Bolt broke in shaft

Drilled out broken screw, and used an easy out to remove it. Removed the blade adapter by tapping on it. I then install the new one by lining up the key inside of it with the key slot on the engine shaft. And I tapped it on. I then attached the blade to the adapter with blade support. And the blade bolt and tightened it into the shaft. Works great now.

5. Replace the blade adapter, the blade, and the bolt. BE SURE TO TIGHTEN THE BOLT SO THE BLADE DOES NOT COME OFF! You may need to wedge a piece of wood between the blade and the mower deck to keep the blade from rotating while tightening the bolt.
