On the basis of the analysis of existing technical means for tillage in this article we propose a new technical means of vibration action including rectangular welded rack with hinge systems, adjusting the depth of tillage. Fixing of the working bodies and working bodies are made in the form of racks with chisels and arrow-shaped claws differ in that there is a shaped hole is made in the upper side of rack where a mounted solenoid is. It is mounted on a rack by means of casing and screws, and the solenoid is made in the form of a coil with a head and spring and communicated with the electrical system of the tractor via the relay-breaker and a regulator are located on the rack. This vibrating tool presumably will lessen the resistance of the soil affecting on the working bodies, will eliminate the sticking effect of elements of working bodies and thereby the quality of the soil tillage will be improved, it will allow to reduce energy consumptions of working process up to 30%, it reduces the emission of harmful substances from combustion of diesel fuel into the atmosphere. The invention relates to agricultural engineering and can be used for tillage on various agricultural backgrounds and with different densities

From a review of the literary sources it is revealed that the existing vibration exciters are classified into mechanical, electrical, hydraulic and pneumatic. One of the most promising areas of development and use of sources of vibrations for tillage tools are electrical exciters of mechanical vibrations namely solenoid with a metal core inside. Based on the analysis of existing technical means for soil cultivation we are proposed a new technical mean of vibration exposure for tilting the soil without or before ploughing. Theoretical regularities of change of draft resistance depending on the vibration amplitude and the mass of the vibration exciter were received in the studies. A structurally - technological scheme of the combined tillage combine with electric vibration exciter and a device for automatic regulation of the technological process of the work of tillage machine was developed. The proposed vibration tool will supposedly reduce the soil resistance force acting on the working bodies, which will reduce energy costs up to 20% for the technology process of soil cultivation; harmful emissions from the combustion of diesel fuel into the atmosphere were reduced. The proposed technical mean can be used for soil cultivation in different soil fertility under different soil density

In the article we have analyzed the expediency of application of the method of calculation of definition of supposed (not washing away) speeds of water streams on a limiting condition for the Kabardino-Balkarian republic; criteria for a choice of parameters of a modeling rain are proved

In the article, we have stated the agro-technical requirements to a pre-seeding processing of soil. The results of experiments of the combined soil-cultivating unit are resulted. Operating modes of the unit with optimum width of capture, uniformity of a surface of soil, quality of crushing the soils meeting agro-technical requirements are proved

The article analyzes the existing classification of leveling devices and their design features. We have found that currently the form of the seed layer is achieved with harrowing cultivation in 2 ... 3 tracks , leveling and packing rollers in 3 ... 4 passes units on the field, which leads to an increased cost of fuel, living labor, as well as compaction of arable and subsoil layers of the soil. We have also proved a constructively scheme of a com-bined device capable to form the seedbed in accordance with agronomic requirements in a single pass

In the article, we have considered the questions of mathematical modeling of a combined soil-cultivating unit. Theoretical dependences and rational values of parameters and unit operating modes are received

This article considers the criteria of the efficiency of means for antierosion processing of soil with reference to industrial-economic conditions of the Kabardino-Balkarian republic

In this article, we have given a short review of scientific bases of designing of blocks and module cars and some perspective works for opening new possibilities of increasing the efficiency of technologies of intensive mountain and foothill gardening

This article considers factors which are necessary for considering at application of the minimum processing of soil. The scheme of power saving processing of soil and the scheme of the minimum processing of soil in a crop rotation with good water penetration are offered

In the article, the results of the analysis of agrometeorological factors of formation of a crop of long-term cultures are resulted. The regressive correlation analysis of the given conditions and growth of bean and cereal grasses has allowed to establish high correlation dependence between change of a crop and number of days of growth for cereal herbage. It is noticed, that change of the efficiency of the bean is less closely connected with time of formation of herbage, than cereals. Also, for fertilized bean and cereal the correlation factor between the crop and the term of growth of the grass is higher, than for not fertilized ones. The backward correlation dependence between the changes of the maintenance of a raw protein, ashes in a forage from the first hay crop of cereal herbage and, accordingly, the sum of temperatures more 5°С is established
