An important direction in the greening of tillage is to preserve and improve the physical properties of soils in the optimal range of values, which is a necessary condition for the effective use of other agronomic measures that affect the formation of crop yields. With the advent of new, modern energy-efficient tillage tools, there is a need to conduct research on their effectiveness on the first stubble cultivation on the southern chernozem. The purpose of the research was to establish the influence of surface (stubble) cultivation with tillage tools of the “Lozovsky mashiny” brand after harvesting winter barley on the agrophysical properties of Southern heavy loamy low-humus chernozem in the conditions of the Southern steppe of Ukraine. In the research process, methods were used: field, laboratory, comparative-calculation, statistical. It was found that DUCAT-2,5 (short Harrow-Husker) best structured the soil among the studied aggregates. The lowest soil hardness values (0.48-1.33 MPA) and the tendency to form a plow sole were obtained in the version with vertical processing – Verti-till (turbo disk). The obtained scientific results of the research will contribute to the wider introduction into the production of new units of the “Lozivski mashini” brand for surface soil cultivation, which will contribute to the reduction of mechanical stress and the preservation of moisture in the soil
