This left plowshare is the ground-engaging tip of the moldboard assembly. It cuts the furrow slice and directs soil onto the moldboard for inversion. The share bolts to the frog of the plow body using the three mounting holes and the tapered screw at the point. Wear on the cutting edge increases draft force and produces an irregular furrow bottom. The manufacturer machines the share to match the frog's bolt pattern and the moldboard's leading-edge profile, so no shimming is required during installation. Torque the mounting bolts to the specification for the plow's frog.
