FIELD: agricultural engineering, in particular, equipment for surface cultivation of soil. ^ SUBSTANCE: harrow has frame and teeth secured in pairs on plank which is pivotally attached to harrow frame. Such attachment of teeth allows said teeth to perform self-vibrations resulting from irregular deformation of soil by each of said teeth. ^ EFFECT: high quality of soil mellowing, improved fractionation of lumps over the entire volume of soil under cultivation process and self-cleaning of harrow from plant remains. ^ 3 dwg |
