Abstract
Abstract A kit arrangement includes an elongate handle, including a first and second section angularly offset relative to one another to enhance access to an interior surface of a lawn mower surface, with a scraping head mounted to the handle, incuding a chisel and serrated scraping edge mounted to a leg of the head spaced from and orthogonally oriented relative thereto. A honing and wire brush are mounted to the head to enhance its effectiveness in a cleaning and sharpening operation relative to a lawn mower.
