For existing chaff spreaders, CanAGRO GmbH added in 2012 an auger screw with 400 mm and a cross-lying feed screw that absorbs bulk goods pushed backwards nearly entirely and pushes them to the centrally fitted auger screw. To adjust the output, a hydraulically operational control pusher is fitted in front of the cross-screw.
The drive of the cross-screw is provided by means of a hydraulic engine, the drive of the auger screw via drives through the drive train.
