Insufficient study of the characteristics of the material of harvested feed from herbs complicates the transition to more rational methods of work and restrains the creation of fundamentally new machines and technologies, which allows for reasonable to design equipment, choose the most effective ways of influence of working bodies on the material and ensure high quality of operations. The study of the physical and mechanical properties of agricultural materials is a prerequisite for the proper organization of the process and the design of machines.
Technological operations performed by feeding machines are aimed at changing the structure of these materials. In the process of processing, the hay is brought to a state that corresponds to agro -demands.
The type of working body and its parameters are determined by many factors: the necessary productivity, physical condition and nature of the material, quality and accuracy of processing, the efficiency of the machine and the level of its energy consumption.
The modern harvesting of legumes is aimed at improving the productivity of machines for their production, improving quality and feed value, introducing new methods of influence of working bodies on the material of the workpiece. Thus, the mathematical modeling of the work of the working bodies of feed harvesting machines should be based on the study of the physical and mechanical and technological characteristics of harvested feed mass with minimal nutrient loss and vitamins. Theoretical analysis of the processes of harvesting from herbs confirms the possibility of establishing estimated dependencies between productivity, energy costs and structural parameters of the working bodies of the machines, if the properties of the material are known.
Further development of prospective technologies and technical means in the field of feed harvesting requires a generalization of available theoretical and calculated research. This creates the basis for the emergence of new mechanization tools that can provide high productivity at minimal cost of material and energy resources per unit of quality feed.
The work analyzes the theoretical and calculated data of the functioning of the working bodies of machines in the process of influence on plant material during the harvesting of herbs. The calculations of parameters are related to the physical and mechanical properties of raw materials and agrotechnical requirements for the performance of operations.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
