A bearing shield and disk scraper system to remove and deflect dirt, debris, and soil from a bearing assembly, rigid bearing hanger or standard, and/or disk blade, is provided; the system also provides a protective barrier structure for the bearing assembly. The bearing shield and disk scraper system includes a shield member and a scraper blade connected thereto. The bearing shield at least partially encases and protects a bearing assembly that rotatably supports a common axle which carries multiple disk blades of the disk gang. The scraper blade is attached to the shield member by way of a mounting flange that extends therefrom. An edge of the scraper blade is positioned in close proximity to a concave surface of an adjacent disk blade, whereby the entire assemblage of bearing shield and disk scraper system protects the bearing assembly and prevents non-desired accumulation of dirt and debris on the disk blade.
