A binding system for an agricultural harvesting machine may include a binding mechanism securing binding material around a crop package and a delivery device coupled to the binding system and including an overload relief component. The delivery device wraps binding material around a portion of the crop package and provides binding material to the binding mechanism. The overload relief component releases the delivery device from the binding system upon encountering a predetermined overload condition.
