I have a craftsman LT1000 lawn tractor model #917.2720601. While cutting the grass I put the Hydro Gear in Reverse and it would not go, I put it back in forward and would not go... Had to push back to the garage. Took the back trailer hitch plate off to look at the linkage... everything seems find and the tractor made no noise when it happened... How do I fix this so the tractor will move again?

Hi,
I will be in the idlers(one or both) #38 and #47 or the clutch reurn spring #55 or the belt #57 or a combination of them. Picture attached.
Peace,
Clarke
