ONLY RIDE UP AND DOWN HILL, NOT ACROSS HILL
SUGGESTED GUIDE FOR SIGHTING SLOPES FOR SAFE OPERATION
WARNING: To avoid serious injury, operate your tractor up and down the face of slopes, never across the face. Do not mow slopes greater than 15 degrees. Make turns gradually to prevent tipping or loss of control. Exercise extreme caution when changing direction on slopes.
1. Fold this page along dotted line indicated above. 2. Hold page before you so that its left edge is vertically parallel to a tree trunk or other upright structure. 3. Sight across the fold in the direction of hill slope you want to measure. 4. Compare the angle of the fold with the slope of the hill.

SAFETY RULES
I. GENERAL OPERATION
• Read, understand, and follow all instruc-
tions in the manual and on the machine
before starting.
• Only allow responsible adults, who are
familiar with the instructions, to operate
the machine.
• Clear the area of objects such as rocks,
toys, wire, etc., which could be picked
up and thrown by the blade.
• Be sure the area is clear of other people
before mowing. Stop machine if anyone
enters the area.
• Never carry passengers.
• Do not mow in reverse unless abso-
lutely necessary. Always look down and
behind before and while backing.
• Be aware of the mower discharge direc-
tion and do not point it at anyone. Do
not operate the mower without either
the entire grass catcher or the guard in
place.
• Slow down before turning.
• Never leave a running machine unat-
tended. Always turn off blades, set
parking brake, stop engine, and remove
keys before dismounting.
• Turn off blades when not mowing.
• Stop engine before removing grass
catcher or unclogging chute.
• 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 un-
loading the machine into a trailer or
truck.
• Data indicates that operators, age 60
years and above, are involved in a large
percentage of riding mower-related in-
juries. These operators should evaluate
their ability to operate the riding mower
safely enough to protect themselves and
others from serious injury.
• Keep machine free of grass , leaves or
other debris build-up which can touch
hot exhaust / engine parts and burn . Do
not allow the mower deck to plow leaves
or other debris which can cause build-
up to occur. Clean any oil or fuel
spillage before operating or storing the
machine . Allow machine to cool before
storage.
II. SLOPE OPERATION
Slopes are a major factor related to loss-
of-control and tipover 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.
IMPORTANT: This cutting machine is capable of amputating hands and feet and throw-
ing objects. Failure to observe the following safety instructions could result in serious
injury or death.
WARNING: In order to prevent ac-
cidental starting when setting up, trans-
porting, adjusting or making repairs,
always disconnect spark plug wire and
place wire where it cannot contact spark
plug.
WARNING: Do not coast down a hill in
neutral, you may lose control of the tractor.
WARNING: Tow only the attachments
that are recommended by and comply with
specifi cations of the manufacturer of your
tractor. Use common sense when towing.
Operate only at the lowest possible speed
when on a slope. Too heavy of a load,
while on a slope, is dangerous. Tires can
lose traction with the ground and cause
you to lose control of your tractor.
WARNING: Engine exhaust, some of
its constituents, and certain vehicle com-
ponents contain or emit chemicals known
to the State of California to cause cancer
and birth defects or other reproductive
harm.
WARNING: Battery posts, terminals
and related accessories contain lead and
lead compounds, chemicals known to the
State of California to cause cancer and
birth defects or other reproductive harm.
Wash hands after handling.

