ABSTRACT:
A sheepsfoot assembly including a sheepsfoot frame section, an engine housing section with protective canopy, a vibratory sheepsfoot drum assembly mounted in the frame section, the drum assembly containing a rotatable drum with an internal bearing and eccentric shaft assembly and a plurality of spaced compacting teeth on the drum. The sheepsfoot drum is rotated when the machine is pushed or pulled over the soil by the prime mover to which the sheepsfoot assembly is attached. The drum is not powered for rotation, but only for vibration by the engine assembly.
The sheepsfoot frame includes a mounting jaw arrangement for securing the machine to the integral lip of certain prime movers, e.g., front end loader, or to an added lip as for attachment to dozer blades. In this manner, the prime mover can straddle a trench and the sheepsfoot assembly can be then lowered into the trench until it contacts a backfill layer for soil compaction.
