The analysis of soil processing technologies for sowing melons was carried out. When performing technological operations for sowing melons, it is necessary to perform basic and pre-sowing treatment of soil, as well as open irrigation furrows. Carrying out such operations is associated with high energy costs and multiple passes of units across the field. It is proposed to carry out strip processing of the soil for sowing melons. For its implementation, the design of a combined tillage system is proposed, which performs plowing, pre-sowing treatment and formation of irrigation furrows in one pass. When performing basic soil treatment, the plow working bodies of the front plow are used for smooth plowing, which ensures the turnover of the soil layer in its own furrow. The plow bodies of a two-body plow are installed along the axis of symmetry of the gun according to the Lister scheme. At the same time, not a complete turnover of soil layers is provided. They are simultaneously stacked in such a way that when the gun passes at their junction, an irrigation furrow is formed. Behind the plow cases, a ripping and levelling device is installed for strip pre-sowing treatment of the soil in the sowing zone. As such a working body, rotary working bodies with spherical knife elements are used, behind which a slatted roller is located. Using a combined tillage unit can reduce labour costs by up to 25 %, energy consumption for the process of preparing the soil by up to 50 %, and reduce the time of work, soil compaction and preserve moisture in the soil layer.
