I was wondering if any of you out there have tried any brands of aftermarket concaves? I am interested in how a Kuchar concave would work on a nonbullet rotor 9760sts in corn and milo. I don't belive that the round bar concaves are doing a complete job of thresing or definatly seperating. Thanks for any imput!

Used Loewen (now A&I) concaves in STS & CTS for years - chalk & cheese compared to standard JD.

Any type of large wire concave would help your threshing problem. PF Parts makes a solid concave and they come in 6 instead of 3 so R&R is much easier.

I would highly recommend kuchar concaves, the difference is night and day.
plus if you don't like them he will give you your money back.

what crops do you harvest 9570sts? How much of a gain in capacity did you see compared to you old john deere concaves?

I grow corn and soybeans, I would say 30% more capacity maybe more in certain conditions. plus alot better sample.
personally I wouldn't run a combine without his kit. just my opinion

I am assuming you have the smooth elements, if so, I would defiantly go with his rotor bars and concaves first and then latter you could get the feed accelerator.
I don't want you to think his stuff will totally stop the rotor loss in a high trash situation because it wont, but it is allot better.

They priced the concaves at $3,960 where John Deere round bars would be around $2500. Do you think most of your gain in capacity came from the concaves or the rotor elements? Were i am getting at is that we can't afford the whole converson and our rotor isnt' worn out. So I was just thinking of switching just the concaves.
