Acquire the versatile “Swiss Army knife” of dozers designed to adapt effortlessly to various situations, from golf course construction to highway projects. Specifically crafted for precise, high-speed grading, its standard parallel link undercarriage system incorporates rotating bushings, reducing undercarriage wear, particularly during high-speed reverse travel. The Tier 4 Final engine and electronically controlled hydrostatic transmission ensure remarkably low fuel consumption for a dozer of this power. The high-capacity, high-wear-resistant, HST dozer blade is engineered to efficiently move massive loads with speed and precision.
- Efficiently train new operators.
- Accelerate from mass excavation to finished grading rapidly.
- Seamlessly integrate 3D design data into your machines.
- Empower operators for efficient and consistent performance, pass after pass.
Product Features and benefits:
Learns as it Works: Utilizing proactive dozing control, even operators with less experience can automatically cut/strip from existing terrain. The dozer assesses the tracked terrain, using the gathered data to plan the next pass, potentially improving productivity by up to 60% compared to the previous generation.
Spreads Fill Material Automatically: With lift layer control, operators can effortlessly spread fill from existing terrain with the press of a button. The dozer measures the tracked terrain, using the data to plan the next pass, aiming for increased production and consistent layers for compaction quality.
Levels Material Even During Rough Dozing: 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.
Close the Operator Skill Gap: Machine logic enables the dozer to continuously learn the terrain, making calculated decisions for the next pass. Intelligent Machine Control helps bridge the skill gap between new and experienced operators.
Advanced Machine Control: In select situations—auto stripping, rough dozing, spreading, advanced finish grading—operators can choose nearly 100% machine control auto usage, even applying automatic control without a 3D model.
A Machine that Learns from the Operator: Automatic functions grant the dozer the ability to learn from the operator’s blade input, resulting in increased adaptability, easier operation, and reduced reliance on operator input.
Outstanding Blade Response for Finish Grading: To deliver unmatched grading performance, IMC enables the dozer to anticipate grade transitions and alter the blade angle accordingly.
