Abstract
A scraper for a coulter assembly is provided. One coulter assembly includes a scraper having an upper leading edge section positioned adjacent to a central portion of a disc blade and configured to contact the disc blade while the disc blade is substantially undeflected, and a lower leading edge section positioned adjacent to an outer portion of the disc blade and configured to contact the disc blade while the disc blade is substantially undeflected. The upper leading edge section and the lower leading edge section are configured to maintain contact with the disc blade as the outer portion of the disc blade is deflected relative to the central portion of the disc blade along a substantially arcuate path.
