Just because it's running doesn't mean it's putting out that much HP. Hell, you can idle and tinker one around all week and not burn much fuel. :lol:
The HP/Hr per gal is when it's at or near peak HP. As it should be. Pulling a hayrake? No. They all get good consumption rates then.
What part of Full Load did you not understand? :?
All of it. Because chances are you have never worked your tractor under a FULL load at peak HP for more than an hour as they do under the fuel consumption tests.
6 gal per hour is probably about average for a 95 HP tractor under full load. But when it's making 20 HP the consumption goes down to about 2-3 gallons per hour.
I have an 85 PTO HP tractor that is rated at 5 gallons per hour. But when doing menial chores it might take 2-3 days to burn a 40 gallon tank.
We're not exactly comparing apples to apples here.

The fuel consumption measurement, horsepower-hours per gallon (hp-hr./gal.), has become the standard used for comparing the efficiency of all agricultural tractor models. Measured directly, it means that burning one gallon of fuel in the tractor at full load and at rated engine speed produces a certain amount of horsepower for an hour. The higher the number, the greater the fuel efficiency; that is, more work is being done with a given amount of fuel.
