WARNING

II. SLOPE OPERATION

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.

Slopes are a major factor related to loss of control and
tip-over accidents, which can result in severe injury or
death. Operation on all slopes requires extra caution. If
you cannot back up the slope or if you feel uneasy on it,
do not mow it.
• Mow up and down slopes, not across.
• Watch for holes, ruts, bumps, rocks, or other hidden
objects. Uneven terrain could overturn the machine.
Tall grass can hide obstacles.
• Choose a low ground speed so that you will not have
to stop or shift while on the slope.
• Do not mow on wet grass. Tires may lose traction.
Always keep the machine in gear when going down
slopes. Do not shift to neutral and coast downhill.
• Avoid starting, stopping, or turning on a slope. If the
tires lose traction, disengage the blades and proceed
slowly straight down the slope.
• Keep all movement on the slopes slow and gradual.
Do not make sudden changes in speed or direction,
which could cause the machine to roll over.
• Use extra care while operating machine with grass
catchers or other attachments; they can affect the
stability of the machine. Do no use on steep slopes.
• Do not try to stabilize the machine by putting your foot
on the ground.
• Do not mow near drop-offs, ditches, or embankments.
The machine could suddenly roll over if a wheel is over
the edge or if the edge caves in.

I. GENERAL OPERATION

SAFETY RULES
Safe Operation Practices for Ride-On Mowers
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 in the watchful
care of a responsible adult other than the operator.
• Be alert and turn machine off if a child enters the
area.
• Before and while backing, look behind and down for
small children.
• Never carry children, even with the blades shut off. They
may fall off and be seriously injured or interfere with
safe machine operation. Children who have been given
rides in the past may suddenly appear in the mowing
area for another ride and be run over or backed over
by the machine.
• Never allow children to operate the machine.
• Use extra care when approaching blind corners, shrubs,
trees, or other objects that may block your view of a
child.

GENERAL SERVICE
• Never operate machine in a closed area.
• Keep all nuts and bolts tight to be sure the equipment
is in safe working 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 and remove any fuelsoaked debris. Allow machine to cool before storing.
• If you strike a foreign object, stop and inspect the
machine. Repair, if necessary, before restarting.
• Never make any adjustments or repairs with the engine
running.

OPERATION
TO MOVE FORWARD AND BACKWARD
(See Fig. 7)

•

The direction and speed of movement is controlled by the
forward and reverse drive pedals.
• Start tractor and release parking brake.
• Slowly depress forward (K) or reverse (L) drive pedal to
begin movement. Ground speed increases the further
down the pedal is depressed.

•

The average lawn should be cut to approximately
2-1/2" during the cool season and to over 3" during hot
months. For healthier and better looking lawns, mow
often and after moderate growth.
For best cutting performance, grass over 6" in height
should be mowed twice. Make the first cut relatively
high; the second to desired height.

TO ADJUST GAUGE WHEELS (See Fig. 9)
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: Adjust gauge wheels with tractor on a flat level
surface.
• Adjust mower to desired cutting height (See “TO ADJUST
MOWER CUTTING HEIGHT” in this section of manual).
• With mower in desired height of cut position, gauge wheels
should be assembled so they are slightly off the ground.
Install gauge wheel in appropriate hole. Tighten securely.
• Repeat for all, installing gauge wheel in same adjustment hole.

TO USE CRUISE CONTROL (J) (See Fig. 7)
The cruise control feature can be used for forward travel only.

J
L

Fig. 7
SYSTEM CHARACTERISTICS
The cruise control should only be used while mowing or
transporting on relatively smooth, straight surfaces. Other
conditions such as trimming at slow speeds may cause the
cruise control to disengage. Do not use the cruise control
on slopes, rough terrian or while trimmimg or turning.
• With forward drive pedal depressed to desired speed,
pull cruise control lever (J) up and hold while lifting
your foot off the pedal, then release the lever.

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 equipment on rough,
rolling terrain or hills.
1. Select desired height of cut with attachment lift lever.
2. Start mower blades by engaging attachment clutch.

The position of the attachment lift lever (A) determines the
cutting height.

TO STOP MOWER BLADES Disengage attachment clutch control.

Fig. 8
• Put attachment lift lever in desired cutting height slot.
The cutting height range is approximately 1" to 4". The
heights are measured 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.

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.

CHECK ENGINE OIL LEVEL
The engine in your tractor has been shipped, from the
factory, already filled with summer weight oil.
• Check engine oil with tractor on level ground.
• Remove oil fill cap/dipstick and wipe clean, reinsert the
dipstick and screw cap tight, wait for a few seconds,
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 “OIL VISCOSITY CHART” in the
Maintenance section of this manual).
• To change engine oil, see the Maintenance section in
this manual.

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 quantities that can be
used within 30 days to assure fuel freshness.

WARM WEATHER STARTING (50° F/10° C and above)
• 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.

CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.

COLD WEATHER STARTING (50° F/10° C and below)
• When engine starts, allow engine to run with the throttle
control in the choke position until the engine runs roughly, then move throttle control to fast position. This may
require an engine warm-up period from several seconds
to several minutes, depending on the temperature.

IMPORTANT: WHEN OPERATING IN TEMPERATURES BELOW
32°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 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
Instructions for additional information. Never use
engine or carburetor cleaner products in the fuel
tank or permanent damage may occur.

