NEUTRAL ADJUSTMENT(See Fig. 22)

The motion control lever has been pre set at the factory and

adjustment bolt.

• Move motion control lever to the neutral (N) (lock gate)

position.

bolt, move mower deck height to the lowest position.

After above adjustment is made, if the tractor still creeps
forward or backward while motion control lever is in neutral

• Loosen the adjustment bolt.
• Move the motion control lever 1/4 to 1/2 inch in the

direction it is trying to creep.

•      Tighten adjustment bolt securely.

The front wheel toe-in and camber are not adjustable on
your tractor. If damage has occurred to affect the front
wheel toe-in or camber, contact your nearest authorized
service center/department.
