control to the fast position.
The attachments and ground drive can

PURGE TRANSMISSION
To ensure proper operation and per-
for mance, it is rec om mend ed that the
trans mis sion be purged before operating
trac tor for the fi rst time. This procedure will
remove any trapped air inside the trans-
mis sion which may have de vel oped dur ing
shipping of your tractor.
IMPORTANT: Should your transmission
require removal for service or re place -
ment, it should be purged after re in stal l-
a tion before operating the tractor.
1. Place tractor safely in an area that is
at for approximately 80 feet in front of
the tractor and set the parking brake.
2. Sitting in the tractor seat, start en gine.
After the engine is running, move
throttle control to slow position. With
motion control lever in neutral (N)
po si tion, slowly disengage clutch/brake
pedal.
3. Slowly move motion control lever to
full forward position and hold for fi ve
(5) seconds, or approximately 40 feet.
Slowly move lever to full reverse posi-
tion and hold for fi ve (5) seconds, or
approximately 20 feet. After the tractor
moves approximately 20 feet in reverse
return the motion control lever to the
neutral (N) position. Repeat this proce-
dure three (3) times.
Your transmission is now purged and now
ready for normal operation.
AUTOMATIC TRANSMISSION WARM UP
Before driving the unit in cold weath er,
the trans mis sion 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 re turn
to operating po si tion.
3. Allow one minute for trans mis sion 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
trans mis sion 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 per for mance.
