The article presents the results of experimental studies of the performance of a paddle feeder for a continuous root crop loader. The studies have obtained regression equations and graphical dependences of productivity when changing the angular speed of the blade rotation, the speed of the forward movement of the feeder with the loader, as well as the radius of the cylindrical blades. The results of experimental studies show that the performance of a paddle feeder of a continuous loader when working with potatoes is in a non-linear dependence on the studied parameters and is described by a second-order equation. The values of the studied parameters are established, at which the performance is of the greatest importance.
