Mc Cormick International – other models: from the British B series (B-250, B-275, B-414) built in Doncaster to the Mtx 140 and XTX165 of the revived brand, 23 to 123 kW, four- and six-cylinder engines
This collective page gathers the Mc Cormick International tractors the register could not assign to a named range – from the post-war British classics to two current models of the revived brand. International Harvester was formed in 1902 from the merger of the McCormick Harvesting Machine Company with the Deering Harvester Company in Chicago, and from the 1950s built the B series at its English plant in Doncaster, sold depending on the export market as "International" or "McCormick-International"; this is why B-250, B-275 and B-414 appear in the register several times with slightly different spellings. After the 1985 sale of IH's agricultural division to Case the McCormick name lay dormant until the Italian Argo Group revived it in 1999 for a new tractor range; the Mtx 140 and XTX165 listed here come from this second chapter of the brand's history and represent the mid and upper power segments.

The register lists here 11 versions with 23 to 123 kW from four- to six-cylinder engines of 2,360 to 6,700 cm³, unladen weights from 1,550 to 7,000 kg, gross weights up to 11,500 kg, lengths from 2,840 to 4,760 mm and widths from 1,550 to 2,510 mm.
The B series was among the most widely exported British tractors of its era, as common in Commonwealth markets as in continental Europe; the modern McCormick brand today competes as an Argo Group marque alongside Landini and Deutz-Fahr in the mid-price segment, chiefly in Europe and export markets.
On the B-series classics, what counts on a used buy is engine and wing originality, corrosion at the stub axles and brake linkage, and the availability of parts through vintage-tractor specialists; on the Mtx and XTX, turbocharging, common-rail technology, hydraulics and electronics come to the fore, with parts running through the Argo Group's McCormick dealer network.
