A serious technological and economic lag of the domestic agro-industrial complex from the advanced world agriculture largely occurred in the past due to distrust and underestimation of the progressive capabilities of the rapidly developing latest innovative technologies (especially digital ones) both at the state level and at the level of farmers, which, as a consequence and led to their very slow and limited introduction into the country’s agriculture. Today, the most pressing problems of the Belarusian agro-industrial complex still remain: extremely costly agricultural production and its low efficiency; in general, most agricultural organizations of the republic still have a low level of profitability. So, as of the end of 2020, the level of profitability, excluding state support for all agricultural organizations included in the system of the Ministry of Agriculture and Food of the Republic of Belarus, amounted to only 1.7 %. In recent years, serious positive shifts have taken place in the state economic policy in relation to the latest highly promising technologies, so the most important direction of the state innovation policy of the Republic of Belarus for the coming five-year period is now the digital transformation of the traditional sectors of the national economy. The current level of domestic regulatory and legal regulation of various digitalization processes in the agricultural sector lags far behind the information, digital and other innovative technologies that are being widely introduced today, which are constantly developing and improving. All activities for the effective implementation of the latest innovative technologies are in dire need of legislative support at the level of timely and constant updating and modernization of the basic regulatory provisions of their regulations. To strengthen confidence in the latest technologies and their successful effective implementation in Belarusian agriculture and create a legal basis for international cooperation, and above all within the EAEU, the most important task today is to form an up-to-date regulatory framework. The formation of a system of legal regulation aimed at ensuring the transition to the digital transformation of the national economy is one of the important tools for implementing the directions of the modern state innovation policy of the country. The article describes a number of currently highly promising areas in the digital transformation of agriculture in the world.

Since the 30s of the last century, non-traditional (parallel) tribotechnics of non-standard tribotechnical materials have been developing to improve the performance of friction units of various civil and military equipment, which is especially important for worn-out machines and equipment in the agroindustrial complex Russian Federation. Its peculiarity is the tribo-processing of parts not in the manufacture of machinery and equip-ment, but the tribo-processing of friction mates only by the introduction of tribo-materials in the maintenance and repair of machinery and equipment. These tribomaterials are pre-ventive in the initial stage of operation of machines, equipment and repair and restoration, used instead of repair of friction units, acting not on oils, lubricants, but directly only on the friction surface during their work under high pressure and temperature. Among the repair and restoration of tribomaterials in the history of parallel tribotechnics preferred were a variety of mineral powders, enough effective, easy to prepare and use. They tested for the first time in many Leningrad research Institute (Mekhanobr, etc.), in IMASH, in do-zens of research institutes of the Russian Federation, and the wides-pread introduction of 80-ies was conducted by private firms: NPIF "EnionBaltika", SPC "Ruspromremont", NPTK "SUPROTEC", in many other civil and military organizations of the Russian Federation, Japan, Finland, China, France, Germany, Egypt, other countries of Europe, Asia, Africa, America. More than 1 million cars and tens of thousands of them have already been processed. other stationary equipment units in the civil and military industries. The results of tribo-treatment of mineral tribomaterials and sometimes unique, increase the resource of friction mates up to 3 times, increase the functioning of units, sometimes to the nominal value and even higher. However, the instability of triboactive private firms demanded technical service machines APK development of standard tribomaterials on the basis of a stable industrial products that are made in the FSBSI FNAC VIM.The objects of the study were: more than 80 mineral powder and engine oil triboactive.The subject of the study were: dependence of coefficient of friction steel tributary pin-on-disc load in the engine oils and oils with triboactive. The work purpose — development of an effective, of stable mineralogy and and tribotechnical properties of repair-recovery composition from waste products of mining enterprises. The starting material used mineral powders used waste mine "Saranovskaya", which in the Nanocenter GOSNITI dried in an electric Cabinet SNOL at 105 ºC, sifted on a sieve 100 microns vibrating screen "Analizzete 3 Pro", checked on X-ray diffractometer XRD 6000 with a library of spectra ICDD, crushed on a ball mill planetary "ACTIVATOR 2SL", again checked the diffractometer, examined on a metallographic microscope Olympus GX 51 and then tested on a tribometer TRB-s-DE with a steel tribopara "finger — disk" in oil M-10G2K in step loading to a pressure of 218 MPa at a sliding speed of 1 m/s and friction path 1500 m. According to the ICDD library, the X-ray phase analysis revealed the classical Aluminum IronMagnesium Si, Lisardite-1T [Mg₃Si₂O₅₄] with all its stan-dard characteristics in tribo composition as the main mineral. The other three minerals are secondary. Powder processing brightened, became pale gray-yellow, a large proportion of the particles of triboactive "Sarnowski" 1–5 μm, an average size of 2.3 μm with a few ag-glomerates up to 40 μm, which meets the requirements of tribology. Comparative tribolo-gical tests showed a high load carrying and anti-friction efficiency engine oil company Mobil, coincidence properties of serpentine triboactive CNT and MS-20. Good properties were confirmed by nanodiamond compositions of CARAT-M and CARAT-5. And tribotechnical composition "Sarnowski" revealed the best of serpentine and tribosystem brings oil M-10G2K the highest class of oil company Mobil. Prof. Ostrikov V. V. conducted 250-hour operational tests of the full analogue of the "Saranovsky" in diesel tractors MTZ-82, MTZ-1221, DT-75M. There was a general decrease in fuel consumption of tractors by 5–8 %, oil burn by 10–12 %, and smoke by 8–15 %. But the main thing-the iron content in the oils decreased by 20-25 %. This is indicative of the anti-wear property of triboactive, to increase the service life of diesel engines and confirmed known since the 90-ies of the effectiveness of unconventional tribology. It is revealed that tribotechnical composition "Sarnowski" with the mineral Lizardite 1T stable industrial waste from satisfactory, and the creation of artificial triboactive done. This composition can be used for CIP-repair of worn engine and power transmission. For hydraulic powder requires the separation of the fractions to 10 μm.

