Introduction
The steering on the RZT-S mower works in two phases.
•
First it steers like any other riding mower by turning the front wheels.
•
Second and more importantly, the steering linkage controls the drive output of the two Hydro-Gear trans-
missions.
The steering shaft has a pinion gear that drives a pair of segment gears. When the steering wheel is turned, the
segment gears turn the front wheels. The segment gears also control the drive speed of the rear wheels. When turn-
ing, the inside drive wheel is slowed more than the outside drive wheel. When the inside front wheel reaches an
angle of 90
o
,
the rear wheel on that side will stop driving. Turning the wheel past that point will make the inside rear
wheel drive in reverse. The inside front wheel can reach a 108
o
angle. The mower will then make a zero radius turn.
Because the segment gears are linked to the transmissions, the transmission adjustments and the wheel align-
ment must be done together. A transmission that is out of adjustment can make the steering react as if it is out of
adjustment just as a steering linkage that is out of adjustment will affect the transmissions.
