ABSTRACT:
A rotary cutter comprises a first knife located on a knife shaft having a longitudinal axis, a second knife spaced from the first knife by an adjustable cutting gap, a control unit including a drive for turning at least one of the first knife or the second knife, and an adjusting mechanism for moving at least one of the first knife or the second knife in the direction of the longitudinal axis to adjust the cutting gap. The adjusting mechanism comprises a first signal transmitter for detecting a zero position of the first and second knives; a second signal transmitter for detecting the cutting position of the first and second knives; and an adjustment drive coupled to the first and second signal transmitters for movement of at least one of the first or second knives from the zero position to the cutting position.
