The fuel can be a critical issue. I don't know what your weather is like. We had a fleet of rental crawlers, log skidders, and backhoes at our Deere dealership. Very often equipment was out in temperatures of 20-30 below F. At those temperatures, it's not easy to keep diesel fuel running. We mixed all our winter fuel with 50% kerosene and also used an anti-gel additive (usually Power Service).
Some diesel equipment will keeps its own fuel warm once running, and places in the extreme north keep their engines running all winter, night and day.
None of this probably relates to you and your tractor. But . . . the new pump diesel, by federal mandate June of 06, will be ultra-low sulfur and very low lubricosity. What this means is - if you plan on using highway fuel from the pump - and not farm or "off road dyed fuel", you could have wear problems if your Ford has a distributor style fuel injection pump, e.g. a Roosamaster/Stanadyne or CAV rotary. Those pumps are NOT designed for the new fuel. To prevent problems, if that's what you have - you have several options. Add some oil to your fuel - Dexron, 2 stroke engine oil, etc. Or, use the cheaper off-road fuel - assuming the stuff in plain-old heating oil, and not dyed pump fuel. The companies that make the rotary injection pumps, e.g. Stanadyne and CAV sell "Arctic Grade" parts to upgrade the pumps - but that's a big and . . in most cases, a unnecessary expense.
By the way, if your Ford has an in-line pump, e.g. a Simms or CAV, then you probably have nothing to worry about. A three cylinder engine with an in-line pump actually has three injection pumps instead of one - and each one is a plunger type. These types of pumps handle modern fuel much better than rotaries. The fuel plungers don't need as much lubrication, and the camshaft that drives them usually uses engine oil for lube. The rotary pump, however, for a three cylinder engine, has a small, dual plunger pump that does all the pumping for all three cylinders, but does them one by one, by directing fuel through a distributor head. This head works on extremely close metal-to-metal tolerances, and relies on the resident diesel fuel for all it's lubrication. This is the part that fails when it lacks lube, or gets water in it, or suffers an extreme temperature shock.
