New D71-24 dozer from Komatsu

Komatsu D71EX-24.

Komatsu’s new D71EX-24/PX-24 has a distinctive slant nose design and is one of the most powerful hydrostatic transmission (HST) dozers in its size class. Komatsu says the dozer is effective at grading, pushing, side-cutting and work on soft ground, giving users the flexibility to move from production to finishing with a single machine.

Pushing with 237 horsepower, Komatsu’s largest HST dozer (49,825 pounds to 52,910 pounds) helps operators maintain ground speed while operating under heavy loads in H mode.

The slant-nosed HST dozer is also available with Komatsu’s latest intelligent Machine Control (iMC) 2.0 capabilities:

  • Lift layer control optimizes earthwork productivity with the press of a button. It maintains compaction quality by automatically controlling lifts to the desired height. Excess fill is eliminated as automatic blade control follows the finish surface once lifts have reached finished grade.
  • Tilt steering control automatically tilts the blade to maintain straight travel during rough dozing. Reduces operator steering input by up to 80 per cent.
  • Operators can create a temporary design surface with the press of a button with quick surface creation. Combined with other iMC 2.0 functions, crews can begin stripping or spreading using automated input while waiting for the finish grade model.
  • With proactive dozing control, even 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, improving productivity by up to 60 per cent versus previous generation machines.
