ABSTRACT A portable hydraulic actuated machine for driving posts, ground anchors, concrete breakers, core drills and the like work pieces into the ground, pavements, or wall structures, maintains a continuing thrust on the work piece amplified by sequential hammer blows of controlled magnitude to advance the work piece at a rapid rate without damage to the impact receiv- ing end of the work piece. The machine includes an automotive vehicle which is easily transported to the work site and which carries a turntable supporting an upstanding tower on which rides a carriage slidably mounting a spring loaded heavy hammer, a work piece engaging spring loaded anvil struck by the hammer and hydraulical hammer lifting mechanism. The tower is easily raised and lowered, adjusted toward and away from the vehicle and tiltable laterally to present the hammer and anvil to the work piece at the exact desired location in the plane of the work piece. The carriage is downwardly loaded to compress the anvil spring for exerting a continuing thrust on the work piece.
