Technological innovations and radical products that drive the whole world forward can sometimes have an impact on different areas than planned. The drones ‘ positive impact on innovative agriculture has yet to be manifested in the stages of land and seed preparation. Advanced drone technology enables realistic 3D maps to be created, leading to soil analysis and seed development. Drones successfully manage the seed planting process in the soil. Furthermore, thanks to advanced imaging techniques and special thermal sensors, which part of the field needs water and where nutrients need to be supplemented easily can be determined.

The article substantiates the urgency of the eco-anthropogenic component of national security both of the state as a whole and of its regions. The types of interaction between society and the environment are determined. It is suggested to consider the ecosystem as a complex combination of flora, fauna and dynamics of natural systems and processes, which interacts with social institutions and power structures. The concept of environmental imbalance is formulated as a real threat to the disruption of life support mechanisms and the creation of obstacles to the economic and social development of the country, improving the quality of life of the population. The main threats to the technogenic security of the country are identified.

Promising energy technology means for controlled traffic farming are wide span tractor (vehicles). The effectiveness of the practical use of wide span tractor (vehicles) depends on a sound scientific base or theoretical frameworks, concerning the study of their technological properties. The article presents the theoretical basis of the dynamics of plane-parallel movement wide span tractor (vehicles) in the horizontal and vertical plane as well as its cornering. Developed the theory of plane-parallel movement wide span tractor (vehicle) allows for the justification of new schemes, design parameters and operating modes with acceptable controllability and stability of motion in the horizontal plane. Ride wide span tractor (vehicles), as a dynamical system, moving through the traces of permanent tramlines significantly depends on the characteristics of the irregularities of the longitudinal profile. The desired character of the internal structure of the longitudinal profile laid tramlines is almost possible to obtain the appropriate technology for its formation. Quality testing of dynamic system input perturbations, which are irregularities of the longitudinal profile permanent tramlines and the unevenness of the traction resistance of the soil, depends on the scheme and the constructive and other settings wide span tractor (vehicles). A significant impact on the smoothness of the latter renders the rigidity of the tire support wheels, the magnitude of which can be influenced, within certain limits, by changing the air pressure in them. Improve driving dynamics the technological part of the wide span tractor (vehicles) is observed by increasing the rigidity of the tire its supporting wheels and operating mass. The offered new scheme of the turn of a wide span tractor (vehicle) for controlled traffic farming on the turning strip by turning the undercarriage, using the steerable wheels from its one board around the turning centre arranged in the centre of the space between the wheels from the other board, allows shifting of the tractor, simultaneously with the turn, to the next operating position with better kinematic parameters. In addition to it, the improvement of the turnability characteristics is achieved at such a design embodiment of the wide span tractor (vehicle) when the relation of its wheelbase to the width of the wheeltrack is as small as possible.

The traditional approach in many agricultural facilities has been to keep machines running to increase production revenues, often with consequences to assets – consequences that result in higher maintenance costs. Autonomous maintenance is a reliability initiative that provides alternative to this dilemma.

Many people are exposed to whole-body vibration (WBV) in their occupational lives especially drivers of vehicles such as tractor and trucks. The vibration-induced injuries or disorders in a substructure of human system are primarily associated with the vibration power absorption distributed in that substructure. Absorbed power is defined as the power dissipated in a mechanical system as a result of an applied force. The article presents the results of dynamic load analysis of the tractor mower set. The amount of absorbed power by the tractor’s operator, based on physical models have been calcu- lated, as a function of operating speed of tractor mower set.
