An apparatus for extracting a fastener, such as a nail, imbedded in a workpiece, such as a board. The apparatus includes an upright stand with a workpiece support table and a power ram actuated head mounted over the support table for forcing a projecting fastener end downwardly and dislocating a fastener head outwardly of the workpiece. A puller structure mounted below the support table is connected to a second power ram for swinging movement toward and away from the workpiece and the support table. The puller structure carries opposing grippers or jaw members extending upwardly toward the support table and connected to a third power ram for opening and closing the grippers or jaw members and seizing a fastener head therebetween. When the puller structure swings downwardly, the fastener is pulled from the workpiece.
