ABSTRACT:
A vibratory sheepsfoot is attached to a coupling assembly that is mounted on a hydraulically operated tool bar on the back of a tractor. The coupling assembly is designed to permit adjustability of the vibratory sheepsfoot in a vertical direction. The coupling assembly is mounted on the tool bar such that it can be moved along the length of the tool bar to a desired position. The apparatus is especially useful in compacting earth in a trench offset to the side of the tractor.
