Too many Kubotas

There's no reason to worry about keeping diesel fresh. At least not for the first 10 years after buying it. Keep the tank(s) free of water and there's no risk for bacteria, and/or treat the fuel accordingly.FWIW: The tractor uses 5-20 gallons a month, currently fed out of 5 gallon jerry cans, but I would like to have closer to 50 gallons on site for winter storms. I don't really want too much more, because I know I can't keep it turned over and fresh.
When in CA I was about to use an old propane tank to store fuel in, since nobody pays attention to those. Also considered keeping it in a water buffalo, but with my luck the fire department would hook up to it if I wasn't there. Ended up fleeing the state instead.
Here I started with jerry cans, which was a pain. Literally. Bought one Lee Agra 200-gallon tank, liked it a lot and got a second one for gasoline. Then four 325-gallon plastic totes to replenish the Lee Agra tanks with, and two of them have their own pumps, but not batteries and solar panels.
For the generator I use a small covered trailer with a 135-gallon tank, back it up to the generator as needed and let gravity do its thing.
All fuel is being delivered, which saves both time and money. I think the minimum is 300 gallons, but tend to exceed that by at least 1,000 when having a delivery about every two years.