The article presents approaches to monitoring the technical condition of diesel air filters, considers options for using a prototype of an experimental counter-indicator to assess the current technical condition of tractor air systems using instrumental control tools. Recommendations are proposed for improving the efficiency of maintenance to prevent errors in the maintenance and diagnosis of the tractor air systems during shift maintenance.

The operation of machine-tractor units is always associated with increased vibration caused by external and internal disturbances, the most significant of which is the disturbance from the background when the machine-tractor unit moves along the irregularities of the path. At certain values exceeding the normative values, vibrations have an extremely negative impact on both the technical system and the human body. In order to reduce the magnitude of the oscillations occurring at the operator’s workplace, it is necessary to select the optimal characteristics of the elastic damping elements of the machine components and assemblies at the design stage of the machine springing system. The paper presents a simulation model developed in the Matlab/Simulink software package using the Simscape library, as well as a method for comparative evaluation of vibration protection of various variants of the springing system design on the example of a class 4 wheeled agricultural tractor according to the main vibration parameters: vibration acceleration, vibration velocity and vibration displacement at the operator’s workplace. Two variants of the tractor springing system design were subjected to comparative evaluation: two Bergkraft BK8508131 cab vibration isolators and two ZF MSEE30/15x44A2 cab shock absorbers with sprung and unsprung axles. The simulation model consists of concentrated masses with their elastic damping elements, an external disturbance block from the side of the road profile and an output block — a virtual set of sensors mounted on the operator’s seat; all blocks have a conditional mechanical connection with each other. A profilogram of a fi eld from under vegetable crops is set as a disturbing effect. The calculation result is presented in the form of a dependence of the main vibration parameters on time, visual analysis of which allows us to identify the most preferred design of the springing system from the considered ones. The simulation model is universal and can be used for comparative evaluation of springing systems of any components and assemblies of various wheeled vehicles.

The work reflects selected aspects of the main technological measures being carried out at specialized enterprises (sites) for the recycling of waste from the recycling of self-propelled machines in the agro-industrial complex (APC). Reflect the economic, technical, technological, environmental and social peculiarities of waste management in the utilization of energy-intensive equipment in the Russian APC. The recycling of agricultural machinery wastes in the Russian Federation’s IPA is still topical and many of them remain to be fully resolved. Large quantities of waste are generated from the use of agricultural machinery and further processing (recycling) is in the process of "artisanal" recycling. The formation of a state-of-the-art waste management system for the disposal of energy-saturated equipment in the APC is one of the most important tasks in strengthening the engineering unit of the APC. The main stages of the recycling process cycle for machine waste include: waste generation and accumulation; waste collection; transport; sorting; decontamination; recycling (use/treatment); disposal (storage/destruction); and site remediation. The creation in the next 2–3 years of a resource-saving ecooriented system "Agricultural Processing" with maximum use of existing enterprises of the engineering block of the APC will allow to return to circulation of secondary resources in the amount of 92–95 billion.

The article describes a number of highly promising modern trends in the development of agriculture in the world. Today, in European countries, the centralized management model in the development of rural areas and agribusiness still dominates, while the modern common policy approach of the EU and other European countries outside this union, in regional development is primarily to transfer as much as possible management functions at the regional level, this approach is also characteristic of the domestic model of agrarian development policy. The most important and effective tool (direction) for the modernization of any of the known control systems in the modern world is their digitalization. The digitalization of management in the agricultural sector at all levels, from the state to the small agribusiness entity, will not be an exception. Further digital transformation of management in domestic agriculture is a higher level of digital integration, which affects the most complex organizational changes in government structures and agribusiness, the results of the implementation of these tasks can dramatically affect the growth of profits in the agricultural business, the competitiveness of products and will allow the agricultural industry as a whole to go to the modern world technological frontiers
