I'd say you're at capacity on that elevator assuming you're swallowing 6-30's. My 1680 would bog in that kind of corn at those speeds and it had a larger elevator leg. The 2188 now has a two speed sprocket on the clean grain for heavy corn. Don't know if it can be retroed to older machines and if so what the ramifications might be. As to changing to the bubble up, I'd say no since those are on combines with larger legs, but that's only a guess.
