OPERATION
TO START ENGINE (See Fig. 9)
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 (N) position.
• Move attachment clutch to “DISENGAGED” position.
• Move throttle control to fast position
• Pull choke control out for a cold engine start attempt.
For a warm engine start attempt the choke control may
not be needed.
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, push choke control in, wait a
few minutes and try again. If engine still does not start,
pull the choke control out and retry.
WARM WEATHER STARTING (50° F and above)
• When engine starts, slowly push choke control in until
the engine begins to run smoothly. If the engine starts to
run roughly, pull the choke control out slightly for a few
seconds and then continue to push the control in slowly.
• 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 and below)
• When engine starts, slowly push choke control in until
the engine begins to run smoothly. Continue to push
the choke control in small steps allowing the engine to
accept small changes in speed and load, until the choke
control is fully in. If the engine starts to run roughly, pull
the choke control out slightly for a few seconds and
then continue to push the control in slowly. This may
require an engine warm-up period from several sec onds
to several minutes, depending on the temperature.
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 neu tral.
Re lease the parking brake and let the clutch/brake
slowly return to operating po si tion.
• Allow one minute for transmission to warm up. This
can be done during the engine warm up period.
• The attachments can be used during the engine warm-
up period after the transmission has been warmed up
and may require the choke con trol be pulled out slight ly.
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
ADJUST CARBURETOR” in the Service and Ad just ments
section of this manual.
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.
