Got my mower last week and am looking for material to address same issue. To Hoss45, is the guard you put on made of dense rubber, if not I'm thinking it will not last long. Is it adhesive backed? To Beytill, I like your idea, wish I knew where I could find a couple thick pieces of conveyor belt or dense rubber. Wish I still had the old non-radial tire I threw away, might have been able to cut a piece off of it.
