One of my tractor concerns is that 15 years from now, one of the circuit boards on my 2003 "new-fangled" tractor is going to burn out or fail from vibration fatigue. Will Kubota still stock them? Computer controlled machine makers are famous for not supporting their electronics after a certain time. Hope the tractor manufacturers are better.
Break out the soldering iron and fix the burnt one for a spare. You can still read the resistor values so it didn't burn too bad!
Maybe I'm being a little facetious. The bottom is burned pretty good.
