My mama always said I ain't stupid - I just ain't none too smart. Figured I better get that out of the way first. So, on to my question. What really is the purpose of the A arm guards on the atv's? I've always had to spend extra time trying to flush out the mud and gunk that collect in them. When I bought tracks for my machine (winter use only), I had to take them off. Switching back to the tires, I decided to leave them off. Cleaning has been much easier now. That wet gunk doesn't sit against the metal, so it seems like it should help prevent rusting. What am I missing?
