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 left to make a left turn. Tilt it to the right for a right turn.    
Hydrostatic Steering System (HSS) is powered by steering planetary units and a hydraulic pump and motor. Counter-rotation turns are also available. Wet, multiple-disc, pedal-controlled service brakes are spring-actuated and hydraulically released. Gear shift lock lever also applies parking brake.    
     
Minimum turning radius:    
D65EX-17 6'3" 1.9 m

Undercarriage    
     
Suspension   Oscillating equalizer bar and pivot shaft
Track roller frame   Monocoque, large section, durable construction

Track shoes   Parallel Link Undercarriage System (PLUS) with lubricated rotating bushings for extended system wear life and lower maintenance costs. Track tension is easily adjusted with grease gun.
Final Drives    
     
Double-reduction final drive of spur and planetary gear sets to increase tractive effort and reduce gear tooth stresses for long final drive life. Segmented sprocket teeth are bolt-on for easy replacement.    
     
Hydraulic System    
     
Closed-center load sensing system (CLSS) designed for precise and responsive control, and for efficient simultaneous operation.
