I told Mueller that it looked like that poo keeps up just fine with his 850. He said it does on the end of a rope. I think that was Coulter Todd's 850 poo. He isn't very lucky because I think his last years axys blew up also.A friend towed one out from Big Sky this weekend with a locked up motor. Had 50 miles on it. Saw the video of 3 sleds linked together (2 pulling) to get it up the hill from where they were. I don't know any more details other than that.
