Abstract

A rotary combine and a method for threshing and separating crop are disclosed which utilize separate rotary threshing and separating assemblies. Both assemblies are in the form of cylinders and the separating assembly is located transversely and rearwardly of the threshing assembly. Crop is introduced along a plane substantially tangential to the lower entrance portion of the threshing assembly, conveyed by guide vanes to an end portion of the threshing assembly, passed from the threshing assembly axially into the separating assembly and conveyed by a series of further guide vanes to the rearward portion of the separating assembly where the crop residue exits from the combine.
