This left plowshare is the ground-engaging component that cuts the furrow wall on the left side of the plow body. It mounts to the frog or shin of the plow bottom and leads the share point into the soil, initiating the slice that the moldboard then inverts. The three mounting holes align with the plow body's bolt pattern; the bolt holes are spaced to match the standard geometry of the host plow bottom. A worn share increases draft force and produces an irregular furrow wall, reducing residue incorporation and seedbed uniformity. This original-manufacturer share is formed to the same profile and thickness as the assembly it replaces, so the cutting edge maintains the correct landside clearance and does not require re-shimming on installation. When replacing, use new plow bolts torqued to the manufacturer's specification and check the fit against the shin and landslide.
