•
•
Besuretheareaisclearofotherpeoplebeforemowing.  
Lookforthissymboltopointoutimportant  
safety precautions. It means CAUTION!!!  
BECOME ALERT!!! YOUR SAFETY IS IN-  
VOLVED.  
Stop machine if anyone enters the area.  
Nevercarrypassengersorchildrenevenwiththeblades  
off.  
Do not mow in reverse unless absolutely necessary.  
Alwayslookdownandbehindbeforeandwhilebacking.  
Nevercarrychildren. Theymayfalloffandbeseriously  
injured or interfere with safe machine operation.  
Keep children out of the mowing area and under the  
watchful care of another responsible adult.  
CAUTION: Do not coast down a hill in  
neutral, you may lose control of the trac-  
tor.  
•
•
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.  
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.  
CAUTION: Tow only the attachments  
that are recommended by and comply  
with specifications of the manufacturer  
of your tractor. Use common sense  
whentowing. Operateonlyatthelowest  
possible speed when on a slope. Too  
heavy of a load, while on a slope, is  
dangerous. Tires can lose traction with  
thegroundandcauseyoutolosecontrol  
of your tractor.

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)

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.

an engine warm-up period from several seconds to  
several minutes, depending on the temperature.  
•
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.  
IMPORTANT: WHEN OPERATING IN TEMPERATURES  
BELOW 32°F(0°C), USE FRESH, CLEAN WINTER GRADE  
GASOLINE TO HELP INSURE GOOD COLD WEATHER

AUTOMATIC TRANSMISSION WARM UP  
•
Beforedrivingtheunitincoldweather,thetransmission  
should be warmed up as follows:  
WARNING: Experienceindicatesthatalcoholblendedfuels  
(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. Drainthegastank,starttheengineandletitrununtil  
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.

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.

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

from the tank to the engine.  
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.

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.  
•
Avoidcuttingyour lawnwhen 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 and the newly cut area  
will not be exposed to the direct sun.  
•
Your tractor is now purged and now ready for normal  
operation.  
MOWING TIPS  
•
•
•
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.  
Change your cutting pattern from week to week. Mow  
northtosouthoneweekthenchangetoeasttowestthe  
next week. This will help prevent matting and graining  
of the lawn.  
•
Mower should be properly leveled for best mowing  
performance. See“TO LEVEL MOWER HOUSING” in  
the Service and Adjustments section of this manual.  
•
•
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.  
MAX 1/3  
•
•
Do not mow grass when it is wet. Wet grass will plug  
mowerandleaveundesirableclumps. Allowgrasstodry  
beforemowing.  
Alwaysoperateengineatfullthrottlewhenmowing  
to assure better mowing performance and proper dis-  
chargeofmaterial. Regulategroundspeedbyselecting  
a low enough gear to give the mower cutting perfor-  
mance as well as the quality of cut desired.
