Abstract
An air intake screen is provided for deflecting foreign matter away from an air intake passageway of a lawnmower. The lawnmower includes an engine that draws air through the air intake passageway during the operation thereof. The air intake screen includes a central hub and a disc-shaped member projecting therefrom. The disc-shaped member terminates at an outer periphery and includes first and second sides. Apertures extend through the member for allowing for the flow of air therethrough. A deflection rib projects from the first side of a member to engage the debris carried by the air drawn towards the air intake passageway of the engine and deflects the debris away from the air intake screen.
