This left-side moldboard is the wear surface mounted on the furrow-wheel side of a reversible plough. It is the component that cuts and turns the soil slice as the plough moves forward. The moldboard is attached to the plough body with a single bolt; the matching right-side moldboard is a separate part number. A worn moldboard reduces furrow definition and increases draft force, requiring earlier replacement to maintain consistent ploughing depth and soil inversion. The manufacturer machines this part to the original geometry so it aligns with the plough body and shares the same bolt pattern as the original assembly. On installation, use the specified plough screw and nut, and tighten to the torque required for the plough body connection.
