A ventilation device of an agricultural vehicle such as a combine, forage harvester or tractor having an engine (10) and a cooling device (12) for cooling the engi ne (10) and/or additional parts to be cooled that are in a heat conducting relationship. Th e ventilation device comprises a fan (20) a fan drive (18) and a control system (26) connected to the fan drive (18) to regulate the feeding rate of the fan (20). The control system (26) is arranged to control the fan drive (18) in the most energy-efficient way while making allowance for t he amount of ambient air required by the cooling device (12) and the drive power requirements of the fan (20) using a flat logic (fuzzy control).
