For soaking a stuck engine, I like to use automatic transmission fluid (ATF). Everybody you talk to will tell you something different such as PB Blaster, deisel fuel, or a mixture of this and that. Your tractor has removeable cylinder walls (sleeves), that can be pushed upwards and out the top of block. If the sleeves just have surface rust, they could probably be hoaned and so forth and used again. If the sleeves are rust pitted, they are like damaged to bad to be used again. I had a single piston on an F-20 froze so bad that I had to resort to the wood block and alot of pounding to get it out. Never use metal to metal contact (always use a peice of wood to beat on) and never use an excessive force that will cause the object part you are beating on to break when you resort to the pounding method. In my case, I broke the sleeve which was rust pitted beyond use anyways (the piston cocked side ways on that last pound and broke a chunk out of the bottom of sleeve). If more than one cylinder appears to need excessive force you might wish to remove any pistons that are not froze, then remove all but one that is badly froze and more than likely you will want to use downward force to start with to free it. If you chose to replace sleeves and pistons, remove sleeve and piston together by removing out the top of block, ounce it is out you could always crack the sleeve off the piston to get the rod if you don't want the piston either.
