Due to the disconnectedness of production processes, prevention of soil degradation and plant diseases, as well as the difficult establishment of functional dependencies between the parameters of the working bodies and the physicomechanical properties of the soil, the richness of foreign technology, there is the problem of creating innovative structural and technological solutions for basic soil tillage including for the purpose of import substitution. To solve it, KubGAU has developed: “Multifunctional plow” (patent of the Russian Federation No. 2618342); “Plow with rotary bar” (utility model RF patent No. 184196); “Multifunctional plow with a rotary bruce” (positive decision on the patent application of the Russian Federation). Formal models, schemes and descriptions are given

The main indicators of efficiency of a cultivation machine are the following: productiveness and fuel consumption, which depend on complexity of work, operating depth and structure of the machine (type of the tractor and plough). The optimal structure of cultivation aggregate for the needs of each exact farm is complicated to do due to different determined and stochastic factors. In this case, Monte Carlo imitation modeling is proposed to use. As a result of models’ analysis, it is defined that all aggregates could be divided onto 4 groups of efficiency. Curves demonstrating dependence of fuel costs, compensation of losses caused by breakdown of agricultural terms and soil compaction caused by quantity of aggregates are built. After integration of the whole amount of aggregates into a common traditional technology of cultivation and after selection of its characteristics (quantity of aggregates, general fuel costs and losses costs, including fuel costs) it was proposed to split it onto 3 category modes: hard (according to technological mode – 2 or 5 shifts), normal (4-10 shifts), mild (6-15 shifts). The obtained models can be successfully applied in software of on-board computers in tractors and PCs of the engineers as well. Dynamical models for other technological processes in plant breeding could be obtained in the same way. All developed models allow us to make one more step towards precision farming and reduce costs for manufacture of end products

The considerable share in prime cost of products of agricultural production is made, now, by power expenses. It promotes that the considerable attention is given power - both resource-saving to the equipment and technologies. Thus, the modern science is faced by a global task – creation of cars and tools of new generation, high-economic, highly productive, less power-intensive and metal-consuming. One of the most power-intensive processes of production of agricultural production is processing of the soil. In this article on the basis of numerous researches use of rotary motion of the soil-cultivating working body allowing to improve a design of tillage machines, to reduce metal consumption, power consumption, to increase quality of work is offered. In this article, we offer the device for preseeding processing of the soil on a frame of which the working bodies in the form of flat disks with sharpening working in the horizontal plane, but with the accounting of an angle of deepening of working body are in chessboard order established. Rotary motion which promotes fuller cutting of rhizomes of weed plants and to improvement of quality of preseeding processing of the soil is forcibly transferred to working bodies. Justification of the offered device, constructive and technological schemes of the tool, conclusions and offers are given in the article
