Komatsu America offers the D37EX-22 and D37PX-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 D37EX-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 SAAD95LE-5 engine, these new models push with a net horsepower of 89 HP at 2,200 RPM and range in operating weight from 17,394 to 19,070 pounds, depending on the machine version.
