Abstract
The article presents the results of experimental studies on determining the effect of the vertical loading applied to a double-disc coulter of seed drill on uncultivated soil, i.e., the depth of the seeding furrow opened by the disc seeder coulter and its average square deviation, and the resistance to traction of the seed drill coulter. According to the results of the research, it was determined that the vertical load given to the double disk coulter should be at least 250 N in order for the seeder to plant repeated crops on uncultivated soil to work at the level of existing agrotechnical requirements.
