What licence is required to drive a special agricultural vehicle that can exceed 45 km/h?

The class B driving licence authorises the driving of self-propelled special agricultural vehicles or combinations thereof, whose maximum authorised mass or dimensions exceed the limits established for ordinary vehicles and which can exceed 45 km/h. The agricultural vehicle driving licence, on the other hand, authorises the driving of agricultural vehicles that do not exceed the limits of ordinary vehicles and do not exceed 45 km/h.