SAFETY RULES
DO:
• Mow up and down slopes, not across.
• Remove obstacles such as rocks, tree
limbs, etc.
• Watch for holes, ruts, or bumps. Un-
even terrain could overturn the machine.
Tall grass can hide obstacles.
• Use slow speed. Choose a low gear
so that you will not have to stop or shift
while on the slope.
• Follow the manufacturer’s recommend-
ations for wheel weights or counter-
weights 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.
• Avoid starting or stopping on a slope. If
tires lose traction, disengage the blades
and proceed slowly
straight down the
slope.
DO NOT:
•
Do not turn on slopes unless neces-
sary, and 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.
III. CHILDREN
Tragic accidents can occur if the operator
is not alert to the presence of children.
Children are often attracted to the ma-
chine and the mowing activity.
Never as-
sume that children will remain where you
last saw them.
• Keep children out of the mowing area
and under the watchful care of another
responsible adult.
• 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
safe machine operation.
• Never allow children to operate the
machine.
• Use extra care when approaching blind
corners, shrubs, trees, or other objects
that may obscure vision.
IV. SERVICE
• Use extra care in handling gasoline and
other fuels. They are flammable and
vapors are explosive.
- Use only an approved container.
- Never remove gas cap or add fuel
with the engine running. Allow
engine to cool before refueling. Do
not smoke.
- Never refuel the machine indoors.
- Never store the machine or fuel
container inside where there is an
open flame, such as a water heater.
• Never run a machine inside a closed
area.
• Keep nuts and bolts, especially blade
attachment bolts, tight and keep equip-
ment in good condition.
• Never tamper with safety devices.
Check their proper operation regularly.
• Keep machine free of grass, leaves, or
other debris build-up. Clean oil or fuel
spillage. Allow machine to cool before
storing.
• Stop and inspect the equipment if you
strike an object. Repair, if necessary,
before restarting.
• Never make adjustments or repairs with
the engine running.
• Grass catcher components are subject
to wear, damage, and deterioration,
which could expose moving parts or
allow objects to be thrown. 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 them.
• Check brake operation frequently. Ad-
just and service as required.

• Do not mow in reverse unless abso-
lutely necessary. Always look down and
behind before and while backing.
• Never carry children. They may fall off
and be seriously injured or interfere with
safe machine operation.
• Keep children out of the mowing area
and under the watchful care of another
responsible adult.
• Be alert and turn machine off if children

The operation of any tractor can result in foreign objects thrown into
the eyes, which can result in severe eye damage. Always wear safety
glasses or eye shields while operating your tractor or performing any
adjustments or repairs. We recommend a wide vision safety mask over
spectacles or standard safety glasses.

TO USE THROTTLE CONTROL
Always operate engine at full throttle.
• Operating engine at less than full
throttle reduces the battery charging
rate.
• Full throttle offers the best bagging and
mower performance.
HOW TO USE YOUR TRACTOR
TO SET PARKING BRAKE
Your tractor is equipped with an operator
presence sensing switch. When engine
is running, any attempt by the operator
to leave the seat without first setting the
parking brake will shut off the engine.
1. Depress clutch/brake pedal all the way
down and hold.
2. Pull parking brake lever up and release
pressure from clutch/brake pedal.
Pedal should remain in brake position.
Make sure parking brake will hold trac-
tor secure.
TO MOVE FORWARD AND BACKWARD
The direction and speed of movement is
controlled by the gearshift lever.
1. Start tractor with clutch/brake pedal de-
pressed and gearshift lever in neutral
(N) position.
2. Move gearshift lever to desired po-
sition.
3. Slowly release clutch/brake pedal to
start movement.
IMPORTANT: Bring tractor to a complete
stop before shifting or changing gears.
Failure to do so will shorten the useful life
of your transaxle.
TO ADJUST MOWER CUTTING HEIGHT
The position of the attachment lift lever
determines the cutting height.
• Grasp lift lever.
• Press plunger with thumb and move
lever to desired position.
The cutting height range is approxi-
mately 1-1/2 to 4". The heights are mea-
sured from the ground to the blade tip with
the engine not running. These heights
are approximate and may vary depending
upon soil conditions, height of grass and
types of grass being mowed.
• The average lawn should be cut to approxi-
mately 2-1/2 inches during the cool season
and to over 3 inches during hot months.
For healthier and better looking lawns, mow
often and after moderate growth.

