I am trying to understand how those four factors relate to each other. Specifically I am looking at two tractors and trying to figure out why one has more HP than the other. I have an MF35 gas which according to tractordata should have 32 on the drawbar and 37 on the PTO. It has 134 CID. I am planning to soon acquire a Farmall H which is only rated at drawbar 24 and belt 26 yet has a 152 CI engine. Is the difference in the RPM the engine runs, in the design of the engine or gearing or is it something else I haven't thought of? Which one would get better fuel economy doing the same job(say, pulling a wagonload of firewood)? I am sure there is an obvious answer to this question, but I am not clever enough to reason it out. Thank you in advance to anyone who responds.
