Claim:
A cushion standard shield system for use with a cushion standard of a disk harrow, the disk harrow including first and second laterally spaced disk blades carried by an axle extending along a first axis, each of the first and second disk blades having opposing concave and convex surfaces, comprising: a mounting bracket having an elongated, planar, horizontal leg portion with a lower surface and an upright bracket extending upwardly from said horizontal portion; said attached to a lower portion of the cushion standard; a blade assembly having a first plate member and a second plate member: said first plate member having upper slots aligned with lower slots attached to the mounting bracket and extending between the first disk blade and the second disk blade, the first plate member has a concave lateral edge and a convex lateral edge; and said second plate member having upper slots aligned with lower slots operatively connected to the first plate member and extending between the first disk blade and the second disk blade, the second plate member has a concave lateral edge and a convex lateral edge; a bearing assembly having an upper horizontal flange wherein said lower surface of horizontal leg portion interfaces with said upper horizontal flange of said bearing assembly; said upright bracket includes vertically oriented elongated slots wherein the blade assembly slideably moves upwardly from or downwardly toward the horizontal leg portion of said mounting bracket; wherein: the convex lateral edge of the first plate member is proximate the concave surface of the first disk blade, and the concave lateral edge of the second plate member is proximate the convex surface of the second disk blade; the first and second plate members are movable along a second axis generally parallel to the first axis for adjusting positions of the first and second plate members with respect to the first and second disk blades; wherein first and second plate members form a shield to block soil residue completely from approaching said cushion standard; and said shield is behind said axle and angled rearwardly approximately 15-25° from a vertical plane from said disk harrow.
