Hey, all. We have a '00 9650STS that we have been using entirely for harvesting sorghum. We're now looking into planting some soybeans. What should I be doing about the concaves? We run JD large wire currently. Just wanting to know what some of you do that harvest different crops. Don't know whether I should get the round bar set, or maybe just one or two, and mix and match. Aftermarkets? Genuine JD? Any insight would be greatly appreciated.
