Komatsu America's D65PXi-18 intelligent machine control system allows automated operation from heavy dozing to fine grading, achieving up to 8% greater efficiency in moving material, based on start-to-finish grade testing of typical aftermarket machine control systems.

The long track, low ground pressure D65PXi-18 introduced recently by Komatsu America Corp. was designed specifically for functionality in soft or wet conditions, offering improved stability for finish grading applications. It is powered by a 217-hp (162-kW) SAA6D114E-6 Tier 4 Final emissions certified engine.

An electronically controlled transmission on the D65PXi-18 locks up the torque converter to transfer engine power directly to the transmission, eliminating horsepower loss and cutting fuel consumption by up to 10%.

Highlights of the crawler dozer include next-generation intelligent machine control. “The machine senses blade load, minimizes track slip, and ensures operators get the most from every push,” said Jason Anetsberger, Komatsu product manager. “We believe the difference in dozing efficiency between conventional machine operation and intelligent machine control technology is exceptional.”

The intelligent machine control system on the D65PXi-18 allows automated operation from heavy dozing to fine grading, achieving up to 8% greater efficiency in moving material, based on start-to-finish grade testing of typical aftermarket machine control systems. By designing out blade-mounted sensors and components, operators no longer need to climb on the blade to install/remove GNSS antennas, eliminating the need to care for electrical connections. Komatsu emphasizes that by getting rid of such cables, and the climbing and connections common with aftermarket systems, operators save 15 minutes at the start and finish of each day. A 30-minutes-a-day savings for 20 days a month is 10 saved hours per month.

An automatic gearshift transmission and lock up torque converter selects the optimal gear range depending on jobsite conditions and load for maximum operation efficiency. This electronically controlled transmission locks up the torque converter to transfer engine power directly to the transmission, eliminating power loss and cutting fuel consumption by up to 10%.

D65PXi-18's ROPS (roll-over protection structure) certified, pressurized cab has wide, tall windows and properly sealed for increased visibility and less noise and dust inside the cab. The D65PXi-18 cab damper mounts isolate the cab from the machine frame, softening shocks and vibrations to the operator.
