ABSTRACT:
A cutting and mulching blade assembly for a rotary lawn mower characterized by being adapted for fine mulching of even long grass and blowing of the grass cuttings away from the internal surface of the shroud housing of the mower back on the lawn among the remaining grass, such as to obviate the need for raking. The self-cleaning feature also allows making the shroud housing without lateral outlets for more safety. This cutting and mulching blade assembly comprises a mulching blade made of essentially the same blank as a conventional lawn mower blade and operatively secured to such cutting blade by a hub member for bodily rotation together and with the mulching blade formed to blow the grass cuttings inward and downward back on the lawn.
