Baldwin was a brand of Australian articulated tractor. These included some with over 600 hp, which were thought to be Australia's biggest tractors, but none were as big as the Big Bud 747 from North America. The biggest are now seen as collectable.
E.M. Baldwin founded his company in 1928 as a general engineering firm. His son Frank led the company into building Baldwin's first tractor in 1979. The company's name was later changed to Baldwin Engineering. It was based in Castle Hill, NSW, Australia, and continued to build 4WDarticulated tractors until the 1990s. They also produced mining and industrial equipment.
