Biggest Bulldozers: Unlimited Horsepower Is Here

[@IL1007]

The Komatsu 575 is the biggest, but the D11 Cat just seems more iconic with the high drive design.

There are many BIG and NUMEROUS reasons why Cat is #1 worldwide. For me Komatsu and CAT are both great Dozers. 475A is the biggest but with the highest maintenance cost.
