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 article reveals the main empirical factors that increase the efficiency of technological systems of grain harvesting. The work 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 to develop a conceptual model (paradigm) research. The article reveals 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

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

In the article, we present: the analysis of grain combines, a perfect grain combine with new cutter bar of header and new rotation separator with a gentle principle of threshing, the experiments for definition of the optimal parameters of the new separator

In the article we have submitted physical fundamentals of processing machinery and equipment repair and recovery formulations; above all, the physical picture of the process of friction on the example of a pair of steel – iron is given

This article is a presentation of production tests and calculation of economics indexes for tillage with universal chisel plough

The analysis of the existing mechanical ways to determine the traction resistance of agricultural machines and development of new constructions of plants for engineering assessment of soil-cultivating working bodies has been presented in the article

The reliability of work of the technical systems significantly influences the technological losses of manufacture process. During the counting the availability ratio of the technical system it is recommended to take into the consideration implicit as well as evident breakdowns of all separate components of the whole object. There is a formula for counting technological losses depending on the availability ratio of technical object. Similar formulas for counting losses proceeding of atmosphere and water resources pollution, pollution of soils with hard matters are obtained. Introduced identities bring together reliability of the technical systems and separate components of ecological losses

Ensuring the food security of the country in the conditions of growing consumption of crop products and excluding dependence on foreign producers poses a serious question for science to increase the volume of production while maintaining soil fertility. One of the important tasks in solving this problem is to create a moisture-saving and moisture-accumulating soil layers. This article focuses on the cultivation of winter wheat. In addition to providing moisture in the cultivated layer, crop losses are observed as a result of the defeat of plants by Fusarium. Also, to ensure the co-storage of the fruit layer, it is necessary to reduce the use of chemical means of protection, less intensive impact on the treated surface by the running systems of power facilities and working bodies of machines, but with compliance with the primary requirements for the treated surface. To complete the tasks, we have developed a universal plow with a turning beam. Chisel working bodies are installed on the front of the beam. The formation turnover is performed by the disk working bodies installed further. The main element is a skating rink. The article presents the scheme of sets of plow on different types of work, as a universal combined machine and to perform individual types of work
