in “Mule Drive Belt Removal” section (page
31).

the steering lever is in swing-out position (neu-
tral), adjustment is required.

wheels are off the ground.
2. Make sure parking brake is released.
3. Remove linkage rod (item 4) and damper
(item 34) from hydro pump control arm

4. Place steering levers in the neutral swing-out
position and start engine.
5. If either of the drive wheels turn, proceed
with the following adjustment.
6. Loosen locking nut (item 16) and rotate
