Though the left hand bandaid is a college educated engineers idea to fix the issue, it is a component mismatch and setup issue at its core. I no longer have the plugging issue and I dont run those flaps.

 Here's a pic of a 2388 with the reverse flighting on the left auger and the.........multimilliondollarbandaid.

 I wish some of the xx10 series machine owners, especially those here in grass seed country would logon and post their experiences on the issue...............those machines dont have augers to put bandaids on and fling grain up.........to........................clean the..........................cage.
