I only mow a little over an acre but it seems like I am always out of gas. I have a JB and I may use it more than I think but it seems I am always going for the gas can . I had an 18 and a 20 hp before and they both seemed way easier on fuel. If I were to guess, I would say it is burning nearly 2 gallons per hour. I know it is bit bigger(1hp and 250lb) than my last tractor but do you guys notice it as well?
