ABSTRACT:
A straw discharge assembly allows the beater to reach further towards the rotational axis of the threshing rotor, thus enabling it to remove a greater percentage of the straw which otherwise collects on the housing frame members. The beater has a barrel-shaped body, but it takes on an hourglass shape as it is divided into a center section with shorter blades and two side sections with longer blades, giving the center section a smaller effective diameter than the two side sections. The beater does not interfere with the rotational path of the rotor housing frame even though it is effectively closer to the housing frame. With their longer blades, the side sections are closer to the rotating frame legs and can therefore pull down and discharge more of the obstructed straw. The discharge grate is conformed to the effective shape of the rotor in a similar fashion.
