Abstract
A forage harvester is provided with a chopping arrangement and a reworking device downstream from the chopping arrangement. The reworking device having two rolls between which the harvested crop chopped by the chopping mechanism can be passed through and whose spacing and/or compressive force is adjustable by a unit that is actuated by an external force and is connected with a control device. The control device is acted upon by information with regard to the cut length of the chopping arrangement and directs the unit as a function of the cut length.
