I think I know the springs you're talking about. They seem to return the steering levers to neutral from reverse, but not from forward. The springs compress when levers are pulled toward rear of mower. On the mower I have, with the engine not running, if steering levers are pushed forward they will not return to neutral. To me either the dampeners are not self centering or they are not functioning as they should. I will call the dealer today to find out if they know whether the dampeners are self centering.
