Zusammenfassung:	A blade for a lawn mower includes a blade body, a longitudinal axis, a center opening, a first aperture, and a second aperture. The blade body has a first end and a second end opposite the first end. The longitudinal axis extends centrally along the blade body and through the first and second ends. The center opening is defined in the blade body and receives a drive shaft. The first aperture is defined in the blade body between the center opening and the first end. The first aperture receives a first projection. The second aperture is defined in the blade body between the center opening and the second end. The second aperture receives a second projection. The first aperture has a different shape than the second aperture. A centroid of each of the center opening, the first aperture, and the second aperture is substantially aligned with the longitudinal axis.
