ABSTRACT:
A novel blade and a rotary mower blade assembly involving use of the blade are described. The blade has (a) an extended inner end portion and (b) a bifurcated outer end portion comprising (i) a forward radially-extending outer segment carrying at least a portion of the cutting edge, and (ii) a rearward radially-extending outer segment spaced apart from said forward segment. The blade assembly involves a pair of spaced apart looped retaining bands affixed to a rotary blade support arm. One of these bands is secured to an intermediate portion of the blade support arm and the loop of this band is sized to slidably receive and securely encircle a rearward portion of the blade. The other band is secured to an outer portion of the blade support arm and the loop of this band is sized to receive and encircle the rearward bifurcated segment of the blade (i.e., the segment constituting the trailing edge of the blade). In this case however, the width of the segment encircled by the band is less than the width of the space within the loop thus leaving a gap therebetween. A keeper is provided which can be snugly fitted into this gap and thereby keep the blade secured to the support arm.
