Abstract: A lawn mower assembly having a leaf blowing blade includes a blade assembly for converting a lawnmower into a leaf blower. The blade assembly includes a substantially planar disc member that includes an outer perimeter edge. A connection portion extends outwardly from the disc member. The connection portion is designed for coupling to a blade attachment portion of the lawnmower such that the disc member is rotatable by the lawnmower. A plurality of spaced elongated blades extends downwardly from a lower surface of the disc member. The disc member is coupled to the lawnmower with the blades extending radially outward from the connection portion.
