a 1,150 horsepower (860 kW) tractor crawler produced in a ‘SR’ or Super Ripper bulldozer/ripper configuration, or as a dedicated bulldozer in the form of the ‘SD’ or Super Dozer.[1] Both models can move 90 cubic yards (69 m3) of material per pass using the standard blade. The D575A-3 SD Super Dozer can move 125 cubic yards (96 m3) of material per pass if equipped with an optional blade.[2][3] The D575A-3 can dig to a maximum depth of 6 feet 9 inches (2.06 m) using its single-shank ripper.[4]
Commonly referred to as the ‘world’s largest production bulldozer’, the D575A series bulldozers were produced by Komatsu Ltd. in Osaka, Japan.[4][5] Surface mine operators in the United States, Australia and Japan were the primary users of the D575A, although they were sometimes used in heavy construction applications and quarries as well.
