Abstract: The internal hydraulics of a three-point mount system of a tractor are utilized to drive stakes or posts. A base is rigidly mounted on the tractor chassis and rigidly braced to the stationary point of the three point. A frame having an upright member is rigidly mounted on the base and has a holding assembly with a latch or anvil for holding and urging a post or stake downwardly. The lever arms of the movable two points of the three point connect via pivot points, push levers, pivot points, pivot arms, and pivot points to the movable assembly such that upward movement of the two points effect levering of the assembly downward. The pivot arms are connected via centerized pivot points, and holding arms to the base.
