Abstract
A rotary lawn mower blade mounted on a blade carrier by diametrically spaced bolts is further retained against release from the drive shaft by a retainer fixed on the drive shaft and having a shank extending through a central opening in the blade and having an enlarged head to obstruct separation of the blade from the retainer. Preferably, the blade opening is larger than the shank and the retainer head is in the form of a transverse bar, narrower than such opening, so that the blade can be removed by manipulation in one direction to an eccentric position, then tilted to disengage it from one end of the bar, and then moved in the opposite direction to disengage it from the other end of the bar.
