Ariens 42 Questions about how long gas lasts?

[Lschinaia]

Hey guys

Bought my Ariens 42 from the local dealer this week, got delivered yesterday! My only concern is how long does the 42 run on 2 gallons of gasoline?
Is it like 3 hrs? I have read and done all my research but still have not found this out. Right now mowing pretty slow because not used to the zero turn yet. So it seems the gas lasts a while.

Let me know.

'Ballpark' figure:

pounds of fuel per hour = specific fuel consumption x horsepower

The specific fuel consumption for gasoline engines is around .4 pounds per horsepower per hour

So for a 20 horsepower engine, that works out to about 8 lbs/hr. Gasoline weighs about 6.1 lbs per gallon, so an engine putting out 20 hp would be burning about 1.25 gallons per hour.

You can tell the boys who have done serious time on the land can't you.
My landlord always talks in gallons/ acre.
