plug.
CAUTION: Do not coast down a hill
in neutral, you may lose control of the
tractor.
CAUTION: Tow only the attachments
that are recommended by and comply
with specifications 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
components contain or emit chemicals
known to the State of California to cause
cancer and birth defects or other repro-
ductive harm.
,_WARNING: Battery posts, terminals
and related accessories contain lead
and lead compounds, chemicals known

I. GENERAL OPERATION
• Read, understand, and follow all
instructions 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 absolutely
necessary. Always look down and
behind before and while backing.
• Be aware of the mower discharge
direction 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
unattended. Always turn off blades, set
parking brake, stop engine, and remove
keys before dismounting.
•Tum 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 unload-
ing 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
injuries. These operators should
evaluate their ability to operate the riding
mower safely enough to protect them-
selves 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 re-
suit 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.
3
DO:
• Mow up and down slopes, not across.
• Remove obstacles such as rocks, tree
limbs, etc.
• Watch for holes, ruts, or bumps. Uneven
terrain could overturn the machine. Ta//
grass can hide obstacles.
• Use slow speed. Choose a low gear so
that you will not have to stop or shift
whi_e on the slope.
• Follow the manufacturer's recommenda-
tions 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 necessary,
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
machine and the mowing activity. Never
assume 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
equipment 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
arrow objects to be thrown. Frequently
check components and replace with
manufacturer's recommended pads,
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.
Adjust and service as required.

STOPPING
MOWER BLADES -
• To stop mower blades, push attachment
clutch switch in to disengaged position.
GROUND DRIVE -
• To stop ground drive, depress brake
pedal all the way down.
IMPORTANT: Forward and reverse drive
pedals return to neutral position when not
depressed.
ENGINE -
• Move throttle control to slow position.
NOTE: Failure to move throttle control to
slow position and allowing 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
completely, as described above, before
leaving the operator's position.
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.
TO USE CHOKE CONTROL
Use choke control whenever you are
starting a cold engine. Do not use to start
a warm engine.
• To engage choke control, pull knob out.
Slowly push knob in to disengage.
TO MOVE FORWARD AND BACKWARD
The direction and speed of movement is
controlled by the forward and reverse drive
pedals.
1. Start tractor and release parking brake.
2. Slowly depress forward or reverse
drive pedal to begin movement.
Ground speed increases the further
down the pedal is depressed.
TO USE CRUISE CONTROL
The cruise control feature can be used for
forward travel only.
1. With forward drive pedal depressed to
desired speed, move cruise control
lever forward to "SET" position and
hold while lifting your foot off the
pedal, then release the cruise control
lever.
To disengage the cruise control, pull the
lever backward to "OFF" position, or fully
depress the brake pedal.
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
measured from the ground to the blade tip
with the engine not running.
11
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
approximately 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.
• 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 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
desired cutting height.
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.

TOWING CARTSAND OTHERATTACH-
MENTS
Towonly the attachmentsthat are
recommendedby and comply with
specificationsof the manufacturer of your
tractor.Usecommon sensewhen towing.
Tooheavy of a load,while on a slope, is
dangerous.Tirescan lose traction with
the groundand cause you to lose control
ofyour tractor.
BEFORE STARTING THE ENGINE
CHECKENGINEOIL 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. Unthread and remove oil fill cap/
dipstick; wipe oil off. Reinsert the
dipstick into the tube and rest oil fill
cap on the tube. Do not thread the
cap onto the tube. Remove 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.
ADD GASOLINE
• Fill fuel tank to bottom of tank 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. Pumhase
fuel in quantities 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 tem-
peratures below 32°F(0°C), use fresh,
clean winter grade gasoline to help
insure good cold weather starting.
_I4,CAUTION: Alcohol blended fuels
(called gasohol or using ethanol or
methanol) can attract moisture which
leads to separation and formation of
acids during storage. 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 Instruc-
tions for additional information.
Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.
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. Be sure freewheel control is in the
transmission engaged position.
2. Sit on seat in operating position,
depress brake pedal and set parking
brake.
3. Move attachment clutch to disen-
gaged position.
4. Move throttle control to fast position
5. Pull choke control out for a cold
engine start attempt. For a warm
engine start attempt the choke control
may not be needed.
NOTE: Before starting, read the warm and
cold starting procedures below.
6. 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, push choke control in, wait a
few minutes and try again. If engine
still does not start, pull the choke
control out and retry.
WARM WEATHER STARTING (50 ° F and
above)
7. When engine starts, slowly push
choke control in until the engine
begins to run smoothly. If the engine
starts to run roughly, pull the choke
control out slightly for a few seconds
and then continue to push the control
in slowly.
• 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)
7. When engine starts, slowly push
choke control in until the engine
begins to run smoothly. Continue to
push the choke control in small steps
allowing the engine to accept small
changes in speed and load, until the
choke control is fully in.
If the engine starts to run roughly, pull
the choke control out slightly for a few
seconds and then continue to push
the control in slowly. This may require
an engine warm-up period from
several seconds to several minutes,
depending on the temperature.

