High 2, the reason I bought them in diesel was everything we have is diesel, but the option was $1500 more than gas, they do shake a little when they are idling, and after I got them they came out with the 60hp (I think) fuel injected gasser, and it goes about twice as fast as the diesel, I think the gasser red lines at 5-6000 the diesel is about 3000 rpm
But they still go 35. I am going to start switching everything but the tractors to gas, tired of getting hosed on the price of diesel. I started running diesel when Ford came out with the 6.9 in 83, mostly because it was cheaper then, and they didn't watch burning the off road as much as they do now LOL
