Tons of those "data" site are full of crap poor info and the list goes on. Even the H has more HP than 25. [Reply]  [No Email]

No doubt they got their horsepower figures from the Nebraska Tractor Test results. Test #328 says the gasoline M produced a maximum 36.07hp on the belt and a maximum of 26.23hp on the drawbar. Test #333 says the gas H produced a max 19.84hp on the drawbar. Now, I will say that the almost every H and M has had the engine rebuilt at least once in the past with thinner sleeves and larger pistons thereby giving the engine more cubic inch displacement and thus more horsepower. That is why the M of today can produce 40hp because the engine has been rebuilt to Super M specs. [Reply]  [No Email]

You can get any amount of pull out of any size engine if you gear it down far enough and give it enough weight and big enough tires. My 544 can pull anything my 560 can and then some. Why? 18.4 tires with 900lb of CaCl solution in each. Yet I"d rather use the 560 for field work. Why? Because it does more acres per hour with a smaller implement than the 544 can with a bigger one. Power equals force times speed. "Pull" is just force. A 1hp winch can outpull your H but you wouldn"t want to plow with it. [Reply]  [No Email]

As to seeing if the 544 can outpull a winch, I"d have to find something to rig the winch to that the 544 couldn"t pull out of the ground. I"m not sure I own anything that stout since the old elm died. Plowing with Cables [Reply]  [No Email]

The horesepower ratings given are NOT actual engine horsepower ratings, but rather the ratings measured where the actual WORK will be taking place. You can go out and buy a garden tractor with a Briggs and Stratton engine that is rated at 25 horsepower, but I guarantee that garden tractor will not do the same work as a Farmall H, and as a further for instance, Before we even had tractors, farmers used horses, and just two big old workhorses were able to pull a one bottom plow, so why would a 25 horsepower Farmall H not be able to pull a 2-14s plow?
