The 200 Series One and Two Bottom Turning Plows improve soil before planting. The Turning Plows slice and invert the soil, sending nutrient-enriched soil to the top and burying plant residue from past crops. A Turning Plow also controls insects that live in crop debris and helps control weeds. The frames on these implements are built with heavy-duty steel and feature replaceable 14-inch plowshares and shins.
