Hey.. if you are afraid to run your tractor, then it's time to sell it!
Is your tractor such a POS that it won't do an honest days work? time to sell it.
Real working farms and jobs run machines all day. you do maintenance, you do repairs as needed. It's the price of admission.
As for running 12 hours a day? If that is in power generation... someone may not be using their resources correctly in an emergency.
Lighting and small loads can be run off a good inverter and battery. LED lighting is very available now and is a fraction of the electrical load of incandescent.
I'm doing a test with a usb power pack. 4000mah and it has a led flashlight. flashlight has been running continously for over 2 weeks now. it's dim, and I expect it to drop out this third week, but it is making useable light.
I don't even own a standard flashlight anymore.
Inverters in the 1-2k range are now affordable.
microwaves int he 700w range are the most common.
Should disaster planning include watching tv and microwaving snacks, running the ac, watching tv while all of your finite resources get absorbed ina couple days? People planning like this have not been thru an outtage that lasted weeks. when florida was hit in 04/05, parts were without useable infrastructure for 3 weeks. no gas, no diesel, no power. so don't run your genny 24/7 use it like it's emergency backup...
