WARM WEATHER STARTING (50° F and
above)
7. 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 and
below)
7. 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 temperature.
AUTOMATIC TRANSMISSION WARM UP
Before driving the unit in cold weather,
the transmission should be warmed up as
follows:
1. Be sure the tractor Is on level ground.
2. Place the motion control lever in
neutral. Release the parking brake
and let the clutch/brake slowly return
to operating position.
3. Allow one minute for transmission to
warm up. This can be done during
the engine warm up period.
• The attachments can also be used dur­
ing 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)
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.)
PURGE TRANSMISSION
A c AUTION: Never engage or disengage
freewheel lever while the engine is run­
ning.
To ensure proper operation and per­
formance, it is recommended that the
transmission be purged before operating
tractor for the first time. This procedure will
remove any trapped air inside the trans­
mission which may have developed during
shipping of your tractor.
IMPORTANT: Should your transmission
require removal for service or replace­
ment, it should be purged after reinstall­
ation before operating the tractor.
1. Place tractor safely on level surface
with engine off and parking brake set.
2. Disengage transmission by placing
freewheel control in “transmission dis­
engaged” position (See “TO TRANS­
PORT” 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 (N)
position, slowly disengage clutch/brake
pedal.
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.
NOTE: During this step there will be no
movement of drive wheels. The air is being
removed from hydraulic drive system.
5. Move motion control lever to neutral
(N) position. Shutoff engine and set
parking brake.
6. Engage transmission by placing
freewheel control in “transmission
engaged” position (See “TO TRANS­
PORT” in this section 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 (N)
position, slowly disengage clutch/brake
pedal.
8. Slowly move motion control lever for­
ward, after the tractor moves approxi­
mately five (5) feet, slowly move motion
control lever to reverse position. After
the tractor moves approximately five
(5) feet return the motion control lever
to the neutral (N) position. Repeat this
procedure with the motion control lever
three (3) times.
Your transmission is now purged and
ready for normal operation.
