When performing various technological operations in crop production, the working bodies of tillage equipment in contact with the soil wear out under the influence of an abrasive environment. (Research purpose) The research purpose is in theoretical substantiation for a method for quantifying the wear capacity of soils with different abrasive characteristics. (Materials and methods) The article presents the evaluation of the abrasive ability of the soil by the wear of a steel rod vertically immersed in the soil and moving translationally. Authors used the standard rod of steel St0; geometric parameters of the worn rod are diameter d = 25-30 millimeters, height h = 250 millimeters; dynamic characteristics during the test are moving speed V = 3 kilometers per hour, distance of movement L = 100 meters. The worn rod sinks to a certain depth, moves in the soil at a constant speed. A device was used to determine the abrasive characteristics of the soil. (Results and discussion) The numerical characteristic of the wear capacity of the soil was determined as the physical value of the wear of the standard worn rod when moving in the soil as A=Q/L, grams per meter. The lower the value of this ratio, the less abrasive components are in the soil; based on the wear data of a standard rod, it is possible to obtain a characteristic of the wear capacity of various soils. (Conclusions) The proposed method allows us to determine the abrasive and wear characteristics of various types of soils. The results of the study make it possible to install working bodies on tillage machines in accordance with the type and wear capacity of the soil in which they will work, which will reduce the cost of their manufacture and increase the efficiency of the use of equipment.

Machines used in gardens do not fully comply with the quality indicators of tillage, especially in the near-trunk zones of fruit trees. Theoretical analysis made it possible to establish that the preferred protective distance in the aisle of the garden should be at least 0.20 m in each direction, and in the inter-barrel space of the boles along a row of 0.38 m and to establish the optimal width of the extension section of 0.55 m. As a result of the research, an original design of the deflectable milling section of the garden milling cutter with an autonomous hydraulic system was proposed and developed, as working bodies knives with special sharpening are used. The tracking system of the remote section is equipped with a double remote probe, when exposed to which the section is retracted to the required distance to protect the trunk of a tree. The use of a deflectable milling section of a garden milling cutter allows to increase the accuracy and quality indicators of processing in the near-trunk zones of garden plantings, while the density of the soil decreases on average by 24%.

The features of the process performed with root cutter and plant lifter, as well as the forces acting on their working bodies are examined. It was established that resistance to the root cutting increases with an increase in their number and diameter, but also depends on their mechanical strength. The studies obtained dependences of forces acting on the working bodies in accordance with their geometric parameters and specific application of technological process that can be used in the development of root cutters and plant lifters.
