When you’re breaking new ground or working through heavy residue, you need a plow share that can handle the challenge without wearing out halfway through the season. This 18-inch left hand ribbed share gives you the extra bite and durability that tough plowing conditions demand, especially in rocky or abrasive soils where standard shares just don’t hold up.

What You’re Getting

  • Made from 1080 high carbon steel that’s heat treated and oil quenched for maximum toughness
  • Ribbed design creates turbulence in the soil for better mixing and trash flow
  • Thick construction with 3/8″ top edge and 5/8″ center front for long wear life
  • Deep suck nose design improves soil penetration and reduces draft
  • 4-hole mounting pattern for secure attachment to your moldboard

Built for Real Farm Work

This share is designed for International Harvester plows and fits a wide range of moldboard configurations. Whether you’re working corn ground in the fall, preparing seedbeds in spring, or breaking sod for new fields, the ribbed pattern helps move soil and crop residue more effectively than smooth shares.

Made to Last

The 1080 high carbon steel construction means this share will keep its edge longer and resist the kind of wear that comes from working in rocky or sandy soils. The heat treatment and oil quenching process creates a hard, durable surface that maintains its shape even under heavy use.

Good to Know

This is a direct replacement that bolts right on using your existing hardware. The ribbed pattern not only helps with soil flow but also provides more cutting surface area, which can actually reduce wear on the leading edge. Order in multiples of 6 if you’re outfitting a full plow or want to keep spares on hand for busy seasons.
