restoring a disk harrow

[Rapier]

GOB,
If you cut that tree right, you should be able to 3 pt hook up to the disk and raise it up enough to drive off. First cut the tree off at the top of the frame, 3 pt hook up the disk, raise them up as high as you can, block disk up, then cut under the disk, the disk set should be free of the stump. If you have a front end loader on the tractor just chain up the disk and lift off the stump after the first cut. I would not burn the stump with the disk in place as you will do more damage than you can fix in a month of Sundays.

Oh, if the tree has grown up between the blades and is stuck, before you try to raise the disk, take the chain saw and plunge cut the stump down the center from the top. This will allow the sides of the stump to flex inward and set the blades free when you lift the disk.

I think once you get it free of the tree, you will find that it still works. A set of disks is a very tough piece of equipment and as long as the disks turn on their axles, even if you must run them to get them to turn, greese her up and go to town. Seven years is not a back breaker for a set of disks. Up near my farm I see old sets of disks used all around the place, all have a very old 100% "brown patina."

If you need pieces and parts try Tractor Supply or go to Tractorbynet.com their forum is full of guys with tractors, tractor problems and suppliers resources.
Best,
