You'll be shocked by how much thatch and moss this blade takes out of your lawn, I was! Be careful though, if your lawn is uneven, in places it will take out more than just the moss, i.e. EVERYTHING, grass included. I've been left with quite a few big bald patches on my lawn now. That's the price you pay for power assistance, but then I'd rather a few bald patches than doing it all by hand.
