NW Washington | If you have to deal with tough conditions like you describe there are a few things you can do to help the situation. A CaseIH rep told me years ago the number one problem they had with new operators is that they open the concaves when they should be closing them. The rotor has to have a grip on the MOG to auger it through the combine and out the back or else you get roping and banging as the material goes under the rotor or rolls up in a rope. So try closing the concaves if it starts grumbling, don't open them. The situation is not like a cylinder that just had to pass it through once and push it back to the walkers.
Also, what is the condition of your rotor rub bars, concaves and transport vanes in the cage? Things get worst when these are not up to par.
A CIH specialty rotor is designed to handle tough wet material better than the standard rotor, stuff like edible bean, green stem beans and rice.
The new spiral fronts that replace the elephant ears will help this problem too. They are available from several aftermarket combine parts suppliers. The new improved AFX rotors have a spiral front and different rub bar arrangement. "Disrupters" can be added to the separator grates to break up the tough wads and ropes and make them process easier. And Loewen makes a spring loaded concave that will deflect if a big slug hits it.
There are even some aftermarket modified rotors that claim to perform better in various situations. | |

How much abuse can a rotary IHcombine take (rotor)?
