SAFETY RULES
Safe Operation Practices for Ride-On Mowers
GENERAL SERVICE
III. CHILDREN
•
Never operate machine in a closed area.
Keep all nuts and bolts tight to be sure the equipment
is in safe working condition.
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.
•
•
•
Never tamper with safety devices. Check their proper
operation regularly.
•
•
•
•
Keepchildrenoutofthemowingareaandinthewatchful
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.
Nevercarrychildren,evenwiththebladesshutoff.They
may fall off and be seriously injured or interfere with
safemachineoperation.Childrenwhohavebeengiven
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.
Useextracarewhenapproachingblindcorners,shrubs,
trees, or other objects that may block your view of a
child.
Keep machine free of grass, leaves, or other debris
build-up. Cleanoilorfuelspillageandremoveanyfuel-
soaked debris. Allow machine to cool before storing.
If you strike a foreign object, stop and inspect the
machine. Repair, if necessary, before restarting.
Nevermakeanyadjustmentsorrepairswiththeengine
running.
Check grass catcher components and the discharge
guard frequently and replace with manufacturer's rec-
ommended parts, when necessary.
Mower blades are sharp. Wrap the blade or wear
gloves, and use extra caution when servicing them.
Check brake operation frequently. Adjust and service
as required.
Maintain or replace safety and instruction labels, as
necessary.

IV. TOWING
•
Tow only with a machine that has a hitch designed for
towing. Do not attach towed equipment except at the
hitch point.
•
•
•
•
Follow the manufacturer's recommendation for weight
limits for towed equipment and towing on slopes.
Never allow children or others in or on towed equip-
ment.
•
Be sure the area is clear of bystanders before operat-
ing. Stop machine if anyone enters the area.
Never carry passengers.
Do not mow in reverse unless absolutely necessary.
Alwayslookdownandbehindbeforeandwhilebacking.
Nevercarrychildren,evenwiththebladesshutoff.They
may fall off and be seriously injured or interfere with
safemachineoperation.Childrenwhohavebeengiven
rides in the past may suddenly appear in the mowing
area for another ride and be run over or backed over
by the machine.
Keepchildrenoutofthemowingareaandinthewatchful
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.
Mow up and down slopes (15° Max), not across.
Choose a low ground speed so that you will not have
to stop or shift while on the slope.
Avoid starting, stopping, or turning on a slope. If the
tires lose traction, disengage the blades and proceed
slowly straight down the slope.
If machine stops while going uphill, disengage blades,
shift into reverse and back down slowly.
Do not turn on slopes unless necessary, and then, turn
slowly and gradually downhill, if possible.
On slopes, the weight of the towed equipment may
cause loss of traction and loss of control.
Travel slowly and allow extra distance to stop.

•
Use only approved gasoline container.
Never remove gas cap or add fuel with the engine
running. Allow engine to cool before refueling.
Never fuel the machine indoors.
•
•
Never store the machine or fuel container where there
is an open flame, spark, or pilot light such as on a water
heater or other appliances.
•
•
•
•
Never fill containers inside a vehicle or on a truck or
trailer bed with plastic liner. Always place containers
on the ground away from your vehicle when filling.
Remove gas-powered equipment from the truck or
trailer and refuel it on the ground. If this is not possible,
then refuel such equipment with a portable container,
rather than from a gasoline dispenser nozzle.

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.
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.
•
•
Check engine oil with tractor on level ground.
WARM WEATHER STARTING (50° F and above)
Removeoilfillcap/dipstickandwipeclean, reinsertthe
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).
•
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.

then move throttle control to fast position. This may re-
quire an engine warm-up period from several seconds
to several minutes, depending on the temperature.
ADD GASOLINE
•
Fill fuel tank to bottom of filler neck. Do not overfill. Use
fresh, clean, regular unleaded gasoline with a minimum
of87octane.(Useofleadedgasolinewillincreasecarbon
andleadoxidedepositsandreducevalvelife). Donotmix
oil with gasoline. Purchase fuel in quantities that can be
used within 30 days to assure fuel freshness.

MOWING TIPS
PURGE TRANSMISSION
•
Mower should be properly leveled for best mowing
performance. See “TO LEVEL MOWER HOUSING” in
the Service and Adjustments section of this manual.
CAUTION: Never engage or disengage
freewheel lever while the engine is
running.
•
•
The left hand side of mower should be used for trim-
ming.
Drive so that clippings are discharged onto the area
that has been cut. Have the cut area to the right of the
machine. This will result in a more even distribution of
clippings and more uniform cutting.
To ensure proper operation and performance, it is recom-
mended 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 devel-
oped during shipping of your tractor.
IMPORTANT: SHOULD YOUR TRANSMISSION REQUIRE
REMOVAL FOR SERVICE OR REPLACEMENT, IT SHOULD
BEPURGEDAFTERREINSTALLATIONBEFOREOPERATING
THE TRACTOR.
•
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).
•
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 en-
gine is running, move throttle control to slow position.
Disengage parking brake
CAUTION: At any time, there may be
movement of the drive wheels.
Fig. 13
•
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 mow-
ing to assure better mowing performance and proper
discharge of material. Regulate ground speed by se-
lecting 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.
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 sec-
tion 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.

•
•
•
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.
•
Clean entire tractor (See “CLEANING” in the Mainte-
nance section of this manual).
Inspect and replace belts, if necessary (See belt re-
placement instructions in the Service and Adjustments
section of this manual).
Use fresh fuel next season.
NOTE: Fuel stabilizer is an acceptable alternative in mini-
mizing 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.
•
•
•
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.
•
•
Remove spark plug(s).
Pour one ounce of oil through spark plug hole(s) into
cylinder(s).
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 dis-
connected and battery cleaned thoroughly (See “TO
CLEAN BATTERY AND TERMINALS” in the Mainte-
nance section of this manual).
•
•
•
Turn ignition key to “START” position for a few seconds
to distribute oil.
Replace with new spark plug(s).
•
•
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.
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.
