My lawn mower blade wouldn’t stay in place. The old blade adapter had worn down and broken.

Very Easy

Socket set

I took off the old blade adapter and put the new one on. It literally requires removing one bolt. Unfortunately, once I started and ran my mower for a few minutes it blew up and left a charred patch of lawn. The underside of the mower is mangled metal and unusable now. The repair, though, was super easy!
