The very first IHC 1486 tractor that rolled off the line is coming up for sale at auction in the St. Louis area on December 2, 2017, Serial No. #8601. Here's a picture of it:
The tractor is showing 2,200 hours. I will try to get more history/info on this tractor as we get closer to sale day. Our friends at Sullivan Auctioneers are having this sale (http://www.sullivanauctioneers.com).
How high do you think it will sell? I've watched the last 5 years or so as the 1st and last SN# factor has seemed to amp up in importance. Bidders tend to be more aggressive at the once in a lifetime chance to buy and own the 1st or last tractor model ever made. This has been particularly true on iconic models from the 1960's - 1980's.
So this 1976 IHC 1486...right in the bullseye. Bidding could be hot I suspect.
Here's a look at the 10 highest auction sale prices I've seen on IHC 1486 tractors, which were made from 1976 - 1981:
