Take it away Nick.


Foist, the question might be "how many horsepower-HOURS" of energy?"

And how much force times 176 miles?

Yes. That is the question required for a starting point...

And I dunno the answer.

I do know that the bigger tractors have 450+ horses available. We need a
farmer to give us (more like you ) some actual fuel consumption
figures.


I saw a show on discovery channel about the worlds largest tractors.IIRC
they used about 1 gallon per acre for one pass plowing.

Did you catch the width of the plow. Makes a little difference.

30' wide is approx.:
176/640 = .275 miles per acre.

Where 176 is the number of passes (1 mile each) with a 30' wide plow to
cover 640 acres (1 mi. sq.).

1 gallon per acre equals 1 gallon per .275 miles.
1/.275 = 3.64 gallons per mile (not miles per gallon).

Now I'll post this and then likely find somebody beat me to the punch.

Why assume a 30' plow? the tractors I saw would pull a 30 foot plow apart in
short order.There is such a thing as economy of scale.Just because someone
said 30 foot plow does not mean it has to be.Run the numbers with a 20 foot
and you will get even less efficiency.
