So, got the gator back from my J D dealer. They replaced the clutches on my 550 and the belt under warrantee, no cost to me. The mechanic said because of the new belt it might take about an hour of running before the shifting got smoother. If it gets any smoother it will be better than my car! So far, this thing is smooth! Shifts out of reverse into forward, I even have been able to find neutral! Good job from my dealer! Love this machine!
