Abstract
A system for detecting a blockage in the cotton conveying system for a harvesting unit on a cotton harvester. An upright flexible flap assembly is connected to a post or wall adjacent an upright doffing mechanism of the harvesting unit. A normally-open switch member is slightly offset from the flap. If a blockage occurs in the duct or discharge structure, cotton will begin building up near the doffing mechanism and will be pushed against the flap. The flap in turn contacts the switch member, which closes a circuit and provides a warning to the operator so the harvester can be stopped before the blockage causes serious damage to the harvesting unit.
