The article “Investigation of moving flat hexagonal disk attachment” reviewed the operation of flat hexagonal disk attachment used on discer for tilling the soil, exposed to wind erosion. The research of flat disk attachment is carried out in FSBEI HE OSAU named by P.A. Stolypin. The main laws are set and described and the quality evaluation criteria of cutting up weed vegetation δ in dependence upon angle of attack, cultivation depth and the distance between discs on the shaft are also represented. Using received dependences in practice it is not difficult to define the quality of weed vegetation cutting up and when required to make regulations of disc implement for quality weed vegetation cutting up. Arrangement is done by setting of basic parameters of stubble cleaner: angle of attack, cultivation depth and the distance between discs on the axle.

Abstract. Soil condition influences on its water conductivity, defining the completeness usage of atmospheric precipitations. Water conductivity relatively may be divided into summer and winter. Summer water conductivity depends much upon ground density but winter water conductivity solves more demanding challenge -accumulation of all winter precipitations in short time and depends not so much upon the density as its moisture [1].It is obvious, that ground moisture and the depth of its freezing define of snowmelt runoff and reflect the ability of the frozen ground to pass through itself moisture. However, more passing over the moisture is carried out by the soil with less moisture of topsoil and the depth of its freezing before spring period. Thus, carried out investigations allow to understand thoroughly the nature of spring flow of melt water and the character of washing away the soil from the slope. During crop cultivation in the steppe zone some parts of the soil rotation (up to 30%) is occupied by fallow fields, without vegetation for much time. These soils are more subjected to water and wind erosion. In this case the only possible methods of conservation them from destruction are special regional agrotechnical methods and means of tillage mechanization. Formation of planting holes on the field surface made by digging and embossing (pressing) will be more acceptable method of soil conservation from erosion under complex topography when the same field has versatile exposure and different steepness slope up to 4°. There are few articles devoted to the problem of antierosive treatment. But high agrotechnical effectiveness of holing by embossing (pressing) method on the steep slope up to 4° [2] has been established in these works. Decreasing water holding capacity of the holes influenced by form and the size of the holes as well as their position relatively slope is taken place by increasing the slope steepness. In order to exclude the influence of these factors on the hole capacity it is recommended to form them of bowl form with small capacity and in order to accumulate all snowmelt runoff on the unit area it is recommended to regulate the amount of holes, defined the total water holding capacity of this area. The aim of the investigation is prevention of water erosion on the fallow fields with the slope up to 4° according to the sizes and forms substantiation of embossed holes, defined hydrometrical criteria of melt water flowing.

in modern conditions, when the equipment of domestic industrial enterprises is significantly worn out, it becomes important to use outsourcing repairs as a way to improve the reliability of equipment by ensuring the quality of repair. The decision to outsource is made on the basis of different criteria using different approaches, some of which have certain drawbacks. For example, a decision based on a revenue change might be wrong because it is not related to outsourcing. Multi-criteria approaches are ineffective due to mutual compensation of deteriorating and improving criteria. The algorithm of decision-making on outsourcing of repair of the equipment and the choice of service providers on the basis of comparison of costs of outsourcing and insourcing is presented.The widespread structure of repair service of the industrial enterprises is considered and its reorganization in the conditions of repair outsourcing application is offered. The criteria and method of their calculation for the possibility of evaluating the effectiveness of repair outsourcing equipment. To assess the effectiveness of the reorganization of the repair service, the ratio of repair time, the number of failures, the number of defects, the repair costs are taken. For the detection of improvement or deterioration in the quality of the repair after the use of outsourcing, you must use the product of these relations.

The paper presents the results of analytical studies. It describes the basics of modeling the chisel plough and soil interaction; it further analyzes the hypothesis of how soil is deformed. To reduce the draught of the implement, the authors propose using elastic cutter mounts to induce self-oscillations. The paper derives the amplitude of such oscillations expressed in terms of the cutter tilt angle α(t) and the moment of all forces acting on the cutter on the soil side.
