A mobile vehicle is provided with a multiple purpose material handling and working apparatus including a boom, and a tool supporting boom extension supported on the free distal end of the boom for rotation about an axis parallel to the longitudinal axis of the boom. The boom extension includes a body, a linkage structure movable between unpivoted and pivoted positions relative to the body, a coupling, and a linkage drive assembly mounted on and movable with the body for driving the linkage structure between unpivoted and pivoted positions. A rotary drive motor is supported on the boom for rotating the boom extension relative to the boom.
