Komatsu America Corp. introduces the D31EX-22 and D31PX-22 crawler dozers. Equipped with Komatsu's proven Hydrostatic Transmission (HST) these machines are designed for work in general construction, site preparation, home building, forestry and utility applications. Building on the successful design of the D51-22 dozer series, the D31EX-22 machines feature a super-slant nose coupled with a new cab forward design that moves the operator closer to the blade while improving machine balance, ride and stability.

Outfitted with a fuel efficient 3.26 Liter, EPA Tier 3 emissions certified Komatsu SAA4D95LE-5 engine, these new models push with a net horsepower of 78 HP at 2,200 RPM and range in operating weight from 17,020 to 18,827 pounds, depending on the machine version. With 86 inches of track on the ground both standard (EX) and low ground pressure (PX) models offer customers weight distribution and flotation options to best match their application.

The D31-22 steering system provides smooth agile movement when dozing, even in gradual turns, permitting the operator to approach dozing objects accurately in corner grading and sidewall operations. The D31-22 dozers employ a large power angle tilt blade with a capacity of 2.09 yd3 to 2.11 yd3, which results in more material staying on the blade and making it a more productive machine.

The new dozer is equipped with the latest KOMTRAX
