ABSTRACT:
A mower suitable for cutting high grass, brush, and like growth. The mower has a plurality primary cutting elements disposed ahead of a secondary cutting element. The primary cutting elements is that which first contacts growth, cutting this growth to a predetermined height. The secondary cutting element follows the primary cutting element, contacting the cut growth and cutting the same to a final, predetermined height less than that obtained by the first cut. The primary cutting elements are preferably unencumbered by a hood or guard, but preferably are partially encircled or surrounded at the front and sides by a bumper. The bumper prevents the mower from attempting to run over or cut rigid, immovable objects, such as trees, curbs, large stones, and the like. The primary and secondary cutting elements may be a singular element or plural elements arranged abreast of one another. The cutting elements may be rigid blades or flexible members, such as stranded metal, synthetic resin cords, or chains. The invention may comprise a mower incorporating the novel principles, or may be practiced by adding appropriate components to a pre-existing, conventional mower.
