Science-based farming systems have proven that the soil layer after plowing contains 100-200 million to 2-3 billion weed seeds per hectare, 70-90% of which can be destroyed by harrowing before and after emergence. Pre-sowing cultivation with rotor trowels leads to the development of seeds in the soil and the creation of an aeration process for the root system during the growing season, which improves plant development and productivity. A flexible trowel with a rotor was developed in our laboratory. Constructive and technological parameters were analyzed using the experimental planning method and optimal results were obtained, considering the diameter of the rotor and the speed of the unit as the main influencing factors. The "percentage of lump crushing" was the output parameter, and the "soil moisture" was the input parameter. The regression equation and diagrams were obtained from the mathematical analysis. Optimally, based on 4 experiments, the unit speed V=15 km/h, the cultivation depth 5-10 cm, and the rotor diameter D=380 mm were selected. The technological operations carried out using a flexible trowel with a rotor made 81.28% of the lump crushing in the soil, which had a significant effect of 95% on the development of the sown seeds. In the field test, the degree of "lump crushing" was studied in the soil with a moisture content of 18-24%. It was found that the fraction of soil with a size of less than 10 mm amounted to 51%.The size of the lumps was 10-25, those of 25-50 and 50-100 mm made up 18%, 13% and 14% of the soil, respectively. The size of lumps above 100 mm made up 4% of the soil.
