The D575A-3SD has a ground contact area of 101.55 square feet (9.434 m 2) and exerts an average ground pressure of 23 pounds per square inch (160 kPa). The Semi-U has a capacity of 44.5圓 (34m3) while the U-dozer blade has a capacity of 58.8yd3 (45m3). Either could be ordered with single or dual tilt cylinders. The D575A-3 could be optioned with a Semi-U blade or a U-dozer blade.

The D575A-3SD features a Super Dozer blade designed to dump, dig or carry that measures 11 feet 11 inches (3.63 m) high and 24 feet 3 inches (7.39 m) wide. Serial numbers 1003 were not produced due to the bad luck associated with both numbers (#4 and #13) in Japanese culture.Ī 12- cylinder, four-stroke, water-cooled, direct injected, turbocharged, intercooled, 1,150 horsepower (860 kW) Komatsu SA12V170E diesel engine powers the D575A-3. Serial Numbers 10101 – 10112 were A3 machines. Serial numbers ceased at 10043 and started back up at 10101 when the A3 series machine production begun. Serial Numbers 10001 – 10043 were A2 machines. Each machine had its model number and serial number stamped onto a personal identification plate that was located inside the cab. Following that, the series is represented (-2 or -3) and finally the configuration (SR or SD). In 2012, a custom order was placed by Alcoa in Australia and a final machine was built taking the total A3 build number to 12.Īll Komatsu bulldozers are identified by the letter D (for Dozer) followed by the model number (575A). These models were produced between the years of 20 and 11 machines were built. Upgrades made within the cab also included a new suspension seat and upgraded displays and monitoring systems. Upgrades included features such as the 'Palm Command Control System', smooth and soft operation modes, ECMV controlled transmission, ECMV controlled transmission steering clutches/brakes, preset travel speed selection function and auto-shift down function. They wore a new trade dress however most of the upgrades were electronic.

These were produced in both SR 'Super Ripper and SD 'Super Dozer' configurations. In 2001 the D575A-3 machines were introduced. These models were produced between the years of 19 and 41 machines were built. The first series of D575A bulldozers were the D575A-2 machines. The updated models, the D575A-3 and D575A-3SD Super Dozer were introduced in 2001.

The first D575A-2 SD Super Dozer was purchased and placed into service by the Princess Beverly Coal Co. The D575A-2 SR Super Ripper was joined by the D575A-2 SD Super Dozer in 1995. The first machine was built up by Anderson Equipment Company and then sold to American Asphalt and Paving Company where it initially worked in Las Vegas. The first production machine, delivered in 1992, was initially trialed in PA where the prototypes tested. Prototype machines are also believed to have been tested at the Harrison Coal and Reclamation Park. A successor to the D555A prototype, the D575A-2 SR Super Ripper, began field testing in North America in 1989 by the Cooney Brothers Coal Company in PA where over 1000 hours were logged. Due to economic conditions at the time, development was stalled for much of the 1980s. Komatsu first showed a 1,000 horsepower (750 kW) bulldozer prototype, the D555A, to the public at the Conexpo equipment exhibition in Houston, Texas in 1981. 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. Ĭommonly referred to as the 'world's largest production bulldozer', the D575A series bulldozers were produced by Komatsu Ltd. The D575A-3 can dig to a maximum depth of 6 feet 9 inches (2.06 m) using its single-shank ripper. The D575A-3 SD Super Dozer can move 125 cubic yards (96 m 3) of material per pass if equipped with an optional blade. Both models can move 90 cubic yards (69 m 3) of material per pass using the standard blade. The Komatsu D575A is 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.
