Abstract
A self-propelled harvesting machine includes a drive engine, a cooler and a cooling fan preceded by a cooling-air cleaning device incorporating a filter for retaining dirt particles in the drawn-in cooling-air and also including a suction device for removing said dirt particles, and the cooling-air cleaning device being driven by means of an engageable drive means. One aspect is that the drive means is engaged in dependence on a value measured by sensors. The suction housing and/or the baffle plate is rotatable under gravity or by being motor driven, when the suction device is switched off, into a position covering a region associated with the lower part of the filter device.
