Gator blades for B7100

[grossgary]

I searched but didn't find anyone using gator blades on a B7100. Maybe they rob too much power!?

I'm looking for new gator blades for my 60" MMM on my B7100. I've never bought a lawn mower blade before, so I imagine this is a stupid question. The online information is vague and seems to only be useful for ordering by measurements. Where do I start looking?
