Field-Marshall Tractor
The Field-Marshall and its tracked stable-mate (Marshall-engined Fowler VF and VFA), were distinctive because of the use of a single-cylinder two-stroke diesel engine (of about 6-litre capacity) coupled to a very large flywheel, whereas tractors such as the Fordson N used a multi-cylinder engine. This single-cylinder design was quite common in Europe at the time, the Lanz Bulldog being another example, however, the Lanz used an hot bulb engine.
