ABSTRACT:
A lawnmower blade which is characterized by an elongated, flat blade bar having a slight twist and fitted with a blower element at each end, along with pivotally or rotatably-mounted cutter discs. Each blower element includes a base plate secured to the blade bar and terminating in an extending blower top plate having top plate serrations on the end thereof. In a first preferred embodiment a perforated cutter disc is secured to each end of the blade bar beneath the blower element by means of a shoulder bolt which extends through one of six perforations to facilitate pivotally and eccentrically mounting the perforated cutter discs to the blade bar. In a second preferred embodiment a two-piece cutter disc is rotatably mounted on each end of the blade bar through an enlarged center opening. The perforated cutter discs and the two-piece cutter discs are provided with double-edged blade teeth to facilitate reversible mounting of the perforated cutter discs and the two-piece cutter discs on the ends of the blade bar.
