Zusammenfassung:	The invention relates to an air-cooling system for a drive engine of an automotive agricultural machine, in particular a field chopper. It is a goal of this invention to provide a forced-air cooling system with considerable cooling capacity and a good cleaning effect for screens and the engine compartment. This object is attained by providing a cooling system where the warm air is blown upwardly and selectively to one side, a reversal of the cooling-air stream for cleaning the screens being possible, and a forced-air ventilating of the engine compartment being assured. The basis of the invention is that an air compartment is provided with two fans mounted between a pair of radiators each behind a respective screen. An air-deflector plate is so arranged in the air compartment that it is possible to alternate the fans between radiators so that the cooling-air stream can pass in either direction through each of the radiators and screens. One fan meanwhile blows cooling air into the engine compartment, which air escapes upwardly through openings in the upper machine wall.
