hp is a vastly missleading number for measuring the amount of work a engine can do, on the motorcyle engine, no way can it do the work of a 120 hp tractor, s simple demonstration is easily done, take a old 8n ford, rated at 26 hp, hook it to your suburban friends box store super garden tractor also rated at 26 hp, briggs, koler kawasaki, it doesnt mater, [ no cheating by lifting the garden tractor with the fords 3pt hitch now] but in a straight drawbar to drawbar pull, the old ford will make the box store unit look , well, just silly while the ford does weigh 4 or 5 times what the box store mower does, it also has a nice big heavy flywheel in it which produces tourque which is the engines ability to keep twisting under a load, look at anbother, a big block chevy v-8 can be built to make 425 hp pretty easy, my pete also has a caterpiller engine rated at 425 hp, now the chevy is producing around 500 foot/lbs of tourque at 425 hp, the cat dyno'd in with 1,877 ft/lbs, of tourque, obvisouly one engine can do a vast amount of more work than the other even though both are rated as having the same hp, i think that is why the nebraska tractor tests were invented, back in the day, to provide a realistic way farmers can tell just how much work one tractor will actually do over another
