Steering System

PCCS joystick control for all directional movements. Pushing

the joystick forward results in forward machine travel, while

pulling it backward 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. 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.
