The Overtime and John Deere’s Waterloo Boy tractor of the early 1900s are closely linked in that John Deere bought out the Waterloo Tractor company in 1918 to create its first tractor and to take hold of the yellow and green colour for its machines that now remains a world copyright for the American brand.Harry Ferguson had his own part to play in the early success of the Overtime tractor. From a period of between 1916 and 1918 when John Deere took over the Waterloo Boy factory, Harry Ferguson was one of the first Irish agents for the Overtime tractor. The tractor was a Waterloo Boy in every sense, apart from its different colours.
