Yeah, cut quality sucks for sure. Cutting height looks a bit high for what I'd call a scruffy lawn. You don't get as much suction on a lawn like that as you would on a full/lush lawn. The grass on a full lawn seals around the deck giving better suction. I find myself cutting crappy lawns in the 2.5 to 3 inch range whereas I'm at 3 to 4 inches on my nicer lawns.
You're sure the blades aren't upside down? Can you sneak a picture under your deck? Not trying to insult your intelligence but something definitely isn't right.
How is that an insult? I change my blades all the time and still put them on upside down every once in awhile.
