Have the rotors outta my TR86 and am in need of some new concaves. Do the round bar work good soybeans too or would the regular ones work better. Mainly use it for soys but do occasionaly run corn when needed and a wee bit of barley each year. The barley doesn't really concern me since it is only 50 acres compared to the 800 acres of beans she eats. And what can I do to my rotors to make them better? Thanks for any help.
