Abstract

Curved shapes applicable for making lawnmower cleaning tools for removing debris in a cutting chamber of a lawnmower have been developed. Using these conformally shaped curves improves the performance of mechanically based lawnmower cleaning tools dramatically. The conformal shapes closely conform to the shape of structures found in the cutting chamber of lawnmowers. The shape is designed such that in use, curved portions of tools based on them usually pass within about 1/4 inch of the surfaces being cleaned even if the curves touch the cutting chamber surfaces at only one point. Straight portions can be adjacent the curved portions of the curves for cleaning the vertical portions such as a mower skirt around the cutting chamber. The curves can also comprise smaller features designed for cleaning hard to reach areas of the lawnmower cutting chamber.
