We are in the proccess of putting a 2002 R-62 into grass seed. This will be the first gleaner in grass in our area. I haved already blanked the bottom half of concave and blanked the seperator concave also. We have the small seeds kit installed. We are contemplating adding more helical bars over blanked seperator concave and on discharge and are also thinking of blocking off cage. Has anyone tried this or have other suggestions it would be appreciated. We will be running in many grass verieties such as needle grass, bluegrass, and others I don'tnknow yet.
