Abstract:
1. A method of removing debris from an operating surface, the method comprising the steps of: providing a debris removal tool, comprising a head unit having (i) a base plate, (ii) at least one cutting tooth pivotably coupled with and extending outwardly from a lower surface of said base plate, (iii) a drive unit operatively coupled with said base plate in a manner that permits said drive unit to selectively rotate said base plate about an axis extending generally normal to said base plate, and (iv) a flex plate that is operatively coupled with said base plate and said drive unit such that the axis on which said base plate rotates is permitted to swivel with respect to said drive unit; positioning said debris removal tool closely adjacent the operating surface such that the at least one cutting tooth may engage debris on the operating surface; actuating said drive unit so that said base plate begins rotating; and moving said debris removal tool closely adjacent the operating surface so that, as said base plate and said cutting tooth rotate, (i) the at least one cutting tooth engages the debris, and (ii) the at least one cutting tooth pivots with respect to said base plate and removes at least a portion of the debris from the operating surface.
