FIELD: agriculture; machine building.
SUBSTANCE: invention relates to agricultural machine building, in particular, to drill coulters of sowing drills for sowing of seeds of agricultural crops. Drill coulter for sowing of small-seeded crops includes a nosepiece to which cheeks are welded, an axis on which a scraper bar is hingedly fixed, and a receiving funnel connected to a seed pipe. Receiving funnel, which also functions as a seed distributor, has a curvilinear surface made as brachistochrone with guide grooves of curved shape in cross section.
