TECHNICAL AND ECONOMIC INDICES OF DOMESTIC AND IMPORTED DISC HARROWS
Description
The creation of better conditions for the cultivation of plants is carried out by means of mechanical impact on the soil working bodies of machines and tools, that is, the so-called tillage. Its importance in the conditions of intensive agriculture cannot be overemphasized. The use of each scientifically based crop rotation system of soil tillage is a necessary condition for further growth of crop yields and improve soil fertility. Tillage determines the processes of reproduction, fertility regulation soil modes, degradation processes and soil conservation. Important and how self-administration in the system of minimum tillage, and in addition to the deeper treatment of soil under traditional agricultural technologies is superficial and shallow tillage. Disc harrows are the most applied machine for the implementation of surface and shallow soil treatment, performing a loosening of topsoil, leveling the field surface, the destruction of soil crust, crumbling lumps of soil, weeding, seeding and fertilizer. This article describes the design features of domestic and foreign disc harrows. We have given their technical characteristics, and consider the operational and technological parameters

ENERGY PERFORMANCE OF MACHINES FOR SOIL CULTIVATION
Description
Currently a significant proportion of the cost of agricultural production is energy costs. Therefore, considerable attention is paid to energy and resource saving equipment and technology. In this regard, the role and importance of the energy assessment of machines, allowing determining not only the power characteristics of the power, but fuel consumption per unit of cultivated area or per unit of output. Conducting energy assessment of machines and equipment reduces the economic and labor costs, at the expense of more detailed and optimal selection of machines and units for performing certain manufacturing operations in agricultural production. In the article we describe energy evaluation of different tillage agricultural machinery aimed at determining energy consumption when executing the set of technological operations machines and equipment on the operation modes set by the standards under which stable the operations are performed. The use of the results of energy assessments on traction characteristics of agricultural machines and tractors will allow getting the maximum effect when performing technological operations. In turn, the lack of monitoring of key energy performance of cars during their operation leads to a partial use, which increases costs
