To carry out each test, it is necessary to use instruments capable of measuring with the necessary accuracy. A TCh 10-R tachometer was used to measure the number of revolutions of the eccentric shaft. In our experiments, the number of revolutions of the shafts was changed by changing the diameter of the pulleys and using an electric motor. The performance of the device was determined by the formula presented in the work. 100 kg of seed was transferred from the supply hopper in the set number of rotations. Each test was repeated five times. It was found in the tests that the number and time of rotations were selected correctly for production efficiency.
