The blade has a slot, wherein the slot is designed to receive a blade-holding element of the mowing unit such that the blade can rotate about the blade-holding element and move in translation relative to the blade-holding element for one cutting position of the blade defined by one end of the slot having one cutting orientation of the blade and another cutting position of the blade defined by another end of the slot having another cutting orientation of the blade. A line segment delimited by the ends of the slot does run non-parallel to sides of the parallelogram, and the parallelogram has an obtuse internal angle.
