Final drive
Steering system
Palm Command Control System (PCCS) lever controls for all directional movements. Pushing the PCCS lever forward results in forward machine travel, while pulling it rearward
reverses the machine. Simply tilt the PCCS lever to the left for a left turns, tilt it right for right turns.
Hydrostatic Steering System (HSS) power has been increased 25% by a larger HSS motor, greater hydraulic pump flow, and more engine power while steering. The result is more powerful turns and quicker counter-rotation. Wet, multiple-disc, pedalcontrolled service brakes are spring-actuated and hydraulically released. Gear shift lock lever also applies parking brake.
