I'm searching for my Dad's former 1959 JD 630 2-cylinder gas farm tractor, Serial number 6306529. The tractor was traded several years ago to a farmer/dealer in Wisconsin. If anyone can help me in my search I would greatly appreciate it! Is there any national database available that might give an indication if any parts, etc. that may have been purchased for the tractor over the years? Or is it better to go to a JD dealer and have them do a search of any parts sales per the tractor serial number and maybe get lucky? Thoughts?
