I know this is a commercial lawncare forum, but this is the only place I could find that had anything to say about how to remove the blade from a push lawnmower. I posted this question to another thread, but it's buried as the 53rd post. I thought I'd have better luck if I started a new thread. I apologize for my rank amatuer status. How do I remove the blade from my push lawnmower? The bolt won't budge, and I'm embarrassed to say that I don't even know which way I should try to turn it.
