Abstract
The threshing drum comprising a drum body and beater bars. The beater bars each have a beating edge which describes a circumferential circle about a center axis of the drum body, on which the particular beating edge rotates about the center axis in a beating radius during operation of the threshing drum. To improve a flow of harvested material while the flow is being transferred from a threshing device to a downstream separating device, a cutting ring is positioned centrally on the drum body, viewed in the longitudinal direction of the drum body, which rotates in the circumferential direction of the drum body. The cutting ring has at least one circumferential cutting edge which describes a circumferential circle whose cutting radius, measured with respect to the center axis, is greater than the beating radii of the beating edges.
