ABSTRACT:
A wheeled vehicle is provided including a plurality of plan area peripheral portions. A generally horizontal support beam is pivotally supported from the vehicle with one end of the beam projecting outwardly of one peripheral portion of the vehicle and vertical oscillation of the one end of the beam relative to the vehicle. A first motor is connected between the beam and the vehicle for effecting selected angular displacement of the beam relative to the vehicle and an upstanding support structure is pivotally supported at its upper end from the one end of the beam for angular displacement relative to the beam about a horizontal axis extending transversely of the beam. A downwardly opening clam-type digging head is carried by the lower end of the support structure and a second motor is connected between the beam and the support structure for angularly displacing the support structure relative to the beam.
