发明名称 Blade guard for rotary lawn mowers
摘要 A blade guard for rotary lawn mowers comprising a support means secured to the mower cowling and having a plurality of spaced apart elongated members secured thereto which extend longitudinally in the intended direction of travel of the mower device. A guard ring is mounted on the support and extends upwardly therefrom adapted to engage the unsharpened portion of the mower blade to prevent the elongated members from being struck by the blade upon the elongated members being deflected upwardly relative to the blade. The forward ends of the elongated members have spear-like points provided thereon which are positioned in openings formed in the forward skirt portion of the cowling. A bumper guard is secured to the cowling and is positioned over the forward ends of the spear-like points. The points comb and rake the lawn while it is being mowed with the grass hairpinning over the points to cause the same to be lifted so that the loose grass rides upward and rearward as the points move forwardly relative to the grass. The grass hairpinning over the points is fed into the tip circle of the rotating blade.
