When you require a robust yet cost-efficient dozer, the D85EXi-18 stands out as an excellent choice. Boasting an 11-liter engine, a large-capacity power-pitch blade, and a fuel-efficient automatic shift transmission, this dozer is designed to tackle demanding tasks with ease. The economical PLUS (Parallel Link Undercarriage System) with rotating bushings further adds to its efficiency.
- Rapid Operator Training: The dozer is engineered to get new operators up to speed quickly, ensuring a smooth transition for your team.
- Accelerated Grading Processes: Seamlessly transition from mass excavation to finished grading at an unprecedented pace, increasing overall project efficiency.
- Advanced 3D Design Integration: Fully integrate 3D design data into the machine, enhancing precision and accuracy in every pass.
- Empower Operators: Equip your operators to work efficiently, pass after pass, with features that enhance control, responsiveness, and overall productivity.
Product Features and benefits:
- Closing the Operator Skill Gap:
- Machine logic enables continuous learning of the terrain, allowing the dozer to make calculated decisions for the next pass.
- Intelligent Machine Control (IMC) technology helps bridge the skill gap between new and experienced operators.
- Advanced Machine Control:
- In select situations such as auto stripping, rough dozing, spreading, and advanced finish grading, operators can choose nearly 100% machine control auto usage.
- Automatic control is available even without a 3D model, providing flexibility in various applications.
- Learning from the Operator:
- Automatic functions give the dozer the ability to learn from the operator’s blade input.
- This results in increased adaptability, easier operation, and reduced reliance on operator input.
- Outstanding Blade Response for Finish Grading:
- The Intelligent Machine Control (IMC) system enables the dozer to look ahead at grade transitions.
- The system can alter the blade angle accordingly, delivering unparalleled grading performance.
