I have a JD diamond tool bar carrying my 71 flex planters. I run two sweeps on the outside of the planters that serve as row markers and do a decent job of cleaning up between the rows. I hung one last season on a big oak root in the dove field and broke the cast iron clamp. I got it welded and it ran several acres before giving up again this year. Its not the end of the world, but I'd like to find another clamp. Reckon this is something I have to source through JD, or would there be a better resource? Honestly, If I could find a third clamp/shaft/sweep to run between the rows, that would be a bonus, as well. It does a good job of buying time with the bermuda grass for me.
