The efficiency of cutting the bud, digging and cleaning of roots from impurities depends not only on the design and parameters of working bodies of the root harvesting machine, but also on the agrobiological and physico-mechanical characteristics of roots during harvesting. The choice of design of the working bodies and adjustment of parameters and modes of operation of the main working technological modules, or the module for cutting of a hyphen, digging and clearing modules of self-propelled root harvesters are regulated by dimensional parameters and the form of root crops and physical and mechanical condition of amniotic soil environment. The purpose of the work is to make further improvement of the methods and techniques of optimization of the structural and kinematic parameters and modes of operation of the working bodies of transport and technological systems and modules of root harvesting machines. The article presents results of the field experimental studies of the mass and thickness of the layer of sticky soil on the body surface of dug fodder roots, sugar, table beets, carrots and chicory roots depending on their agrobiological characteristics (root diameter, root length, root depth and physical root environment soil condition (soil moisture). The roots were dug by the working bodies of the combined digger, which consisted of a one-sided spherical disk, a drive shaft with cleaning elements, and a loosening device. It is established that the mass of sticky soil varies from 10… 210 g for fodder beets, 50… 250 g for sugar beets, up to 90 g for table beets, up to 70 g for carrots, 20… 360 g for chicory roots.
