I have this cheap bilt hard push mower. I bought it last year to cut around trees and run over sticks etc, anything to save my riding mower from getting damaged. Well the other day I bent the blade and the blade adapter. This is what I bought it for but am unable to find a replacement. Can anyone suggest an adapter and blade I can put on this shaft? Is there a universal one out there or something that might work? I bought a few adapters from Amazon to try out but they seem a little shorter than the original
