Ah nuts. I was hoping to use it to maintain my whole lawn, except near the house. I'll have to check again, but I don't recall having that many knives. I've only bought and brought it home, it's still sitting on the trailer as I have many other things on my plate at the moment. Main reason I got it was to maintain my field, which it will work well for I'm sure. An added bonus would be to use it on the whole lawn. I'd think a rough cut model wouldn't have scoop knives on it, but all that can be changed pretty easily so perhaps someone did before I bought it.
