Komatsu America introduces the D31EX-22 (pictured) and D31PX-22 crawler dozers. Equipped with Komatsu’s hydrostatic transmission, these machines are designed for work in general construction, site preparation, home building, forestry and utility applications. 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-certified Komatsu SAA4D95LE-5 engine, these new models push with a net horsepower of 78 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.
