A free-cutting mowing machine, comprising a trailing beam, a mowing beam, swingably carried on the trailing beam, a plurality of cutter discs arranged next to one another rotatably about vertical axes on the mowing beam, a guarding means operatively carried swingably on the trailing beam and extending over the knife discs, guiding means hingedly operatively connecting the guarding means cooperatively together with the mowing beam such that the guarding means automatically is close to the knife discs during swinging up of the mowing beam in a transportation position, the guarding means being maintained freely projecting without supporting on the trailing beam, the trailing beam including a part forming a carrier for the guarding means, and the part, the mowing beam, the guarding means and the guiding means cooperatively connected forming a four-link connecting rod drive including individual links so designed that when in an operating position of the mowing machine, the guarding means is in a position substantially parallel to the mowing beam, and when in the transportation position, the guarding means is in an inclined position toward the end of the upwardly swung mowing beam.
