The article presents the new direction for union technical characteristics with productivity, and formal models for every method of production of grain and spike cultures and for general technology

This article is a presentation of a complex estimation of machines for chisel with application of desirability function

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

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
