Looking for a larger and powerful yet cost-efficient dozer? The D85EXi-18 is an excellent choice. Its features include an 11-liter engine, a large-capacity power-pitch blade, a fuel-efficient automatic shift transmission, and an economical PLUS (Parallel Link Undercarriage System) rotating bushing undercarriage option.

  • Quick training for new operators
  • Efficient transition from mass excavation to finished grading
  • Seamless integration of 3D design data
  • Empowered operators for efficient and consistent performance

Product Features and benefits:

Advanced Machine Control

The dozer features machine logic that continuously learns the terrain, making calculated decisions for the next pass. Intelligent Machine Control (IMC) significantly reduces the skill gap between new and experienced operators.

Nearly 100% Machine Control Auto Usage

In specific situations like auto stripping, rough dozing, spreading, and advanced finish grading, operators can opt for nearly 100% machine control auto usage. This includes the application of automatic control without the need for a 3D model.

Machine Learning from Operator Input

Automatic functions empower the dozer to learn from the operator’s blade input. This results in increased adaptability, easier operation, and reduced reliance on direct operator input.

Outstanding Blade Response for Finish Grading

Intelligent Machine Control (IMC) ensures exceptional blade response for finish grading. The dozer can anticipate grade transitions, allowing it to alter the blade angle accordingly and deliver unparalleled grading performance.
