I am hoping my fuel usuage is way off as I have not really run this at pto speed for much time I try to stay between 1800-2200 for just little jobs. This summer I will know better as I plan on restarting my hay operation with a mower/conditioner behind this tractor. Coming from my old gas mf 35 I am using a lot more fuel for similar tasks Mf 35 normal rpm was 1200-1600
