What do I need to do to remove the blade adapter assembly for replacement?
ANSWER : You can remove it with a flywheel puller. I would use the one that has the flat hooks at the bottom of the puller. I would also use the blade bolt to push against with the flywheel puller. If you hook the flywheel puller onto the crankshaft there is a possibility that you could damage the threads for the blade bolt.

I hope this helps you out.
