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.

Hart 21" SP Brushless Mower ~ Variable Speed
After owning gas powered lawn equipment my entire life, with my wifes encouragement/urging lol, I decided to give a battery powered Mower a try. We purchased the Hart 21"Brushless SP W/Variable Speed Mower last July, I have to say, I didn't have the confidence it was the right decision for us, here are just a few of my reservations.....would the batteries last long enough to mow the entire yard, it isn't very heavy: is it sturdy enough, will it fall apart, if stored properly, will the batteries work after a year, how hard is it to get replacement parts etc. but, wow was I wrong! We both love it! It has done a fantastic job for us, I'm now purchasing a replacement blade for it! Highly Recommend~Hart Lawn Equipment

Exact replacement
Perfect replacement boade for my 21 inch self propelled lawn mower. You need a 11/12 sized wrench to change it. Its not included in the package.
