The Field Marshall Series 3A is a tractor; built in 1952. Field Marshall is a tractor brand of Marshall, Sons & Co. of Gainsborough; the Series 3 and 3A are known for their single-cylinder two-stroke diesel engine. The engine is water-cooled, which keeps operating temperatures even under sustained load. The model uses rear-wheel drive. The production site is listed as Gainsborough, Lincolnshire, England. The listed predecessor is Field Marshall Series 3.
Tractors of this kind date from a time when engine power replaced draught animals, steam engines and hand labour on farms. They are simply built, with few gears and low road speeds, and were used mainly for ploughing, haulage and belt-driven work. For collectors and restorers the data plate, engine number and correct assignment to a variant are decisive, because versions of one type often differ only in details. Today such machines are found mostly in collections, museums and at rallies. Spare parts for tractors of this era today mostly come from reproduction, donor machines or collectors' exchanges. Knowing the original specification makes it easier to recognise conversions and later changes.
