Аннотація: The article is devoted to the most pressing problem of developing a dynamic mathematical model of a hydraulic drive for folding and unfolding a wide-cut agricultural unit and research. To achieve this goal, a system analysis of the processes involved in the hydraulic drive, which indicates the transfer of the unit from the transport position in operation, was carried out. Monitored by hydraulic systems. An examination of known mathematical models and their methods was carried out. An analysis was carried out and trends in the development of agricultural units and equipment for soil treatment. Their advantages and shortcomings are analyzed. It is noted that one of the direct developments of current agricultural machinery is an increase in working width. This trend is justified from the point of view of the economy of burning, a reduction in the number of passes of the unit and a change in the strengthening of the soil, which positively flows into the soil and promotes its fuelability. To a few of these machines, the complexity of the maneuvers should be brought into account. To make it easier to maneuver around the turning method, it is better to equip these units with a system for transferring from the transport position to the operator. This system can respond to current situations, and itself: high speed, but the flexibility of the folding section, compactness. To complete this task, the hydraulic drive must be turned on completely. This drive has numerous advantages, such as compactness, high strength, ability to operate at high speeds and dampen vibrations. A hydraulic drive circuit has been designed to transfer the unit from the transport position to the operating position due to the incoming hydraulic motors. A mathematical model of the drive has been developed, which includes the balance of the drive and the forces that act on the working bodies of the hydraulic motors. The extracted results allow you to analyze in detail the processes in the drive and determine the optimal parameters to ensure efficient operation of the system.
