ABSTRACT OF THE DISCLOSURE Augering apparatus is intended for attachment as an accessory to a hydraulically operated boom of a backhoe or the like, the boom having articulated first and second members, the first member being pivotally attached to a tractor and the second member of the boom having a distal end hydraulically positionable in azimuth, elevation and reach from the tractor, and points of attachment for a scoop or the like. Such scoop is replaced by the accessory which includes a mounting bracket for being carried by transverse pins normally present at the end of the boom for mounting the scoop. The bracket carries a yoke in swiveling relationship for movement about a swivel axis lying in the plane of articulation of the boom members, the yoke having first and second oppositely disposed pivot members. A motor enclosure has pivot cooperative members, preferably trunnions extending from opposite sides thereof, for pivotally cooperating with the yoke. The enclosure contains a selectively reversible hydraulic motor. A coupling for receiving the shank of an auger is carried by a shaft driven by the motor and extends from one end of the en- closure. Hydraulic lines supply hydraulic fluid for operation of the motor, these lines preferably being connected at the trunnions. The trunnions provide a pivot axis which is offset from the swivel axis for castering action of the motor enclosure in respose to augering forces.
