I have a TW 6 that I have had for almost two years now. I have split a tremendous amount of wood with it and really like the machine. The problem I have is I believe that the spindle (or the whole beam that holds the tank and engine up)) is bending. My dad followed me today going down the road and he thinks I'm getting a little bow legged on the tank side. Like I said I have used it alot. I have towed it alot (usually 5 miles or less) and don't think I have ever gone over 25-30 MPH with it. I wish it had springs, but it doesn't. Anyone else have this problem?
