Does anyone know how to adjust these control handles on the Scag SWZT? I Tried loosening the bottom of the rod and the top of the rod and turning the rod to adjust the control lever on that side. I went both ways and still can't get any action. The manual is vague on this and tells me nothing. The issue I'm having is in my left steering. When I pull the control lever on the left side, it doesn't return all the way back down. It releases to about 3/4 of the way and causes the mower to track to the side rather than going straight. I manually have to push the control lever back down to get it going straight again. This is the first issue I've had with this machine and is a bummer because I'm too far behind to run to the dealer, and tomorrow and Thursday are my VERY BUSY days. Any help is appreciated.
