Abstract
A power-operated implement mechanism mounted on the tip of a boom. The mechanism includes a torque tube which is rotated under power to rotate an implement mounting. A fluid-operated ram which is actuated to cause opening and closing of work implements in the mechanism has its rod extending downwardly through the torque tube then to be connected through linkage to the work implements. The work implements are pivotally mounted on the implement mounting. The implement mounting is rotated about the axis of the torque tube through power-operated means operatively connected to the torque tube.
