He hasn't used it for a few years. He says that all it needs is new batteries and it would run. It has a hydraulic dozer on it, unless he sold that separate. The biggest problem he had with it was a bull gear that broke; that is apparently a week spot, but then he used it quite hard sometimes. He just got out of hospital today, so I doubt that he's in mind to discuss business right now. [Reply]  [No Email]

We were looking for logging ones, so that may have been more of an issue than other uses, and usually knowing about a potential problem can prevent it from becoming an actual problem.
