Proactive Dozing Control: With proactive dozing control, even less experienced operators can automatically cut or strip from existing terrain. The dozer measures the terrain it tracks over and utilizes the data to plan the next pass, improving productivity by up to 60% compared to the previous generation.
Automatic Spread of Fill Material: Lift layer control enables operators to spread fill from existing terrain with a simple button press. The dozer measures the terrain it tracks over, using gathered data to plan the next pass. This automated process can double production and achieve consistent layers for compaction quality.
Tilt Steering Control: 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: Operators can create a temporary design surface with the press of a button. Combined with other IMC 2.0 functions, the crew can initiate stripping or spreading using automated input while waiting for the finish grade model.
Closing the Operator Skill Gap: Machine logic enables the dozer to continuously learn the terrain and make calculated decisions for the next pass, helping reduce the skill gap between new and experienced operators.
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. This allows for automatic control even without a 3D model.
Machine Learning from Operator Input: Automatic functions empower the dozer to learn from the operator’s blade input, enhancing adaptability, simplifying operation, and reducing reliance on manual operator input.
Outstanding Blade Response for Finish Grading: Intelligent Machine Control (IMC) enables the dozer to anticipate grade transitions and adjust the blade angle accordingly, delivering exceptional grading performance.
