Abstract

Abstract A tractor comprises a main frame, an oscillating beam support subassembly mounted on the main frame, an oscillating beam mounted on the beam support for limited pivotal movement about the longitudinal axis of the tractor, and laterally spaced crawler units connected to the ends of the oscillating beam. The subassembly comprises a pair of longitudinally spaced apart vertically depending cross members, each having a mounting flange thereon. The oscillating beam is provided with a hole near the center thereof for receiving a pivot pin which is non-rotatably press-fitted therein. The ends of the pivot pin extend outwardly of the hole and are supported for pivotal movement in holes extending through bearing blocks which, in turn, are releasably bolted to the mounting flanges. Clearance between the ends of the pivot pin and the cross members is such as to prevent axial endwise shifting of the pivot pin if any such tendency should develop.
