The customers that I have also run 2 cover plates for beans when you have ever other wire is pulled in all the concaves. Hope this helps. Trial & error. Keep us posted. Hows harvest going in your area?
I'm in north east ohio. Early beans are ready to come off but still a week or two away on the rest of our beans. If I can get out of work I will run today. I left 2 plates in to start with and all the wires in, I'll see what happens.
If all wire's are still in around here we don't use any cover plates. depends on differ situations. We've been see'ing alittle of everything being harvested in my area. Yields very depending on rain,hail & the LOVELY fuel price for irrg. Don't miss that when I farmed.
I took out all the cover plates and I'm not haveing any problems. Rebuilding the concaves and grates have turned my combine into another machine, last year the fastest I could go was 3.5 mph this year 4 to 4.5. Thanks for the replys.
