I have a 1999 Case 1845C. I used it about a month ago to move some heavy snow. It worked perfect. After using it I put it back into an unheated garage. Well, today I went to get it ready for an upcoming storm and it started fine. After letting it warm up I went to back it out of the garage and the right side won't move. You can hear and feel the right side trying to move. The left side is fine. Any suggestions as I am going to need this thing tomorrow. Thanks, Bryan
