A combine harvester has a chopping mechanism and a spreading mechanism. The spreading mechanism is disposed downstream of the chopping mechanism, mechanically driven by a drive train and includes at least two rotors. The drive train of the spreading mechanism has a belt drive engageable by a clutch and configured to drive a first transmission stage via an output shaft, at least one second transmission stage drivably connected to the first transmission stage by a shaft and a braking device. The first and second transmission stages each have an output shaft for driving one or each of the rotors.
