The article presents the construction and manufacturing of working screw harrow bodies, as well as the developed experimental setup for experimental studies, presents the methodology of research to determine the traction resistance of the working body. The variations of traction resistance force Px from the speed of harrow movement V, at different values of the angle of attack β of working screw bodies and working depth h are plotted.
