I could use a set of used, 
“RedE” Vertical Till Coulters.
I just want to cut out the center with a water jet, to use as a spacer.
50 of them is what I need.
RedE Preformance Ag Products manufactured by Farmland.
Used Coulter’s would have a center that is the exact size that is needed.
I probably could get the whole thing cut with a water jet.
Just thought I’d check here to see if anyone has any available?
