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.
