ABSTRACT:
A holder for releasably securing an elongated bar, e.g. a cutting blade, to a drive-means comprises: (a) a holder body adapted to be connected to the drive means and having a substantially flat outer face for guiding and holding the bar; (b) an engaging means biased outwardly from the flat outer face to engage a hole in the bar; and (c) a wall spaced apart from and opposing the flat outer face and connected thereto by a spacing means to form a guiding recess for the bar formed along a longitudinal side edge of the flat outer face and having openings at both longitudinal ends of that face. An elongated cutting blade can be adapted to fit in this holder and the blade-holder combination is especially useful on rotary lawn mowers. The blade is quickly and easily released from the holder for sharpening or replacement.