GROUND DRIVE -
• To stop ground drive, depress clutch/
brake pedal all the way down.
• Move gearshift lever to neutral (N)
position.
ENGINE -
• Move throttle control to slow position.
NOTE: Failure to move throttle control to
slow position to allow engine to idle before
stopping may cause engine to “backfire”.
• Turn ignition key to “STOP” position and
remove key. Always remove key when
leaving tractor to prevent unauthorized
use.
• Never use choke to stop engine.
IMPORTANT: Leaving the ignition switch
in any position other than "STOP" will
cause the battery to discharge and go
dead.
NOTE: Under certain conditions when
tractor is standing idle with the engine
running, hot engine exhaust gases may
cause “browning” of grass. To eliminate
this possibility, always stop engine when
stopping tractor on grass areas.
CAUTION: Always stop tractor com-
pletely, as described above, before leaving
the operator's position.

TO TRANSPORT
• Raise attachment lift to highest position
with attachment lift control.
• When pushing or towing your tractor,
be sure gearshift lever is in neutral (N)
position.
• Do not push or tow tractor at more than
five (5) MPH.
NOTE: To protect hood from damage
when transporting your tractor on a truck
or a trailer, be sure hood is closed and
secured to tractor. Use an appropriate
means of tying hood to tractor (rope, cord,
etc.).
TO OPERATE ON HILLS
WARNING: Do not drive up or down
hills with slopes greater than 15° and do
not drive across any slope. Use the slope
guide at the back of this manual.
• Choose the slowest speed before start-
ing up or down hills.
• Avoid stopping or changing speed on
hills.
• If slowing is necessary, move throttle
control lever to slower position.
• If stopping is absolutely necessary, push
clutch/brake pedal quickly to brake posi-
tion and engage parking brake.
• Move gearshift lever to 1st gear. Be
sure you have allowed room for tractor
to roll slightly as you restart movement.
• To restart movement, slowly release
parking brake and clutch/brake pedal.
• Make all turns slowly.
• For best cutting performance, grass over
6 inches in height should be mowed
twice. Make the first cut relatively high;
the second to desired height.
TO OPERATE MOWER
Your tractor is equipped with an operator
presence sensing switch. Any attempt
by the operator to leave the seat with the
engine running and the attachment clutch
engaged will shut off the engine.You must
remain fully and centrally positioned in the
seat to prevent the engine from hesitating
or cutting off when operating your equip-
ment on rough, rolling terrain or hills.
1. Select desired height of cut.
2. Start mower blades by engaging at-
tachment clutch control.

TO ADJUST GAUGE WHEELS
Gauge wheels are properly adjusted
when they are slightly off the ground when
mower is at the desired cutting height in
operating position. Gauge wheels then
keep the deck in proper position to help
prevent scalping in most terrain conditions.
NOTE: Be sure tractor is on a flat level
surface.
1. Lower mower and adjust mower to de-
sired cutting height(See “TO ADJUST
MOWER CUTTING HEIGHT” in this
section of manual).
2. Remove retainer spring and clevis pin
which secure each gauge wheel bar.
3. Lower gauge wheels to ground. Raise
gauge wheels slightly to align holes
in bracket and gauge wheel bar and
insert clevis pin. Gauge wheels should
be slightly off the ground.
4. Replace retainer spring into clevis pin.
5. Be sure all gauge wheels are in the
same setting.
IMPORTANT: Be sure to readjust gauge
wheels if you change the cutting height
of the mower deck.
TO STOP MOWER BLADES -
disengage attachment clutch control.
CAUTION: Do not operate the mower
without either the entire grass catcher,
on mowers so equipped, or the deflector
shield in place.

