Analysis of the level of mechanization in the cultivation of soil in the planting of seedlings and seedlings of forest and garden crops necessary for the destruction of weeds, soil content in the loose state, making the root layer of the soil of nutrients, etc., revealed that inter-row processing has a 100% level. However, it remains untreated rows of plants that includes the protection zone, which requires to perform operations on rows in significant expenditures of manual labor, constituting 40...50 people/hour in 1 hectare. The optimum variant of technology of planting care of seedlings seedlings of forest and horticultural crops would be the conversion of cultivators KRN working body, allows to conduct processing of soil in the rows of plants. At the same time, operations of soil treatment are carried out both in row and row spacing. All known methods of tillage in a row require the use of special working bodies that provide loosening of the soil in a row and cutting weeds. Such working bodies should provide the necessary protective zone around the plants. The developed design of the working body is installed on the row cultivator KRN over the processed row, which provides one-time processing of row spacing and rows. The article presents the results of theoretical studies of a special working body.

Results of theoretical studies of dynamics of the machine-tractor assembly taking into account the influence of a bearing surface profile were presented. It was established that in the course of operation, the machine-tractor assembly is exposed to a number of external factors leading to a change of vertical loads on the chassis and the engine. Mathematical models of dynamics of a tractor and a machine and a tractor unit consisting of a tractor of pivotally connected arrangement and a trailed sower were constructed. Such models make it possible to study dynamics and oscillatory processes of multi-element units. A mathematical model of tractor wheel dynamics was formed. Speeds and angles of orientation of elements of the machine-tractor assembly in space were determined. Influence of profile of the bearing surface on the unit elements when moving in the field prepared for sowing and the field after plowing was calculated. Theoretical studies of the influence of the bearing surface profile on dynamics of the machine-tractor assembly were performed on the example of KhTZ-242K tractor and Vega-8 Profi sower (Ukraine). When moving, the sower frame has a smaller amplitude of vibration accelerations than that of the tractor. Accordingly, the tractor has higher oscillation energy because it rests on the ground through its wheels having appropriate stiffness. The sower moves with its working bodies immersed into the soil which leads to a decrease in the amplitude of oscillations. The highest energy of amplitude of oscillation accelerations of the sower frame in the vertical direction was observed at frequencies of 15.9; 23.44; 35.3 and 42.87 Hz. It was found that the increase in working speeds of agricultural units leads to the fact that oscillations of all components reach significant values. This entails an increase in dynamic loads on soil and, as a consequence, its compaction

The basic principles and methods of classical mechanics, mathematical analysis and statistics were used in this study. Theoretical studies were carried out to determine the parameters of the guide knife and the loosening pointed leg of the machine. It is established that to ensure the required value of the crest height with minimal energy consumption, the height and length of the guide knife should be 8 and 15 cm, respectively, the angle of the knife blade to the horizon - 30º, the longitudinal distance from the toe of the ploughshare body of the knife toe – 13 cm. To ensure the required crumbling of the soil, the width of the pointed loosening paw should be 15 cm.

Theoretical studies of the milling tillage working body, in particular, dynamic properties under conditions of periodic external load, are substantiated and the main technological parameters are substantiated, and energy performance indicators are analyzed. The following data were adopted as the initial data for theoretical studies of the milling working body: the size of the row-spacing and strips, the dimensional characteristics of the root and stem residues. Theoretical studies of the milling machine gave such justified results: the diameter of the milling drum Dfr.bar = 0.3 m, the rotation frequency of the milling drum nfr.bar = 190 ... 430 hv-1, the number of installed knives on one disk n = 4 pcs, the rotating speed Vob = 6.59 m/s. Rational parameters and operating modes are justified: milling power Nfr = 19.3 kW, torque on the milling drum shaft Mkr = 0.45 kN·m. Theoretically substantiated milling working body is implemented in the development of a combined grinder of plant residues of thick-stem crops. The investigated working body, which performs the technological process of grinding compacted plant residues of thick-stemmed crops with the proposed technology, will allow us to further substantiate in more detail the mathematical model of the combined method of processing the field clogged with plant residues and determine the structural and technological structure of the grinder. The further development of the theoretical foundations of grinding plant residues and soil, in particular milling working bodies used in combined units, has been obtained

Used in Russia mechanized technology in the vineyards characterized by an increase in en-ergy costs 2.5–3.4 times compared to foreign countries. Most of the energy costs account for processing vineyard soil. It is necessary to improve the methods of mechanized soil cul-tivation in vineyards in terms of reducing en-ergy consumption while maintaining quality. The aim of the study is to develop mecha-nized universal technical means and working bodies for processing row-spacing of vine-yards with the lowest energy consumption without damaging the root system of the bushes. The designed multioperational chisel is capable of performing tiered tillage in ac-cordance with the architectonics of the root system of the bushes. Loosening depth 9–45 cm. The original design of the working bodies of the chisel with an additional degree of freedom provides a reduction in traction resistance by 12–14% and specific energy consumption by 1.2 and more times. Chisel complies with agrotechnical requirements in terms of fulfilling the quality indicators of the technological process. The number of frac-tions up to 50 mm 57.5–76.5 %, lumps over 100 mm 8–9 %. Universal design multiopera-tional garden and vineyard chisel allow its use in technologies of cultivation not only fruit, but also grain and row crops.
