Rational combining of a trailed plaster with foreign tractors
Using the technical characteristics of the PBS-10P trailed plow and plow and the results of the PBS series plow tests at the Povolzhskaya machine test station, the results of the tractor tests by the Nebraska Tractor Test USA laboratory established the hook force of the tractors John Deer 9120 (196kW), New Holland 9282 (175kW), Versatile 375 (268kW), Case Magnum 340 (251kW), Challenger MT 835 (267kW), Fendt 926 (200kW), Massey Fergusson 8480 (200kW) and traction resistance of the trailing plow PBS-10P at the corresponding speeds, hook force tra and the traction resistance of the plow from the speed of movement. The optimum operational parameters of the completed arable aggregates were determined by graphoanalytical method and their theoretical comparative estimation on productivity on the basic soil cultivation in different conditions is given. The results of experimental investigations of the Case Magnum 340 + PBS-10P arable aggregate in the conditions of the economy of the Saratov region are presented and the convergence of the theoretical and experimental studies obtained is checked.
