Abstract
A forage harvester having a rotatable cutter head co-acting with a shear bar is provided with means to rotate the cutter head stepwise for inspection of the knives of the cutter head without manually engaging the same. The means for advancing the cutter head also provide tension applied against the knives of the cutter head incident to the same being ground by a rotatable grinding wheel to re-bevel the surfaces of the knives adjacent the cutting edges thereof for purposes of producing effective operating engagement of said grinding wheel with said knives during such re-bevelling of the same.
