A week ago I took the blades off & sharpened them. I used an impact wrench & my son wanted to help. He wanted to put them back on. He took the blade, put it on, then the washer & started the nut on all & then tightened them. I then mowed the yard. The whole time thinking to myself that it wasn't cutting very well. I then took the deck off again & took one of the blades off to try to find a match locally. Fast forward a week when I go to put the blade back on. I notice that the other two do not match orientation of the one I just put on. in my dad role watching my son use the impact wrench, making sure he didn't get hurt, I didn't realize that all the blades were on upside down. So the blade was hitting the grass on the blunt side, not the nice sharpened edge I just created. It mows much better on the sharp side.
