I live in an area where edible beans are grown. Have never heard of any problems with rethresher so I cant say for sure, however, I know for certain that you need a cylinder slow down kit on the machine to run cylinder slow enough or you will get a lot of grain damage from too much cylinder speed. edible beans are tough on a machine-- lot of dirt-- have a neighbor that had run so much dirt though a 860 combining edible beans that the dirt was packed so hard in the unloading auger the motor couldnt turn the auger. Anyway I know for sure you will need a cylinder speed slow down kit for sure, Good luck.
