Description
When your disc harrow starts skating over crop residue instead of cutting through it, you know it’s time for new blades. This 18-inch notched disc blade brings back the aggressive cutting action your harrow needs to slice through tough stalks and incorporate residue properly, instead of just pushing it around to clog up your planter next spring.
What You’re Getting
- Aggressive notched edge design that creates a scissor action to slice through tough stalks and matted residue
- Premium Boron 15B26 steel construction with 46-52 Rockwell hardness for durability
- 9-gauge thickness (3.5mm) provides the right balance of strength and cutting performance
- Standard 1.63-inch concavity creates proper soil throw and residue mixing
- Combo hole design fits 1-1/8 square to 1-1/4 square axles without adapters
Built for Real Farm Work
This blade handles the tough conditions you face during spring tillage and fall residue management. Whether you’re working through corn stalks, incorporating cover crops, or preparing seedbeds, the notched edge cuts aggressively while the proper concavity ensures good soil mixing and leveling. The combo axle hole means it’ll fit a wide range of disc harrow makes and models.
Made to Last
This Boron 15B26 steel maintains the perfect hardness range – hard enough at 46-52 Rockwell to hold an edge through acres of tough tillage, but not so brittle it shatters when you clip that hidden field stone. The 9-gauge thickness gives you the durability to handle rocks and roots without being so thick it won’t cut properly.
Good to Know
This is a direct replacement that bolts right on – no modifications needed. When replacing blades, swap out the whole gang at once to maintain consistent cutting diameter. The notched edge is more aggressive than smooth blades, making it perfect for heavy residue conditions but maybe too much for light tillage work in clean fields.
