ADJUSTMENTS
Transmission Control
IMPORTANT: The proper adjustment of the transax-
le control stops is essential for efficient operation
and life of the transaxle. These stops are properly
adjusted at the factory and should only require read-
justment if the transaxle or related control linkage is
removed or changed.
NOTE: It would not be unusual for a new machine,
after initial 5 or 10 hours of operation, to begin to not
travel straight (this is due to the break-in of the tran-
saxles).
Steering Lever Position Adjustment - Step 1
NOTE: For proper operation, the steering levers
should be adjusted to sit evenly using the following
procedure.
1. Examine the steering levers to make sure they
are parallel front to back in relation to one an-
other. If they are not equal, adjust accordingly.
(The handles may or may not be even at this
point.)
NOTE: The LH steering lever is non-adjust-
able. This procedure will require adjustment of
the RH lever to make it even with the LH lever.
Lever Alignment
2. Adjust the position of the RH lever by turning the
stop bolt in the Speed Control Actuator in or out.
Turning the stop bolt in will make the RH lever
move back, and turning it out will make it move
forward. Tighten the lock nut.

Steering Handles Adjustment - Step 2
1. An adjustment range of approximately 3 inches
is available on the steering handles - the han-
dles can be adjusted forward or aft depending
on the arm length of the operator. The handles
can be adjusted by loosening the lock nut at the
pivot point and the lock nut holding the handle in
position in the adjustment slide. Adjust the han-
dles into the most comfortable position and
tighten both lock nuts.
Levers should sit
parallel to each other
