Description
If you’re running strip-till or field cultivation equipment, you know how important it is to get good seed bed preparation while managing residue properly. This wave coulter cuts through crop residue cleanly and creates the ideal soil conditions for planting, without plugging up like smooth coulters can in heavy residue conditions.
What You’re Getting
- 13 waves that slice through tough corn stalks and soybean stubble without jamming
- 20-inch diameter gives you the momentum to power through hard-packed soil
- 6 mounting holes on a 5-inch circle for secure attachment to your equipment
- 7-gauge steel construction that holds its edge season after season
- Direct replacement for Unverferth part number 93938—no modifications needed
Built for Real Farm Work
This coulter fits Unverferth strip-till machines and field cultivators, plus Rawson equipment that uses the same mounting pattern. These are the workhorses that prepare your fields in the spring and fall, whether you’re working corn ground for soybeans or getting ready for next season’s corn planting.
Made to Last
The wavy edge design isn’t just for show—those waves create a cutting action that stays sharp longer than smooth discs. The 7-gauge steel thickness gives you the durability to handle rocks, roots, and hard ground without bending or breaking when you hit something solid.
Installation Notes
This coulter bolts right on using 3/8-inch bolts through the 6 holes. The waves are about 1 inch high, so make sure you have clearance if you’re running in tight spaces. A good tip: rotate your coulters occasionally to get even wear across the entire cutting edge.
