ABSTRACT:
A grate for an agricultural combine includes curved grate segments, each of which include mounting holes in at least one end segment. To provide a threshing grate, the end segments of the grate segments are offset to provide a “step”, or discontinuity in the radius of the assembled grate, which improves the threshing efficiency of the combine. The step can be provided by offsetting mounting holes between adjacent grate segments, and securing the grates to a frame member.
