A traction-driven tillage tool with low traction resistance has been developed. A decrease in the tractive resistance of the implement is achieved by transferring the main share of the power consumed by the implement to the process of loosening the soil through the tractor power take-off shaft (PTO) to the drive needle discs, which in turn create a pushing force. The efficiency of the technological process of soil cultivation depends on the kinematic mode of operation of each row of disk working bodies of the tractiondrive tillage implements. To optimize their kinematic mode of operation, a multifactorial experiment was carried out, which made it possible to establish the optimal values of such factors as the kinematic parameters of the 1st and 2nd rows of needle disks at the set operating speed of the unit.

The paper deals with the use of vibration vibrations in the restoration of the working bodies of agricultural tillage machines operating under conditions of increased abrasive wear. The analysis of the existing methods of their restoration is carried out, the substantiation of the use of vibration hardening treatment in repair production is given. The research carried out on the choice of the optimal parameters of vibration strengthening of the cutting working bodies contributes to an increase in the wear resistance and reliability of soil cultivation equipment. According to the research results, the change in hardness along the depth of the surface layer of cutting elements of the following agricultural tillage machines: plow shares, opener discs of grain seeders and cultivator paws was established. Optimal values of the main parameters of vibration processing of cutting elements of the specified working bodies are experimentally determined and substantiated, which reduce the amount of their wear: amplitude A and vibration frequency of the processing tool n, hardening time t. The change in the magnitude of linear wear along the width of the cutting elements of these parts is shown, as well as data on the intensity of their wear. Experimentally obtained data on the absolute and relative wear of the diameter and thickness of the blade of the opener discs, which made it possible to choose a more efficient technology for their restoration. According to the research results, it was found that the specified parts of soil cultivation equipment had the least wear value; they were restored by welding tires, plates or segments from steel 45, followed by surfacing with sormite and strengthened by vibration deformation. The results of the work will be used to develop technological processes for the restoration of other working bodies of tillage machines by the method of vibration deformation.

The research objective is to improve the quality of soil loosening using combined working bodies for surface moisture-retaining soil cultivation. The efficiency of accumulation and conservation of precipitation in the autumn-winter period depends on the method of post-harvest soil cultivation. One of them is the autumn surface water-retaining treatment, which makes it possible to increase the efficiency of the processes of accumulation and conservation of moisture due to the deeper loosening of the cultivated soil layer. During loosening and mulching, the top layer of the soil contributes to the accumulation and preservation of moisture not only in the upper but also in deeper soil horizons. However, the used tillage tools do not fully solve the problem of the high-quality performance of surface moisture-retaining soil cultivation. The article presents the results of studies of the degree of influence of geometric and technological parameters of the additional active cultivator on the quality of surface tillage. Based on the results of the research carried out, the technological process of performing the surface tillage operation has been improved and combined working bodies have been developed for its implementation.

The aim of the research is to improve soil tillage quality using combined working bodies in surface cultivation. There are various designs of combined tillage units including passive cultivators and active rotor-tooth working bodies cultivating land. However, an analysis of design and technological parameters of modern cultivators shows that they have a cumbersome design, required much metal and their quality indicators do not meet soil cultivation requirements. The article presents results of the studies on the influence of geometric and technological parameters of an additional battery of needle discs on land tillage quality. Using the research results, the land tillage has been improved and combined working bodies have been developed.

Tillage energy efficiency increase is one of the important tasks in improving the profitability and sustainability of agricultural production. The paper proposes to increase cultivation energy efficiency due to the use of traction-drive tilling implement with active working bodies, not creating a high traction resistance and not requiring a large towing weight of aggregated tractor. The analysis of the energy efficiency of soil cultivation using traction-driven tilling implements with active working bodies has been carried out, and theoretical dependences of the coefficient of efficiency of a traction-driven machine-tractor unit has been obtained. The possibility of increasing the efficiency of the unit by reducing slipping of the tractor wheels and losses on rolling of the unit has been determined, which has been achieved by transferring part of the power through the power take-off shaft (PTO) of tractor to the drive working bodies of tilling implement, which compensate for traction resistance of the implement and create a pushing force, reducing the resistance to rolling.

Article is devoted to the description and the analysis of the system-dynamic model of technological process of biogas production from multicomponent vegetable raw materials. A research objective – optimization of biogas production process from vegetable raw materials by methods of imitating modeling, finding of the optimal regimes of the simulated production cycle – the best ratio from the economic point of view between an exit of biomethane and rates of giving/replacement of the initial substratum depending on the composition of raw materials.In article models with a discrete and continuous cycle of production are considered, the description of the similar realization executed in the environment of multiapproach modeling of AnyLogic for model of technological process of anaerobic digestion of non-uniform multicomponent vegetable biomass is provided.The known stoichiometric model of production of biomethane is taken as a basis, her modification is made for a case of multicomponent raw materials (percentage division into conditional components – sugar, lignin and cellulose). Possibilities of modern software shells and environments of modeling in tasks of the complex analysis and optimization of the studied process are shown.During the conducted researches a row of non-trivial results on a choice of optimum parameters of an operation mode of the model bioreactor is received. For a case of the discrete process of up-dating of contents as parameters of optimization the frequency and a level of up-dating, and for the continuous flowing system – channel speed were selected.It is shown that the optimal values of the parameters from the point of view of the integrated output of the biomethane lie close to the cloud of critical acidification, which leads to the stoppage of the process. If the economic indicators are chosen as an optimization criterion, then we obtain optimal values of the parameters lying within the region of stable functioning of the model bioreactor.
