Komatsu Dozers D65WX-17
D65WX-17 Crawler Dozer
The wide track D65WX-17 has all the same great features as the D65 E and P machines but uses the standard length track of the EX with the wider track of the LGP PX. The D65WX gives the extra stability some applications such as slope work require without having to go to a low ground pressure shoe. The D65WX-17 can be equipped with the inside mount power angle tilt blade or the outside mount Sigma.

| 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. |
