A couple weeks ago, I was looking for some row hippers and happened to mention it to my sister (she lives in middle of row crop farming) and a day or so later she calls me and says there is a 4 row set of industrial grade hippers at her son's place that I can have. He had bought some bearing as was going to refurbish but changed his mind. Nothing like free stuff. I only need 2 rows but the rest can be spare blades, shafts and bearings, plus the 3x3 solid steel tool bar can be useful as a drag when I cut it in half.
