Dinky Toys 27n/301; Field Marshall Farm Tractor

Dinky Toys Farm and Garden

This Field Marshall tractor must have looked like an antique when it went into th Dinky range in 1953, they kept it in production until 1964. It is always orange in colour with initially silver wheels in cast metal. These were sometimes silver and sometimes green. By the end of production the wheels had changed to green plastic and the all-over tan coloured cast driver had become a detailed plastic figure in blue overalls. Late releases are rare. At release the number was 27n, changing to 301 in 1954. The real tractor was generally green in colour.

The Field Marshall tractor was a bit of a throwback to very early internal combustion engines. They were single cylinder compression ignition engines designed to run on low grade fuel oil.

To start the Marshall a smouldering piece of special paper, containing saltpetre, is inserted into the cylinder head by means of the special screw-in holder in the cylinder head (this smouldering paper acts as a glow plug).

The engine is then turned over with a starting handle placed in the starting dog on the flywheel. This is aided by the decompression valve, which decompresses the engine and makes it easier to turn over to allow the flywheel to gain speed and momentum to turn the engine through compression, and get the engine to fire. A spiral groove on the perimeter of the flywheel carries a wheel on the decompressor mechanism and is used to determine the number of revolutions before the decompressor disengages. This is generally up to three revolutions, but can be anything up to six revolutions. Depending on the condition of individual tractors, it may need considerable physical exertion to start a Marshall.

A cartridge starting system is also fitted to the tractor. A shotgun type blank cartridge is loaded into a breech on the engine's intake system. The smouldering paper is placed in the cylinder head, and the cartridge is fired by tapping the base of the protruding firing pin with a hammer. This puts a charge into the bore, sending the piston through its stroke, bursting into life. This method, however, deposits carbon which often causes jamming of the decompression valve if cartridges are regularly used. It also puts significantly more strain on the engine.

Alternatively you could buy a Ferguson or a Fordson and have a normal life.

In the autumn of 2020 I acquired a collection of repainted Dinkies with some eccentric representaions of the Marshall as shown below - check out the drivers
