Dearborn (vintage-antique) two-way plow. For 3-point tractor like 9N, 8N, etc. I ran it on my 9N. Ingenious design where plow moldboards switch direction upon raise and lower on 3-point tractor. Allows throwing dirt left on first pass, then reverse direction which lowers the other moldboard while raising the first, then second moldboard throws dirt left again on reverse pass. No looping in your field. One of the moldboards is broken but I have the broken piece. Just needs to be welded back in place. Located in Bountiful. $100.00 OBO and I'll set it in your truck bed.
