I have never seen diesel fuel gel before, until tonight. That tractor is not moving.
The stuff you put in the tank will get it thawed, but, it won’t happen immediately. Do make sure you use the winter blend diesel, but, you will probably have trouble anyway when it is this cold.
I wish that global warming would kick in.
Best,

Lol, don't try to start it, till it warms up a bit and everything thaws. You're probably going to be freezing arse tinkering, and might make it worse. The tank and lines will probably keep gelling anyway, even if it fires up. This is what #1 diesel is for, but it still might be a hard starter, if it's never been there before. Maybe having a can of starter in the tool bin, wouldn't be a bad idea, if this tractor does emergency work.
