The existing technical means of harvesting chicory roots do not provide the necessary indicators of the quality of digging root crops according to the agrotechnical requirements for root harvesting machines. Reduction of losses of root crops and their damage is provided by the use of a combined single-disk spherical digger, which combines a spherical disk and a loosener placed behind it and in its area of operation, which is installed on the riser of the disk. The article proposes a developed mathematical model that describes the movement of the soil layer along a spherical disc and that allows analytically determining its dynamic characteristics and technological parameters of the root crop digging process. The obtained results of the study are partially a supplement to the existing methods of substantiating the parameters of the working processes of root harvesting machines.
