"DISK BLADE SCRAPER" Abstract of the Invention The present invention provides a scraper mechanism for a disk blade including a wear ring attached to the rim of a rotary scraper and releasably biased toward and held in planar contact with one side of a disk blade. The wear ring is molded from a low friction, long-wearing material, such as molded nylon. The low friction material eliminates the metal to metal contact of conventional rotary scrapers and therefore eliminates the squeal associated with rotary scrapers. Also, wear of the scraper is audibly detected when the wear ring is worn away, thereby alerting the operator that maintenance is required.
