ABSTRACT:
An attachment for use on an articulated boom of a back hoe has an elongated frame (A) for attachment on the boom opposite the bucket carrying an arm (B) having an elongated member receiving and positioning an elongated implement (C) opposite the open side of the bucket during a complete sequence of operation of the boom and bucket. A (D) removably secures the elongated implement on the implement receiving and positioning member for serving as a backup for the bucket gripping an object between the bucket and the implement. Thus an implement may be removably positioned in relation to the bucket of a back hoe for gripping an object therebetween for movement by the boom and for changing one implement for another upon the implement receiving and positioning members. An offset member (E) extends upwardly from the base for aiding in retracting the arm and the implement carried thereby. The telescoping members (F) provide a rigid support for the arm when in use as well as collapsibility to aid in retracting the implement for converting the back hoe from load moving to excavating.
