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.  
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.  
Do not mow in reverse unless absolutely necessary.  
Always look down and behind before and while back-  
ing.  
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.  
V. SERVICE  
SAFE HANDLING OF GASOLINE  
To avoid personal injury or property damage, use extreme  
careinhandlinggasoline. Gasolineisextremelyflammable  
and the vapors are explosive.  
Extinguish all cigarettes, cigars, pipes, and other  
sources of ignition.  
Use only approved gasoline container.  
Never remove gas cap or add fuel with the engine run-  
ning. 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.  
Removegas-poweredequipmentfromthetruckortrailer  
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.  
Keep the nozzle in contact with the rim of the fuel tank  
orcontaineropeningatalltimesuntilfuelingiscomplete.  
Do not use a nozzle lock-open device.  
If fuel is spilled on clothing, change clothing immedi-  
ately.  
Never overfill fuel tank. Replace gas cap and tighten  
securely.  
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.

OPERATION  
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.  
HOW TO USE YOUR TRACTOR  
CAUTION: Always stop tractor com-  
pletely,asdescribedabove,beforeleav-  
ing the operator's position; to empty  
grass catcher, etc.  
TO SET PARKING BRAKE (See Fig. 6)  
Your tractor is equipped with an operator presence sens-  
ing 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.  
TOUSETHROTTLECONTROL(D)(SeeFig. 7)  
Always operate engine at full speed (fast).  
Depress clutch/brake pedal into full “BRAKE” position  
and hold.  
Operating engine at less than full speed (fast) reduces  
the engine's operating efficiency.  
Full speed (fast) offers the best mower performance.

OPERATION  
TO ADJUST MOWER CUTTING HEIGHT  
TO OPERATE MOWER (See Fig. 10)  
(See Fig. 9)  
Your tractor isequipped withan operator presencesensing  
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 hesitat-  
ing or cutting off when operating your equipment on rough,  
rolling terrain or hills.  
The position of the attachment lift lever (A) determines the  
cutting height.  
Select desired height of cut with attachment lift lever.  
Start mower blades by engaging attachment clutch  
control.  
A
TO STOP MOWER BLADES -  
disengage attachment clutch control.  
Fig. 9  
CAUTION: Do not operate the mower  
Put attachment lift lever in desired cutting height slot.  
without either the entire grass catcher,  
on mowers so equipped, or the deflec-  
tor shield (S) in place.  
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.  
Theaveragelawnshouldbecuttoapproximately2-1/2  
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.  
S
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.  
REVERSE OPERATION SYSTEM (ROS)  
Your tractor is equipped with a Reverse Operation System  
(ROS). Any attempt by the operator to travel in the reverse  
directionwiththeattachmentclutchengagedwillshutoffthe  
engineunlessignitionkeyisplacedintheROS"ON"position.  
Fig. 10  
WARNING: Backing up with the attachment clutch en-  
gaged while mowing is strongly discouraged. Turning the  
ROS "ON", to allow reverse operation with the attachment  
clutch engaged, should only be done when the operator  
decides it is necessary to reposition the machine with the  
attachment engaged. Do not mow in reverse unless  
absolutely necessary.  
TO OPERATE ON HILLS  
CAUTION: Do not drive up or down  
hills with slopes greater than 15° and  
do not drive across any slope.  
USING THE REVERSE OPERATION SYSTEM -  
Only use if you are certain no children or other bystanders  
will enter the mowing area.  
Choose the slowest speed before starting 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 position and engage parking  
brake.

