RESIDUE MANAGEMENT SYSTEM FOR A SEEDER ROW UNIT ASSEMBLY

A residue management system comprising a coulter disc rotationally mounted to a spring-tensioned swing arm that is pivotally mounted to the row unit assembly frame. The range of the swing arm is limited by default and forward stops contacting the swing arm's stop plate. An opener blade comprises a leading edge and a residue guide. When the row unit assembly is travelling, a tension spring mounted between the frame and the stop plate urges the stop plate against the default stop and the swing arm maintains the coulter disc in a default position at a default distance between the coulter disc and the leading edge; and as the coulter disc rotates, residue from a ground is carried by teeth of the coulter disc along the curved edge, from the leading edge of the opener to the residue guide, and then said residue falls away from the residue guide.
