Many's the furrow I ploughed on my neighbour's wee Fergie diesel. Does anybody remember the Fordson tractors which were fitted with road tyres and mudguards and used for airfield use? I think most RAF haulers were David Browns but I do recall Fordsons somewhere, maybe Binbrook in late 40s?
The Fordson ran on TVO and a friend has a preserved one, complete with magneto ignition. It's a monster of evil disposition, hand starts (the only way) can not so much break the wrist as hurl one into orbit
The Fergie of half the weight runs rings round it, but of course you need the weight to haul a Lancaster etc.
