An arrangement for cooling the engine of a harvesting vehicle includes a circular sieve or screen mounted for rotation about a fore-and-aft axis and through which air is drawn by a fan which discharges the air through a cooling device. A cleaner in the form of a brush includes a cylindrical bristle arrangement mounted for rotating about an axis arranged parallel to an inlet side of the sieve with the bristles projecting through sieve openings. Located on the outlet side of the sieve is a suction device that acts to carry away contaminants poked through the sieve by the bristles of the brush. A further embodiment of the invention includes a second suction device mounted adjacent the inlet side of the sieve in trailing relationship to the brush arrangement so as to be able to carry away contaminants loosened by the brush arrangement but still clinging to the inlet side of the sieve.
