The article considers the possibility of using a potato harvester with an unloading device. The principle of operation of an unloading device based on a potato harvester is presented. The unloading device of the root-harvesting machine allows to prevent damage to tubers by damping the speed and lowering the height of the falling heap due to the use of the unloading gutter equipped with a lifting-lowering mechanism made of two differently inclined flat sections, on the inner surface of which, across the gutter, elastically deformable elements are fixed in the form loop absorbers. A group of authors carried out a comparative assessment of the tests of the basic model of the AVR Kolnag potato harvester Spirit 6200 and its improved experimental version with an unloading rating device. The studies were conducted on the fields of the Danko farm of the Lukhovitsky district, Moscow region in 2018 - 2019. Harvesting was carried out alternately from several fields. According to the data obtained, it was found that the level of damage to potato tubers when using the developed experimental version of the unloading device of the potato harvester is 2.1%, which is lower in comparison with the basic model of the harvester. The obtained results of field studies of the experimental unloading device confirmed the results of previous theoretical calculations and laboratory studies, including the high efficiency of the developed device compared to the serial analogue
