Recently I "inherited" a 22.5 820 Flexhead in fairly good shape (new wobble box and decent tin)with a combine. We bought the combine (1480) primarily for corn as local opinion is that combine is not really suitable for use in soybeans (no chopper). Now my curiosity is up and we conventional till so the no chopper is really not a issue and I have been thinking of maybe trying this machine in beans (big mistakeIJIJIJ). locally I've heard absolutely nothing good about any IH flexhead, not even the newer 10 series. Is this head really that bad and should I just send it down to the local consignement auctionIJ I know they usually don't bring more then a few hundred dollars on sales. I've heard of a couple outfits that "rebuild" these heads to make them function better, but I am in SD and am not going to invest a ton of money shipping this head across the country when I can use a Bish adapter and run a JD flexhead (this is what most of the newer IH combines are running around here). What are the "problems" with these heads and is there anything I can do myself to improve this headIJ I have a fairly good shop and am a experenced welder and mechanic. Thanks! Doc Holiday