ADD GASOLINE
• Fill fuel tank to bottom of filler neck. Do
not overfill. Use fresh, clean, regular
unleaded gasoline with a minimum of
87 octane. (Use of leaded gasoline will
increase carbon and lead oxide deposits
and reduce valve life). Do not mix oil
with gasoline. Purchase fuel in quan-
tities that can be used within 30 days to
assure fuel freshness.
CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.
IMPORTANT: When operating in temper-
atures below32°F(0°C), use fresh, clean
winter grade gasoline to help insure good
cold weather starting.
CAUTION: Alcohol blended fuels (called
gasohol or using ethanol or methanol) can
attract moisture which leads to separa-
tion and formation of acids during storage.
TOWING CARTS AND OTHER ATTACH-
MENTS
Tow only the attachments that are recom-
mended by and comply with specifi cations
of the manufacturer of your tractor. Use
common sense when towing. Too heavy
of a load, while on a slope, is dangerous.
Tires can lose traction with the ground and
cause you to lose control of your tractor.
BEFORE STARTING THE ENGINE
CHECK ENGINE OIL LEVEL
The engine in your tractor has been
shipped, from the factory, already filled
with summer weight oil.
1. Check engine oil with tractor on level
ground.
2. Remove oil fill cap/dipstick and wipe
clean, reinsert the dipstick and screw
cap tight, wait for a few seconds, re-
move and read oil level. If necessary,
add oil until “FULL” mark on dipstick is
reached. Do not overfill.
• For cold weather operation you should
change oil for easier starting (See the
oil viscosity chart in the Maintenance
section of this manual).
• To change engine oil, see the Mainte-
nance section in this manual.
TO START ENGINE
When starting the engine for the first time
or if the engine has run out of fuel, it will
take extra cranking time to move fuel from
the tank to the engine.
1. Sit on seat in operating position,
depress clutch/brake pedal and set
parking brake.
2. Place gear shift lever in neutral (N)
position.
3. Move attachment clutch to disengaged
position.
4. Move throttle control to choke position.
NOTE: Before starting, read the warm
and cold starting procedures below.
5. Insert key into ignition and turn key
clockwise to start position and release
key as soon as engine starts. Do
not run starter continuously for more
than fifteen seconds per minute. If the
engine does not start after several
attempts, move throttle control to fast
position, wait a few minutes and try
again. If engine still does not start,
move the throttle control back to the
choke position and retry.
WARM WEATHER STARTING (50° F and
above)
6. When engine starts, move the throttle
control to the fast position.
• The attachments and ground drive can
now be used. If the engine does not
accept the load, restart the engine and
allow it to warm up for one minute using
the choke as described above.
COLD WEATHER STARTING ( 50° F and
below)
6. When engine starts, leave throttle
control in choke position until engine
warms up and begins to run roughly.
Once rough running begins, imme-
diately move the throttle control to the
fast position. Engine warm-up may
take from several seconds to several
minutes (the colder the temperature,
the longer the warm-up).
Acidic gas can damage the fuel system
of an engine while in storage. To avoid
engine problems, the fuel system should
be emptied before storage of 30 days
or longer. Drain the gas tank, start the
engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel
next season. See Storage Instructions for
additional information. Never use engine
or carburetor cleaner products in the fuel
tank or permanent damage may occur.

