ABSTRACT:
A blade guard for rotary lawn mowers comprising a plurality of spaced apart elongated members which extend longitudinally in the intended direction of travel of the mower device. The space between the forward ends of the elongated members and the forward end of the mower cowling is open and free from obstructions to permit the grass to be sucked upwardly for cutting by the mower blade. The elongated members have varying lengths to define an effective area substantially the same as the area defined by the unsharpened center portion of the mower blade when rotating so that the sharpened ends of the blade extend outwardly beyond the effective area of the guard means. The guard means is hinged to the mower cowling to permit convenient cleaning of the mower. An ignition interlock means is also connected to the guard.
