International Harvester C-Familie
5 models in this series
International Harvester 946 to 1055XL (1970s) – the six-cylinders from Doncaster: XL for the comfort cab, throughout a 5.1 to 5.9-litre diesel, 62 to 74 kW, 318 to 381 Nm
International Harvester built its own range of larger six-cylinder field tractors for the European market at its British Doncaster plant, to which the 946, 955 and 1055 models belong. The number in the type designation orders the power class in ascending order, the XL suffix marks the more comfortable cab specification against the base version – the 955XL and 1055XL offered a roomier, better-insulated cab compared with the 946 and 955, with largely the same engines underneath.

The register lists 5 versions uniformly with six cylinders, engines of 5,073 to 5,867 cm³, outputs of 62.2 to 74 kW and a rated speed around 2,200 rpm. On four models torque falls between 318.8 and 381 Nm; service weights range from 3,600 to 4,370 kg, lengths from 3,912 to 4,194 mm.
The Doncaster six-cylinders occupied the upper mid segment of European field tractors in the 1970s, competing with Ford, Massey Ferguson and the then-strengthening Fendt range; IH tractors were technically regarded as solid, if less widespread than the established European brands. After the sale of IH's agricultural division to Case in the early 1980s, the Doncaster models were carried over into Case IH ranges.
On used tractors, operating hours, the condition of clutch and multi-stage gearbox, hydraulic pump and linkage, the tightness of the cab glazing on XL models, and rust on frame and wings count; parts supply runs through Case IH as legal successor.
