Just as a follow up thought...
If getting a title for a tractor is possible in your state, you still may not wish to do so.
I had similar concerns back when I got my first tractor, and posted a question about it here. TBN members convinced me that there was little to gain by getting a title, but much to lose possibly. I foget the details, but there were issues like possible need for a license plate if the titled tractor was run on a road, insurance issues, and so on.
After hearing all the arguments against getting a title, I wrote that idea off pretty fast.
