OPERATION
BEFORE STARTING THE ENGINE
CHECK ENGINE OIL LEVEL
The engine inyour tractor has been shipped, from the
factory, already filled with summer weight oil.
Check engine oil with tractoron level ground.
Unthreed and remove oilfill cap/dipstick; wipe oil off.
Reinsert the dipstickintothe tube and restoilfill cap on
thetube. Do not threadthe cap ontothe tube. Remove
and read oil level. If necessary, add oil until =FULL"
mark on dipstick is reached. Do not overfill.
For cold weather operation you should change oil for
easier starting (See "OIL VISCOSITY CHART" in the
Customer Responsibilities section of this manual).
To change engine oil, see the Customer Responsibili-
ties section in this manual.
ADD GASOLINE
Fill fuel tank. Use fresh, clean, regular unleaded
gasoline witha 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
STARTING.
WARNING: Experience indicatesthatalcohol blendedfuels
(called gasohol or using ethanol or methanol) can attract
moisture which leads to separation and formation ofacids
during storage. Acidicgas can damage the fuel system of
an engine while in storage. To avoid engine problems, the
fuel system should be emptied before storage of30 days or
longer. Drainthe gastank, starttheengine and letitrununtil
the fuel linesand carburetor are empty. Use fresh fuel next
season. See Storage Instructionsforadditional information.
Never use engine or carburetor cleaner products inthe fuel
tank or permanent damage may occur.
CAUTION: Fill to bottom of gas tank I
filler neck. Do not overfill. Wipeoffany
I
spilled oil or fuel. Do not store, spill or
use gasoline near an open flame.

position.
Siton seat in operating position, depress clutch/brake
pedal and set parking brake.
Place motion controllever inneutral (N) position.
Move attachment clutch to =DISENGAGED" position.
Move throttle controlto choke position.
NOTE: Before starting, read the warm and cold starting
proceduresbelow.
Insert key into ignition and tum 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. Ifthe 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 positionand retry.
WARM WEATHER STARTING (50° F and above)
When engine starts, movethe throttlecontroltothe fast
position.
The attachments and ground drivecan now be used. If
the engine does notaccept the load, restart the engine
and allow it to warm up for one minute usingthe choke
as described above.
COLD WEATHER STARTING ( 50° F AND BELOW)
When engine starts, allow engine to run withthethrottle
control in the choke position until the engine runs
roughly,then move throttlecontrol to fast position. This
may require an engine warm-up peried from several
secondsto several minutes, depending onthe tempera-
ture.
AUTOMATIC TRANSMISSION WARM UP
Before ddvingthe unitincold weather, the transmission
should be warmed up as follows:
Be sure the tractor ison level ground.
Place the motion control lever in neutral. Release
the parking brake and let theclutch/brake s Io w Iy

up.
NOTE: If at a high altitude (above 3000 feet) or in cold
temperatures (below 32 F) the carburetor fuel mixturemay
need to be adjusted for best engine performance. See "TO
ADJUST CARBURETOR" in the Service and Adjustments
section ofthis manual.
PURGE TRANSMISSION
[_lb AUTION: Neverengageordisengage I
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 bevel-
oped 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.
Place tractor safely on level surface with engine off and
parking brake set.
Disengage transmission by placing freewheelcontrol in
freewheeling position (See "TO TRANSPORT" in this
