Product Features and benefits:

  1. Closing the Operator Skill Gap:
    • The dozer employs machine logic that allows it to continuously learn the terrain, making calculated decisions for the next pass.
    • Intelligent Machine Control (IMC) is implemented to reduce the skill gap between new and experienced operators.
  2. Advanced Machine Control:
    • In specific situations such as auto stripping, rough dozing, spreading, and advanced finish grading, operators can choose nearly 100% machine control auto usage.
    • Automatic control can be applied even without having a 3D model, showcasing the versatility and automation capabilities of the dozer.
  3. Machine Learning Capability:
    • Automatic functions are integrated into the dozer, allowing it to learn from the operator’s blade input.
    • This learning capability enhances adaptability, simplifies operation, and reduces reliance on operator input.
  4. Outstanding Blade Response for Finish Grading:
    • IMC technology enables the dozer to anticipate grade transitions and alter the blade angle accordingly.
    • This results in unparalleled grading performance, showcasing precision and efficiency in finish grading operations.
