They are out there. Search Facebook marketplace and Craigslist. I have one in NE Connecticut that I am going to be selling once the snow flies. I have found in the past that once there is snow on the ground, plows become a lot more valuable. I kept it when I sold my tractor since I thought that I might be able to adapt it to my new BX23s, but last spring I found a very lightly used one for the new tractor.
I have been looking for the plow that goes on the loader are quick attach, and that one is next to impossible to find.
