1. Drive Speed/Torque Select
The forward position gives maximum drive
speed. The back position gives maximum
torque for rough terrain and climbing
grades. The center position allows the machine to be driven
as quietly as possible.
2. Steer Select
The action of the steering system is opera-
tor selectable. The center switch position
gives conventional front wheel steering
with the rear wheels unaffected. 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
close to 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 cir-
cle for maneuvering in confined areas.
