The design features of most modern tillage implements determine a characteristic aspect of their operating processes associated with the oblique-angle cutting regime applied to the heterogeneous and stochastic structure of the soil. Therefore, a detailed study of soil deformation and failure under oblique cutting conditions is important for substantiating and optimizing the structural and operational parameters of innovative tillage machinery at the stages of development, design and further practical application. The paper presents the results of a graphical-analytical investigation of the oblique cutting characteristics of a “flexible wire” subsoiler intended for loosening over-compacted sub-arable soil layers and eliminating the negative effects of a plow pan.
Based on the obtained research results, the structural layout of the proposed subsoiler was substantiated. Its design incorporates a double-acting mechanical damper installed within the “flexible string” circuit. The application of this element makes it possible to significantly reduce the draft resistance of the subsoiler by promoting soil failure mainly through a system of longitudinal and transverse shear cracks propagating toward the open surface of the soil half-space. This operating principle reduces unnecessary compaction and improves the energy efficiency of deep soil loosening.
The installation of the mechanical damper induces controlled self-excited oscillations of the flexible working element, thereby ensuring stable oblique cutting along the entire contour of the “flexible string”, regardless of local changes in its curvature during interaction with the soil. It was established that the use of an 8 mm gauge G80 grade short-link load chain manufactured in accordance with ASTM A391 as the flexible subsoiler string provides an average transverse dimension of approximately 20 mm. Furthermore, a tillage unit consisting of a PLN-5-35 plow combined with the developed flexible subsoiler, designed for loosening a sub-plow layer with a plow-pan thickness of 100 mm, ensures an operating depth of h = 0.35–0.40 m. The obtained results can be used to improve the design of deep-loosening implements, reduce draft force and energy consumption, and increase the efficiency of till.

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.
