Oil

Draining the Oil

Running the engine for a few minutes to allow the oil in

the crankcase to warm up. Warm oil will flow more

freely and carry away more of the enigne sediment

which may have settled at the bottom of the crankcase.

Use care to avoid burns from hot oil.

• Pop open the protective cap on the end of the oil

drain valve to expose the oil drain port. See Figure

15 .

Figure 15

• Remove the oil fill cap/dipstick from the oil fill tube.

• Push oil drain hose (packed with unit) onto the oil

drain port. Route the opposite end of the hose into

an appropriate oil collection container with a

capacity great enough to collect the used oil.
