A forage harvester having a rotatable cutter head coacting with a shear bar is provided with a grinding wheel which is power driven and adapted to be moved longitudinally along transversely extending guide means adjacent the circumferential outline of the cutting edges of the knives of the cutter head while the grinding wheel is rotating. When the guide means is in one position, the grinding wheel is positioned to sharpen the cutting edges of the knives and, when one end of the guide means is shifted to a second position, the grinding wheel will be positioned to grind bevelled surfaces of uniform depth and width along said knives rearwardly of the newly sharpened cutting edges thereof.
