FIELD: agriculture. SUBSTANCE: share has seed guide mounted on drill frame, tine with wedge-shaped front surface, A-hoe and two needle-type disks positioned in front of tine in fork rigidly attached on tine. Needle-type disks are positioned at an angle to direction of advancement equal to half the angle of A-hoe. Disk shafts are interconnected by flexible link so that disks are angularly offset by half pitch of needles on disks. Intersection point of disk shafts is positioned in vertical plane extending through mid portion of arc of front surface. Paths of rotation of left and right disk needle ends intersect each other in front part and are positioned on A-hoe section line. EFFECT: increased efficiency, reduced draft of share and uniform seed embedding depth. 3 dwg
