look on the home page to this site. Then click on the "cover plates" link. He has them up to the 2388's for sure. They go on the OUTSIDE of your existing concaves, normally covering half the concave area at the front of the rotor. What this does is makes the front of the rotor a threshing area, and the rest of the rotor a seperating area. It prevents unthreshed material from falling through the concaves prematurely, which I could sure see with a stripper head in rice. Or disease damaged soybeans. I'd guess you were on the right track with the Shelbourn Reynolds blanks. But you just don't need a blank, you need threshing area. And, I'd also guess that the corn retarders probably just put even more unthreshed crop out on the shoe, and contributed to the rotor pulling way harder than it needed to. If you can't get the crop threshed, you can't seperate it. What we do is run all large wire concaves with every other wire pulled all the time. This works well for corn. Obviously, it ain't gonna work to well for wheat, or rye, or soybeans, or milo, or probably rice.(I'll make a disclaimer here that I have no direct experience with rice). We have harvested a lot of low yielding tough threshing beans the last 2 out of 3 years due to drought. We were having problems with whole pods in the tank in beans and whole pods going out the back. This would be in 11 bu beans so it was very frustrating. Put in disrupters, and they helped the loss out the back, but really didn't solve the problem. Cover plates fixed er up. It's now easy to eliminate unthreshed pods and not crack the heck out of beans. My custom customers who grow seed beans like the job as well. Also, rye, is a tough strawed(we don't swath) relatively low yield, hard to thresh crop. I could just never get as clean a sample as I wanted. I can get good samples now, and use less HP doing it because of better threshing and less returns. Returns can be a big issue in high yielding milo, as well. Before I put in cover plates I really struggled to do a good job cleaning milo. It still isn't a breeze, but I can do a good job, and don't have to move at a crawl to keep from plugging the returns. We harvested a field of Milo this year that avg 155 bu at about 3.0 MPH with an old 1480. With an axial flow, you really don't have much of a second chance to thresh the crop, and I'd say this is still pretty much true with the 8010, due to the relatively small size of the rethresher area. The 8010 has MUCH more concave and grate area than a 2388, so what worked well with the 88's might not work so well with the 8010. The crop sees a lot more open space than threshing area, so too much unthreshed grain gets through, especially in short crop, or tough threshing conditions. Now, I hope I don't sound like a know it all, because I sure have a lot to learn. And I'm going off expereince with older, lower capacity machines, as well as conversations with dozens of other operators who are much more experienced than me. But I would suggest that you call and talk to Marvin Gordon, who owns this site and who's number is on the front page. And also the good folks at Hillco. Marvin can also put you in touch with the man that designed the disrupters, as well. Between these three, they've forgotten more about Axial Flows than I'll EVER know. I've talked to CaseIH reps who've poopooed the cover plates, disrupters, and so forth. But all these products are tested and in the right conditions they sure do work. I really wish the good folks at CaseIH would take notice of these fine people, and be a little more open minded. I'd be willing to bet that your problems, as well as those of numerous others could have been alleviated before it got to the point of a trade. Chads
