1. Drive Speed/Torque Select
The machine has a two position
switch - The forward position
gives maximum drive speed. The
back position gives maximum
torque for rough terrain and
climbing grades.
2. Steer Select (If Equipped)
When equipped with four wheel steering, the
action of the steering system is operator
selectable. The center switch position gives
conventional front wheel steering with the rear wheels unaf-
fected. This is for normal driving at maximum speeds. The
forward position is for “crab” steering. When in this mode
both front and rear axles steer in the same direction, which
allows the chassis to move sideways as it goes forward. This
can be used for positioning the machine in aisle ways or
against buildings. The back switch position is for “coordi-
nated” steering. In this mode the front and rear axles steer in
the opposite directions to produce the tightest turning circle
for maneuvering in confined areas.
To re-synchronize the front and rear axles, position the rear
drive wheels to the forward drive position by selecting
either crab or compound steer, then select front steer (cen-
ter switch position) to operate the normal steering function.
