I couldn't get the image to display so the above is a link to the image itself.
Only things I've noticed different on various year models that have not already been covered are, some of the parts had running changes/upgrades, like the previously mentioned PTO, the oil filter size, the lower shaft front seal retainer for the transmission originally was pot metal, and while substantially lighter than the later one, it was also much weaker, and thus prone to breakage when torqued down, especially if done so by Charles Atlas. The later one is a direct bolt on replacement though, and much stouter. Speaking of lighter, the earlier tractors generally had lighter castings in some areas, especially during the war years, when all metals were rationed and thus very hard to get. For instance, on my July, 1940 manufactured H, the transmission top cover is light enough I can lift it on and off by myself, but later model ones I have always needed help to do so. Also, the early models had a different key system to hold the rear casters in place on the axles, using a separate key top and bottom instead of the one in the hub being cast in like on the later models. I have a set of 1946 coded casters done like this.
