Abstract: A safety blade for a rotary mower along with a rotary mower is provided in which the rotary mower has a blade housing with an annular band mounted for rotation therein. The annular band has teeth encircling the edge and is connected to the drive shaft by supporting cross members. The annular band may extend vertically when attached to a mower, or may be angled inward towards the center; and may have a fixed or removable annular blade portion. The cross support members may have features for removing grass, and the mower housing may have an opening for the ejection of grass from the sides or the top of the housing.
