Agricultural baler and method of protecting such baler from overload damage

An agricultural baler comprising:

• a flywheel;
• and
• a drivetrain for coupling the flywheel to a connector that is arranged to be connected to a power take-off (PTO) of a tractor, the baler including a decoupling mechanism for decoupling the flywheel from the connector in case of an overload, the decoupling mechanism comprising:
• a controllable member positioned on the drivetrain between the flywheel and connector that is moveable between an engaged state in which the flywheel is coupled to the connector and a disengaged state in which the flywheel is decoupled from the connector;
• a detector for detecting the overload, the detector is configured to provide an overload signal to the controllable member triggering the controllable member into the disengaged state;
• and
• a braking mechanism in direct engagement with the flywheel that is switchable between a non-braked state and a braked state,
• wherein in the non-braked state the flywheel is free to rotate with the connector,
• wherein in the braked state the braking mechanism is configured to halt the flywheel or to hold the flywheel in a fixed position, and
• wherein the detector is further configured to provide the overload signal to the braking mechanism after the controllable member is triggered into the disengaged state so as to switch the braking mechanism to the braked state.
