Off of there website I bought 3 adapters and 3 ripper blades for $73.99.
My blades on the Bad Boy are still good and only been sharpened once.
I put the ripper (mulch) blades on the top like I saw on a bunch of YouTube
videos. I cut part of my yard after I put them on yesterday. It was still a little
wet and high like everyone's right now, but I could see the difference. Shavings
were a lot smaller and it shot the grass way further than before. I was very
pleased with my first cut.
