New Komatsu D155PX-8 LGP Bulldozer for Sale For pushing massive loads on soft ground, the D155PX-8 LGP (low ground pressure). An 8-roller undercarriage with track shoe size up to 38” (965 mm) wide for outstanding traction and balance with exceptional floatation. Optional extended wear life undercarriage with 34” wide PLUS (Parallel Link Undercarriage System) rotating bushing track shoes available.
Custom build the dozer you need: All the dozers in the D65/85/155 family offer you outstanding power, economy and reliability. Customize yours with the blade (straight, Semi-U, Sigmadozer and Full U (D155 only)), track shoe width and horsepower combo best suited to your particular application. Helps minimize fuel use: An advanced Tier 4 engine offers you a potent combo of power and fuel efficiency. An auto idle shutdown, adjustable from 5-60 minutes, also helps cut fuel use and emissions. Controls help fight operator fatigue: Operators will enjoy the palm command electronic control joysticks that fit the natural relaxed shape of their hands. Auto-shift or manual-shift modes are easily selected with one push of a button for precision with less fatigue over the course of a shift. Smooth, powerful handling: Your operators can execute smooth powerful turns with the hydrostatic steering system. It transmits engine power to both tracks without power interruption and minimizes turning radius with counter-rotation while in neutral. Long-lasting undercarriage: Get the most from your dozer. The Parallel Link Undercarriage System (PLUS) with rotating bushings delivers up to twice the life of our conventional undercarriage with no pin and bushing turn required. Parts wear evenly and last longer before needing replacement. Work with fuel-efficient power: Seek maximum work efficiency with a lock-up torque converter. It determines the appropriate gear based on load and conditions. The lockup mechanism then automatically transfers engine power directly to the transmission, helping boost drive train efficiency. Help operators stay focused: Your operators perform best when they’re comfortable. That’s why they’ll love the air suspension seat with lumbar support and tilt. It’s easy for them to adjust to suit their needs, and electric heat helps them stay comfortable in the cold. Situational awareness: A standard rear camera monitoring system displays the view behind the dozer on the large color monitor in the cab. No-hassle DPF regeneration: Tier 4 machines use diesel particulate filters to burn off engine soot via regeneration. To help make sure it rarely impacts your operation, all D65/D85/D155 models use continuous passive regeneration, and active regeneration that typically doesn’t require the dozer to stop. Efficient blade pitch operation: Pressing the auto-pitch switch* lets the operator toggle blade pitch position from dig to dump with no lever movements. The blade pitch control can be set to automatically return to the digging position when reverse is selected. * Requires dual tilt dozer Ergonomic ripper controls: Operators will love the ergonomic ripper control lever that incorporates an auto-return function. It automatically raises the ripper so they can stop grappling with levers and focus on other tasks. It kicks in when travel lever is moved to reverse. |
