Analysis of research and development of pre-sowing machines and units shows that there are many trailed, semi-trailer combined units with different design and technical characteristics. In general, the significant disadvantages of these aggregates are the insufficient quality flatness of the microreliefs and the fragmentation of the soil. Compared to the basic complex with the use of a machine, the use of the proposed unit contributes to: a decrease in the density of the soil at the level of 0...20 cm by 15.6...17.1%, an increase in porosity by 34.7...37.9%, which will have agrotechnical significance. The content of the soil aggregate increased by 19.7...33.3%, the sawdust fraction decreased by 1.8...5.9 times. It was determined that the unit should move at a speed of 9...10 km/h.
The object of the study is the modeling of the selection of working bodies of the combined tillage unit. The principle of alternation of tools, which are carried out by the tillage machine used in performing the necessary operations, is the basis of the technology of combined tillage. The choice, alternation of methods of soil treatment and adjustment modes depends on the conditions and characteristics of the field. In order for soil tillage machines used for combined tillage to meet the criteria for their efficiency with predetermined quality to perform soil tillage operations, it is necessary to provide optimal modes of adjustment of working bodies.
In this regard, it is necessary to develop mounted combined tillage units, which are characterized by simple design and low cost and are able to perform many technically interconnected operations at the same time: high-quality leveling of the microrelief and grinding of the soil to remove plant residues, in a word, to ensure timely and high-quality preparation of the soil for sowing, while reducing energy consumption.
