“…The structure of repair and maintenance impacts using the example of grain harvesters is presented in Figure 3. It reflects the seasonality and short-term use of the combine for its intended purpose, characteristic of most agricultural machines [11]. The frequency of maintenance (MOT) of complex energy-intensive equipment is presented in Table 2.…”

Agricultural production in Russia solves the most important national problems - food security and import substitution. The conducted research substantiates the need to improve the engineering service of the agro-industrial complex through the introduction of modern innovative technologies. The article outlines the basic principles and technical means that determine the system of maintenance and repair of machines in the agro-industrial complex, as well as the mechanism of relations between manufacturers and consumers of technical means. Current issues of individual subsystems of the repair and maintenance base in the engineering service of the agro-industrial complex and the main groups of repair and maintenance impacts on domestic agricultural machinery were considered, and a relationship was established for foreign-made machines with all elements of maintenance, repair, modernization and disposal. Information is presented on depreciation rates and recommended distributions of the volume of repair and maintenance work by facility.

“…The monitoring of various ways to improve the productivity of agricultural machinery under conditions of the development of intelligent agricultural production showed [13] that conventional directions of increasing the concentration of energy, the size of working elements, and the movement speed had almost reached their resource capabilities. The power of already existing machines is not fully utilized due to the influence of the human factor.…”

“…We have established the dependence (13) of effort on the hydraulic cylinders' rods on the values of the normal reactions of the adapter's wheels, the effort on the hook of the device, the load factor on the wheels of the drive axle, the coefficient of the resistance to rolling, the operational weight of the device and adapter, the rolling radius of the adapter's wheels. It is noted that the values of the normal reaction of soil to the wheels of the adapter and the effort on the hydraulic cylinders' rods increase in proportion to the traction effort on the hook of the agricultural processor.…”

This paper reports a study into the possibility of using the chassis of combine-harvesters as a mobile energy device. The operational requirements for mobile energy technological devices for general purposes have been developed. The traction-coupling characteristics of the combine-harvester with an adapter that increases traction force have been investigated. The theoretical dependences have been derived of the motion speed, the power on a hook, the specific fuel consumption, as well as a factor of loading the wheels of the driven axle, on the traction force on the hook of an energy-technological device. It is noted that the use of the controlled axle with drive wheels reduces the slippage of the engines of the energy technological device. At the engine slippage level of up to 16 % an energy device, equipped with a driven axle with drive wheels, generates a traction force on the hook of up to 40 kN. Under the conditions of driving the axle by the hydraulic transmission mainline, the motion speed of an energy device decreases by 17.9 %, 28.5 %, 35.9 %, and 49.0 %, respectively, on gears I, II, III, and IV of the drive axle gearbox. The power on the energy device's hook is increased due to the corresponding increase in traction effort: on gear III, at a traction effort within 35-40 kN, the capacity on the hook is 68-75 kW. Under these conditions, the specific fuel consumption is 430-460 g/kWh at the device's motion speed within 1.9-1.95 m/s. The limits for changing the load factor on the wheels of the driven axle (not less than 0.2) have been determined, at which the requirements for control over an energy device are met. The specific fuel consumption (540-580 g/kWh) by a combine-harvester with a throughput capacity of 9-11 kg/s has been established, when using it as an energy technological device for general purposes at a motion speed of 1.7-2.1 m/s and a traction effort on the hook of 24-33 kN

“…Sensors provide the projected prototype MRC with information about the position of the object and indicate the direction necessary for movement to the intended target. A mathematical tool such as a Kalman filter [2] is used for control, which estimates the errors of directional stability and lateral movements of the wheels contained in the data on the position and speed of movement. During the experimental studies, it is assumed that MRC will be able to automatically follow the target course and harvest.…”

Nowadays, there are many technical and technological solutions to increase productivity in agriculture. One of such solutions is the use of the latest robotic mobile systems that can increase agricultural productivity. For the implementation of these decisions, sound concepts are needed to create control systems for agricultural unmanned mobile energy devices based on an analysis of current trends in the development of robotic mobile energy devices. This paper discusses various areas of the concept of creating unmanned control systems for a mobile energy device - a combine harvester, ensuring high-quality performance of technological operations of harvesting, including the directional stability of the combine harvester. The most effective version of the concept of creating a control system was selected.
