I wonder if that old Minneapolis Molines pulling tractor is still around. Ran on propane and was pretty dang competitive, won a few national titles with it but about every other time he pulled, thing would explode.
Cal Poly University San Luis Obispoo still has a tractor pulling team on campus. Last I saw they had 2 tractors, both Allison powered, one turbo and one injected. Their event should be in the near future. I think the Ag students and Engineering students combine forces on the team. April 14th 1pm
