I found this while looking through some You Tube videos.

Someone on AgTalk has a signature line, To this effect: The Farmall M is what made America.

In their day pretty good stuff. We still have Dad's H he bought new in 46,and a Super C Grandpa bought new in 52, it's raining might as well have a little entertainment. As a kid I never ran an M much, too hard to push the clutch. Then we got a 560, which I did not run either, too small for the "big Tractor" The 706 was the first "big tractor" I plowed and disked with. We still have the 706, I just added the 2nd hydraulic to that tractor a couple years ago.
