"Crack a line" is a slang term for loosening one of the connections to see if hydraulic oil is present in the line. This is VERY dangerous to do with the hydraulic system under pressure.

Hydraulic oil freezes at several hundred degrees below zero. No, it could not have frozen up unless there is a lot of water in the hydraulic oil, and then it wouldn't have frozen up in the middle of a job.

The most likely cause of your problem is a bad hydraulic pump. They usually get weaker and weaker over time, but it's not unheard of to have the pump simply quit altogether.

I am pretty sure that the power steering and 3pt hitch are controlled by a separate hydraulic pump on that tractor.

The best thing you can do right now is hire a professional mechanic to come over and check your hydraulic system for pressure, and have it "flow rated." Otherwise, you are just guessing.
