A replaceable mower blade for attachment to a mounting member operatively connected to a mower is provided. The blade includes a central portion having opposing side edges, a top surface, and a bottom surface. The blade also includes a tip portion extending from the central portion. The central portion includes at least one attachment mechanism for operatively connecting the blade to the mounting member.
1. A replaceable blade for attachment to a mounting member of a lawn mower, said blade comprising:
a central portion having an upper surface, a lower surface, opposing side edges, and an end extending between said side edges;
a tip portion extending from said central portion opposite said end; and
at least one attachment mechanism, wherein each of said at least one attachment mechanism is located on said central portion, wherein one of said at least one attachment mechanism is a plurality of locking apertures formed through said central portion, and wherein said plurality of locking apertures includes three locking apertures forming a pattern, and wherein a line extending between of any two of said three locking apertures is not parallel to a longitudinal axis or a lateral axis of said central portion.
2. The replaceable blade of claim 1 , wherein each of said plurality of locking apertures is formed as a keyhole aperture.
3. The replaceable blade of claim 1 , wherein another of said at least one attachment mechanism is an indexing aperture formed through said central portion, and wherein said indexing aperture is surrounded by said plurality of locking apertures.
4. The replaceable blade of claim 1 , wherein another of said at least one attachment mechanism is an indexing aperture formed through said central portion.
5. The replaceable blade of claim 1 , wherein another of said at least one attachment mechanism is a plurality of caps extending from said upper surface of said central portion.
6. The replacement blade of claim 1 , wherein said opposing side edges are curved.
7. The replacement blade of claim 6 , wherein said opposing side edges are curved upwardly relative to said upper surface.
8. A replaceable blade for attachment to a mounting member of a lawn mower, said blade comprising:
a central portion having an upper surface, a lower surface, and a thickness extending between said upper surface and said lower surface;
a tip portion extending from said central portion;
a first attachment mechanism positioned on said central portion, wherein said first attachment mechanism is formed at least one locking aperture formed through said thickness of said central portion, and wherein said at least one locking aperture is a plurality of locking apertures forming a pattern on said central portion, and wherein alignment of any two of said plurality of locking apertures is non-parallel relative to a longitudinal axis and a lateral axis of said central portion; and
a second attachment mechanism positioned on said central portion, wherein said first and second attachment mechanisms selectively connect said central portion to said mounting member.
9. The replaceable blade of claim 8 , wherein said second attachment mechanism includes a portion of a male-female connection.
10. The replaceable blade of claim 8 , wherein said at least one locking aperture is a plurality of locking apertures, and each of said plurality of locking apertures is formed as a keyhole aperture.
11. The replaceable blade of claim 8 , wherein said second attachment mechanism is formed as an indexing aperture formed through said thickness of said central portion.
