Be glad to Mike. 

But first I want to mention some of the comments about patience. I've never had a tractor that begs to be "snuck up on". This is clearly a tractor that deserves to have a chance to be freed with the least amount of tool marks, grease removal, and parts replacement. If I can get this tractor running well without any disassembly or noticeable "technician marks", this is it.  I feel certain, based on what I've seen, that I can get this tractor freed and running. If it doesn't run to my satisfaction then I will tear it down. But I think I can get it to run well without tearing it apart.

What I have tried:
1: I shot it a couple of birds. This did not work
2: I drink a couple beers and stared at it. This did not work.
3: I soaked it for three months in a variety of different penetrating fluids.
4:: I raised one wheel, put it in fifth gear, and tried to apply force to the raised wheel while the other wheel was  on the ground and chocked. This did not work.
5: I tried raising the entire rear of the tractor with chains on the rear wheels and 5th gear.  Nothing.
6:: I tried refrigerant. This seemed promising, but did not do anything in the long run.
7: I tried a hydraulic jack  on the counterweight of the crankshaft. But the front end of the tractor is  the light and I feel sure I'm not putting much pressure on it. 
8:  I have tried putting air pressure on the cylinder to try to drive the penetrate down.
9:  Rapping the piston with a brass bar during all of these

To do:

1:  air pressure:  I am having still a little too much trouble with air pressure leakage through the valves. So I am closing off the exhaust manifold and the intake manifold with some bar stock and gasket material.  I have yet to finish this, as the exhaust flange was a real bear to get off of the exhaust manifold. I just got that off tonight. Hopefully within a day or three I will have that finished. Then I should be able to apply plenty of pressure to the cylinder.
2:  Create an opposing force for the hydraulic jack on the counter weight on front cylinder. I will be fabricating a frame that  mount to the cultivator bolts. This will allow the jack to push against something other than gravity.  This should be easy, but I am cheap. Channel iron, anchors and eye bolts are expensive.  So I'm trying to find something that I can fabricate, or buy, that will allow me to inexpensively build some sort of a frame or chain sling to mount the hydraulic jack on top of.  Still researching this.
3:  Additional hyper cooling. I may still try the dry ice and alcohol method.
4:  A penetrate that works on the aluminum oxide in the galvanic corrosion. There are a few compounds that do this. I got one from Brice Adams who got it from a chemist at the university he works at(methyl salicylate). If I try any type of solution, this will be it. But it seems like black magic. So I'm going to leave this for later.

Things I have ruled out:

1: Pulling it. If I can't get it to free with methods I've tried,  I'll just leave rubber on the road.
2:  Rust removal solutions. I may try this yet, but the compounds I have looked at I doubt will do anything, as I believe galvanic corrosion between the aluminum and iron is my main problem.

As usual, keep the ideas coming!
