Inventor Harry Ferguson changed the face of farming forever when he came up with a simple three-point linkage for tractors and patented it in 1926 - enabling farming vehicles to carry and operate implements and attachments directly rather than towing them like a trailer. His company grew and in 1946 began manufacturing the 'little grey Fergie' Ferguson TE20 - the blueprint for the modern tractor. Both linkage and tractor have gone on to become farming icons, cementing Ferguson's place in history. Ferguson: A Farming Revolution charts the story of Harry's incredible success.
