Abstract: A cotton cleaning attachment for a cotton scraper has a separator section mountable at a discharge end of a conventional scraper so as to receive scrap cotton, dirt and debris downwardly under the force of gravity from the discharge end of the scraper and separating the dirt and debris from the cotton. A transfer section, also mountable on the scraper and disposed downstream of the separator section, removes the cleaned cotton from the separator section, and causes the cotton to be fed to a subsequent stage of handling for further processing.
