Are you speaking of the driven pulley on the bottom of the gear box? If so then I've had that issue myself. The bottom pulley works in dirt and the lower edge gets sharp from wear. I've pondered having the edge welded/brazed and built up. I haven't done it because I had a spare but I don't see why this wouldn't/couldn't be a fix. I think those pulleys are expensive too. I've never had any issues with the upper pulley of the gear box.
