Claim:
1. An agricultural baler comprising a flywheel connected via a cardan coupling to a connector that is provided to be connected to a PTO of a tractor, so that the flywheel can be driven by the PTO; and the cardan coupling comprising a torque-limiter adapted for at least partially disengaging the flywheel from the PTO when a predetermined torque is exceeded, the cardan coupling further comprises a transmission that is switchable between a startup state and a running state, in the startup state the transmission is configured to only partially transmit rotational movement of the PTO to the flywheel while in the running state the transmission is configured to fully transmit rotational movement of the PTO to the flywheel; wherein the transmission is formed as a gearbox and in the running state, the gearbox transmits the rotation from PTO to the flywheel in a 1 to 1 ratio while in the startup state, the gearbox transmits the rotation from PTO to the flywheel in a N to 1 ratio, whereby N is larger than 1.
