Its 11-liter engine, 14’ 4” straight tilt blade, and fuel-efficient automatic transmission make it ideal for soft ground conditions. Additionally, you have the option for an extended wear life undercarriage with 36” wide PLUS (Parallel Link Undercarriage System) rotating bushing track shoes.
- Engineered for powerful dozing capabilities.
- Excellent blade capacity for efficient operations.
- Quiet cab with a smooth ride and excellent visibility.
- Automated blade control with iMC for precise grading.
Product Features and benefits:
Custom Build Your Dozer: Choose from the D65/85/155 family of dozers, each offering exceptional power, economy, and reliability. Customize your dozer with various blade options (straight, Semi-U, Sigmadozer, and Full U for D155), track shoe width, and horsepower combo tailored to your specific application needs.
Minimize Fuel Use: Benefit from an advanced Tier 4 engine that combines power and fuel efficiency. An auto idle shutdown feature, adjustable from 5-60 minutes, further reduces fuel consumption and emissions.
Fight Operator Fatigue with Controls: Operators will appreciate the palm command electronic control joysticks designed to fit the natural shape of their hands. Easily switch between auto-shift or manual-shift modes with a single button push, ensuring precision and reducing fatigue during shifts.
Smooth, Powerful Handling: Experience smooth and powerful turns with the hydrostatic steering system. It efficiently transmits engine power to both tracks without interruption and minimizes turning radius with counter-rotation while in neutral.
Long-Lasting Undercarriage: Maximize the lifespan of your dozer with the Parallel Link Undercarriage System (PLUS). Featuring rotating bushings, it provides up to twice the life of conventional undercarriage systems without requiring pin and bushing turns.
Fuel-Efficient Power: Achieve maximum 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 to the transmission, enhancing drive train efficiency.
Intelligent Machine Control (iMC): Equip your dozer with iMC for automatic dozing, rough cut to finish grade operations. Dozers learn operator blade input and offer near-100% auto control in select situations, helping new operators quickly adapt and optimize performance.
Operator Comfort and Focus: Ensure operator comfort with an air suspension seat featuring lumbar support and tilt adjustment. Electric heat keeps operators comfortable in cold conditions, allowing them to stay focused and productive.
Situational Awareness: Enhance situational awareness with a standard rear camera monitoring system that displays the view behind the dozer on a large color monitor in the cab.
