This heavy implement features a curved metal blade that slices into the earth and flips the soil profile upside down. Turning the soil buries surface crop residue, weeds, and pests while bringing fresh nutrients to the surface. It leaves a deep furrow and requires significant tractor horsepower to pull through heavy ground.
