Abstract
A duct support and transition structure for the air system of a cotton harvester includes a plurality of upright telescoping duct sections connected to a vertically adjustable support tube extending transversely between the sections providing lateral support for the ducts. Hydraulically operated slide structure connected to the support tube moves the sections vertically between operating and transport positions and eliminates duct binding problems. A telescoping harvester basket supports forwardly extending hood structure. The hood structure opens downwardly towards the upper ducts and includes grates for exhausting air and debris. The ends of the ducts open upwardly rather than rearwardly into the hood structure. The basket can move to and from the dump position without interference from the ducts, and the hood structure reduces cotton loss without need for side shields.
