Tractors fitted with factory steel wheels had a 3-speed gearbox, done by removing a shifter fork from the regular transmission. The U was also sold as the United Model U (1929-1931), and was distributed by the United Tractor and Equipment Corporation. United was a group of Fordson dealers who contracted Allis for a new tractor, once Ford stopped North American production of the Fordson. |
