This left-side tine mounts on the rotary harrow to engage and fracture the soil ahead of the following consolidation roller. It is the primary working element that transfers the tractor's drawbar pull into the seedbed preparation process. A worn or broken tine reduces working depth unevenly, leaving unprocessed strips that compromise seedbed uniformity. The original geometry matches the mounting bracket's bolt pattern and the tine's rake angle, so no shimming or adjustment is needed during replacement. When installing, torque the retaining bolt to the specification for the harrow frame.
