Abstract: The invention comprises an adjustable scraper device for scraping the disc blades of a grain drill. The device has a fixed mounting on the mounting for supporting the disc blades and a slidable mounting slidable along the fixed mounting to a selected adjusted position relative to the disc blade support mounting and the disc blades. Scrapers are mounted to the slidable mounting between the disc blades to be slid with the slidable mounting toward the center axis of the disc blades so that as the disc blade outer circumferential edge wears down, the scrapers, which act to scrape the disc blades, may be adjusted toward the center axis of the disc blades to keep the entire scraping portion of the scrapers within the confines of the outer circumferential edge of the disc blades, so that the scraping portion of the scraper will not wear on the outer edge of the disc blades and cause damage to the scraping portion of the scraper.
