This shield covers the tine bar of a cultivator, preventing soil and debris from wrapping around the rotating components. It is mounted directly over the tine bar assembly, where it deflects material that would otherwise accumulate and cause the tine to lift or stall. A missing or damaged shield allows crop residue to build up on the bar, leading to uneven working depth and increased draft load. The part is formed to match the original profile of the tine bar, so it fits without modification and maintains the clearance needed for the tine to pivot freely.
