I don't know where you live, but we took ours to a Ford/New Holland dealer in SE Minnesota, they work on them all the time.
They were fair and brutally honest!! We bought a couple of seasons on two bands, just as was promised and then it fried. The total rebuild wasn't an option so we changed over to a manual that was available at the time.
The dealer is in Spring Valley I think, I'd have to look it up, but I can if you want.
