Another thought could also be, try bolting or hooking a chain in one of the holes trying to spin it free that way.
Also with the chunk lodged up in there, it might be very difficult to unbolt and remove the blade. It could possibly lead to damage.
And another thought, could the gearbox be loosened without removing the blade? If so, that might give enough play to spin it out.
Good luck and let us know how you fixed it.
