Previewed at MINExpo, the dozer features a Tier 4 Final SAA6D170E engine capable of 775 hp in reverse, which reportedly is an improvement of 20% over the prior model. The engine requires no Selective Catalytic Reduction (SCR) system and features the Variable Geometry Turbocharger, Dual Komatsu Diesel Particulate Filters, large capacity and high efficiency EGR coolers, and the Komatsu Closed Crankcase Ventilation filter.

Reported performance enhancements available in 2017 include machine guidance and fully integrated blade control; remote control; undercarriage, cab mount, seat and door modifications; extended track frame and mainframe life; single link blade support and larger trunnion; and improved visibility.

The dozer cuts downtime and increases production through rough-to-finish automatic dozing, and by eliminating the need to install and remove blade-mounted sensors each day. Additionally, operators benefit from improvements to overall comfort and “are empowered with more data and more automated capabilities than ever before in a mining-class Komatsu dozer,” said Jason Anetsberger, senior product manager.
