These craftsman blades fit perfectly. Never have to guess about it when I go to Sears because they always know which blades I need. And the cut great. Our yard looks good all summer. They don't leave gaps like some other blades do. You can't go wrong with Sears or Craftsman products.
I don't know many of these blades I've gone through. They bent first time they hit anything larger than a blade of grass. The last rider I had I only sharpened blades, these never get dull, they don't last long enough.
The add said it fit all 42 inch deck . It does not .
It was so easy to put on using my Craftsman impact tools that I'd purchased earlier.
