I think the last year on this model was 1983. The name was changed to 9720 in 1984. I can't remember the exact dates for sure without consulting my archives, but I think that was also the same year M-F broke up, leaving MCC to build the combines. White, already on the verge of bankruptcy even when the 9700 debuted, sold the 9720 and its smaller companion model to MCC in 1984 or 1985. Massey kept the same number on it for a while, then changed it to 8590. I think Massey only kept this one for only a year, maybe 2, but dropped the big 8590, but kept the 8570 well into the AGCO years. I haven't heard of or seen any of these in 5 years, but it doesn't mean they're not around. I posted a search for White 9700 owners on the Massey page, but haven't located any. This is a rare combine, indeed, but one I'm sure could give any of the Class VII machines a run for the money.
