I am going to blow a little steam. I do not think Gleaner is Going to respond though I admire your attempts. If it were so simple would they not have fixed it long ago. That combine works best in the dryest desert conditions possible. They don't sell any in High humity areas like Europe or Rice country. They are not spending much on research on the R series from what I hear. (Do they spend much on research periodIJ They just buy another company and milk it for all its worth.) The feeder house is maxed out. If the fixes work, they only work in certain conditions and do not increase capacity substancialy. I have made a lot of round bales between the two feeder chains. Nothing solves the problem like a wide feeder house with one chain. The answer from Agco is a Massey or Challenger. I have run one side by side a Gleaner and if you want feeding in tough conditions there is no comparison though the feeder chain can jump a tooth on it also. Not having enough research on it either in my opion. But plugging is not a problem. I am not saying the rest of the Massey concept is any better but the feeding sure is. On the R-Series they have been back and forth on big drums, little drums, extended drums, sped up feeder chains, false floors, abrasive resistance floors, thicker floors, stainless floors for front chain,then no stainless, one piece feeder slats, two piece feeder slats, clutch on rear feeder chain, no clutch on rear feeder chain, strippers on front feeder chains in and then out, same for back chain, little sprockets on rear feeder chain drive, then chromed little sprockets, then big sprockets, then chromed sprockets, then hardened shafts, then bigger shafts. It seems to me they just go in circles and are out of ideas except for a wider feeder house. Reliability is for another day.
