When it comes to crawler dozers, bigger really is better. Bigger dozers are more efficient - they push more material per hour, and per shift, for a lower overall cost per yard. Presenting the most efficient of them all-the Komatsu D575A-3 Super Dozer. The largest, most productive dozer in the world by a factor of nearly two.

Komatsu-integrated design offers industry-leading productivity and reliability, now with additional advanced standard features. Hydraulics, power train, frame, and all other major components are engineered and manufactured by Komatsu. You get a machine whose components are designed to work together for higher production, greater reliablity, and improved operator comfort.

1,150 HP / 858 kW turbocharged, aftercooled engine provides plenty of power.
