Rigid Standard Bearing Shield Disk Scraper System
First Claim
1. A bearing shield and disk scraper system for use with a rigid standard of a disk harrow having a disk blade carrying axle that is rotatably supported by a bearing assembly, comprising:
- a bearing shield including a bottom wall and a sidewall, the sidewall of the bearing shield being attached to the bearing assembly such that the bearing shield member covers at least a portion of the bearing assembly;
a mounting flange connected to and extending rearwardly from the bearing shield member; and
a scraper blade removably attached to the mounting flange and interfacing a surface of a disk blade.

Abstract
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.
