I have a 20 acre hobby farm with a few old MM tractors. Nothing rare or fancy. Just a 670 super on a loader and snowblower. U-302 Super to pull a hay wagon around for the kids. And a few old letter series in the barn.
When my brother and I sold our 300 acre farm in the late 1980s- it was very very common to see MM or Oliver tractors running a whole farm. Heck, in 1989 our G1355 was only about 15 years old. That seemed pretty new for us at the time! My brother's mint condition G708 didnt even sell at our farm auction because nobody would bid the $2000 reserve! I guess nobody found them to be rare or desirable back then.
Seems like times are changing fast and not many MM are still in working roles on the farm. My hats off to those still running their Molines!
