I run a R-72 in edible beans and it does a wonderful job. Hardened helical bars are a must (black iron ones won't last a day in tough beans) and run cylinder at 4 to 8 depending on chute loss and cracks, @ 250 to 300 rpms, top seive 5_8" and bottom at 3_8 has worked well in pintos and Great Northerns. Run the fan choke at 6 to 7 (as long as they don't get blown out) helps with the dirt. As far as reverse bars, we are not using any this year and are getting along good. Most time we use 2 to 3 reverse bars. The clean elevator slow down kit is nice to save on cracks.
