STEERING SYSTEM
Palm Command Control System (PCCS) joystick control for all
directional movements. Pushing the joystick forward results in
forward machine travel, while pulling it rearward reverses the
machine. Simply tilt the joystick to the left or right to make a turn.
Tilting the joystick fully to the left or right activates counter-rotation.
Hydrostatic Transmission (HST) eliminates steering clutches and
brakes, providing smooth powerful turns. Fully electronic control
enables smooth control. The PCCS utilizes shift buttons to increase
and decrease speed.

HYDROSTATIC TRANSMISSION
Dual-path, hydrostatic transmission provides infinite speed changes
up to
8.5 km/h
5.3 mph. The variable capacity travel motors allow
the operator to select the optimum speed to match specific jobs.
Travel control lock lever and neutral switch.
FINAL DRIVES
Two-stage planetary gear integrated into axial piston travel motors.
Compact in-shoe mount reduces risk of damage by debris. Bolt-on
sprocket for easy replacement.
