What a piece of China garbage. Seller claims usa made. Package clearly says china. Blade wobbles and cuts aweful. Blade had no sticker on it like in the picture. Bad product dont buy.

    Didn't realize how the lawn should look. One side of the old blade was bent down. Don't remember hitting anything, but this blade is an exact match and the grass cuts faster and more evenly.

    Reviewed in the United States on June 16, 2025
    Verified Purchase
    I'll be honest, I didn't read the description, or any reviews, I just went on 鶹 and bought the first replacement blade I found that fits my lawnmower. I've replaced the blade before from the big box store with the brand name, I've sharpened it several times and it had finally had it.
    I was pleasantly surprised that this blade was made in the USA (again, I did not read the description) and also found that the curve was greater than the stock blade.
    Upon installing the blade on my lawnmower and proceeding to cut the lawn, I noticed that the blade was creating more of a vacuum and actually sucking the grass up under the mower deck, pulling the grass straight up.
    This has been by far the best cut I've ever done with this lawnmower, I am so far one cut in with this blade, perhaps I'll update at the end of the season.
    I couldn't possibly recommend this mulching blade enough!

    5.0 out of 5 stars Perfect replacement for my old craftsman mower.
    Reviewed in the United States on June 16, 2025
    Verified Purchase
    This blade was just what I needed. This new blade was an easy and inexpensive fix for my mower. My several years old craftsman was vibrating almost uncontrollably. I looked online for a fix and I found that sharpening or replacing with a new blade would help. The new blade made my lawnmower, usable, and like new. It’s easy to replace. The photos in my review are the before picture for reference. There is only big bolt to unscrew, and a metal spacer, to lock it in place. Great purchase!
