ABSTRACT:
A device for removing a post from the ground. The device includes two rigid plate members for engaging opposed sides of the post. Two fasteners extend through one of the plate members for threadably engaging the other plate members so that the two plate members can tightly engage the post. When a device capable of exerting a lifting force engages at least one of the plate members, and is operated to exert such a force against the plate member, the post is removed from the ground.
