Description: Mold board plows such as this cut furrows 6 to 8 inches deep and turn the soil over as shown here, thereby mixing surface vegetation into the soil. The shape of the mold boards on the same plow, shown in NAL #4791, reveal how they turn the soil over as it is towed forward through the soil. Chisel plows (NAL #4793) and rippers (NAL #4794 and #4795) may penetrate to depths as much as 18 inches. Like mold board plows, chisel plows and rippers also loosen the soil, but do not turn it over. All plows and rippers facilitate penetration of rainfall and plant growth, especially in compacted soils. These types of equipment typified those used commercially in the US in 2005.
