Back in high school, our photo teacher lived on a farm and swore by Ford tractors. Nothing else would do. Not Case, not Massey-Ferguson, not International Harvester, not John Deere. It had to be a Ford. And the genesis of the Ford tractor was the Fordson, the product of an intially-independent outfit set up by Henry and Edsel to build an agricultural vehicle that could run all day doing the work of four mules. That is, assuming you were able to get it started in the morning and kept an eye on all of its precious bodily fluids. Needless to say, the Soviets bought 24,000 of them.
