Patent ID: 6925787

Claim:
A rotary blade blocker secured to a perimeter edge of a deck of a rotary-type mower to prevent inadvertent firing of an internal combustion engine of the mower during rotary blade removal and replacement or during manual debris removal from within a mower deck of the mower, consisting of: an L-shaped bracket having a threaded clamping member dependently attached to, and adjustably moveable with respect to an inner facing surface of, one leg of said bracket; a blocking member connected on an inner surface of a second leg of said bracket in spaced limitedly adjustable relation and forming a gap of adjustable width with respect to a proximal end of said clamping member extending from the inner facing surface of said one leg, said gap adjustably sized and received over a lower edge of the deck and secured by tightening of said clamping member against an outer surface of the edge of the deck, a lateral surface of said blocking member making non-entrapping contact with, and preventing rotation of the rotary blade in one direction in an amount sufficient to cause inadvertent firing of the engine during blade replacement or debris removal from within the deck.
