Exact Replacement

Exactly the same as original equipment. The picture looked exactly like the original blade on the mower. Not like the old days in which the mower came with an owner's manual with part numbers for nearly every part. The picture was helpful, and I was lucky, when I received it,it looks and feels exactly like the original. Along with annual sharpening,we should be set for about six years.

easy swap!

This blade fit the 21" supercharged self propelled Hart mower. Took a bit of research to figure out which of the 2 available Hart replacement blades was the one. Very easy to change for a 63 yr. old female.

Double check compatabilty!

Difficult to work out which blades are the replacements for these lawn mowers because they seem to be difficult depending on your lawn mower model number despite being the same length. So definitely triple check your model is compatible before ordering and dont just look at the inches of your lawn mower. Otherwise fantastic blade and great lawn mower all round.
