Komatsu America Corp. - D65EX-17 Crawler Dozers

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.
