摘要： A lawn mower blade having a thickness of approximately 0.075 inches comprises a main body, an elevational profile, and end portions equidistant from the center of the blade. The elevational profile consists of a raised portion that reaches a height at the plateau portion at the center of the blade. The elevational profile increases at an angle &agr; as the end portions approach the plateau. Each of the first and second end portions has a cutting edge portion. The height to blade thickness ratio is at least two-to-one. Further, since the mower blade is generally not heat treated, ribbing is added to the mower blade to provide strength.
