SE IA | Used to pull a hopper bottom semi trailer with tractors. Make sure you have plenty of tractor on it or it will shove you around. When the tandems on the dolly are headed in one direction they have to be dragged to turn them, I spun a tractor out (in a circle) more than once trying to turn that thing. I put some small diameter hydraulic cylinders on the trailer to run the slack adjusters for brakes. IA DOT never bothered me and they had plenty of opportunities. | |
