The paper highlights efforts by major global engineering companies to develop agricultural robotic systems, with a particular focus on universal unmanned mobile energy vehicles designed to perform technological operations autonomously. Analysis of current machinery for harvesting and preparing flax straw indicates a lack of sufficient automation and robotization in these processes. Among the operations involved in flax harvesting, turning is defined as the least energy-intensive. In this regard, research has begun on the development of a remotely controlled, self-propelled flax windrow turner, with potential for further adaptation to autonomous operation. (Research purpose) The study aims to substantiate the optimal operating modes and develop a power electrical circuit for a remotely controlled, self-propelled flax windrow turner equipped with an electric drive. (Materials and methods) The study provides a theoretical basis for the conveyor's linear speed in relation to the rectilinear motion of the flax turner. (Results and discussions) The study identified the following operating modes for the flax windrow turner: the conveyor's angular velocity was determined to be 4.63 radians per second, with a machine speed of 2.78 meters per second. Considering the machine's weight, 7.00-12 F-42-1 drive wheels were selected, with tires that offer excellent road traction and maneuverability. The drive wheels had a load index of 133, an outer diameter of 660 millimeters, and a profile width of no more than 195 millimeters without load. Additionally, a power electrical circuit was designed for a remotely controlled self-propelled flax windrow turner. (Conclusions) The study determined the operating modes for an electrified radio-controlled, self-propelled flax windrow turner and proposed a powered electrical circuit for designing the units and assemblies of machinery used in flax straw harvesting.

Abstract. The article reflects the problems of stimulating the development and implementation of advanced technologies in the field of agro-industrial production in general and in flax growing in particular. The mechanism is proposed, which is based on the use of the entire complex of financial, credit, economic, investment, tax and other instruments of influence on the activation of demand for scientific and technical products with a direct mechanism of state regulation and support. Relevance. One of the problems of the development of the agro-industrial complex is the existing model of the functioning of the economy, in which there are no sufficiently effective incentives for private capital investment in the acquisition of advanced developments in agricultural and agro-industrial production. The justification and application of a financial and economic mechanism to stimulate the introduction of innovative technologies in flax production has now become simply necessary to ensure technical and technological modernization at the expense of domestic developments of research centers and private companies, which is due to the sanctions imposed against our country and the growth of international tension. The problem of finding a mechanism to stimulate the allocation of long-term funds for the acquisition of advanced technologies is becoming particularly relevant. The purpose of this study is to propose a financial and economic mechanism to stimulate the introduction of advanced technologies in the flax industry of the agro–industrial complex of Russia, the tools of which will increase the level of innovation activity of economic entities of the flax complex. Methods. In the course of the study, methods of comparative, abstract-logical, functional-cost analysis, expert evaluation were used. Results. The article proposes a financial and economic mechanism to stimulate the introduction of advanced technologies, the tools of which will significantly increase the level of innovation activity of economic entities of the flax-growing subcomplex. In addition, the use of the mechanism of interaction between development institutes (VEB) and endowment funds proposed for use in industry science creates prerequisites for expanding the financing of research developments in flax production. The scientific novelty is in the proposal and justification of a new option for the interaction of development institutions within the financial and economic mechanism for stimulating the development and implementation of innovations in the agro-industrial complex (flax industry).
Relevance. The concept of precision agriculture call for the use of physical and mathematical, technical and software tools for obtaining and processing information about agroecosystems, as well as for the implementation of agricultural practices directly in the field. To date, there are quite a few software products that can control the production of crops, in particular, the management of differentiated fertilization and compliance with elements of cultivation technology. The purpose of our research conducted over two years was to develop and test in real field conditions algorithms for the functioning of the module of the information and analytical system of crop management for specialized crop rotations involving flax.Methods. The objects of research were the elements of the information and analytical management system for resource-saving production of crop production "Vash urozhaj" (IASUR) and flax-long-lived variety Tonus (selection of the FSBI FNC LC). The experiment used an electronic field map in kml file format containing the coordinates of points, quantitative characteristics of indicators of the content of nutrients and chemical elements in elementary areas within the surveyed spatial object, a technological map of the cultivation of flax, developed specifically for this variety, task maps for the application of solid and liquid fertilizers in .csv file format.Results. Developed and formed in the information and analytical system "Vash urozhaj" electronic technological map of the cultivation of flax-long-legged variety Tonus, containing a list of technological operations, timing and quality characteristics of their implementation, including a possible set of machinery and equipment. The possibility has been tested and the effectiveness of the module for obtaining climatically secured flax yield has been determined — the planned estimated yield for this flax variety at the pilot site is 4.3 c/ha. When cultivated according to the technology adopted in the Federal Scientific Center of Bast Cultures, introduced into the agroplatform, a yield of 4.0 c/ha was obtained. The yield deviation by 6.98% relative to the calculated one is due to the weather features of the growing season of 2021.
