Harry Ferguson's TE20 Little Grey Fergie tractor revolutionised farming in Britain and around the world, from 1946. Harry's invention of the three-point hydraulic linkage for attaching implements remains the basis of modern tractor design, as the depth of the plough could be adjusted to plough more efficiently. His aim was that this tractor should help to eliminate poverty and hunger, because the tractor could plough more quickly and with less effort than a horse or hand plough - an acre an hour, instead of an acre a day with a horse.
