FIELD: agriculture.

SUBSTANCE: invention refers to agriculture, and namely to cultivating machines. Working element includes disc with bearing assembly fixed on rigid support. Attachment device of support by means of hinge to horizontal axis and spring mechanism is conjugated to bracket. Bracket includes attachment part for bracket installation on load-carrying beam of machine frame. Attachment part of bracket is made in the form of cheeks with coaxially located holes for installation of axis of vertical hinge attaching the bracket to load-carrying beam of machine frame. Bracket is made so that it can be turned about axis on which centres of holes in cheeks are located. Distance from axis on which centres of holes are located to the flange between bracket cheeks is more than distance from the above axis to vertical flange of load-carrying frame beam, which is enclosed with attachment part. One of cheeks is elongated and hinged to adjusting rod arranged along load-carrying frame beam of machine and providing and fixing the specified turn angle of bracket and attack angle of the disc.
