I know years ago bmb in holton ks built blades, rotary mowers, plows, etc. They sold out to Alamo group and moved the plant to Illinois. That is one place to check. Also king cutter in Alabama makes rotary mowers, tillers, little 3 pt disks, blades, etc. That maybe another place to check. If you have a tractor supply or an orschelns, you migut check with them and see if they have an outlet and can order you one. Other options it take out a wanted to buy ad in your newspaper or watch for one at an auction. You will definitely want to stay with a one bottom plow. Hope this helps.
