2025 Komatsu Dozers D39PXi-24

Powerful, versatile and yes, nimble

If you want a dozer that’s equally at home performing heavy site prep and accurate fine work, this model is an excellent choice. Powered by a fuel efficient, environmentally friendly EPA Tier 4 Final certified engine, it offers your operators a quiet, comfortable cab that provides unrivaled blade visibility. It’s engineered to get jobs done quickly and accurately with its outstanding blade response, fast work equipment speed, an additional “fast-blade mode” that boosts blade speed for high-speed grading, and surprising maneuverability via full power to both tracks during turns or counter rotation steering.

Features may include:

Learns as it works
  • With proactive dozing control, even your less experienced operators can automatically cut/strip from existing terrain. The dozer measures the terrain it tracks over and uses that data to plan the next pass. Can improve productivity by up to 60% versus previous generation.
Spreads fill material automatically
  • Lift layer control automatically lets your operators spread fill from existing terrain with the press of a button. The dozer measures the terrain it tracks over and uses the data it gathers to plan the next pass. Attain up to double your production and achieve consistent layers for compaction quality.
Levels material even during rough dozing
  • Tilt steering control automatically tilts the blade to maintain straight travel during rough dozing. Reduces operator steering input by up to 80%.
Quick surface creation
  • Operators can create a temporary design surface with the press of a button. Combined with other IMC 2.0 functions, your crew can begin stripping or spreading using automated input while waiting for the finish grade model.
Close the operator skill gap
  • Machine logic allows the dozer to continuously learn the terrain and make calculated decisions for the next pass. Intelligent Machine Control helps lessen the skill gap between new and experienced operators.

  • Final drive: In-shoe mounted, axial-piston-type travel motors, with integrated two-stage planetary gear reduction. Compact, in-shoe mount reduces risk of damage by debris. Bolt-on sprocket ring with triple labyrinth seal design.
  • Palm Command Control System (PCCS) joystick control for all directional movements. Pushing the joystick forward results in forward machine travel, while pulling it back reverses the machine. Simply tilt the joystick to the left or right to make a turn. Tilting the joystick fully to the left or right activates counter-rotation. Hydrostatic Transmission (HST) provides smooth, powerful turns. Fully electronic control enables smooth control that can be adjusted in the monitor. The PCCS utilizes shift buttons to increase and decrease speed.
