A knife blade cover for converting the rotary chopper element of an integral chopper assembly of a combine harvester to operate as a beater instead of as a chopping construction, which knife blade cover includes a cover member mountable over one or more mounted assemblies of the rotary chopper element of an integral chopper assembly of a combine harvester, which mounted assemblies include a mounting lug and one or more blades fixedly attached thereto, to envelop such mounted assemblies within the cover member while presenting to the residue flowing through the integral chopper assembly a relatively broad and blunt surface that acts to beat, instead of chopping, such residue, and connection hardware for mounting the cover member to the rotary chopper element. A plurality of knife blade covers may be provided with connection hardware as a kit for converting the rotary chopper element to operate as a beater construction.
