The D475 Dozer is a very large bulldozer manufactured by Komatsu. As of season 5, it is the largest dozer featured on the show.

This dozer has 900hp, weighs 100+t, with a 20ft-wide blade that does a 45-yd push. It is about 3x more powerful than the D9 Dozer.

The Hoffman Crew borrow a Komatsu D475A dozer, the "superdozer" for a day, in season 5, to use at the McKinnon Creek Claim, to strip the swamp cut. The superdozer is the largest dozer in the Klondike.
