7. Fuel-efficient crawler dozer
Komatsu America’s D51 EX/PX-24 crawler dozer has an updated 131-hp Tier 4f engine and an electronically-controlled hydrostatic transmission that combine to cut fuel consumption by 13% versus prior models, and offer excellent maneuverability. A triple-labyrinth final drive housing design with debris shields provides additional protection to the final-drive floating seals.
