This plow part is the left-side moldboard share for a ZX-series reversible plow body. It is the primary soil-engaging surface on the left side of the plow, cutting and turning the furrow slice as the implement moves forward. The share mounts to the plow body frame using the provided bolt holes; the hole spacing and number of holes match the original body casting to ensure correct alignment and clamping force. A worn share will produce an irregular furrow wall and increase draft force, requiring more tractor power to maintain working depth. The manufacturer machines the share to match the original body geometry, so the cutting edge sits at the correct angle relative to the landside and the preceding share. On installation, use new hardware and tighten the bolts to the torque specification for the plow body.
