The Underside is Broken

This is what the underside of my lawn mower looks like.

I'm pretty sure this blade isn't the right shape either. 

It's unfortunate that I'm looking at the underside of the mower, but I had to do it to identify what was broken (besides the blade).

It was one of those jobs where the more you looked, the more broken stuff you found.  By the time the ordered parts arrive and I get them installed the grass will be tall enough to get all the new parts broken in properly.  Just not too broken in I hope.
