FIELD: agricultural engineering, in particular, equipment for cultivation of stony soil in spacings or for continuous cultivation of soil. ^ SUBSTANCE: cultivator has two rows of working tools formed as longitudinal springs. One end of each spring is bent to impart C-shape thereto, and cultivator hoe is attached thereon. Other end of spring serves as plow beam and is attached to frame. Each of working tools has flexible member made in the form of resilient clip. One end of each clip is connected to first coil of spring, and other end is connected to lower part of coil of free end of spring. Rigidity of clips is greater than that of springs. Cultivator of such construction shows good vibration during cultivation of soil to thereby reduce draft, and easily goes around obstacle due to deformation of any of plow beam, spring and clip. ^ EFFECT: improved quality of cultivation of stony soils and reduced metal usage. ^ 4 dwg |
