Abstract
A cutting head, especially grass cutting head for a free-cutting device having a main body which essentially comprises two discs spaced axially from each other and rigidly connected with each other; between and approximately parallel to the discs are arranged at least two pivotally mounted, blade-like cutting tools which, during rotation of the cutting head, project beyond the peripheral edge of the discs and, because of the arising centrifugal force, align themselves radially outwardly. A pivot pin is rigidly connected with the cutting tool; the pivot pin extends upwardly and downwardly beyond the cutting plane, and is held approximately parallel to the axis of rotation and is partially surrounded by bearing seats of the discs; these bearing seats are located axially across from each other and are open approximately toward the axis of rotation of the cutting head.
