摘要
A cutting device is adapted for cooperating with a tined rotor that receives crop delivered by a pick-up. A selector mechanism is provided for selecting the number of effective knives for reducing the crop conveyed across the knife bed. This selector includes a selector rotor rotatably mounted to a pivoted lever arrangement which may be raised to a non-use position when all of the knives are to be used for crop reduction. The selector rotor includes four rows of different arrangements of selector tabs spaced equally about the axis of the rotor. Lowering the lever places the rotor in a working location where a selected one of the four different rows of selector tabs is positioned for blocking a desired number of safety trip devices, which are associated one each with each cutter knife, in a retracted position where it is prevented from interacting with its associated knife, whereby the knife remains in a non-working position.
