Extensive field testing proved that a deeper flighted auger sitting in a trough will feed better than a smaller one sitting on a flat pan. It is with this theory in mind the RX shaker pan machine was discontinued in favor of the direct feeding RVS header, this allowed the use of a common main frame with the CVS.
The Variable speed drive system was also introduced from the CVS model which allowed the operator to make rotor speed adjustments from the cab.
The RVS range features more stainless steel than on previous rice special models. The crop deflector, top hood and floor are stainless and the auger flighting and retractable auger fingers are made from hardened steel.
