A fixed king pin extends between the side members and a breaker arm is rotatably mounted on the king pin. A hydraulic cylinder is pivotally mounted on the base, and the rod extending from the cylinder is pivotally connected to the rear end of the breaker arm so that extension of the rod from the cylinder pivots the breaker arm about the king pin to rotate the forward end of the breaker arm downwardly to contact a metal piece lying on the upper forward corners of the side members.
