Opt for the D85EX-18 if you require a larger, powerful dozer that remains cost-efficient. This model offers an 11-liter engine, a large-capacity power-pitch blade, a fuel-efficient automatic shift transmission, and an economical PLUS (Parallel Link Undercarriage System) rotating bushing undercarriage option.
- Engineered for powerful dozing
- Excellent blade capacity
- Quiet cab with a smooth ride and great visibility
- Automated blade control with iMC
Product Features and benefits:
Dozer Customization: Explore the D65/85/155 family of dozers, each offering exceptional power, economy, and reliability. Customize your dozer by selecting the blade type (straight, Semi-U, Sigmadozer, and Full U for D155), track shoe width, and horsepower combination tailored to your specific application.
Fuel Efficiency Features: Benefit from an advanced Tier 4 engine that provides a powerful yet fuel-efficient combination. An adjustable auto idle shutdown, ranging from 5-60 minutes, contributes to reduced fuel consumption and emissions.
Operator Fatigue Reduction: Combat operator fatigue with palm command electronic control joysticks designed to fit the natural relaxed shape of hands. Easily switch between auto-shift and manual-shift modes with a single button push, ensuring precision with less fatigue throughout a shift.
Smooth and Powerful Handling: Enable your operators to execute smooth, powerful turns with the hydrostatic steering system. This system transmits engine power to both tracks without interruption, minimizing turning radius with counter-rotation while in neutral.
Durable Undercarriage: Maximize the lifespan of your dozer with the Parallel Link Undercarriage System (PLUS). This system, featuring rotating bushings, delivers up to twice the life of conventional undercarriages, without the need for pin and bushing turns.
Fuel-Efficient Power for Optimal Work: Enhance 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 drive train efficiency.
Intelligent Machine Control (iMC): Experience automatic dozing, rough cut to finish grade with iMC-equipped machines. These dozers “learn” operator blade input, allowing for near-100% auto control in select situations. iMC facilitates quick adaptation, especially for new operators.
Operator Comfort: Prioritize operator comfort with an air suspension seat featuring lumbar support and tilt adjustment. Electric heat ensures operators stay comfortable even in cold conditions.
Situational Awareness: Enhance situational awareness with a standard rear camera monitoring system. The large color monitor in the cab displays the view behind the dozer, providing operators with crucial information for safe and efficient operation.
