Komatsu D31 Crawler Dozer

Komatsu’s Tier-3, 78-horsepower D31EX-22 and D31PX-22 crawler dozers share the super-slant nose and cab-forward design of the D51-22, and range in operating weight from 17,020 to 18,827 pounds. When the hydrostatic D31-22 dozers’ variable speed setting is selected, the operator can adjust ground speed through 20 increments using shift buttons on the travel joystick, or tiller. The Quick-Shift speed selection allows the operator to select three predetermined speed settings to match job conditions.
