The device comprises a shear adapted to be mounted to the boom of a backhoe or like machinery with relatively movable members and be actuated by a powered, movable member of the backhoe. The shear comprises a generally U-shaped support member adapted to be disposed about the top of the backhoe boom. The shear also includes a pivotally mounted cutter head adapted to engage an anvil section attached to the support member to shear an item such as a metal member inserted therebetween. A cutter head is actuated by the backhoe movable member and is pivotally returned to a raised position after a shearing operation by a biasing means connected to the cutter head. The invention also includes a locking means to maintain the cutter head in a closed position when a shearing operation is not desired; a stripping member disposed adjacent the anvil section to assist in restraining items to be sheared during a shearing operation; and a guide member for preventing excessive deflection of the cutter head during a shearing operation.
