The Fordson Major and Power Major represent robust agricultural tractors, produced from 1945 to 1957. These heavy-duty machines, developed by Ford-Ferguson and manufactured in Dagenham, UK, and Highland Park, USA, were designed for demanding farm work. Key features include their powerful diesel engines, typically a 3.61 L (220 cu in) four-cylinder OHV unit, and a versatile constant mesh gearbox offering six forward and two reverse speeds. The engineering focused on durability and reliability, making them a staple in agriculture and a direct competitor to models from Massey Ferguson, John Deere, and International Harvester of their time.

This Service Repair Manual, identified as a Supplement to the Workshop Manual, provides comprehensive repair information and details on changes made until the end of production for the Fordson Major and Power Major. It is intended for use in conjunction with the Fordson Major Repair Operations Manual. The manual covers all major systems, including detailed procedures for engine overhaul, cooling, fuel, clutch, gearbox, steering, axles, brakes, and the electrical system.
