Komatsu America’s KomStat II line of dozers the D31EX/PX-21, D37EX/PX-21 and D39EX/PX-21 – come equipped with the company’s Electronic Control Hydrostatic Transmission and Palm Command Control System. Allowing for variable or intermediate speed selection, the transmission gives you 20 increments of spend adjustment, while the intermediate speed selection provides three distinct ranges. Both modes allow you to properly match the machine’s dozing speed to jobsite conditions. The dozers also have adjustable reverse speed control that allows the machines to reverse either slower or faster than the chosen forward dozing speed. The transmission consists of a dual-path, closed-circuit system with two variable displacement piston pumps and two three-speed variable displacement travel motors.
