The article deals with the question of economic efficiency of moldboard tillage using the developed combined ploughshare plow as a result of experimental studies, determining the degree of traction resistance of the reversible plow tillage combined with reversible plow. We have also found main economic indicators of the manufacturing operation and calculation of efficiency of investments for the implementation of the combined plow

In the article, the question of the value and location of disk tillage tools in the system of machines and the most common crop rotation tillage technologies has been reviewed. We have also identified the problems of disk tillage tools using and the ways to solve them

The article is devoted to the scientific approach by means of automated projecting for modeling of processes of interaction of soil-processing tools with soil. The article has an applied character expressing that the method of automated projecting in Mathcad and with the help of the program SAP COMPAS 3D. There were presented the analyses of expressions as three-dimension graphics and was given their detailed analysis which can be used at implementation of construction of aggregates executing the main soil treatment with layer’s circulation. There was the main tendency of working outs of soil-processing machinery, improvement of arable aggregate constructions to make better their qualitative indexes of work. In the result of conducted work there was obtained the construction of combined mouldboard with additional flat-cutting working organs, was made up the matrix of planning of the experiment, was obtained the graph of dependence of the capture’s width of flat-cutting razor from the speed of movement of arable aggregate from which we can see that at increase of coefficient of capture’s width of flat-cutting razor the decrease of productivity happens, and the worsening of qualitative indexes of work of mouldboard respectively; there were substantiated the factors of influence the productivity; in the result of use of planning of two-factor experiment on orthogonal plan were determined the optimal parameters of work regimes of mouldboard

The article deals with the calculation of basic parameters of making bulk materials on the surface of the field. This calculation makes it possible to obtain data on the required amount of particulate matter

The article deals with the question of tillage with a turnover of reservoir devices for its implementation. We have also identified problems that exist in this process step. The ways of their solutions and their implementation have been proposed as well

The article discusses the importance of the application of centrifugal spreaders in the modern trends of development of this process step using precision farming. We have also identified the problems, using modern spreaders on farms and ways to solve these problems
