Traction resistance study of the stuff seeder SKP-2.1

The article presents the results of a study of the traction resistance of a stubble grain planter-cultivator SKP-2.1 with mass-produced standard foot coulters and experimental combined coulters of the design of the Omsk ANC. Comparative studies were carried out on an aggregate consisting of the MTZ-82.1 tractor + the SKP-2.1 seeder according to the stubble agrophone from the previous crop – wheat. The speed of the unit: 7, 9, 11 km/h. Stroke depth of working bodies: 0.04, 0.06, 0.08 m. The study of the traction resistance of the seeder was carried out using the information-measuring system EMA-PM and the strain gauge link. It was found that the traction resistance of a drill with experimental combined coulters at a speed of 9 km/h and a sowing depth of 0.04 m is 33.3 % less than that of a drill with standard foot coulters; at the same speed and sowing depth of 0.06 m, the difference was 13.8 % in favor of a combined coulter. With an increase in the sowing depth to 0.08 m, the traction resistance of the combined coulter is only 3 % less.
