last year we went from our 1660 CIH to our R42. We bought a 816 flex head used, that had the tigers on it. In the deal with the dealer we asked for the SCH, since we did not ever have one, but heard about them from this web site, (for all the colors). WE did have tigers on the CIH 1020 15' head years ago and put the Creary Golden cut(spelling)3" on it about 7 years ago. We thought that was a improvement over the tigers. I used the 816 as we bought it with the tigers, for a few days in the start of harvest last year. We got a rainy day and pulled the tigers off. Remembering why we went to Creary's. The SCH was like cutting butter compared to the tigers. We continuously no-till everything. The SCH went right through corn and milo stubble in the bean fields. Even being a bit damp Sunday this week it cut great. I am sure with the tigers I would have been setting in the shop waiting or out bull dozing residue (which I hate, it exposes the soil and that is where I will have weed pressure next year) Now comparing the Creary Golden Cut to The SCHIJ I would go with the SCH. I was impressed of the quality of the parts. And those Creary hold downs can be a pain to get set right, and if you have short beans and you happen to get a row right over the top of one, good luck geting that to feed there until you move over a foot to get the wad to come in the machine. One thing with the SCH, you need to make sure you are lined up true on the pitman bearing bolt, and sickle anvil. The sickle sections run very close tolorances in the guards. I hope this helps.
