Driving around the 1939 John Deere A after doing some work on it throughout the winter. We replaced the radiator core, muffler, and rebuilt carburator. This is the same tractor that I made the time lapse video reassembly of.  It’s amazing how much work you end up doing any time you decide to tear down into one of these things.  You go to fix one thing, and find that there are two more things that need to fix.
