Abstract: A transport system for a crop header includes a first and a second wheel arrangement on the header frame adjacent a respective ends for acting as a stabilizer when the header is in the operating position and movable to a transport position for transporting the header when removed from the vehicle in a transport direction generally longitudinal of the header frame and at a right angle to the working direction with each being mounted on the header frame for rotation of a rolling direction of the first wheel arrangement between the working position and the transport position, in which the rolling direction is along the transport direction. Each of the wheel arrangements includes two parallel wheels coupled together.

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.
