Careful on the gas tank thing. I ran one tank out and filled it at the station and I'm only getting approx. 5.6 gallons into a tank so I think Gravely may be exaggerating their capacity. I'm going to recheck things as I go. I won't be too happy if this thing only holds 11 gallons total instead of the 13.4 they advertise, but this also may make the gph look better.
