Hmmm, lets see, I removed a worn mower blade from my mower, and installed a new mower blade onto my mower, and low and behold, it cut the grass. Other than the ridiculous amount of time it took to receive the mower blades through the silly and slow ordering process, all went well. Would have been MUCH easier if the SEARS store was still available here in town! I would not recommend this item to any of my friends as none of them have this particular lawn mower!! Really a stupid question ... Would I recommend this product to a friend? Seriously??
