I do not think the fuel choice was a dealer option as the Farmall Super A and the Farmall C with the c113 engine had different heads for the three fuels, gasoline, distillate and kerosene. The kerosene had the lowest compression ratio, about 4.4:1, the distillate was higher at about 4.7:1 and the gasoline engine about 5.6:1. The kerosene engines and operation were similar, the manuals covered the distillate option and then said that the kerosene engine was operated in a similar manner, one started on gasoline, when the engine was hot the change was then made to distillate (or kerosene). The engine had to be kept hot, hence the need for shutters.
The distillate tractors, besides having the lower compression heads, had the small gasoline starting tank, attached to the right-hand side of the head, adjustable temperature manifold with heat shield, different carburetor (adjustable jets and easily operated drain), water temperature gauge (above the governor) and radiator shutters. All this would normally be factory fitted. In New Zealand in the early 1850s, kerosene was a third of the price of gasoline and was a very popular choice. Distillate was unknown. When gasoline without the road tax became available for farmers the change form kerosene was fairly rapid as it avoided the starting difficulties with kerosene but also the having of two sorts of fuel around and the more frequent oil changes as well as the daily draining of the top of the sump were no longer required. Most of the shutters were removed and tossed into the back of the tractor shed where they got damaged and are quite difficult to find today. The starting tanks were usually retained to act as a reserve tank.
All one needs to do is read a Farmall manual written from 1939 to about 1952 for all the details. IHC tractors in the 1930s were similar except that kerosene was the normal fuel and radiator curtains were more common than shutters. Radiator shutters appeared about 1937 and temperature gauges appeared about the same time.
I have a 1948 Farmall Super A which is set up for kerosene, the only missing part is the heat shield (to be removed when running on gasoline) and I have yet to free up the manifold heat control valve. My 1941 W-4 is also a kerosene tractor which was missing the heat-shield and the shutters. Again the manifold heat control valve needs freeing. Otherwise, both manifolds are in very good condition. I have since found a set of shutters for the W-4, the same as those for a Farmall H. However, as kerosene is more than twice the price of gasoline the missing heat shields are not of great concern.
