ABSTRACT:
A cellular bulldozer blade is disclosed which is adapted to be carried by a plurality of support members. The blade includes a transversely extending moldboard having a front face for carrying earth or the like and a rear face, and a plurality of plates are secured to the rear face of the moldboard for cellular reinforcement thereof and to define a bracket receiving recess therein. A built-in bracket including a body portion having a forwardly facing surface and a rearwardly facing surface thereon is disposed in closing relation to the recess and is peripherally weldably secured to the plates. A bearing arrangement is secured to the rearwardly facing surface of the body portion of the bracket for load transferring connection to one of the support members of the blade, and an elongatably penetrating internal web extends forwardly from the forwardly facing surface of the body portion for vertically stiffening the bracket and the cellular construction of the plates.
