When I brought my tractor home there was .2 hours on the clock. Dealer filled the tank at purchase. I know have 7.4 hours and am on empty by the fuel gage. I estimate 5 of the hours were mowing and the rest of the hours were various tasks. Mostly loader work. I’ll probably never try to track fuel economy on a tractor but am curious if anyone keeps up with their fuel usage for tracking gallons per hour? Would it be useful for any reason?
