Years ago, most farmers in some areas of the midwest used one-ways (similar to a moldboard plow, except replace these plows with a 6' to 12' section of 16" to 24" ciameter discs, approx 8" apart, and all on the same 1" to 2" shaft). OR, like a disc plow, except built for going only 2" to 5" deep. Are one-ways in use today, or are they all setting in fencerows? Herb
