If you need the “Swiss Army knife” of dozers that can adapt easily to multiple situations — from golf course construction to highway projects — this dozer is it. Built for precise, high-speed grading, its standard parallel link undercarriage system features rotating bushings, which help reduce undercarriage wear especially while traveling in reverse at high speeds. The Tier 4 Final engine and electronically controlled hydrostatic transmission keep fuel use remarkably low for a dozer this powerful. And the high capacity, high-wear-resistant, HST dozer blade is engineered to move massive loads quickly and efficiently.

Palm Command Control System (PCCS) joystick control for all directional movements. Pushing the joystick forward results in forward machine travel, while pulling it back reverses the machine. Simply tilt the joystick to the left or right to make a turn. Tilting the joystick fully to the left or right activates counter-rotation.
Hydrostatic Transmission (HST) provides smooth, powerful turns. Fully electronic control enables smooth control that can be adjusted in the monitor. The PCCS utilizes shift buttons to increase and decrease speed.
Minimum turning radius* | 2.4 m |
*As measured by track marks on the ground at pivot turn.
