This nut secures a cultivator tine or other tillage component to its mounting point on the machine frame. It threads onto the corresponding stud or bolt to clamp the component in place against vibration and operational loads. A loose or missing nut allows the tine to shift, which alters working depth and can damage the mounting bracket. The manufacturer produces this nut to the same thread specification as the original assembly, so it engages fully without cross-threading. On reinstallation, tighten the nut to the torque value specified for the application.
