A disk scraper system for an agricultural implement includes a tubular member slidably supported by the implement frame adjacent a gang assembly having a plurality of disks. Scrapers are fixed to the member and project into scraping relationship with the disks to remove dirt and debris from the surfaces of the disks. A hydraulic cylinder is connected between the frame and the tubular member and connected through a pressure control valve assembly to a source of fluid under pressure to bias the member so the scrapers are urged into scraping relationship relative to the disks. The pressure control valve assembly may be remotely adjustable to vary the scraper pressure on-the-go as conditions change. The system maintains the selected scraper bias even as the gang assembly moves vertically and from side to side relative to the frame with changing contour and soil conditions.
