Stuck, missing, tad smarter

Neighbor donated an old JD 8' wheel disk to my collection of old iron. Just come and get it. Went over and found that one wheel is missing and he left it where he stoped. That is with the disk still in the ground. He wants me to get it while the ground is frozen (very wet ground), so I don't tear up his yard. How the He!! do ya get one up thats frozen in. We took the AC over and proceeded to stress test the boom pole. (it failed), stress tested a few chains (they passed but the boy learned how to get the front of the tractor off the ground). Any thought on how to move this disk?

Unrelated - Does any one know the lenght of a tonge (wood) for a old NI hay rake? I have all the metal parts and just need to cut a new tonge for it

I had an S-tine cultivator with straight points, none of points were in soil as far as bolt holding point. Hitched tractor, I could have lifted and pulled it out. It wouldn't have been worth five cents when out. It stayed there until spring.

Jack hammer. Hope you know someone with a portable unit that owes you a favor. Rental places have them.

If you live in a climate where it thaws & freezes, wait until it thaws, jack it up with a lot of wood under, & then move it when it freezes early one morning.

If it is only lightly sitting in the dirt, you could get a jack under each shaft, put some serious up pressure on the shaft, and bang around on the frozen dirt with some pry bars. But this is serious work, & I don't think you'll get there if it is sunk in to the shaft as I am guessing.

Pulling on it at all will only give you scrap iron or seriously hurt people when the chain breaks or the tractor flips over, please give up on that idea. You need upward pressure, not pulling forward, that won't do it.

You need to to break little bits of it loose at a time, one blade at a time, pry upwards on one end of one gang. Don't pull forward or to either side. Pulling backwards a bit might help, but not if it's really sunk in. You want the pressure upwards.
