Product Features and benefits:
Custom Build the Dozer You Need: The D65/85/155 family of dozers offers exceptional power, economy, and reliability. Tailor your dozer with various blade options (straight, Semi-U, Sigmadozer, and Full U for D155), track shoe width, and horsepower combinations to suit your specific application.
Efficient Fuel Utilization: Benefit from an advanced Tier 4 engine that provides a powerful combination of performance and fuel efficiency. The auto idle shutdown, adjustable from 5-60 minutes, contributes to reduced fuel consumption and emissions.
Combat Operator Fatigue with Advanced Controls: Enhance operator comfort with palm command electronic control joysticks, designed to fit the natural relaxed shape of their hands. Auto-shift or manual-shift modes, easily selected with a button push, ensure precision and reduce fatigue during extended shifts.
Smooth and Powerful Handling: The hydrostatic steering system enables operators to execute smooth, powerful turns. It transmits engine power to both tracks without interruption, minimizing turning radius with counter-rotation while in neutral.
Long-Lasting Undercarriage for Maximum Efficiency: Maximize the lifespan of your dozer with the Parallel Link Undercarriage System (PLUS) featuring rotating bushings. This design delivers up to twice the life of conventional undercarriages, with even parts wear and longer intervals between replacements.
Fuel-Efficient Power for Maximum Work Efficiency: Achieve optimal work efficiency with a lock-up torque converter that determines the appropriate gear based on load and conditions. The lockup mechanism automatically transfers engine power directly to the transmission, boosting overall drive train efficiency.
Intelligent Machine Control (iMC): Equipped with iMC, these dozers offer automatic dozing, rough cut to finish grade capabilities. The machines “learn” operator blade input, allowing for near-100% auto control in select situations. iMC facilitates a quick learning curve for new operators.
Enhanced Operator Focus: Operators perform at their best when comfortable. The air suspension seat with lumbar support and tilt ensures operators can easily adjust to their preferences, with electric heat to keep them comfortable in cold conditions.
