摘要：
FIELD: machine building.SUBSTANCE: furrow plow coulter includes a vertically disposed blade knife mounted on a bracket and allowing the soil and weeds cutting in the vertical plane to the seeding depth. Behind the disk a nosepiece with an acute angle of entry into the soil is fastened on the post with bolts, made in the form of a dihedral wedge, and behind the same post a seed pipe is installed to feed seeds of crops to the seed bed. Seeds are sown with a belt width of 70–80 mm. To both sides of the nosepiece sidewalls are attached, and the upper generatrix of these sidewalls is deviated from the horizontal line by an angle of α, and the bottom generatrix of the sidewalls is at an angle of α, wherein α<α, forming a trapezoidal sowing tool with the sidewalls deviation from the vertical axis by an angle of β. To obtain a densified seed bed, the sidewalls in the nosepiece lower part are connected with a horizontal plate by 2/3 of their length. Formation of the sowing furrow and compaction at the location
