Dozers are machines designed primarily for cutting and pushing the material over relatively short distance.

They consist of a tractor with a front mounted blade, controlled by hydraulic cylinders to vary the depth of cut and rate of leveling depending on the material and application.

A dozer is a front mounted unit with a blade curved in its section extending in the front of tractor.

Bulldozer is a most versatile and most important equipment on construction projects.

It is basically a pushing unit, but is widely used as a multipurpose equipment and can perform large number of operations with minor changes under different names like angle dozer, tilt dozer, tree dozer, push dozer.

Angle dozer is used to push its load at an angle of nearly 25 degrees to the direction of travel of dozer.

The tilt dozer is used where blade is required to be tilted by raising one end upto 25 cm above other so as to start excavating a ditch or a trench or excavation in hard ground.

The push dozer is used to push the scraper unit during digging or loading operation by means of a rectangular plate called pusher plate.

Tree dozer is used to remove trees.
