Biggest Dozer.
Hi, Dozer Hand.
Welcome to the forum. That 'Kummagutsa' dozer may well be the largest dozer in the world - - - - currently in production. That would be the 'Kummagutsa' D575. However, the Acco dozer, at 183 tons, is almost 20% heavier and, at 1,350 horsepower, is almost 20% more powerful as well.
The Western 2000 mentioned above is also both heavier, at 170 tons, and more powerful, at 1,600 horsepower, than the D575. The Western 2000 was also a diesel-electric drive.
Both the Acco dozer and the Western 2000 were one-offs, not production run machines, so the big 'Kummagutsa' wins as the biggest production run dozer.
