Joe: Interesting part about your post is IH quoted different figures for each of A, SA, SA1, 100, 130 and 140. The first two having 113 cu in engine and the later four having 123 cu in. Engine rpm went from 1400 in the A to 1575 in 100, 130 and 140. That 1575 figure I just took from IT manual and I seem to remember IH quoting 1650 somewhere re 130, years ago.

Over the years I have owned 6 of these offsets and really never paid much attention to hp as they were designed to do specific jobs where hp really never counted. While I realize three individual tractors are not much of a test, now that I have the time to play around a bit, I really can't see much difference between my Super A, 130 and 140. When it comes to power they are so close, I wouldn't want to call one over the other. Traction is a bit different as my Super A has 9.5x24 no weight added. 130 has 12.4x24 with wheel weights and 140 has 11.2x24 with chloride. When it comes to a good pull requiring traction the 130 and 140 do have the advantage. However I'm also thinking because diameter of the 9.5x24 tire is substancially smaller, this tends to make the Super A look great on the horsepower side.

One would normally think of the C-123 tractors being substancially more powerful. One thing I learned in my years around tractors, and much bigger tractors than these, is more rubber is the very best way to put horsepower on the ground. However when you start increasing the diameter of that rubber you better have the horse power to turn it.
