The 580s are much more popular and most 590s are owner operator type machines. So they don't make their way to auctions very often. Most are traded in. I am sure you BH does not have a turbo. If it did it would be a Super L. No AC and No turbo will make it harder to resale. The good news is since the machine came from an electrical coop it likely has never dug more than 4 feet deep and had light duty backfilling duties (this is why utilities seldom get the full boat Super L's or M's they don't need the added capacity (I am surprised it had an extenda hoe most don't need that either). You likely wont either if its just for you to play with and not a production type machine. Just know that it will be harder to sell or you will have to discount it more heavily. I would try and find a Series 2 Super L. Better machine and easy to flip. But you will likely have to give more for it so perhaps it would not pencil out for you.
