Combines 8570 and green stem soybeans

Tighten up the concaves and see what happens. The rotor has to keep a grip on things to get them out the backend. If it slips you get roping, rumbling or worse.

Are the trailing edges of the teeth on the rotor elements directly behind the auger in good shapeIJ If they aren't reasonably square cornered, vines will bunch before they're fed back to the rotor. If in doubt, reverse them if you haven't already.

just a couple of suggestions, check out your 3 elements

We had the same problem with our 8560. We rebuilt the rotor with the exception of the auger tip. Our machine had 1600 hours on it when we rebuilt it. Then we had back feeding in the feeder house. Our dealer said it was either the auger tip on the rotor or our beater was bad. We tried the cheaper route since the hard surface was still pretty thick on the auger. Installed a new beater (the old style) and it now has great capacity in green stems and the rotor overload light doesn't come on until night when everything is getting wet.

Thank you all for your advice. All beater_rotor_concave components are in top shape. Tightening the concave helps, but still had problems. Yesterday I think we discovered our problem. While running, the rotor motor literally blew apart! Could that motor have been getting weak, giving wimpy torqueIJ Our dealer brought out a new 8780XP for us to demo. One word - AMAZING. I am not a speed demon, but I purposely pushed this thing to find it's limitations. I could run 50 bpa soybeans, with green stems in spots, (20' header)at 6+ mph and not phase it. I may have to sell one of my kids so I can trade.
