ABSTRACT:
A hinged bulldozer blade with a central blade body and hinged outward ends coupled with a mechanism for selectively pivoting the hinged ends such that the blade can be arranged in any of several configurations. By selectively pivoting the sections independently of one another, the blade may be made to scoop and push material forwardly, remove material to either side of the blade structure, or remove material to both sides of the blade. A lockout mechanism is provided between the pivoted blade sections and the blade body that effectively transmits forces supplied to the blade sections directly to the blade body rather than through the attached jack assemblies by which the sections are pivoted. The blade body and end sections include complementary hinge surfaces that prevent formation of gaps between the hinged blade sections and the central blade body regardless of the pivoted position of the sections.
