NEVER, EVER pull a tractor to free up a stuck engine. I bought an F-30 that someone did that to, and the #2 connecting rod looked like a pretzel. I finally sold that F-30 to someone for parts, and bought another one in better shape. Luckily, I broke even on that one.
Everyone has given very solid advice. Try the oil in the cylinders (ATF, PB blaster, Kroil, even diesel) and let it sit for a few days, a week or two is better.
Patience is an absolute necessity in freeing up a stuck engine, unless you are going to tear it down, or minimally take the head off. My Regular was dry-stuck, and I used PB Blaster in the plug holes. Let it sit for 2 weeks, then took the clutch cover and clutch off (it was junk with mouse nests anyway), and made up a bar that bolted to the fly wheel. Put a 4' piece of pipe on the bar, and in less than an hour, I had it freed up. I also look inside the cylinders through the plug holes with a bore light, and they were pretty clean, just a ring of slight rust where the pistons had been sitting for years.
good luck, but for the love of God, DO NOT PULL IT to beak it free.
