I have a Scag Tiger cub that's about 4 years old that until now has been flawless. I've noticed that the right wheel is really slow in reverse, forward is fine. I have adjusted the tracking in the past, when it would pull to one side when going forward. I think it was the same side. Could it be that the hydraulics are getting weak on that side and I need to adjust both sides to slow down the forward, to fix the reverse? Any help would be greatly appreciated.
