The Doe Triple-D: Britain's Strangest Tractor That Worked

What happens when a frustrated farmer bolts two tractors together because one simply isn't powerful enough? The answer is one of the strangest—and most legendary—machines ever built: the Doe Triple-D. Born from the heavy clay fields of Essex, England, this incredible double-engined tractor shocked the farming world with twice the horsepower, four-wheel drive, and a design unlike anything that had come before. Mocked at first as a bizarre experiment, it went on to out-pull every British tractor of its era before eventually becoming one of the most valuable collectible tractors ever sold at auction. In this documentary, we explore the remarkable true story of George Pryor, Ernest Doe & Sons, and the engineering breakthrough that briefly changed British agriculture forever. From two drivers steering one machine to exports across the globe, discover why fewer than 500 Doe Triple-D tractors were built—and why collectors now pay tens of thousands to own one.
