Bulldozer (or dozer) blades are attached on the front of crawler tractors for the purpose of moving objects or soil. The blade height, tilt angle, and pitch are adjusted hydraulically, and they are supplied by the crawler tractor manufacturer. Dozer blades are also available for rubber-tired tractors as optional equipment from independent manufacturers.
Bulldozer blades are used to remove trees, clear land, construct roads, excavate ditches and ponds, dig contour trenches, and rake brush. The blades can be very a useful tool to shape sites before revegetation.