AUTOMATIC TRANSMISSION WARM UP
• Before driving the unit in cold weather, the transmission
should be warmed up as follows:
• Be sure the tractor is on level ground.
• Release the parking brake and let the brake slowly
return to operating position.
• Allow one minute for transmission to warm up. This
can be done during the engine warm up period.
• The attachments can also be used during the engine warmup period after the transmission has been warmed up.
NOTE: If at a high altitude (above 3000 feet) or in cold temperatures (below 32° F/10° C) 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.

OPERATION
PURGE TRANSMISSION

MOWING TIPS
•

CAUTION: Never engage or disengage
freewheel lever while the engine is
running.

•

To ensure proper operation and performance, it is recommended that the transmission 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.

•

•
•
•

Place tractor safely on a level surface - that is clear
and open - with engine off and parking brake set.
Disengage transmission by placing freewheel control
in freewheeling position (See “TO TRANSPORT” in
this section of manual).
Sitting in the tractor seat, start engine. After the engine is running, move throttle control to slow position.
Disengage parking brake

Tire chains cannot be used when the mower housing
is attached to tractor.
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 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 (See Fig. 13).

CAUTION: At any time, there may be
movement of the drive wheels.
•

Depress forward drive pedal to full forward position,
hold for five (5) seconds and release pedal. Depress
reverse drive pedal to full reverse position, hold for five
(5) seconds and release pedal. Repeat this procedure
three (3) times.
• Shut off engine and set parking brake.
• Engage transmission by placing freewheel control in
engaged position (See “TO TRANSPORT” in this section of manual).
• Sitting in the tractor seat, start engine. After the engine
is running, move throttle control to half (1/2) speed.
Disengage parking brake.
• Drive tractor forward for approximately five feet then
backwards for five feet. Repeat this driving procedure
three times.
Your transmission is now purged and now ready for normal
operation.

Fig. 13
•

•
•

•

If grass is extremely tall, it should be mowed twice to
reduce load and possible 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.
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 attachment being used.

STORAGE
Immediately prepare your tractor for storage at the end
of the season or if the tractor will not be used for 30 days
or more.

ENGINE
FUEL SYSTEM
IMPORTANT: IT IS IMPORTANT TO PREVENT GUM DEPOSITS
FROM FORMING IN ESSENTIAL FUEL SYSTEM PARTS SUCH
AS CARBURETOR, FUEL FILTER, FUEL HOSE, OR TANK
DURING STORAGE. ALSO, EXPERIENCE INDICATES THAT
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.

WARNING: Never store the tractor with
gasoline in the tank inside a building
where fumes may reach an open flame
or spark. Allow the engine to cool before
storing in any enclosure.

TRACTOR

•

Empty the fuel tank by starting the engine and let it run
until the fuel lines and carburetor are empty.
• Never use engine or carburetor cleaner products in
the fuel tank or permanent damage may occur.
• Use fresh fuel next season.
NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage.
Add stabilizer to gasoline in fuel tank or storage container.
Always follow the mix ratio found on stabilizer container.
Run engine at least 10 minutes after adding stabilizer to
allow the stabilizer to reach the carburetor. Do not empty
the gas tank and carburetor if using fuel stabilizer.

Remove mower from tractor for winter storage. When mower
is to be stored for a period of time, clean it thoroughly, remove
all dirt, grease, leaves, etc. Store in a clean, dry area.
• Clean entire tractor (See “CLEANING” in the Maintenance section of this manual).
• Inspect and replace belts, if necessary (See belt replacement instructions in the Service and Adjustments
section of this manual).
• Lubricate as shown in the Maintenance section of this
manual.
• Be sure that all nuts, bolts and screws are securely
fastened. Inspect moving parts for damage, breakage
and wear. Replace if necessary.
• Touch up all rusted or chipped paint surfaces; sand
lightly before painting.

ENGINE OIL
Drain oil (with engine warm) and replace with clean engine
oil. (See “ENGINE” in the Maintenance section of this
manual).

BATTERY
•
•

•

•
•

CYLINDER(S)

Fully charge the battery for storage.
After a period of time in storage, battery may require
recharging.
To help prevent corrosion and power leakage during
long periods of storage, battery cables should be disconnected and battery cleaned thoroughly (see “TO
CLEAN BATTERY AND TERMINALS” in the Maintenance section of this manual).
After cleaning, leave cables disconnected and place
cables where they cannot come in contact with battery
terminals.
If battery is removed from tractor for storage, do not
store battery directly on concrete or damp surfaces.

•
•
•
•

Remove spark plug(s).
Pour one ounce of oil through spark plug hole(s) into
cylinder(s).
Turn ignition key to “START” position for a few seconds
to distribute oil.
Replace with new spark plug(s).

OTHER
•
•
•
•

Do not store gasoline from one season to another.
Replace your gasoline can if your can starts to rust.
Rust and/or dirt in your gasoline will cause problems.
If possible, store your tractor indoors and cover it to
give protection from dust and dirt.
Cover your tractor with a suitable protective cover that
does not retain moisture. Do not use plastic. Plastic
cannot breathe which allows condensation to form and
will cause your tractor to rust.

IMPORTANT: NEVER COVER TRACTOR WHILE ENGINE
AND EXHAUST AREAS ARE STILL WARM.
