i am setting up a 9770sts with a 635f head. always put in 3 small wire concaves. harvesting 15% winter wheat, windrowing the straw. iv had an issue with capacity with soo much material coming through the machine, that i have to slow down to 2.5mph otherwise i am losing grain over the rotor. i am just wondering what concave setup guys use to get more capacity when windrowing straw. have tried adjusting rotor speed and concaves,but this does not seem to do much, combine is only 1year old and well maintain by the dealer here. some thoughts would be appreciated// thanks

are you cleaning it up ok? i would maybe try pullin everyother wire out on the back concave and maybe even some on the middle. we pull every other one out on all of them for milo and have no trouble with capacity so if your wheats thrashing good i would think that might help? just a suggestion

setup the 9770sts with two small wires and the last small wire i pulled every other wire- works alot better-reduced the rotor loss quit abit. also have a 2010 9870, the last two small wires, i pulled every other wire- seems even better when it comes to rotor loss. running 16% wheat ranging anywhere from 60-110 bushels

We are running all round bars but have inserts on the front one. This is on soft white and soft red winter wheat with around a 1% dockage and 15.5 moisture
