Got it free, check my post.
Thanks, all for the advice, all of it useful.
There are threads in the forum that describe how to kill yourself while freeing the clutch....most involve chaining the tractor to an immovable object, starting it in gear, holding the clutch down, and letting the chain come up short.
If the clutch does not disengage, the tractor will flip and crush you. End of clutch problem for you.
