The intelligent HST dozer you mentioned, featuring the latest IMC 2.0 capabilities, introduces significant improvements to enhance productivity and operational efficiency. Here are some key features:

  • IMC 2.0 built-in features designed to increase productivity.
  • Increased overall travel speed with four speed presets for versatile operation.
  • Fast travel and steering response facilitated by the HST (Hydrostatic Transmission) drive.

Product Features and benefits:

Proactive Dozing Control

Empower operators, even those with less experience, with proactive dozing control. The dozer automatically cuts or strips from existing terrain, measuring the terrain it tracks over to plan the next pass. This innovative feature can boost productivity by up to 60% compared to the previous generation.

Automatic Fill Spreading

Lift layer control allows operators to effortlessly spread fill material from existing terrain with the press of a button. The dozer measures the tracked terrain, using the data to plan the next pass. Achieve up to double your production and ensure consistent layers for optimal compaction quality.

Efficient Material Leveling

Tilt steering control automatically tilts the blade to maintain straight travel during rough dozing, reducing operator steering input by up to 80%.

Quick Surface Creation

Enable operators to create a temporary design surface with the press of a button. Combined with other IMC 2.0 functions, your crew can initiate stripping or spreading using automated input while awaiting the finish grade model.

Closing the Operator Skill Gap

Machine logic enables the dozer to continuously learn the terrain, making calculated decisions for the next pass. Intelligent Machine Control (IMC) plays a crucial role in narrowing the skill gap between new and experienced operators.

Versatile 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 is applicable even without a 3D model.

Learning from Operator’s Input

Automatic functions endow the dozer with the ability to learn from the operator’s blade input, enhancing adaptability, easing operation, and reducing reliance on constant operator input.

Blade Response Excellence

Intelligent Machine Control (IMC) facilitates outstanding blade response for finish grading, enabling the dozer to anticipate grade transitions and adjust the blade angle accordingly.
