New Komatsu D39PXi-24 Bulldozer for Sale

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.

  • Get new operators up to speed quickly
  • Go from mass ex to finished grading faster than ever
  • Fully integrate 3D design data into your machines
  • Empower operators to work efficiently, pass after pass

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.

Advanced machine control: In select situations — auto stripping, rough dozing, spreading, advanced finish grading — operators can opt for nearly 100% machine control auto usage. They can even apply automatic control without having a 3D model.

A machine that learns from the operator: Automatic functions give the dozer the ability to learn from operator's blade input, resulting in more adaptability, easier operation and less reliance on operator input.

Outstanding blade response for finish grading: To deliver unparalleled grading performance, iMC enables the dozer to look ahead at grade transitions and alter the blade angle accordingly.
