In Reply to: HELP - Threshing Problems - on new 8780 posted by Kidd Farms on August 23, 2000 at 13:35:32:

We run a 8560 and have same problem.The biggest help was on top of the concaves just above your 3-blanks is a bolted on grate.(ONLY TO BE USED IN CORN)A solid small grain plate gets bolted in it's place.Also a slower rotor speed and tighter concave does a better job of threashing.Don't give up on a great machine you can alway's go back to bigger headaches.
