Abstract
A backhoe is mounted on the rear end of a tractor and includes a boom constructed of first and second separate sections which are interconnected by means that are selectively alterable to establish first and second conditions respectively wherein the first and second separate sections are fixed relative to each other to thereby establish a rigid boom for normal backhoe operation and wherein the first and second sections are pivotable relative to each other to thereby establish a foldable boom to permit the latter to be moved toward the tractor to a folded transport position.
