As early as 1955, a series of prototypes of a heavy wheeled bulldozer were built and tested, which at that time were still known as the MAZ-528. It is not clear exactly when the designation changed to MAZ-538, or why the change was made. However, it is known that the machines were manufactured from 1964 under the name MAZ-538 in series production.
The D575A-2 SD Super Dozer was the second version of the D575A, going into production alongside the D575A-2 SR Super Ripper beginning in 1995. [3] The D575A-2 SD Super Dozer is an 1,150 horsepower (860 kW), 143,300 kilograms (315,900 lb) dedicated dozer with no ripper. The D575A-2 SD Super Dozer was superseded by the D575A-3 SD Super Dozer.
The Caterpillar D11 can be distinguished from the Komatsu D475 by the elevated drive sprocket, or "High Drive" system, which results in a triangular, rather than oval, shaped track. The updated version of the Komatsu, the D575A, is the world's largest production bulldozer at 168 short tons (152 t) and 1,150 hp (860 kW). [5]
The cost of a new Cat D9 bulldozer is at least $900,000 (£739,624) but extensive “slat armour” editions and offensive capabilities mean the vehicle’s total cost likely exceeds £1 million.

The next year, Deere decided to design its own tractor, and Dain founder, Joseph Dain Sr., was directed to design that tractor.
