The article discusses the sustainability dynamics in the longitude-vertical plane one trailed harrow section designed for fallow treatment. Deviation this dynamical system from the horizontal plane have accepted as the main estimated parameter. Theoretical studies have allowed received such as results. The fewer the distance between row tines of zigzag harrow section, the fewer its deviation amplitude and phase from the equilibrium state. When the attachment point coordinate of the harrow dragbars is increased from 0 to 0.2 m, its angle and time deviation from the equilibrium state is half as many that it is the desired result. When the harrow section has rational design parameters, its turn angle in the longitude-vertical plane does not exceed -3o, and time its output to the equilibrium state does not exceed 16 s. On soils with light grading, which have a low value of the vertical movement resistance coefficient of the harrow tines, time its output to the equilibrium state is reduced from 16 to 0.7 s.References
