 Through the 1950s, DAF was a major supplier to the re-equipping of the Dutch Army's softskin vehicles, with models such as the DAF YA-126 and DAF YA-328 'Dikke Daf'.These used the all-wheel drive H-drive developed from the Trado conversions.In the end of 1954, Hub van Doorne had the idea to use belt drive, just like many of the machines in the factory that were belt-driven, to drive road vehicles.
