Replacement blades all came off
I gave my X7 a little bath today cuz it was all dusty and muddy and noticed that the three blades I replaced on one cutting wheel for all gone now. They seemed to tighten and be secure when I did them but they're all gone. I have a bunch more from what I ordered on Amazon but I'm not sure if it's worth leaving sharp pieces of metal all around my yard if they're going to keep falling off.
Ideas?
