Abstract
A forage conditioner for conditioning cut crop material from a forage harvester includes a fixed bottom fluted roller carried in end housings and a top fluted roller which is pivotally mounted on the housings by a linkage pivotal relative to the housing about an axis lying in a plane at right angles to the roller axes so that the top roller is liftable from crushing position against the bias of a spring extending along the top roller. Rotation of the bottom roller is transferred to the top roller through a gear train which includes two idler gears each mounted on a respective arm with the arms constrained to move symmetrically relative to the rollers by intermeshing teeth on the arms so as to control the angular timing of the rollers to ensure accurate intermeshing of the flutes.
