ABSTRACT:
An apparatus for facilitating penetration of a ground engaging member, such as a plowshare or fence post, into the ground is disclosed which employs a vibrator having a rotatable mass eccentrically mounted to provide a cyclical motion to the member being caused to penetrate the ground. The apparatus is adapted to independently vary the amplitude and frequency of the cyclical motion imparted to the ground engaging member to adjust for varying soil conditions. One embodiment employs a pair of interconnected balanced vibrators which produce a resultant force acting generally along the longitudinal axis of the ground engaging member.
