Abstract

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%.
