PURGE TRANSMISSION
CAUTION: Never engage or disengage
freewheel lever while the engine is run ning.
To ensure proper operation and performance, it is rec om-
mend ed 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 vel-
oped during shipping of your tractor.
IMPORTANT: SHOULD YOUR TRANSMISSION RE QUIRE
REMOVAL FOR SERVICE OR REPLACEMENT, IT SHOULD
BE PURGED AFTER REINSTALLATION BEFORE OPERATING
THE TRACTOR.
1. Place tractor safely on a level surface - that is clear
and open - with engine off and parking brake set.
2. Disengage transmission by placing freewheel control
in freewheeling position (See “TO TRANSPORT” in
this section of manual).
3. Sitting in the tractor seat, start engine. After the engine
is running, move throttle control to slow position. With
motion control lever in neutral po si tion, slowly disengage
clutch/brake pedal.
CAUTION: At any time, during step 4, there
may be movement of the drive wheels.
4. Move motion control lever to full forward position and
hold for five (5) seconds. Move lever to full reverse
position and hold for five (5) seconds. Repeat this
procedure three (3) times.
5. Move motion control lever to neutral position. Shut- off
engine and set parking brake.
6. Engage transmission by placing freewheel control in
engaged position (See “TO TRANSPORT” in this sec-
tion of manual).
7. 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 position, slowly
disengage clutch/brake pedal.
8. 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 motion
control lever to the neutral position. Repeat this proce-
dure with the motion control lever three (3) times.
Your transmission is now purged and now ready for normal
op er a tion.
OPERATION
TO START ENGINE (See Fig. 15)
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.

Adjustments section of this manual.
