PURGE TRANSMISSION
_,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 disengaged posi-
tion (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 (N)
position, slowly disengage clutch/brake
pedal.
4. Move motion control lever to full for-
ward position and hold for five (5) sec-
onds. 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 park-
ing brake.
6. Engage transmission by placing free-
wheel control in engaged position (See
"TO TRANSPORT" 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 now
