The problem of a comparative evaluation of a new technique design under developing the engineering solution and documentation is set. The created fifth-generation mobile power unit (MPU) is compared to the modern machine-process units based on a modern tractor identical in a draught class. The problem is solved through a numerically-analytical method with the parameter synthesis of the multipurpose machine-process units. The problem solution is reduced to detailed calculations in both variants. A nine-field grain zonal rotation rich in green sowing is considered. The analysis has shown that the created MPU with a variable-speed tram drive, two hinged systems unified in load-carrying capacity, and two power-takeoff shafts, will provide unit cost reduction actually caused by the design at a minimum 500 Rub./ha. MPU specifications are as follows: 50 kN class, 220 kW capacity, 9000…9500 kg weight. The essential novelty that distinguishes a new MPU from the standard tractors is provided through the usage of complex multipurpose operations.
