An original IHC sales brochure I have, from about 1935, gives 4265 lbs. "shipping weight, approximate" for the 10-20. In the 1923 Nebraska Test (according to Wendel), the weight is given as 4010. The 1927 test of the 10-20 gives 5028 lbs., again according to Wendel. I have doubts about this last figure.
It would not be surprising to find some differences in weights over the years. There were minor differences between the earliest tractors and the later models. Early ones had an air cleaner filled with water, as opposed to the oil-filled air cleaner that came along later. The governor linkage was in the open up through about 1926 (in other words, the enclosures for the governor linkage might have added a few pounds to the overall weight). There were also some differences in the manifolds over the years. How these differences could amount to 800 pounds, I cannot imagine. I am more inclined to distrust the books written in recent years. It is easy to get a number wrong when there are so many models, dimensions, weights, etc., to put into a book. My guess is that the earliest number listed by Wendel is correct, and that the 4265 shown in the IHC brochure reflects the few minor changes that were made in this tractor over the years. I am extremely reluctant to accept 5028 lbs., even if the tractor had been weighed with all liquids to the top. The "shipping weight, approximate" COULD be without fuel and cooling water, but I don't know any way to find this out now. The radiator holds 9 gal., the fuel tank holds 15, and the starting tank holds 3/4 gal. Full fuel and radiator water would probably add about 200 lbs. to the total weight of the tractor. Water weighs 8.33 pounds per gallon, and gasoline runs between 5.8 and 6.5 pounds per gallon. I presume that kerosene would be a bit heavier, but I don't have any figures on that.
