Comments about Arnold® 21in Dethatching Blade (490-100-0056):
The blade was sharp from the box. Multiple washers and addapters to fit most lawn mowers. It is a 21 inch, so it does fit a 22, but a little of the vaccuum power is lost with the 1/2 inch gap between the end of the blade and the mower deck.
