How much mowing time do you get on a tank?

[Fatdaddy]

Of Diesel? My 326 I filled up both tanks with 188 hours my tank light comes on at 191.5
It seems my right tank with the gage gets more time? I will check it..
Just wondering how it should be?

Any thoughts on this I might need to know
I feel like my exmark gas got more time on a tank??

I have found the tank with the light is not and accurate indicator of how much fuel is in the tank. I can usually run a couple of hours with a solid light. The best thing to do is when the light comes on switch tanks, then when you are done cutting fill the tank and see how much fuel it takes.

I've found better milage with the diesels. But both usually burn about a gallon an hour.
