Using the technical characteristics of the PBS-10P trailed single-furrow plow and the results of tractor tests made by the Nebraska Tractor Test US laboratory, the value of towing tension of Case Magnum 340 (239 kW), New Holland Т9020 (213 kW), Challenger MT 835 (271 kW), John Deer 9120 (182 kW), Versatile 375 (226 kW), Versatile 400 (247 kW), New Holland Т9030 (310 kW) tractors and traction resistance of the PBS-10P plow at appropriate speeds were determined. The analytical dependencies of the traction force of the tractors and the traction resistance of the plow on the speed of movement are determined. The method of determining the rational composition of the arable unit is described, including: experimental determination of the plow traction at different tillage depth and speed; determination of the tractor force at the maximum traction power of the tractor; approximation of the obtained results in the form of empirical formulas; building graphical dependencies by empirical formulas and determining the optimal speed of the arable unit, which is used to calculate the productivity of the arable unit.
