I have subsoiler mounted on a solid two inch square toolbar. I'd like to find a pair of 16" disks that can be switched out with the subsoiler to make a garden row-hiller but I am having trouble finding a supplier that sells what I need. On my tool-bar the bar is mounted to the 3-point with the corners vertical/horizontal (or... looks like a diamond viewed from the end. All the disk-hiller mounts found for sale to date have the bar mounted to the 3-point with the bar flats parallel to the ground. I have found pictures of tool bars mounted like mine but not enough info to track down parts. Just having the name of a mfg. that makes a tool-bar with the bar mounted like mine would help.
