Extreme buldozers

The Komatsu D575A-2 is the largest, most productive dozer in the world, by a factor of nearly two.

With a price tag of $380,000 US, the 575A has an operating weight of 142,800 kg (314,200 lbs),
and a blade capacity of 69 cubic metres (90 cubic yards).

It uses a massive 1,150 hp engine operating at 1800 rpm, and is favoured by the mining industry because it is very effective working in hard rock,
especially over long push distances.
