Bulldozer

The bulldozer is a very powerful crawler that is equipped with a blade.  The term bulldozer is often used to mean any type of heavy machinery, although the term actually refers to a tractor that is fitted with a dozer blade.

Often times, bulldozers are large and extremely powerful tracked vehicles.  The tracks give them amazing ground mobility and hold through very rough terrain.  Wide tracks on the other hand, help to distribute the weight of the dozer over large areas, therefore preventing it from sinking into sandy or muddy ground.
