Allis-Chalmers started manufacturing tractors in England in 1947. Gradually, most of the parts were also of British origin, including the electrical equipment made by Lucas. The manufacturing mainly involved model B. In the very early phase, a small batch of model WC was also assembled. From 1950 onwards, the English B model featured a straight front axle different from the American version. The lifting device was modified to a three-point hitch, but it was not on par with European tractors. British Allis tractors were also exported to Australia and Canada.

In 1954, the model D-270, a further development of the B for the European market, was introduced. Despite the model designation, it was most often equipped with a petrol or gasoline engine. The diesel version had a 2.36-liter Perkins engine. The diesel model had a 9" clutch instead of an 8" one. Unlike the American models, the electrical system was 12 volts. A new feature in the D-270 was a separate power take-off (PTO) clutch operated by a hand lever. The differential lock and weight transfer system were still missing. Alongside the standard models, there were also versions in production such as a smaller version in every direction and a version equipped with higher ground clearance.

In 1957, the updated D-272 replaced the D-270. The basic technology remained the same, with slightly more power from the diesel engine. The appearance was modernized and some parts were reinforced. Compared to its competitors, however, this successor of the B model was already beginning to appear outdated.

There is unusually wide variation in the technical specifications of these models as reported in different countries.
