Forage harvester cutterhead and method of sharpening |
摘要 |
A forage harvester having a cutterhead with underbeveled knives thereon is disclosed. In a preferred embodiment, each knife has a lateral cross sectional configuration closely resembling an isosceles trapezoid with the initial cutting edges formed by the sides and the longer base thereof. Sharpening of the knife results in the formation of a new cutting edge on the side which is closer to the shorter base than the previous cutting edge. The method of performing the sharpening operation is also disclosed.
