I pressure washed them, then sprayed them with polyurethane to seal away the rust. I like the LOOK of rust, but I don't really like the idea of having rusty things around me. Maybe it's because I don't like the feeling of needing a tetanus shot to walk around my house.
So what do you think? Would you hang tractor blades on your wall??? It's ok, you can say "hell no" if you want too.
