This plowshare is the left-side cutting component for the front coulter assembly on a reversible plow. It mounts to the share point and leads the main body through the soil, slicing the furrow wall ahead of the moldboard. The two mounting holes align with the pre-drilled holes on the coulter frog; bolts should be torqued to the implement manufacturer’s specification on installation. A worn or chipped share edge increases draft force and produces an irregular furrow wall, which affects the following moldboard’s ability to invert the soil cleanly. This part is manufactured to the original geometry so that the cutting edge matches the angle of the frog without requiring shimming.
