Purpose: analysis of systems for automatic synchronization of bogies in line of multi-support sprinkler machines. 

Discussion. The hydraulic system for automatic synchronization of bogies into a line using irrigation water has the disadvantage that the elements of this system affect the operation of the hydraulic drive only during the movement of the hydraulic cylinder, and therefore they do not receive signals from this system, so the velocities of movement of the hydraulic cylinders of the bogies are different. This leads to the uneven movement of the bogies, which in turn leads to the overloading of the elements of the movement system and repairing of the machine itself. The system for automatical synchronization of bogies in line with a closed hydraulic system is cumbersome and unreliable, since the system of pipes with hydraulic fluid supplied to the spool valves runs throughout the machine under high pressure; the service life of the spool valve, which is subject to constant friction, is short. The electric system for automatical synchronization of bogies in a line is optimal, as it has no disadvantages, and therefore is used on most modern sprinklers. 

Conclusions. The results of the analysis of systems for automatic synchronization of bogies in a line of sprinklers showed that the following types of systems are currently used on multi-supply sprinklers: a hydraulic system using irrigation water, a system with a closed hydraulic system and an electrical system. An analysis of systems for automatic synchronization of bogies in a line of sprinkler machines showed that further research to improve them is required.
