FIELD: agriculture; machine building.
SUBSTANCE: invention relates to agricultural machine building, particularly, to a scraper for the opener assembly. Opener assembly includes a scraper with a top section of the front edge adjoining the central part of the disc colter and made to contact with the disc colter, when the disc colter essentially is not deviated, and a lower section of the front edge adjoining the outer section of the disc colter and made to contact with the disc colter, when the disc colter essentially is not deviated. Upper section of the front edge and the lower section of the front edge are configured able to maintain contact with the disc colter at deviation of the outer section of the disc colter relative to the central section of the disc colter along the arched trajectory.
EFFECT: such design solution is aimed at increasing efficiency of the scraper operation.
