Abstract
A cushion standard shield system to remove and deflect residue, dirt, debris, and soil from a cushion bearing hanger, or cushion standard, portion of a disk gang type agricultural implement is provided. The cushion standard shield system includes a mounting bracket supported by a common axle which carries multiple disk blades of the disk gang. A blade assembly is mounted to an upright portion of the mounting bracket, and is positioned generally behind and above the axle, behind the cushion standard. The blade assembly includes one or more plate member with arcuate lateral edges. The radii of the arcuate lateral edges correspond closely in magnitude to the radii of the concave and convex surfaces of the disk blades. The plate members are laterally adjustable with respect to each other, whereby the width dimension of blade assembly is variable to accommodate different axial spacing widths of adjacent disk blades.
