Abstract
The article presents the results of a field experiment of a developed controlled attachment device (UNU-3) as part of an aggregate with an MTZ-1221 tractor and a mounted cultivator KON-2.8 and provides recommendations for its use. It was found that when using a controlled mounted device, the range of variations in the numerical values of the deviation of the cultivator axis from the line set by the navigation equipment at the speed of the unit from 1.39 m/s to 1.94 m/s ranged from 0.08 to 0.04, which is 2-4 times less than without using the device, respectively. The process of functioning of a controlled attachment is described. It is determined that this device will increase the positioning level of the aggregated gun by minimizing the transverse displacement.
