The article presents the results of theoretical and experimental studies of the process of removing a damaged soil layer inside a crater by means of a specially developed working tool. The structural scheme and the general configuration of the working tool are described in detail. For performing the technological operation, the tool was mounted on the boom of an excavator, which provided the required positioning, movement trajectory and interaction with the treated soil surface. The design of the working tool includes the use of channel flanges and angle-section elements that ensure gradual layer-by-layer cutting, separation and removal of the damaged soil from the inner surface of the crater. Such a design makes it possible to control the depth of soil removal and to reduce excessive disturbance of the underlying undamaged layers.
To determine the soil cutting force and to evaluate the nature of the mechanical loading during dynamic experimental studies, an electronic dynamometer equipped with an SBA interface was used. The dynamometer strain-gauge sensor was installed directly on the brackets of the working tool, which ensured continuous and reliable registration of force parameters during the cutting process. The obtained experimental data made it possible to assess the actual loading conditions of the tool and to compare them with the values predicted by the theoretical model.
A comparative analysis of theoretical calculations and experimental results was carried out. It was established that the discrepancy between the calculated and experimentally measured values of the soil cutting force ranged from 4.5 to 8.6%. Such a level of deviation indicates a sufficiently high adequacy of the adopted mathematical model to the real technological process. The comparison also confirmed that the previously determined values of cutting force and energy intensity for soil removal by the channel flanges and angle-section elements adequately describe the actual loading pattern during the cleaning of the damaged soil layer inside the crater.
The obtained results can be used for further improvement of the working tool design, substantiation of its principal geometric and operating parameters, optimization of cutting modes, and reduction of energy consumption. In addition, the developed approaches may contribute to increasing the efficiency, reliability and technological effectiveness of mechanized soil-cover restoration operations under conditions involving local soil damage and crater formation.

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.
