Abstract
A single pivot and ledge structure located on the back wall of a lower duct of cotton harvester duct structure supports an upper telescoping duct section and facilitates free movement of the sections relative to each other, for example, when the row unit which is serviced by the duct is moved transversely or raised and lowered relative to the harvester frame. The pivot includes a bushing which extends rearwardly from an angle forming a ledge on the lower duct section. The upper duct section extends over the lower duct section and includes a U-shaped bracket which rests on the ledge. An aperture in the U-shaped bracket is received over the bushing to help position the duct sections and permit free pivoting of the upper duct section in both the fore-and-aft and the transverse directions.
