I'm thinking Indydirtfarmer is right on this point. I have been to many a tractor pull and the blades that they use make short work of the leveling task at hand. With tractor pulls a flat track is absolutely necessary and they drag the blade after each and every pull. I'm not sure however if they are called arena blades cause a Google search doesn't find them. Shouldn't be to awfully hard to find the name if you go to the Tractor Pullers Association and just ask them.
