(under the class definition) Apparatus comprising means movable relative to an earth working element or other part of the apparatus for cleaning said earth working element or said other part of the apparatus.
(1) Note. An earth working element having means to reduce friction (e.g., moldboard with rollers) is excluded. However, a nonearth working part (e.g., standard) having a relatively movable part such as a roller to prevent weeds, trash, or the like from collecting thereon is included under this definition.
