Installing grass blades on a Betstco flail mower

I have a Betstco EFG135 with 24 blade sets. I swapped my mulching hammers with a set of grass blades for the mowing season. This is a fast walk through how I did it and what you'll see lying on your back under the flail. Some large dents in a few mulching hammers that I'll have to pound out. That's why I won't run the grass blades in the woods.
