GENERAL SERVICE  
III. CHILDREN  
•
Never operate machine in a closed are.  
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 fuel-  
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.  
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.

•
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.  
•
•
•
•
•
•
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.  
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.  
•
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.  
Always look down and behind before and while back-  
ing.

V. SERVICE  
SAFE HANDLING OF GASOLINE  
•
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.  
To avoid personal injury or property damage, use extreme  
care in handling gasoline.Gasoline is extremely flammable  
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 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.  
•
•
•
If fuel is spilled on clothing, change clothing immedi-  
ately.  
Never overfill fuel tank. Replace gas cap and tighten  
securely.

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 op-  
erating your tractor or performing any adjustments or repairs. We recommend a wide  
vision safety mask over spectacles or standard safety glasses.  
NOTE: Under certain conditions when tractor is standing  
HOW TO USEYOUR TRACTOR  
idlewiththeenginerunning, hotengineexhaustgasesmay  
cause “browning” of grass. To eliminate this possibility, al-  
ways stop engine when stopping tractor on grass areas.  
TO SET PARKING BRAKE (See Fig. 7)  
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.  
CAUTION: Always stop tractor com-  
pletely,asdescribedabove,beforeleav-  
ing the operator's position; to empty  
grass catcher, etc.  
•
Depress clutch/brake pedal into full “BRAKE” position  
and hold.  
•
Place parking brake lever in“ENGAGED”position and  
releasepressurefromclutch/brakepedal. Pedalshould  
remain in “BRAKE” position. Make sure parking brake  
will hold tractor secure.  
TO USE THROTTLE CONTROL (See Fig. 7)  
Always operate engine at full throttle.

during hot months. For healthier and better looking  
lawns, mow often and after moderate growth.  
•
IMPORTANT:  
THE MOTION CONTROL LEVER DOES NOT  
RETURN TO NEUTRAL (N) POSITION WHEN THE CLUTCH/  
BRAKE PEDAL IS DEPRESSED.  
•
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.  
ENGINE -  
•
Move throttle control between half and full speed (fast)  
position.  
NOTE: Failure to move throttle control between half and  
fullspeed(fast)position,beforestoppingmaycauseengine  
to “backfire”.  
TO ADJUST GAUGE WHEELS (See Fig. 8)  
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.  
•
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.  
NOTE:Adjust gauge wheels with tractor on a flat level  
surface.  
IMPORTANT: LEAVING THE IGNITION SWITCH IN ANY  
POSITION OTHER THAN "STOP" WILL CAUSE THE BATTERY  
TO BE DISCHARGED, (DEAD).

OPERATION  
•
•
•
Place motion control lever in neutral (N) position.  
Move attachment clutch to “DISENGAGED” position.  
Move throttle control to choke position.  
TOWING CARTS AND OTHER ATTACHMENTS  
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.  
NOTE: Before starting, read the warm and cold starting  
procedures below.  
•
Insertkeyintoignitionandturnkeyclockwiseto“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.  
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.  
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.  
WARM WEATHER STARTING (50° F 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.  
•
•
•
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.  
COLD WEATHER STARTING ( 50° F 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 posi-  
tion.This may require 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 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.  
AUTOMATIC TRANSMISSION WARM UP  
•
Beforedrivingtheunitincoldweather,thetransmission  
should be warmed up as follows:  
•
•
Be sure the tractor is on level ground.  
Place the motion control lever in neutral.  
Release the parking brake and let the clutch/brake  
slowly return to operating position.  
CAUTION: Wipe off any spilled oil or  
fuel. Do not store, spill or use gasoline  
near an open flame.  
•
Allow one minute for transmission to warm up.This  
can be done during the engine warm up period.  
IMPORTANT: WHEN OPERATING IN TEMPERATURES  
BELOW32°F(0°C), USE FRESH, CLEAN WINTER GRADE  
GASOLINE TO HELP INSURE GOOD COLD WEATHER  
STARTING.  
•
The attachments can also be used during the engine  
warm-upperiodafterthetransmissionhasbeenwarmed  
up.  
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.  
CAUTION: Alcohol blended fuels (called gasohol or  
usingethanolormethanol)canattractmoisturewhich  
leads to separation and formation of acids during  
storage. Acidic gas can damage the fuel system of  
anenginewhileinstorage.Toavoidengineproblems,  
the fuel system should be emptied before storage  
of 30 days or longer. Drain the gas tank, start the  
engineandletitrununtilthefuellinesandcarburetor  
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.  
PURGE TRANSMISSION  
CAUTION: Never engage or disengage  
freewheel lever while the engine is run-  
ning.  
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  
BE PURGED AFTER REINSTALLATION BEFORE OPERATING  
THE TRACTOR.  
TO START ENGINE (See Fig. 6)  
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.

