The choice of the most optimal composition of aggregates for tillage for work in a certain economy is very difficult from many determined and casual factors. In connection with what, it is suggested to conduct researches with the use of quantificational and quantifier algebra logic. Also we need minimum influences on ecology, being characterized as a predicate of "minimum of expenses on indemnification of erosive losses of soil". For the agricultural technique of Russia, countries of the CIS and distant foreignness with the well-known norms of making (by the productivity) and expense of fuel imitation modeling is applied, on the method of Monte Carlo (Monte - Carlo Simulation), allowing to build a mathematical model for prognostication of necessary amount of aggregates at different normative agroterms with corresponding damages

The article reveals the main empirical factors that increase the efficiency of technological systems of grain harvesting. The article shows interrelation and subordination of empirical factors in the practice of operational reliability of grain harvesters, which underlies scientific research. We have defined the basic (key empirical factors) that allowed developing a conceptual model (paradigm) of the research. The article provides a technique establishing the rules of application of the method of expert assessments to identify organizational and technical factors that have the most significant impact on improving the reliability of grain harvesters

Experimental and theoretical researches of work of universal boardless plow tools with folding sweeps, helped to reveal defects, methods improvement of construction and tie powers resistance of soil and parameters of tools

The analysis of mechanized processes of bursting and experiment of definition of optimal parameters of tool of chisel plough with high degree of crumble of cultivate layer are presented

Analysis of mechanize processes of bursting and experiments for definition of optimal parameters of universal plow for chisel tillage of upper soil layer are presented

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

This is a presentation of new constructive-technological ideas for grain harvesting – grain stripper machine and construction for combing grain, as well as principles of their functioning

The article presents the analysis of mechanize processes for chemical protection of plants and the new construction of spraying with low gallonage, a new method and water solution and machine for address painting at litter plants by organic glue with chemical destroy, and new grass cutter with address painting of litter plants by organic glue with chemical destroy, and new cutter designed to destroy weeds with electric current

The article presents the analysis of mechanize processes of soil processing and new constructions of universal chisel loosening and combination sowing unit for seedbed soil structures loosening
