PURGING AIR FROM TRANSAXLE -

Air may become trapped in the inlet hydraulic filter or
closed loop passages of the hydro transaxle during

internal transaxle parts.

2. Place in the “PUSH” position.
3. Start the tractor engine and run at a low idle.
4. Move the ground speed control lever from the neutral
position to the full forward position for five seconds.
Move lever to the full reverse position for five sec-
onds. Repeat this procedure three times in forward
and reverse direction.
5. Return the control lever to the neutral gate.
6. Place the hydro release lever (A) in the “DRIVE” posi-
tion.
7. Drive the tractor at least five feet in the forward and
reverse directions with full throttle and full ground
speed. Repeat this procedure three times in the for-
ward and reverse directions.
8. Check oil level (if applicable)
Repeat the above steps if tractor has noisy or erratic
operation, lack of performance after transmission warm-
up, or oil leakage from the transaxle vent tube.
