IMG_9381 Triple D
During the 1950s farmers in the United Kingdom in need of high-power tractors had few options. Essex farmer George Pryor developed an ingenious solution to the problem by creating his own tractor. He did this by purchasing two Fordson tractors, removing the front wheels and axles and linking the two by means of a turntable which provided the steering action powered by hydraulic rams. This left him with a double-engined four-wheel—drive tractor capable of producing more power and outperforming any of the conventional tractors on the UK market at the time.
The main disadvantage with the Triple-D was the lack of suitable implements for such a powerful tractor, this meant that Ernest Doe & Sons also had to develop and build a range of implements to sell with the tractors.
Other disadvantages stemmed from the use of two engines, this made controlling the tractor more difficult because of the need for two gearboxes. There were two engines and gearboxes to maintain and repair and the probability of breakdowns was increased.
