Mower blade mounting member with replaceable blades

A mower blade assembly attachable to a rotatable spindle, motor, or engine crankshaft, said mower blade assembly comprising:

• a mounting member having a central bore and a plurality of ends extending from said central bore, wherein each end includes an indexing aperture formed therethrough, and wherein said mounting member includes a plurality of caps extending perpendicularly and positioned about each of said indexing apertures, wherein each end of said mounting member is channel-shaped;
• a locking mechanism operatively connected to said mounting member, said locking mechanism including a base and a plurality of arms extending from said base, wherein each arm includes a pin extending therefrom;
• and
• a plurality of cutting blades, each of said plurality of cutting blades being removably attachable to one of said plurality of ends of said mounting member, wherein each cutting blade includes an indexing aperture formed therethrough, and each cutting blade including a plurality of keyhole apertures for receiving said caps of said mounting member;
• wherein each pin of said locking mechanism is biased into engagement with said indexing aperture formed in said mounting member and said indexing aperture formed in said cutting blade for positively positioning said cutting blade to said mounting member, and wherein engagement of said caps of said mounting member with said keyhole apertures of each of said at least two cutting blades provides for toolless attachment and removal of said at least two cutting blades to said mounting member.
