FIELD: agriculture; machine building.
SUBSTANCE: invention relates to agricultural engineering, particularly for seeders for sowing crops. Ploughshare comprises strap-connected sections, a furrow former with a hub with a bearing at centre, a seed tube, a scraper. Furrow former is made in form of a wheel, plate-like rim of which is wider than length of sown seeds, and hub thickness less than width of plate-like rim. Seed drill tube is arranged ahead of plate-type wheel rim. Lower part of seed drill tube is directed to side opposite direction of motion, and has a curved tip, radius of curvature which is equal to 20 mm.
EFFECT: such design will increase density of contact with soil seeds and to reduce soil layer above sown seeds compared to with depth of seed drill.
