Allis-Chalmers of Totton, Southampton

1947 Opened a factory in the United Kingdom. The first tractor manufactured in the United Kingdom was the Model B which was made at Totton, Southampton, using components imported from the United States. Later the Model B was produced entirely in the United Kingdom.
Company moved to Essendine, Lincolshire
1953 Became private company.
1955 Introduced the Model D270. The D270 and later models featured live power take off operated by a hand lever. This was especially useful when using another Allis-Chalmers' machine - the Roto-Baler - which was used for making hay bales. The live power take off reduced by half the amount of clutch pedal movements required to make each bale.
The ED-40 tractor, built from 1960 to 1968, ended Allis-Chalmers' British production. This tractor featured a 37 HP diesel engine originally and later a 41 HP engine with a better hydraulic system.