MOWING TIPS
• Mower should be properly leveled for
best mowing performance. See “TO
LEVEL MOWER HOUSING” in the
Service and Adjustments section of this
manual.
• The left hand side of mower should be
used for trimming.
• Drive so that clippings are discharged
onto the area that has already been
cut. Have the cut area to the right of
the tractor. This will result in a more
even distribution of clippings and more
uniform cutting.
• When mowing large areas, start by
turning to the right so that clippings will
discharge away from shrubs, fences,
driveways, etc. After one or two rounds,
mow in the opposite direction making
left hand turns until finished.
MULCHING MOWING TIPS
IMPORTANT: For best performance, keep
mower housing free of built-up grass and
trash. Clean after each use.
• The special mulching blade will recut
the grass clippings many times and
reduce them in size so that as they fall
onto the lawn they will disperse into
the grass and not be noticed. Also, the
mulched grass will biodegrade quickly
to provide nutrients for the lawn. Always
mulch with your highest engine (blade)
speed as this will provide the best recut-
ting action of the blades.
• Avoid cutting your lawn when it is wet.
Wet grass tends to form clumps and
interferes with the mulching action. The
best time to mow your lawn is the early
afternoon. At this time the grass has
dried, the newly cut area will not be
exposed to direct sunlight.
•For best results, adjust the mower
cutting height so that the mower cuts
off only the top one-third of the grass
blades. For extremely heavy grass, re-
duce your width of cut on each pass and
mow slowly.
• If grass is extremely tall, it should be
mowed twice to reduce load and pos-
sible fire hazard from dried clippings.
Make first cut relatively high; the second
to the desired height.
• Do not mow grass when it is wet.
Wet grass will plug mower and leave
undesirable clumps. Allow grass to dry
before mowing.
• Certain types of grass and grass
conditions may require that an area be
mulched a second time to completely
hide the clippings. When doing a sec-
ond cut, mow across (perpendicular) to
the first cut path.
• Change your cutting pattern from week
to week. Mow north to south one week
then change to east to west the next
week. This will help prevent matting and
graining of the lawn.
• Always operate engine at full throttle
when mowing to assure better mowing
performance and proper discharge of
material. Regulate ground speed by
selecting a low enough gear to give the
mower cutting performance as well as
the quality of cut desired.
• When operating attachments, select a
ground speed that will suit the terrain
and give best performance of the at-
tachment being used.
COLD WEATHER STARTING ( 50° F and
below)
6. When engine starts, leave throttle
control in choke position until engine
warms up and begins to run roughly.
Once rough running begins, imme-
diately move the throttle control to the
fast position. Engine warm-up may
take from several seconds to several
minutes (the colder the temperature,
the longer the warm-up).
• The attachments can also be used dur-
ing the engine warm-up period.
NOTE: If at a high altitude (above 3000
feet) or in cold temperatures (below 32 F)
the carburetor fuel mixture may need to
be adjusted for best engine performance
(see “TO ADJUST CARBURETOR” in the
Service and Adjustments section of this
manual).

pivot points which have special nylon
bearings. Viscous lubricants will attract
dust and dirt that will shorten the life of the
self-lubricating bearings. If you feel they
must be lubricated, use only a dry, pow-
dered graphite type lubricant sparingly.

GENERAL RECOMMENDATIONS
The warranty on this tractor does not
cover items that have been subjected to
operator abuse or negligence. To receive
full value from the warranty, operator
must maintain tractor as instructed in this
manual.
Some adjustments will need to be made
periodically to properly maintain your
tractor.
At least once a season, check to see if
you should make any of the adjustments
described in the Service and Adjustments
section of this manual.
• At least once a year you should replace
the spark plug, clean or replace air filter,
and check blades and belts for wear.
A new spark plug and clean air filter
assure proper air-fuel mixture and help
your engine run better and last longer.
BEFORE EACH USE
1. Check engine oil level.
2. Check brake operation.
3. Check tire pressure.
4. Check operator presence and
interlock systems for proper operation.
5. Check for loose fasteners.

