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. Key words: seed drill for planting repeated crops on uncultivated soil, vertical loading applied to a double-disc coulter, the depth of the open furrow and its root mean square deviation, coulter traction resistance, aggregate movement speed. 1 Corresponding author: [email protected]
