Komatsu America’s D51 EX/PX-22 crawler dozer offers a super-slant nose engine hood which provides the operator with exceptional visibility of the top blade edge and area in front of the dozer blade at all times. The super-slant-nose is a feature that allows the operator to see objects that are very close to the blade, dramatically increasing safety and efficiency on the jobsite. This new design assures an improvement in fundamental dozer work parameters. The D51EX-22 and D51PX-22 crawler dozers are mid-sized machines appropriate for work in construction, site preparation, home building, forestry, utility and quarry applications. Outfitted with Komatsu’s fuel efficient 6.69 Liter, Tier 3 emissions certified SAA6D107E-1 engine, these new models push with 130 HP at 2,200 RPM and range in operating weight from 27,778 to 28,881 lbs, depending on the version.
