If you want to improve the performance look into getting a AFX rotor with the spiral front or get the afermarket version from Stewart Steel in Alberta. Also check at left side of this page for "attachments." Our host, Marvin Gordon has rub bars and a new style chaffer that will help too. For wear check everything the grain touches on its way through the rotor cage, like elephant ears, vanes, rub bars, concaves and all the augers.
