Abstract
The materials on evaluation and selection of machine-tractor units by the criteria of minimization of their production and operation costs (total specific energy intensity of MTU for its production and operation) and maximum productivity in carrying out the technological process of soil cultivation are presented. It has been established that the range of technological machines for carrying out the technological process "cultivation" with the power of mobile power plants up to 110 hp is determined by cultivators such as KPS-4, KBM-4.2 type using tractors JD5620, AGCO MF3640, UMZ-6, LTZ 95B, JD6020, MTZ-80/82, MTZ-920, Belarus 900, Belarus-921, Belarus-923, Deutz Agrofarm 430 and MTZ-1025. They have the total specific energy intensity of use with the designated technological machines at the minimum level, and the productivity at the maximum. In the power range of tractors from 110 to 145 hp it is advisable to use cultivators KSHU-5, KSHU-6, KPS-8P with mobile power tools New Holland T6050 Delta, CASE IH Maxxum 125, JD 6130D, JD 6135, MTZ-1221, Belarus 1220, LTZ-155 and MTZ-1222, which also have the maximum productivity at the minimum level of the total specific energy consumption for their production and operation. It has been found that when using cultivators of the type KSHU-12, KBM-7.2P, KBM-10.8P, Leader-6N, APC-7,2, RTS1831, KPO-7.2, KORUND 8/900 (power of the energy means up to 150-210 hp), according to the indicated efficiency criteria, it is advisable to use tractors T–150K, MTZ-1523, HTZ-121, HTA 200- 10, Belarus 1525, HTZ 17221, Terrion ATM 3180, Deutz Fahr Agrotron 165.7, JD 7030, ATM 4200 Terrion, MTZ-2022. It has been established that for the use of cultivators Leader-7.2N, Leader-8, according to the indicated criteria for minimizing energy consumption and maximum productivity, tractors with a power of up to 210-240 hp like JD 7830, JD 7930, New Holland 7060, Deutz Fahr Agrotron L720 DCR, Claas Axion 850 are required.
