I bet Randall learned his clutching on old 8N ford tractors with no synchros at all. Double clutching those envolves hands and feet!
Nope, never tried to double-clutch a tractor; and my grandfather used Deere tractors instead of Ford's (illegal) copy of Harry Ferguson's tractor.
But what I did learn was how to start out in a taller gear, with a heavy load and not much power on tap. 28 hp will actually move 10 tons of hay in road gear; if you know how. I looked up the specs just for fun; top gear on that tractor was 10 mph at 1250 rpm engine speed. Not all that different than 2nd gear on a TR3 (10 mph at 1170 rpm).
Should've taken a picture of it: My grandfather bought that Deere model 50 the year I was born, and my cousin still uses it to farm with! I was out there a few months ago, and he was hauling corn with it (not 10 tons worth, though, and probably not in 6th gear). It's been repainted a few times, repaired when necessary of course, but never "restored".
