FIELD: agricultural engineering, in particular, two-disk shanks for grain drills. ^ SUBSTANCE: shank has carrier and T-shaped body. Rotating disks are fixed on T-shaped body by means of brackets. Disks are positioned at an angle to one another and are equipped with seed guides. Longitudinal part of body is fixed on carrier. Bracket with disks and seed guide is attached to transverse part of body for movement thereon. Adjusting planks are mounted on brackets, in parallel therewith, so as to change their position relative to brackets in vertical plane and fix them in certain position. Adjusting pins are fixed at ends of planks, beyond disks, above their center, perpendicular to advancement direction. Adjusting planks may vary their position in horizontal plane relative to adjusting pin. ^ EFFECT: improved quality of seed embedding into soil and wider range of usage. ^ 2 dwg
