replacement blade for B&D mm525 mower
I was given a black&decker electrical mower (mm525, type 4). It's missing the blade. I am trying to figure out what replacement blades are compatible. I am cheap so I don't want to buys a blade, instead I want to find a broken mower and cannibalize it. So it it just the length and the size and shape of the whole in the center that determine compatibility?
