Abstract
An improved portable, ground stabilized, drop hammer assembly for impacting a ground surface and adapted to be removably coupled to a driven host transport apparatus is composed of a drop weight, a frame including a sidewall, bottom plate and a host transport apparatus engagement assembly, and a power assembly for vertically reciprocatingly moving the drop weight to impact the ground surface. A shock absorbing element is carried either the frame assembly close to the ground surface or by the drop weight at its end close to the ground. Such shock absorbing material absorbs any movement by the drop weight into the frame assembly close to the ground surface to prevent damage to the frame assembly.
