Dad's first tractor was a McCormick Deering 10-20, I got to ride with him as he plowed, can still remember how it tickeled my bare feet and the sound of the growling gears. He traded for a Farmall Regular, steel steering wheel that would break your hand if you didn't hold just right. Traded that for a JD B and that was the first one I got to drive, many hours plowing and discing and 2 row cultivator, still had it when I moved to town in '62.
