Product Features and benefits:
Customizable Configuration: Construct the ideal dozer for your specific requirements within the D65/85/155 family. Choose from a selection of blades, including straight, Semi-U, Sigmadozer, and Full U (exclusive to D155). Tailor the track shoe width and horsepower combination to optimize performance for your application.
Fuel Efficiency at Its Best: Benefit from an advanced Tier 4 engine that strikes a perfect balance between power and fuel efficiency. The auto idle shutdown feature, adjustable from 5-60 minutes, contributes to reduced fuel consumption and emissions.
Combat Operator Fatigue: Prioritize operator comfort with palm command electronic control joysticks designed to fit the natural, relaxed shape of their hands. Easily switch between auto-shift and manual-shift modes with a simple button push, ensuring precision with reduced fatigue throughout the shift.
Effortless Handling with Hydrostatic Steering: Enable smooth and powerful turns with the hydrostatic steering system, transmitting engine power to both tracks without interruptions. Minimize turning radius with counter-rotation while in neutral, enhancing overall maneuverability.
Durable Undercarriage for Extended Life: Maximize the lifespan of your dozer with the Parallel Link Undercarriage System (PLUS), featuring rotating bushings. Enjoy up to twice the longevity compared to conventional undercarriages, with even wear on parts, eliminating the need for frequent replacements.
Optimize Work Efficiency with Lock-Up Torque Converter: Achieve peak work efficiency by incorporating a lock-up torque converter. This system intelligently selects the appropriate gear based on load and conditions, automatically transferring engine power to the transmission and enhancing overall drivetrain efficiency.
Intelligent Machine Control (iMC): Improve productivity with automatic dozing, rough cut to finish grade capabilities. iMC-equipped dozers learn operator blade input, allowing for near-100% auto control in select situations. This technology aids new operators in quickly mastering the machine.
Operator-Centric Comfort Features: Ensure your operators stay focused and comfortable with an air suspension seat equipped with lumbar support and tilt adjustment. Electric heating capabilities provide additional comfort in colder conditions.
Experience the epitome of power, efficiency, and operator comfort with our customizable dozers designed for enduring high productivity.
