The issue of increasing the efficiency and reducing the energy consumption of the technological operation of unloading stem fodder (silage and haylage) from trench storage by block-batch method, due to the development and justification of parameters and modes of operation of the adaptive hydraulic drive system. Recommendations for determining the range of speed control of the working bodies of the mechanism for separation of stem forages on the basis of the developed system of hydraulic actuators of the separator mechanism with maintenance of energy saving mode of the pumping station and investigated nonlinear mathematical models mechanism and features of functioning of executive hydraulic motors of drives of the cutting mechanism in the mode of adaptation to real character of process of separation of a stalk forage. According to the results of mathematical modeling rational values of parameters of the developed hydraulic system of the mechanism for separation of a stalk forage corresponding to area of steady work of system are established, influence of components of hydraulic units of system of hydraulic drives of the separator mechanism regulation of speeds of the working bodies which are put in action by executive hydraulic motors.
Based on theoretical and experimental studies, it was found that reducing the width of the working edges of the spool leads to the most effective expansion of the technological range of speed control of the separation mechanism driven by the hydraulic motor - cutting mechanism and hydraulic cylinder - drive P - shaped frame.
As a result of research of influence of parameters of the developed hydraulic system of the mechanism for separation of stem forages on the range of technical regulation of speed of working bodies, constructive and technological parameters of the developed hydraulic drive are revealed. Determining the most optimal values of these parameters will increase the sensitivity and efficiency of the proposed hydraulic drive mechanism for the separation of stem forage. According to the results of the research, recommendations for the choice of structural and technological parameters of the developed hydraulic system of the mechanism for the separation of stem forages are provided.

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.
