Abstract
A bulldozer assembly comprises a pair of laterally spaced push arms pivotally mounted at their forward ends to a blade. A stabilizing member is secured to each of the push arms and the members are disposed rearwardly of the blade in disconnected relationship therewith. The inboard ends of the stabilizing members are pivotally connected together by a transverse pivot pin disposed one-half the distance between the ends of the push arms. In a first embodiment, the pivot pin is confined within the stabilizing members whereas in a second embodiment the pivot pin extends completely through the stabilizing members and into the push arms.
