<p>@ The subject invention is a lawn mower blade hub member (200) adapted for interconnecting a plurality of flexible blades (600), all affixed and disposed in a radial fashion from the centrally disposed hub member (200), which hub member (200) is then mounted for concentric rotation on the lawn mower engine drive shaft (100); and wherein each such blade (600) mounted to the hub member (200) is comprised of a flexible, non-rigid, material, The hub member (200) is a circular, plate-like member which has a plurality of insert openings (265) which are adapted to receive and securely hold the radially inner ends of the respective flexible blade member (600). Disposed laterally adjacent to and just radially outwardly of the respective insert openings (265) are vertically extending bosses (360), which bosses (360) are disposed between the respective insert openings (265), thereby forming between adjacent bosses (360) a channel area to securely hold a portion of the radially inner end of the flexible blade member (600) in a radially out wardly rigid position.</p> |
