I called my salesman to discuss the problem and see if the block heater was under warrantee. He didn't answer so I left a very nice message. I just got a call from someone else at the dealership and they said they will pick up the tractor in a week to replace the block heater and adjust the timing! Not sure what has changed -- John Deere called them, I finally complained enough, they read this forum... but I'm not asking any questions and if this works out I might start buying by parts and my next tractor there.

Thanks to everyone for their suggestions. I am in a unique environment but heck the dealership is probably at 6000 feet and there are a lot of people that live at and above 8000 feet in Colorado and use these tractors for snow plowing and grading, so it is part of the equipment business here.
