Abstract:
A mower blade assembly attaches to a rotatable spindle and includes a mounting plate which defines a first pin aperture. The mounting plate and a retaining plate are attached to the rotatable spindle. The retaining plate defines a second pin aperture. A movable pin plate comprises a pin. A blade is selectively attachable to the mounting plate. The blade defines a retaining plate aperture and a third pin aperture. A biasing member urges the movable pin plate from a disengaged position to an engaged position. The pin is engageable with the pin apertures for mounting and retaining the cutting blade to the mounting plate. The blade is attached by moving the blade over the retaining plate aperture, urging the movable pin plate to the disengaged position, rotating the blade, and releasing the movable pin plate. Another embodiment includes a force finger.

Claim (Index 45):
A blade for a lawn maintenance device comprising:\n opposed end edges and opposed side edges, the blade adapted for mounting onto a lawn maintenance device for rotation about a center axis extended transverse to the blade, the blade having a blade major axis; the blade defines a central aperture located on the center axis; the blade defines a pin aperture positioned a distance from the center axis and a distance from the blade major axis; and the blade defines a force finger aperture positioned a distance from the center axis and a distance away from the pin aperture, wherein the pin aperture is located on a pin line that is not parallel to the blade major axis and the pin line passes through the center axis, wherein the force finger aperture is located on a finger line that is not parallel to the blade major axis and the finger line passes through the center axis and is radially offset from the pin line.
