OPERATION
CAUTION: Alcohol blended fuels (called gas o hol
or using ethanol or methanol) can attract moisture
which leads to sep a ra tion and for ma tion 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
stor age 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 sea son.
See Storage in struc tions for additional information.
Never use engine or carburetor cleaner products
in the fuel tank or permanent damage may occur.
TO START ENGINE (See Fig. 4)
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.
•
Be sure freewheel control is in the transmission en gaged
position.
• Sit on seat in operating position, depress clutch/brake
pedal and set parking brake.
• Place motion control lever in neutral position.
• Move attachment clutch to “DISENGAGED” position.
• Move throttle control to choke position.
NOTE: Before starting, read the warm and cold starting
procedures below.
•
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
sec onds 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.
WARM WEATHER STARTING (50°F/10°C 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.
COLD WEATHER STARTING (50°F/10°C 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 position. This may
require an engine warm-up period from several seconds
to several minutes, depending on the tem per a ture.
AUTOMATIC TRANSMISSION WARM UP
• Before driving the unit in cold weather, the trans mis sion
should be warmed up as follows:
• Be sure the tractor is on level ground.
• Place the motion control lever in neutral.
Re lease the parking brake and let the clutch/brake
slowly return to operating position.
• Allow one minute for transmission to warm up. This
can be done during the engine warm up period.
• The attachments can also be used during the engine
warm-up period after the transmission has been warmed
up.
NOTE: If at a high altitude (above 3000 feet) or in cold
temperatures (below 32° F /0°C) 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.
MOWING TIPS
• Tire chains cannot be used when the mower hous ing
is attached to tractor.
• Mower should be properly leveled for best mowing
performance. 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 tractor. This will result in a more even dis tri bu tion
of clippings and more uniform cutting.
• 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. 15).
• 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 ensure better mowing performance and proper
dis charge of material. Regulate ground speed by
se lect ing a low enough gear to give the mower cut ting
per for mance 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 at tach ment being used.
CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.
IMPORTANT: WHEN OPERATING IN TEMPERATURES BELOW
32°F/0°C, USE FRESH, CLEAN WINTER GRADE GAS O LINE
TO HELP ENSURE GOOD COLD WEATHER START ING.
