PURGE TRANSMISSION
4_ CAUTION: Never engage or dis-
engage freewheel lever while the engine
is running.
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).

After the engine is running, move
throttle control to slow position. With

forward position and hold for five (5)
seconds. Move lever to full reverse

ward, after the tractor moves approxi-
mately five (5) feet, slowly move motion
control lever to reverse position. After
