The broadcast cotton harvester header assembly unit includes two parallel frame members having a front and rear end. The rear end of the frame members have rotatably mounted thereon two drive sprockets. The front end of the frame members have mounted thereon two idler sprockets. The drive sprockets and idler sprockets have wrapped around them conveyor chains which rotate around the front and rear sprockets. The conveyor chains have attached to them, evenly spaced apart, two or more paddles, the paddles are attached to chain links by hinges.
