Good day sir. I noticed a post that you had talking about an 873 adapter that you used in peas. We have a 25' 972 macdon head with the 873 adapter. When we are harvesting peas, we keep having problems with the crop pluging in the center canvas area. I'm wondering how you had the drum set on your adapter and any tricks that you have come up with on making this thing feed peas. We have ours set all the way up and back. I would appreciate any advice at this point. Thank you.
