•
Besuretheareaisclearofotherpeoplebeforemowing.  
Look for this symbol to point out im-  
portant safety precautions. It means  
CAUTION!!! BECOMEALERT!!! YOUR  
SAFETY IS INVOLVED.  
Stop machine if anyone enters the area.  
Nevercarrypassengersorchildrenevenwiththeblades  
off.  
Do not mow in reverse unless absolutely necessary.  
Alwayslookdownandbehindbeforeandwhilebacking.  
Never carry children. They may fall off and be seriously  
injured or interfere with safe machine operation.  
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.  
Mow up and down slopes (15° Max), not across.  
Remove obstacles such as rocks, tree limbs, etc.  
Watch for holes, ruts, or bumps. Uneven terrain could  
overturn the machine. Tall grass can hide obstacles.  
CAUTION: Inordertopreventacciden-  
talstartingwhensettingup,transport-  
ing, adjusting or making repairs, al-  
ways disconnect spark plug wire and  
placewirewhereitcannotcontactspark  
plug.  
•
•
CAUTION: Do not coast down a hill in  
neutral, you may lose control of the  
tractor.  
•
•
•
•
•
Use slow speed. Choose a low gear so that you will not  
have to stop or shift while on the slope.  
Avoid starting or stopping on a slope. If 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.  
CAUTION: Tow only the attachments  
that are recommended by and comply  
withspecificationsofthemanufacturer  
of your tractor. Use common sense  
when towing. Operate only at the low-  
est 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.

ADD GASOLINE  
•
Fill fuel tank. 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 and above)

•
•
Be sure the tractor is on level ground.  
Release the parking brake and let the brake slowly  
return to operating position.

MULCHING MOWING TIPS  
IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER  
HOUSING FREE OF BUILT-UP GRASS AND TRASH.  
CLEAN AFTER EACH USE.  
•
Thespecialmulchingbladewillrecutthegrassclippings  
many times and reduce them in size so that as they fall  
ontothelawntheywilldisperseintothegrassandnotbe  
noticed. Also, the mulched grass will biodegrade  
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.  
Avoidcutting yourlawn whenitis wet. Wet grasstends  
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 and the newly cut area  
will not be exposed to the direct sun.  
Forbestresults,adjustthemowercuttingheightsothat  
the mower cuts off only the top one-third of the grass  
blades (See Fig. 11). For extremely heavy mulching,  
reduce your width of cut on each pass and mow slowly.  
Certaintypesofgrassandgrassconditionsmayrequire  
that an area be mulched a second time to completely  
hide the clippings. When doing a second cut, mow  
across or perpendicular to the first cut path.  
NOTE: Duringthisproceduretherewillbenomovementof  
drivewheels.Theairisbeingremovedfromhydraulicdrive  
system.  
•
•
Shut- off engine and set parking brake.  
Engage transmission by placing freewheel control in  
drivingposition(See“TOTRANSPORT”inthissection  
ofmanual).  
Sittinginthetractor seat,startengine.Aftertheengine  
is running, move throttle control to half (1/2) speed.  
Disengageparkingbrake.  
Drive tractor forward for approximately five feet then  
backwards for five feet. Repeat this driving procedure  
three times.  
•
•
•
•
•
•
Your tractor is now purged and now 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.  
Change your cutting pattern from week to week. Mow  
northtosouthoneweekthenchangetoeasttowestthe  
next week. This will help prevent matting and graining  
of the lawn.  
•
•
Thelefthandsideofmowershouldbeusedfortrimming.  
Drivesothatclippingsaredischargedontotheareathat  
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.  
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. 10).  
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  
desiredheight.

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.
