New Komatsu D155AXi-8 Bulldozer for Sale Your big jobs demand a big dozer. 350+ horsepower, massive blade capacity with semi-U and full U blades, automatic lockup torque converter, and low drive K-bogie suspended undercarriage designed for maximum traction and smooth ride when dozing or ripping.
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: 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: 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: To deliver unparalleled grading performance, iMC enables the dozer to look ahead at grade transitions and alter the blade angle accordingly. |
