I have an 8780, it has the 6 rub bars and one set of knifes.I use narrow wire concave with two concave blanks up front.Make sure you check and ajust concaves like the book says. I run roter speed at about 850 900 air at 760 800. I hope you have air foil chaffer.This machine runs the best when it is FUll" See if you have the new stile beater Massey says its a big improvement we'll see.In 80 + wheat I can fill the tank in about 12 min. on average. let me know how it runs. good luck onion farmer ps I have updated mine with constant roter and beater
