The following article presents the results of an experimental definition of the parameters of the active tool of a cultivator with a frame in the form of a flexible tubular element, having a leak-proof hollow tube with a non-round cross-section. By supplying the cavity of the frame with discrete pressure, the free end point with the cultivator point is forced to ripple, which allows the optimal vibration conditions of the cultivator to be established in various physical and mechanical soil properties. It is concluded that the elastic response of the flexible tubular element has a nonlinear nature. This research established the characteristics of the amplitude frequency, the resonance frequency and the speed of the cultivator. Two operating modes have been revealed: pre-resonance mode, having a range of 8 to 11 Hz, and post-resonance mode, having a range of 14 to 31,5 Hz.
