I had mowed over a garden tool so I had to replace iy.
First I got the wrong blade off of Amazon then I researched and found your website and I wrote the blade number so I can get the right one. It was a curvy blade and it was right size but it did not have the two holes on the side. How I replaced the blade is I flipped the lawnmower over and took the other blade off with some kind of pliers. Then I put the new blade face down to the ground and tightened it. Then I turned the lawnmower to the ground and cranked it and it worked. It was a great fit. Thanks
