Abstract
Cotton harvester multi-piece duct structure for conveying cotton materials between a cotton harvesting row unit, arranged toward a lower end of the duct structure, and an inlet opening of an extendable/retractable basket assembly. Toward an upper end thereof, the duct structure has a distal end operably connected to a remaining portion of the duct structure to allow the distal end of the duct structure to period between an operational position, wherein an outlet end of the duct structure is in general registry with the inlet opening to the basket assembly, and a storage position, wherein the distal end of the duct structure is lowered from the operational position to facilitate transportation of the cotton harvester. A lock mechanism is also disclosed for releasably fastening the distal end of the duct structure in an operational position relative to the remaining portion of the duct structure.
