An agricultural vehicle includes a chassis; a header carried by the chassis and configured to cut crop material; a chopper carried by the chassis downstream of the header; and a windrow assembly carried by the chassis downstream of the chopper. The windrow assembly includes a windrow chute defining a leading edge downstream from the chopper and a trailing edge downstream from the leading edge; and a roller associated with the leading edge to form an active leading edge of the windrow chute during rotation.