OPERATION  
ADD GASOLINE  
TO TRANSPORT  
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.  
When pushing or towing your tractor, be sure to disengage  
transmission by placing freewheel control in freewheeling  
position. Free wheel control is located at the rear drawbar  
of tractor.  
Raiseattachmentlifttohighestpositionwithattachment  
lift control.  
Pull freewheel control out and into the slot and release  
so it is held in the disengaged position.  
CAUTION: Wipe off any spilled oil or  
fuel. Do not store, spill or use gasoline  
near an open flame.  
Do not push or tow tractor at more than two (2) MPH.  
To reengage transmission, reverse above procedure.  
IMPORTANT: WHEN OPERATING IN TEMPERATURES  
BELOW32°F(0°C), USE FRESH, CLEAN WINTER GRADE  
GASOLINE TO HELP INSURE GOOD COLD WEATHER  
STARTING.  
TRANSMISSION ENGAGED  
CAUTION: Alcohol blended fuels (called gasohol  
or using ethanol or methanol) can attract moisture  
which leads to separation and formation of acids  
duringstorage. Acidicgascandamagethefuelsys-  
tem of an engine while in storage. To avoid engine  
problems,thefuelsystemshouldbeemptiedbefore  
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.  
SeeStorageInstructionsforadditionalinformation.  
Never use engine or carburetor cleaner products in  
the fuel tank or permanent damage may occur.  
TRANSMISSION DISENGAGED  
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 START ENGINE (See Fig. 5)  
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.  
TOWINGCARTSANDOTHERATTACHMENTS  
Besurefreewheelcontrolisinthetransmissionengaged  
position.  
Tow only the attachments that are recommended by and  
comply with specifications of the manufacturer of your trac-  
tor. 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.  
Sit on seat in operating position, depress clutch/brake  
pedal and set parking brake.  
Place motion control lever in neutral (N) position.  
Move attachment clutch to “DISENGAGED” position.  
Move throttle control to fast position  
Pull choke control out for a cold engine start attempt.  
For a warm engine start attempt the choke control may  
not be needed.  
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.  
NOTE: Before starting, read the warm and cold starting  
procedures below.  
Check engine oil with tractor on level ground.  
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.  
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  
“FULLmark 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).  
WARM WEATHER STARTING (50° F and above)  
To change engine oil, see the Maintenance section in  
this manual.  
When engine starts, slowly push choke control in until  
theenginebeginstorunsmoothly.Iftheenginestartsto  
run roughly, pull the choke control out slightly for a few  
secondsandthencontinuetopushthecontrolinslowly.  
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.

tion of manual).  
7. Sitting in the tractor seat, start engine. After the engine  
is running, move throttle control to half (1/2) speed.  
With motion control lever in neutral (N) position, slowly  
disengage clutch/brake pedal.  
8. Slowly move motion control lever forward, after the  
tractor moves approximately five (5) feet, slowly move  
motion control lever to reverse position. After the trac-  
tor moves approximately five (5) feet return the motion  
control lever to the neutral (N) position. Repeat this  
procedure with the motion control lever three (3) times.  
AUTOMATIC TRANSMISSION WARM UP  
Beforedrivingtheunitincoldweather,thetransmission  
should be warmed up as follows:  
Be sure the tractor is on level ground.  
Your transmission is now purged and now ready for normal  
operation.  
Place the motion control lever in neutral.  
Release the parking brake and let the clutch/brake  
slowly return to operating position.  
Allowoneminutefortransmissiontowarmup.This  
can be done during the engine warm up period.  
MOWING TIPS  
Mowershouldbeproperlyleveledforbestmowingper-  
formance. See"TOLEVELMOWERHOUSING"inthe  
Service and Adjustments section of this manual.  
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.  
The attachments can be used during the engine warm-  
up period after the transmission has been warmed up  
andmayrequirethechokecontrolbepulledoutslightly.  
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.  
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. 11).  
PURGE TRANSMISSION  
CAUTION: Never engage or disengage  
freewheelleverwhiletheengineisrunning.  
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 de-  
veloped during shipping of your tractor.  
IMPORTANT: SHOULD YOUR TRANSMISSION REQUIRE  
REMOVAL FOR SERVICE OR REPLACEMENT, IT SHOULD  
BEPURGEDAFTERREINSTALLATIONBEFOREOPERATING  
THE TRACTOR.  
1. Place tractor safely on a level surface - that is clear  
and open - with engine off and parking brake set.  
2. Disengage transmission by placing freewheel control  
in freewheeling 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. With  
motion control lever in neutral (N) position, slowly  
disengage clutch/brake pedal.  
Fig. 11  
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.  
CAUTION: At any time, during step 4,  
there may be movement of the drive  
wheels.  
4. Move motion control lever to full forward position and  
hold for five (5) seconds. Move lever to full reverse  
position and hold for five (5) seconds. Repeat this  
procedure three (3) times.  
5. Move motion control lever to neutral (N) position. Shut-  
off engine and set parking brake.

where fumes may reach an open flame  
orspark. Allowtheenginetocoolbefore  
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.  
Removemowerfromtractorforwinterstorage. Whenmower

all dirt, grease, leaves, etc. Store in a clean, dry area.  
Clean entire tractor (See “CLEANING” in the Mainte-  
nance 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.  
Inspect and replace belts, if necessary (See belt re-  
placement 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.  
ENGINE OIL  
Touch up all rusted or chipped paint surfaces; sand  
Drain oil (with engine warm) and replace with clean en-  
gine oil. (See “ENGINE” in the Maintenance section of  
this manual).  
lightly before painting.  
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 dis-  
connected and battery cleaned thoroughly (see “TO  
CLEAN BATTERY AND TERMINALS” in the Mainte-  
nance section of this manual).  
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).  
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.
