Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
126 words
In a vehicle having a frame, an engine coolant radiator carried on said frame, and a bulldozer assembly pivotally carried on said frame, the improvement comprising: a radiator guard for protecting said radiator, said guard having corner portions adjacent the upper lateral corners of the radiator, each said corner portion defining a forwardly opening socket formed integrally therein, said radiator guard defining a rigid U-shaped assembly further including side portions and an upper cross portion, said corner portions being secured to the opposite ends of the cross portion and to the upper end of the side portions; and lift jack means having portions connected to said bulldozer assembly and mounting portions received in said sockets for adjustably mounting the lift jack means to said radiator guard.
Claim 2
Dependent Claim
