Yep, to make more horsepower it takes more RPM's. The rpm's these tractors run at wide open in stock form is barely above fast idle speed for an automotive engine.

But the tractors are geared to where that's all the rpm's it takes to do what they were designed to do.

27 horsepower might not sound like alot now, but back when tractors first came out, they were intended to replace real live oat-burning horses, where 2, 3, and 4 horse teams were common. The "horsepower" rating of a tractor isn't truly equal to the number of acutal real horses it would replace, it's really more a "rule of thumb" measurement of the amount of work an engine can do over a set amount of time.
If you hitched 27 big stout horses to the drawbar of an H to see which would outpull the other, they'd drag it around like it was a cardboard toy. Lots of guys around here used to feed 6 ton haystacks on rolling sleds pulled by 6-horse teams, but it usually took at bare minimum a 45-50hp tractor to pull the same load once people made the switch to tractor power.

Sorry for kinda going off on a tangent there, but I like to talk about that kinda stuff!
