2025 Komatsu Dozers D155AX-8

Torque converter dozers for your heavy jobs

Your big jobs demand a big dozer. 350+ horsepower, massive blade capacity with semi-U and full U blades, automatic lockup torque converter, and low drive K-bogie suspended undercarriage designed for maximum traction and smooth ride when dozing or ripping.

Features may include:

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.
