Product Features and benefits:
Closing the Operator Skill Gap
The incorporation of machine logic allows the dozer to continuously learn the terrain, enabling it to make calculated decisions for subsequent passes. Intelligent Machine Control plays a pivotal role in narrowing the skill gap between new and experienced operators.
Advanced Machine Control
In specific scenarios such as auto stripping, rough dozing, spreading, and advanced finish grading, operators have the option to choose nearly 100% machine control auto usage. This includes the ability to apply automatic control without the necessity of a 3D model.
Adaptive Learning
Automatic functions empower the dozer to learn from the operator’s blade input. This results in increased adaptability, simplified operation, and reduced dependence on constant operator input.
Exceptional Blade Response for Finish Grading
The Integrated Machine Control (IMC) system ensures an outstanding blade response for finish grading. By anticipating grade transitions, the dozer can proactively alter the blade angle, delivering unparalleled grading performance.
