I believe they are factory standard blades with less to noi lift. And on that particular house I was the highest setting, 4.5 because of how long it was. Unfortunately, copperhead doesn't make blades that fit my mower. I'm finding it difficult to find blades for it. I have the Ikon XD 42
I would try and find a Ariens dealer and see what blades they can get...Unfortunately a lot problem is it's a residential mower , you're not gonna get a cut like you would from a commercial mower. My uncle has a residential toro ,it's the same way.
