Heavy duty Break Away Release Bar For Kuhn, Fort, New Idea, Or M&W Disc Mowers. Most all have "Ball End" mounts on both ends of the bar. See pictures for one that matches yours. I can send you dimensions for any one pictured. The price is the same for any one of the break away bars.
All are in very good working condition.
Message me before you purchase so I can confirm the one you want is still available.
See my other listings for additional disc mower parts.
