What perfect timing for my machine to start giving me fits. On my last job today my permagreen ultra would keep going (wheels spinning) even when I took my hand off the throttle. The cable is not stuck as the spring takes it back at the engine so I know that is fine. If I am going full speed and take hand off throttle it will slow down but wheels keep spinning and going forward. I have to pop it into neutral or power down to stop. Same with reverse. Its like the clutch is continuously spinning? Clutch bad? Called Permagreen, but Bill was gone for the day. Hopefully he gets back to me in the morning or else I am taking it up to Finch John Deere to spend some $$$. Can't be without it too long this time of the season. Any diagnoses out there?
