Quick change blade for a rotating blade assembly of a mower implement

A rotating blade assembly for a mower implement, the rotating blade assembly comprising:

• a disc defining a rotation axis and extending radially outward away from the rotation axis to a radially outer disc edge, wherein the disc defines a mounting aperture proximate the radially outer disc edge;
• a spring plate coupled to the disc proximate the rotation axis and extending radially outward away from the rotation axis to a radially outer plate edge, wherein the spring plate defines a pocket aligned with the mounting aperture;
• a blade having a body defining a pin aperture and positioned between the disc and the spring plate;
• a retaining pin including a shaft portion extending through the pin aperture of the blade, wherein the retaining pin is engaged with the mounting aperture of the disc and the pocket of the spring plate, wherein the shaft portion of the retaining pin defines a shaft diameter;
• wherein the spring plate is configured to exhibit a bias force at the pocket in a direction toward the disc to capture the blade between the disc and the spring plate;
• wherein the body of the blade includes a radially inner edge relative to the rotation axis, with the body defining a tail length between the pin aperture and the radial inner edge;
• and
• wherein the tail length is equal to or greater than seventy five percent (75%) of the shaft diameter of the shaft portion of the retaining pin.
