First off, if you are intending to save this thing and get it running again, STOP, back up, and take it easy, I've never "heard" the word "BEAT" some many times in regard to trying to save/repair something!
What, exactly, are you trying to do, do you have the engine out of the tractor and torn down to the point the crankshaft can be removed?
If so, AND you can get the rod cap bolts ALL out and caps off you can remove the crankshaft, then deal with each stuck piston individually.
Remember that the rod and main caps need to be marked (if they aren't already) so they can be put back EXACTLY as they were.
If NOT, for every piston you BEAT on, anther one has to go down, as well, and two have to go up, doesn't work real well and puts a lot of stress on parts not made to be treated like that!
I HAVE done as Jim suggested and drilled holes in stuck pistons to the point they are in pieces and can be removed, at this point the engine needs new pistons and sleeves, so nothing is lost by doing that.
Once you DO get it apart, install the rod caps correctly and take the rods to an automotive machine shop and have them professionally check for "straightness" and "twist", have the "big end "sized" and new bushings fitted in the "small" ends and resized to fit the wrist pins in your new pistons.
The crank should be checked out, as well.
Nothing worse than doing a partial job and buying $$$ parts only to have the job fail.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
