There are two types of bulldozers, if we consider the method of installing the dump. The first type of machines have a dump that is a non -rotten. The second type implies a machine that has a rotary dump and can establish various provisions for it, which makes it possible to do the work better. Work on such a machine gives more opportunities for the operator. In order to increase the productivity of the machine on light soils, the dump is supplied with special lateral openings.
