A perfect replacement part
My old part was rusted and the threads were in bad shape. The new part restored the integrity of my blade.

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.

Everything went well. Had to use a puller to remove blade adapter. Then lined up the internal key in the blade adapter with the key way in the engine shaft and tapped it on. Put the new blade on and tighten it up with the new blade bolt.

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.
