I started tractoring with an 80's Kubota
B8200 about 14 years ago. I sold it after 10 years for about what I had in it. It was a trouble free, hassle free machine. I wanted a bigger tractor, a SSQA loader, and HST vs. gear. I assume it is still working for the guys who bought it. The
L2250 was a contemporary machine- '85 - '90. If you contact Kubota with the S/N, they can tell you when it was built.
For the money, it might be a fine tractor. Check for deteriorated hydraulic hoses, cracked rubber on the tires, and if the oils and coolant look like they've been changed and clean, you should be good. New hoses aren't too bad, but tires aren't cheap. Minor tire issues can usually be fixed with tubes if the rubber itself isn't cracked and chunking. It might need a battery, but other than that, they last and last. Make sure the PTO and loader work as intended, and driving/shifting seems okay. It should pull a 60" rear brush cutter, and heck, clean it up, use it for a couple years, and sell it for what you paid when you get the tractor bug more seriously.
