  • Fully integrate 3D design data into your machines
  • Empower operators to work efficiently, pass after pass

Features and benefits

Close the operator skill gap

Close the operator skill gap

Machine logic allows the dozer to continuously learn the terrain and make calculated decisions for the next pass. Intelligent Machine Control helps lessen the skill gap between new and experienced operators.

Advanced machine control

Advanced machine control

In select situations — auto stripping, rough dozing, spreading, advanced finish grading — operators can opt for nearly 100% machine control auto usage. They can even apply automatic control without having a 3D model.

A machine that learns from the operator

A machine that learns from the operator

Automatic functions give the dozer the ability to learn from operator's blade input, resulting in more adaptability, easier operation and less reliance on operator input.

Outstanding blade response for finish grading

Outstanding blade response for finish grading

To deliver unparalleled grading performance, IMC enables the dozer to look ahead at grade transitions and alter the blade angle accordingly.

  • Steering system features: Palm Command Control System (PCCS) lever controls for all directional movements. Pushing the PCCS lever forward results in forward machine travel, while pulling it rearward reverses the machine. Simply tilt the PCCS lever to the left for a left turns, tilt it right for right turns. Hydrostatic Steering System (HSS) power has been increased 25% by a larger HSS motor, greater hydraulic pump flow, and more engine power while steering. The result is more powerful turns and quicker counter-rotation. Wet, multiple-disc, pedalcontrolled service brakes are spring-actuated and hydraulically released. Gear shift lock lever also applies parking brake.
