Abstract: A head assembly can be operationally mounted to the outlet of a conventional harvester extractor, such as a sugarcane harvester. The ancillary fan assemblies can generally direct suspended trash materials (that would otherwise be expelled from an extractor outlet) in a substantially upward and laterally outboard direction—that is, toward both lateral sides of a harvester. A duct assembly having an inlet and an outlet generally extends from each ancillary fan assembly to a position generally above a track of a harvester. Trash material expelled by a harvester extractor enters the head assembly and is directed by the ancillary fan assemblies into the duct assemblies, through the duct assemblies, and onto the upper surfaces of the tracks of the harvesters. The trash material is then conveyed by the tracks toward the front or forward portion of the harvester, where it falls off of the tracks generally in the path of the harvester.
