Same kind of plastic shaft coupling failure that others have experienced. Same run-around from local Poulan repair shop. Same frustrating experience from Poulan trying to get warranty replacement (they finally did replace the unit). The product is good -- while it works. But anything more than what you can cut with a manual pole pruner (~1") seems to overload the shaft coupling. I'm afraid to use the tiller attachment becasue it seems like it would be a much heavier load on the coupling. This must have been designed by the Poulan CEO's idiot son and no one has guts enough to fix it.
