In 1938, Minneapolis-Moline unveiled the UDLX Comfortractor to 12,000 farmers in Minneapolis. It was revolutionary: the first production tractor with a factory-built enclosed cab, complete with a heater, radio, cushioned seats, cigarette lighter, and a top speed of 40 mph. It was meant to change farming forever. Instead, it became one of the biggest commercial failures in agricultural history. Only 150 were ever built. Just 100 actually sold. The rest were stripped of their cabs and converted back into standard tractors. In this video, we explore what went wrong with the UDLX Comfortractor, why farmers rejected a machine that offered everything they claimed to want, and how the timing of the 1938 recession destroyed Minneapolis-Moline's ambitious vision. But this is also a story about being ahead of your time. Every innovation the UDLX introduced, from the enclosed cab to the shift-on-the-go transmission, eventually became industry standard. It just took another 30 years. Today, surviving UDLX tractors are among the most sought-after collectibles in the world, selling at auction for up to $200,000. This is the story of a glorious failure.
