Abstract
A convertible forage-handling machine which is capable of operating in tedding or windrowing position includes a plurality of bipartite arms mounted on a carrier of a raking wheel for rotation therewith. The two parts of each of the arms are always maintained in the same common plane regardless of the mode in which the machine operates, and are in permanent contact with one another via a motion-transmitting arrangement consisting of cooperating male and female connecting elements. One of the parts is swivelled by the cooperation of a cam follower rigid therewith with a stationary cam track, and the other part, which carries a plurality of forage-engaging tools at its free end, is caused by the motion-transmitting arrangement to share in the swivelling motion only when the machine operates in the windrowing position. The other part is pivotable between an extended position corresponding to the tedding position with the forage-engaging tools at a greater diameter and a retracted position corresponding to the windrowing position with the tools at a smaller diameter. The motion-transmitting elements include a projection of the male element received in a recess of the female element, at a distance from the axis of the other part in the retracted position, and coincidingly with such axis in the extended position.
