Hi sorry for the delay in answering, what I did was use a blade from B and Q that had the same hole layout, I had to cut a inch off either end, then balanced it, it now runs perfect, I now know to check blade before starting a second hand mower ( pull plug just in case ) also if it's viberating it more than likely the blade, Yes!! I did learn a lessen could of been the hard way
