Modern technologies for the cultivation of small-seed crops impose increased requirements on the sowing operation, the quality of which is largely determined by the design of the coulters used. The developed design of the coulter for sowing small-seed crops, which qualitatively prepares the planting furrow by leveling and compacting the surface of the bottom of the furrow. The stable distribution of small-seeded crops during their sowing significantly affects their productivity, since this forms the feeding area. Compliance with agricultural requirements for the uniform distribution of seed material is a priority task in the design of coulters and closing bodies of seeders. The use of skid coulters makes it possible to use their single-row installation, which, together with protection against damage when leveling and compacting the bottom of the planting furrow in one structural unit, makes it possible to reduce the metal content of the coulter and increase its compactness. When determining the parameters of the coulter, taking into account the condition of stability of its movement when sowing small-seed crops, a theoretical substantiation of its traction resistance was carried out.
