Have you talked to Georgia Outdoor Equipment in Oakwood?
I have not used them for service, but have ordered Husqvarna lawn tractor OEM parts from them a few times. I was so pleased with the customer service, I called them again, and I live over in NW Georgia. I would expect the repair shop to be good as well, based on the parts service I received.
