Seems like we go through these quite often. My husband has a gift of mowing over rocks an very large rocks. Even the best blades can't handle hitting huge rocks. For the money, these are very good quality.
Have simply removed/sharpened old blade since getting mower a few years ago! Best to have a second one; helpful clerk helped me know I had correct one at Coshocton store.
My lawnmower blade hit a rock, So, I took the mower apart, purchased the blade. It was easy to replace it at Sears!
My mower came with a damaged blade. It was tearing my grass to shreds and was making the tops of the grass turn brown. I decided to replace the blade with this one and was very happy when it actually cut the grass nice. My lawn looks nice and green now.
I bought this as a replacement for my 22" Toro. I have cut the grass twice so far after replacing the blade, and it is doing an excellent job mulching the clippings.
This item was just what I needed. My grass got a clean cut that will help it stay healthy.
