18 in. Replacement Mower Blade is rated 4.0 out of 5 by 7.
Rated 4 out of 5 by from Good all purpose replacement Seems to fit alright, but as it is designed ti fit more than 1 product, the hole for the center bolt was a bit big. I managed to get it tightened down properly after several tries and it seems to work just fine. Please, in the future, put a list of replacement part numbers in the owner's manuel. It took some guessing to find the right blade as the numbers were totoally worn off my original.

Rated 1 out of 5 by from Didn't fit correctly The replacement blade was the correct length but the hole in the center was slightly bigger than the electric motor shaft so it caused a loud hum and lots of vibration when the motor was running. Home Depot very kindly accepted one of the blades at our local store but the second blade was on the mower when I traded it in on a new mower at the Black & Decker factory store.

Rated 5 out of 5 by from Got a hard to find part. Factory replacement part fit perfectly, and was easy to install. Ordering it was easy and only took about a week. Local stores did not even stock this part.

Rated 5 out of 5 by from The replacement blades are hard to find. Great blades- easy to install The blades for the Black and Decker electric lawnmower are of very high quality and a very good quality. I change the blade every 2 years to maintain and promote a healthy lawn. This ensures that the grass is getting cut properly and not just whipped around by a dull blade. I hope you continue to sell Black and Decker products, especially lawnmowers.
