Improving the operational and quality characteristics of soil tillage working bodies is an important factor in ensuring high yields and rational use of energy resources. It is known that insufficiently high-quality soil tillage can reduce yields by 15-30%. At the same time, the efficiency of soil tillage machines is reduced due to the rapid wear of their working bodies. Thus, the level of wear of the latter directly affects the productivity of the units.
To determine the permissible level of wear of arrow-shaped cultivator tines, which can be expressed in the area worked or the distance traveled, it is necessary to take into account the degree of wear of the blades, which affects the main indicators of their work. The availability of such data allows us to substantiate the optimal service interval for arrow-shaped cultivator tines, that is, the period of their most effective use, which emphasizes the relevance of the conducted research.
According to the results of experimental studies, it was found that with an increase in the radius of the edge of the blade of the paw r from 0,1 to 0,5 mm at the speeds of movement of the arrow-shaped cultivator paw 6, 8 and 10 km/h, the specific resistance increases by 11,98%, 12,00% and 12,02%, respectively, and the increase in resistance is 0,185; 0,256 and 0,375 kN/m, respectively. The intensity of the increase in resistance with an increase in speed from 6 km/h to 8 km/h is 36-38%, and in the range from 8 km/h to 10 km/h – 47-49%.
To ensure the set depth of cultivation in accordance with agrotechnical requirements, it is necessary to check the depth of cultivation and adjust it every 75 km of the path traveled by the arrow-shaped cultivator tine or 9,36 hours of clean operation of the TIGER MATE 2-12 unit. The uniformity of the depth of the path remains within the permissible values (=37,5%) with a radius of the edge of the tine blade up to 0,5 mm. A satisfactory level of root system undercutting (94-96 %) is observed with a blade radius of 0,3-0,4 mm, provided that the recommended speed of movement of the unit is not less than 8 km/h.

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.
