Elaboration of the Methodology for Calculating the Brush Cutter with Passive Operating Element

– The physical process of interaction of the working member of the brush cutter with trees located on the path of the machine movement is considered. In the development of existing ideas set out in the textbooks, the method for calculating brush cutters with a passive working body is refined, based on a detailed analysis of the acting forces. Recommendations for the calculation and selection of the parameters of the working member of the brush cutter are presented. Dedicated to the memory of our mentors and outstanding scholars, Nikolai Iakovlevich Kharkhuta (Leningrad Polytechnic M.I. Kalinin) and Konstantin Aleksandrovich University), who made significant contributions to development of a theory of interaction between working attachments of construction and road machinery and treated environment.