•
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.

MULCHING MOWING TIPS  
•
Engage transmission by placing freewheel control in  
driving position (See“TOTRANSPORT”in this section  
of manual).  
IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER  
HOUSING FREE OF BUILT-UP GRASS AND TRASH. CLEAN  
AFTER EACH USE.  
•
•
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.  
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 mo-  
tion control lever to the neutral (N) position. Repeat  
this procedure with the motion control lever three (3)  
times.  
•
The special mulching blade will recut the grass clip-  
pings 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 biode-  
grade quickly to provide nutrients for the lawn. Always  
mulch with your highest engine (blade) speed as this  
will provide the best recutting 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, yet 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  
grassblades(SeeFig.12).Forextremelyheavymulch-  
ing, reduce your width of cut on each pass and mow  
slowly.  
•
•
Your transmission is now purged and now ready for  
normal operation.  
•
MOWING TIPS  
•
Mower should be properly leveled for best mowing per-  
formance. See“TO LEVEL MOWER HOUSING”in the  
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.  
MAX 1/3  
•
Whenmowinglargeareas,startbyturningtotherightso  
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).  
FIG. 12  
•
Certaintypesofgrassandgrassconditionsmayrequire  
that an area be mulched a second time to completely  
hide the clippings. When doing a second cut, mow  
across (perpendicular) to the first cut path.  
•
Change your cutting pattern from week to week. Mow  
northtosouthoneweekthenchangetoeasttowestthe  
next week. This will help prevent matting and graining  
of the lawn.

Avoid stumps, stones, deep ruts, sharp objects and  
other hazards that may cause tire damage.  
FIG. 13  
TO SHARPEN BLADE (See Fig. 14)  
NOTE: We do not recommend sharpening blade - but if  
you do, be sure the blade is balanced.  
Care should be taken to keep the blade balanced. An un-  
balanced blade will cause excessive vibration and eventual  
damage to mower and engine.  
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.  
•
The blade can be sharpened with a file or on a grind-  
ing 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).

MAINTENANCE  
CLEAN AIR INTAKE/COOLING AREAS  
To insure proper cooling, make sure the grass screen,  
cooling fins, and other external surfaces of the engine are  
kept clean at all times.  
CLEANING  
•
•
•
Clean engine, battery, seat, finish, etc. of all foreign  
matter.  
Keep finished surfaces and wheels free of all gasoline,  
oil, etc.  
Protect painted surfaces with automotive type wax.  
Every 100 hours of operation (more often under extremely  
dusty, dirty conditions), remove the blower housing and  
other cooling shrouds. Clean the cooling fins and external  
surfaces as necessary. Make sure the cooling shrouds are  
reinstalled.  
We do not recommend using a garden hose or pressure  
washer to clean your tractor unless the engine and trans-  
mission are covered to keep water out. Water in engine or  
transmission will shorten the useful life of your tractor. Use  
compressed air or a leaf blower to remove grass, leaves  
and trash from tractor and mower.  
NOTE: Operating the engine with a blocked grass screen,  
dirtyorpluggedcoolingfins,and/orcoolingshroudsremoved  
will cause engine damage due to overheating. See engine  
manual.  
MUFFLER  
Inspect and replace corroded muffler and spark arrester  
(if equipped) as it could create a fire hazard and/or dam-  
age.  
SPARK PLUGS  
Replace spark plugs at the beginning of each mowing  
season or after every 100 hours of operation, whichever  
occurs first. Spark plug type and gap setting are shown in  
“PRODUCT SPECIFICATIONS” section of this manual.  
IN-LINE FUEL FILTER (See Fig. 17)  
The fuel filter should be replaced once each season. If fuel  
filter becomes clogged, obstructing fuel flow to carburetor,  
replacement is required.  
•
•
•
•
With engine cool, remove filter and plug fuel line sec-  
tions.

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.

BROWN  
BLACK  
EQUIPPED WITH A SPECIAL  
ALTERNATOR SYSTEM.  
THE LIGHTS ARE NOT  
CONNECTED TO THE  
BATTERY, BUT HAVE THEIR  
OWN ELECTRICAL SOURCE.  
BECAUSE OF THIS, THE  
HEADLIGHTS  
BRIGHTNESS OF THE LIGHTS  
WILL CHANGE WITH ENGINE  
SPEED. AT IDLE THE LIGHTS  
WILL DIM. AS THE ENGINE IS  
SPEEDED UP, THE LIGHTS  
WILL BECOME THEIR BRIGHTEST.
