New Komatsu D65EXi-18 Bulldozer for Sale Need an all-around workhorse designed for years of high productivity? The D65EXi-18 is tough to beat. A large capacity outside push frame semi-U blade helps make it the backbone of your dozer fleet and includes extended wear life undercarriage 24” PLUS (Parallel Link Undercarriage System) rotating bushing tracks.
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. |
