The cultivation of melons and gourds is a rather laborious process and the main costs fall on the treatment of crops from weeds and harvesting. Before the weed damage threshold is reached, three or four row spacing treatments with cultivators are required, which ensures soil compaction. The number of treatments can be reduced by loosening the row spacing 0.1 to 0.12 m with a device capable of affecting the root system of weeds. It is established that weeding out is affected by the gear ratio between the weed extractor rotors. In order to determine the optimal value of the gear ratio on the technological process, the author conducted laboratory and field studies. The distance, on which the root diggers interact with the soil, was determined in the soil channel when varying the gear ratio from 1.0 to 4.0 and the depth of cultivation of 0.05 and 0.1 m. In field conditions, the author measured the length of weed roots removed from the soil at a working depth of 0.05 and 0.1 m, at the gear ratio of 1.0 to 4.5, and with a pitch of 0.5. As a result of research, the author observed the optimum length of traces of the front sections of the digger equaling 0.35 m and that of rear ones equaling 0.08 m at a gear ratio of 4.0. The greatest length of weed roots extracted to the surface with the digger blade of 0.26 to 0.32 m was observed at a gear ratio of 4.0 and a depth of 0.1 m. It is concluded that the efficiency of tillage depends on the gear ratio between front and rear rotors and the depth of tillage. The highest weeding-out efficiency was observed at a gear ratio between the weed extractor rotors of 4.0.

It was shown that the soil formation turnover within the furrow is an important condition for precision tillage. The authors identified the possibility of creating a train of combined machines capable of preparing the soil for sowing or planting in one pass. It was noted that due to inertia forces, the cylindrical plow body is able to hold a layer with and without turf. The preliminary tests of this working body revealed some barriers to the unhindered passage of the soil layer. It was assumed that it is possible to increase the technological reliability of the plow body by placing a wing on the guide board, which operation will create an additional twisting effect. (Research purpose) To substantiate the length of the plow body wing and its angle to the bottom of the furrow. (Materials and methods) Based on the laws of theoretical mechanics, a differential equation for the soil layer segment rotation was obtained, where the soil, as a tillage object, is presented by the coefficients of dynamic viscosity, sliding friction, and density. (Results and discussion) It was determined that the value of the dynamic viscosity coefficient and sliding friction depend on the absolute moisture content of the formation being treated. The main criteria influencing the soil formation turnover included the absolute soil moisture content, the plow body speed, the dump wing length, the angle of the wing installation, the thickness of the interacting boundary layer of the deformable section. As a result of the simulation, it was found out that the angle of the soil layer segment rotation predominantly depends on the plow body speed and the angle of the dump wing installation. (Conclusions) A 90-degree angle of the soil layer segment rotation can be achieved if the dump wing length is 0.1 meter, and the angle of its installation is 23 degrees.