18
TRACTOR
Always observe safety rules when per-
forming any maintenance.
BRAKE OPERATION
If tractor requires more than six (6) feet
stopping distance at high speed in highest
gear, then brake must be adjusted. (See
“TO ADJUST BRAKE” in the Service and
Adjustments section of this manual).
TIRES
• Maintain proper air pressure in all tires
(See “PRODUCT SPECIFICATIONS”
section of this manual).
• Keep tires free of gasoline, oil, or insect
control chemicals which can harm rub-
ber.
• Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may
cause tire damage.
NOTE: To seal tire punctures and prevent
flat tires due to slow leaks, tire sealant
may be purchased from your local parts
dealer. Tire sealant also prevents tire dry
rot and corrosion.
OPERATOR PRESENCE SYSTEM
Be sure operator presence and interlock
systems are working properly. If your trac-
tor does not function as described, repair
the problem immediately.
• The engine should not start unless the
clutch/brake pedal is fully depressed
and attachement clutch control is in the
disengaged position.
• When the engine is running, any at-
tempt by the operator to leave the seat
without first setting the parking brake
should shut off the engine.
• When the engine is running and the
attachment clutch is engaged, any at-
tempt by the operator to leave the seat
should shut off the engine.
• The attachment clutch should never op-
erate unless the operator is in the seat.
BLADE CARE
For best results mower blades must be
kept sharp. Replace bent or damaged
blades.
BLADE REMOVAL
1. Raise mower to highest position to al-
low access to blades.
2. Remove blade bolt, lock washer and
flat washer securing blade.
3. Install new or resharpened blade
with trailing edge up towards deck as
shown.
IMPORTANT: To ensure proper assembly,
center hole in blade must align with star
on mandrel assembly.
4. Reassemble blade bolt, lock washer
and flat washer in exact order as
shown.
5. Tighten blade bolt securely (27-35 Ft.
Lbs. torque).
IMPORTANT: Blade bolt is heat treated.
If bolt needs replacing, replace only with
approve bolt shown in the Repair Parts.
TO SHARPEN BLADE
NOTE: We do not recommend sharp-
ening blade - but if you do, be sure the
blade is balanced.
Care should be taken to keep the blade
balanced. An unbalanced blade will cause
excessive vibration and eventual damage
to mower and engine.
• The blade can be sharpened with a file
or on a grinding wheel. Do not attempt
to sharpen while on the mower.
• To check blade balance, you will need a
5/8" diameter steel bolt, pin, or a cone
balancer. (When using a cone balancer,
follow the instructions supplied with
balancer.)
NOTE: Do not use a nail for balancing
blade. The lobes of the center hole may
appear to be centered, but are not.
• Slide blade on to an unthreaded portion
of the steel bolt or pin and hold the
bolt or pin parallel with the ground. If
blade is balanced, it should remain in a
horizontal position. If either end of the
blade moves downward, sharpen the
heavy end until the blade is balanced.

NOTE: Although multi-viscosity oils
(5W30, 10W30 etc.) improve starting in
cold weather, they will result in increased
oil consumption when used above 32°F.
Check your engine oil level more frequent-
ly to avoid possible engine damage from
running low on oil.
Change the oil after every 50 hours of op-
eration or at least once a year if the tractor
is not used for 50 hours in one year.
Check the crankcase oil level before start-
ing the engine and after each eight (8)
hours of operation. Tighten oil fill cap/
dipstick securely each time you check the
oil level.
ENGINE
LUBRICATION
Only use high quality detergent oil rated
with API service classification SG-SL.
Select the oil’s SAE viscosity grade
according to your expected operating
temperature.
TO CHANGE ENGINE OIL

7. Refill engine with oil through oil fill dip-
stick tube. Pour slowly. Do not overfill.
For approximate capacity see “PROD-
UCT SPECIFICATIONS” section of this
manual.
8. Use gauge on oil fill cap/dipstick for
checking level. For accurate reading,
tighten dipstick cap securely onto the
tube before removing dipstick. Keep oil
at “FULL” line on dipstick. Tighten cap
onto the tube securely when finished.
NOTE: The original equipment battery on
your tractor is maintenance free. Do not
attempt to open or remove caps or covers.
Adding or checking level of electrolyte is
not necessary.
TO CLEAN BATTERY AND TERMINALS
Corrosion and dirt on the battery and
terminals can cause the battery to “leak”
power.
1. Remove terminal guard.
2. Disconnect BLACK battery cable first
then RED battery cable and remove
battery from tractor.
3. Rinse the battery with plain water and
dry.
4. Clean terminals and battery cable ends
with wire brush until bright.
5. Coat terminals with grease or petro-
leum jelly.
6. Reinstall battery (See “REPLACING
BATTERY" in the SERVICE AND AD-
JUSTMENTS section of this manual).
ENGINE OIL FILTER
Replace the engine oil filter every season
or every other oil change if the tractor is
used more than 100 hours in one year.
AIR FILTER
Your engine will not run properly using a
dirty air filter. Replace pre-cleaner after
every 25 hours of operation or every
season. Service paper cartridge every
100 hours of operation or every season,
whichever occurs first.
Service air cleaner more often under dusty
conditions.
