Abstract

Resilient attachments are mounted on a feed auger of the type having a central drum mounted for rotation about a longitudinal axis, spiral flights mounted on longitudinal ends of the drum, and a central drum portion having a plurality of radially extending feed fingers. Each resilient attachment is mounted on and extends radially from the central drum portion about one of the fingers. During operation of the auger, the attachment prevents the accumulation of vegetation on the auger, improves feeding of the vegetation to the combine throat and protects the auger from damage.
