Abstract: A compost turning apparatus mountable on a loader for turning composting materials may include a mobile base having a frame with inboard, outboard, and bridging portions defining a windrow tunnel through which a windrow of composting materials are passed. The inboard portion may be configured to mount on the loader. The apparatus may include a rotor extending across the windrow tunnel, and the rotor may include a rotor shaft and paddles on the rotor shaft. A rotor drive assembly on the mobile base may rotate the rotor using a motor hydraulically-connectable to a hydraulic power system of the loader.

Abstract: A compost turning apparatus may include a towable mobile base being elongated in a longitudinal direction and having a lateral direction. The mobile base may comprise a frame, a tongue mounted on the frame, one or more transport wheels mountable in a transport setup and an operational setup, one or more support wheels mounted on the frame, and a drive wheel mounted on the frame. The apparatus may also include a rotor mounted on the mobile base to rotate about an axis oriented substantially parallel to the longitudinal direction of the mobile base. The rotor may have a plurality of paddles arranged in circumferential rows, with various paddle positions and paddle orientations.
