Bill, they had a Big Bud at the 3-I Show in Gt. Bend, Ks. a few yrs. ago. It had a 450hp eng. driving the front 4, and a450hp on the back 4. I can't remember what eng. , but I think it was Detroit. They would'nt say how much fuel it used per hr. They didn't make too many of them. We have a Versatile 9680, with an N14, 350hp, traded for it last yr. , our old 875 Versatile was rated 280hp,(we had it 18yrs. ) it burned 12 to 13 gal. per hr. , the 9680 350hp burns 7 to 8 gal. per hr. pulling the same implements, so they have really improved the newer Cummins eng.
