Blade works fine as does edger which is 10 years old. Issue came from labeling on the package which stated 'to be used ONLY for model...' which was not the one I owned. Checking with the store computer IT stated that the blade was correct for my machine! My research on PartsDirect.com agreed so I purchased it, matched the sizes, and installed blade. Check with knowledgeable sale person and/or verify with PartsDirect before purchasing.
Blade doesn't work for long. Blade should be $5.
