This invention pertains to a combine of the axial flow type in which rotor means extend longitudinally within the combine in association with concaves, the rotor having in axial alignment, a threshing portion and a separating portion rearward thereof and mounted for coaction with respective concaves disposed beneath the rotor. Tailings which are discharged from the separator section of the rotor and concave normally contain a worthwhile amount of crop material intermixed with waste chaff, straw and the like, and further threshing to separate the crop material from the waste material is effected by a rotatable beater and coacting grate which extend transversely to the axis of the rotor and rearward of the discharge end of the separator portion of the rotor and concave. To adapt the use of the combine to a wide range of different crop materials, the grate for the beater is adjustably supported for movement toward and from the beater by slidable wedge members respectively engageable with opposite ends of the grate, the adjustment being effected externally of the housing of the combine.
