Abstract: A harvester suitable for triple windrowing operations has a cross-conveyor located behind the harvesting header for intercepting a stream of severed materials projected rearwardly from the header as the machine moves through the field. The cross-conveyor may be maintained in a raised or lowered position independently of the header so that, when the cross-conveyor is raised, the stream of severed materials from the header can be projected straight back underneath the raised conveyor to fall onto the ground generally in line with the header. For triple windrowing, a first pass is made with the cross-conveyor raised so that the first deposit is made directly behind the header on the mowed strip of the first pass.
