ABSTRACT:
An apparatus for driving posts into the ground, comprises a hammer for striking the top of the post to be driven, an articulated arm for connecting the hammer to a mobile power unit; and means for raising the articulated arm so that the hammer is above the post. The hammer is pivotally connected to the arm so that the hammer will strike the top of the post generally squarely when the power unit is level and when the power unit is not level.
