Komatsu Dozers D65EX-17
D65EX-17 Crawler Dozer
The D65EX-17 provides excellent production and economy at the same time. The Komatsu exclusive Sigma blade can produce 15% more than a conventional semi-U blade and the automatic transmission with lock-up torque converter can reduce fuel consumption by up to 15% over the previous model. To make the operator more comfortable and productive, a new air suspension heavy duty heated seat is standard. Hydrostatic steering (HSS) with a palm command control joystick gives the operator the ability to make smooth turns under full power.

| 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. |
