Last year I bought a 21" JD self propelled mower. The cable broke for the self propelled system and I called JD to get a new cable sent to me. They tell me that I have to take it to dealer for warranty repair. I dropped it off at the end of the season. Never heard anything so I called the other day and they have no idea what I am talking about. No workorder or anything. Hmmm this should be interesting.
