An improved double disk scraper assembly having a pivot post projecting rearwardly from the principal vertical support, a first scraper with a first pivot end on the post and a second scraper with a second pivot end on the first pivot end. The first and second pivot ends are preferably sleeved members. The scrapers are each engaged with a disk under the direct force of a biasing means, preferably a coil spring, between them. The pivot independently within a limited range which serves to keep the biasing means in place. A seed tube passes vertically between the scrapers for seed deposition at a forward position.
