Abstract
A forage harvester cutterhead of the type having a rotatable member carrying circumferentially spaced cutting knives. Each knife is beat such that a leading cutting portion is directed radially inwardly of its trailing portion and ahead of its knife support so as to provide better cutting power efficiency and more clearance for its mounting means. The bent knife configuration allows a thinner knife edge to be used and provides improved quality and uniformity in cut crop material. The thinner knife cuts through mat of material with less force and less disturbance to uncut material resulting in fewer long particles pulled from mat and much fewer long cob particles. Corn cobs are not dislodged from mat due to lower cutting force and hence are sliced up neatly.
