A cutting blade overload protection device for a cutting mechanism of a harvester for leaf and stalk material, having a cutting blade pivotable about a cutting blade rotational axis and which is connected to a toggle lever mechanism. The toggle lever mechanism includes two coupled toggle levers pivotable about a toggle lever rotational axis and which move the cutting blade from an operating position to a resting position when a predefined force is exceeded. To protect the cutting blade better when contacting foreign objects, the device has a toggle lever mechanism which comprises a stop limit and a spring element, with the spring element and limit stop interacting such that when a predefined force is exceeded, the toggle lever rotational axis is moved past a dead center point, with the position of the toggle levers shifting from a first buckling position through a straight position into a second buckling position.
