CHOOSING A REASONABLE GRIP WIDTH OF ROTARY RAKES WITH CONTROLLED RAKES
Dmytro Kondratuk – Candidate of Technical Sciences, Associate Professor of the Department of Agroengineering and Technical Services of the Vinnytsia National Agrarian University (3, Solnyshchaya St., Vinnitsa, Ukraine, 21008, kondratuk@vsau.vin.ua, https://orcid.org/0000-0003-1827-1717).
It is advisable to use rotary rakes with controlled rakes for raking hay in the windrows. On the agricultural machinery market of Ukraine, foreign companies offer models of rotary rakes with controlled rakes, which differ in the width of the grip from 2.8 to 14.0 m, the number of rotors and other features. This creates difficulties in choosing a rake with a rational width of grip. It is possible to choose the rational width of the rake, based on the estimated volume of hay harvesting in the farm and operational costs of money for the performance of mechanized work. It is obvious that with a rational grip width of the rake, operating costs will be minimal. The purpose of the work is to reduce operating costs when harvesting hay by developing an algorithm for choosing a rational rake width with controlled rakes. It was established that the given operating costs for hay raking decrease as the width of the catch increases from 3 to 6 m. At a width of 5-7 m, the minimum values are taken, and with further growth, the width of the grip increases. This is explained by the fact that with a small grip width of rakes, they have low productivity, which leads to relatively high operating costs. The increase in specific operating costs with a width of more than 6 m is associated with an increase in the cost of the rake. In order to reduce the cost of hay, it is advisable to use a rake with a width of 5 to 7 m for its raking. The necessary width of the rake can also be selected based on the estimated amount of hay harvested. Graphical dependences of the change in standard rake production (product of productivity per standard annual loading) on the width of the grip were obtained. It has been established that under the condition of one-time use of a rake with a grip width of 7 m, it will allow harvesting from 2,500 to 2,800 tons of hay per year.

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.
The journal consistently adheres to the principles of open science. All published materials are distributed under the Creative Commons Attribution 4.0 International License (CC BY 4.0), ensuring open access to research results provided proper attribution to the authors and the original publication is maintained.
At present, Technology, energy, agriculture transport AIC is an authoritative professional scientific journal (Category B), providing a platform for the publication of fundamental and applied research results, promoting the integration of education, science, and industry, and contributing to the advancement of engineering and technological support of the agro-industrial complex of Ukraine.
