Abstract
An elongated air intake screen is provided for vehicles such as commercial mowers that operate in conditions having substantial airborne foreign materials that tend to clog the screen. The exterior surface of the screen is provided with intake openings throughout its 360 degree surface to draw air over a substantial area. It is located at the upper edge of the vehicle to separate it from the cutting decks and area where airborne grasses and similar foreign materials are encountered. Air drawn into the screen is used to cool the engine and hydraulic fluid heat exchangers and provide for engine combustion needs.
