This guide bar is the left-side component that mounts on the tillage unit frame to guide the movement of the attached implement or linkage. It works in conjunction with the right-side counterpart to maintain alignment and control lateral travel during operation. The bar is subject to bending or wear at the mounting holes and contact edges over time, which can cause misalignment and uneven implement tracking. As an original part, it is formed to the same hole spacing and profile as the factory assembly, so no drilling or modification is needed during replacement. When installing, use the original hardware and tighten to the specified torque.
