Abstract
A system and method are provided for driving a ground anchor and associated anchor rod into the ground. The ground anchor is held securely relative to a drive gad which is reciprocated bi-directionally with an actuator. One end of the anchor rod is pivotally connected to the ground anchor. Another end of the anchor rod is connected either to the drive gad or to the actuator so that the anchor rod is caused to vibrate positively in phase with the anchor. The vibrating anchor liquefies the ground and can be pushed easily through the ground to a desired anchoring position.
