<p>A forage harvester has a cylinder type cutterhead and a plurality of feed rolls that feed crop material radially into the cutterhead over a shear bar normally positioned adjacent to the cutterhead in registry therewith. The shear bar is mounted for resilient yieldable deflection when the cutterhead strikes a foreign object to a deflected position wherein it permits the tangential expulsion of the foreign object at the shear bar.</p> |
