Marty, first things first. What tractor, what year, 6 volt or 12 volt, how long has it been sitting, did it run when park, did it ever turn for you, do you know its history??
Is the hood on it, have you had the head off, when is the last time it ran etc.
First thing I would do is put some MMO in the cylinders and get a big wrench to turn on the front main pulley bolt. Then I would let it set for a few days. Some folks also use ATF. MMO= Marvel Mystery Oil. ATF automatic trans fluid.
After a few days or a week, I would work back and forth on the front bolt to try and turn the engine back and forth just a little. Once you get it to move, you just work it a little bit at a time back and forth till it gets loose. Then you turn it forward till you feel resistance again and then work it back and forth till it gets loose.
There may be a how to in the How to section. I will look and post back.
