Well another trip to the dealer and I had it all checked over as much as they could with out pulling the hydro.They drained trans oil and magneticlly checked it all good. So I drove home (150 miles) got home it did the same thing it would only move 2 feet or so on the trailer Of course it didnt do that after trailering it to the dealer. I jacked it up ran it forward and it made 3 screeches then it was fine worked great. My local cub dealer said the hydro is running out of oil or my disc brake is wedging . It did bounce around alot the roads are rough and it was full of road salt spray. Any ideas ??