AUTOMATIC TRANSMISSION WARM UP
Before driving the unit in cold weather,
the transmission should be warmed up as
follows:
1. Be sure the tractor is on level ground.
2. Release the parking brake and let the
brake slowly return to operating
position.
3. Allow one minute for transmission to
warm up. This can be done during the
engine warm up period.
• The attachments can be used during
the engine warm-up period after the
transmission has been warmed up and
may require the choke control be
pulled out slightly.
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).
PURGE TRANSMISSION
_CAUTION: Never engage or disengage
freewheel lever while the engine is running.
To ensure proper operation and perfor-
mance, it is recommended that the transmis-
sion be purged before operating tractor for
the first time. This procedure will remove any
trapped air inside the transmission which
may have developed during shipping of
your tractor.
IMPORTANT: Should your transmission
require removal for service or replacement,
it should be purged after reinstallation
before operating the tractor.
1. Place tractor safely on level surface
with engine off and parking brake set.
2. Disengage transmission by placing
freewheel control in disengaged
position (See "TO TRANSPORT" in this
section of manual).
3. Sitting in the tractor seat, start engine.
After the engine is running, move
throttle control to slow position.
Disengage parking brake.
4. Depress forward drive pedal to full
forward position and hold for five (5)
seconds and release pedal. Depress
reverse drive pedal to full reverse
position and hold for five (5) seconds
and release pedal. Repeat this
procedure three (3) times.
NOTE: During this step there will be no
movement of drive wheels. The air is being
removed from hydraulic drive system.
5. Shut off engine and set parking brake.
6. Engage transmission by placing
freewheel control in "transmission
engaged" position (See "TO TRANS-
PORT" in this section of manual).
7. Sitting in the tractor seat, start engine.
After the engine is running, move
throttle control to half (1/2)speed.
Disengage parking brake.
8. Drive tractor forward for approximately
five feet then backwards for five feet.
Repeat this driving procedure three
times.
Your transmission is now purged and
ready for normal operation.
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.
J
• If grass is extremely tall, it should be
mowed twice to reduce load and
possible fire hazard from dried clip-
pings. 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.
• 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 operatingattachments, select a
ground speed that will suit the terrain
and give best performance of the
attachment being u_ed

BRAKE OPERATION
If tractor requires more than six (6) feet
stopping distance at high speed in
highest gear, then brake must be ad-
justed. (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
rubber.
• 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 that operator presence and
interlock systems are working properly. If
your tractor does not function as de-
scribed below, repair the problem
immediately.
• The engine should not start unless the
brake pedal is fully depressed and
attachment clutch control is in the
disengaged position.
• When the engine is running, any
attempt 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
attempt by the operator to leave the
seat should shut off the engine.
• The attachment clutch should never
operate unless the operator is in the
seat.
BLADE CARE

TO SHARPEN BLADE
NOTE; We do not recommend sharpen-
ing 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 bal-
ancer, follow the instructions supplied
with batancer,)
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.
