DISC HARROW SECTION Russian patent published in 2023 - IPC A01B21/08 A01B13/16 

FIELD: agriculture.

SUBSTANCE: disk harrow section contains a bearing assembly (1) with a stand (2) and a shaft (3), on which needle disks (4) are installed on one side of the bearing assembly (1), and on the other side the first spherical disk (5) is fixed, facing the convexity of the sphere to the bearing unit (1). The second spherical disk (6) with its convex part is movably connected with the concave part of the first spherical disk (5). The disks (5 and 6) are mutually fixed along the radius by at least three fastening means (7). On the second disk (6), the holes of the fastening means (7) are made with grooves (8) providing one-sided displacement relative to the first disk (5). The radius of placement of the fastening means (7) and the grooves (8) on the second disk ensure its displacement relative to the first disk (6) to control the depth of the water-retaining grooves.

EFFECT: increased operational and technological performance of the disk harrow section.
