Description
When your disc blades start looking more like smooth wheels than cutting tools, it’s time for replacements that’ll actually slice through residue instead of just pushing it around. This 22-inch notched disc blade with 3/16-inch thickness brings aggressive cutting action back to your harrow, turning tough corn stalks and matted crop residue into properly sized pieces that’ll break down instead of hair-pinning around your planter come spring.
What You’re Getting
- Combo hole mounting for versatile axle compatibility with 1-1/8 square by 1-1/4 square configuration
- Boron 15B26 steel construction with 46-52 Rockwell hardness for durability – hard enough to hold an edge through acres of tough work, but won’t shatter when you clip that hidden field stone
- Notched edge design creates a scissor action that slices through tough stalks other blades just bend over
- Standard 2.50-inch concavity provides proper soil penetration and mixing action
- 3/16-inch thickness (5.0mm) offers the right balance of weight and strength for medium-duty tillage work
Built for Real Farm Work
In high-residue conditions like continuous corn or after cover crops, that notched edge makes the difference between effective residue management and a plugged-up mess that forces you to make extra passes. This blade fits disc harrows that use the combo hole pattern, making it a direct replacement for worn blades on many popular harrow brands. Whether you’re working corn ground, bean stubble, or preparing seedbeds, this blade handles the job.
Made to Last
The 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. No fancy coatings here – just quality steel that works. You’ll get reliable performance season after season without worrying about premature wear or breakage.
Good to Know
When replacing blades, never mix worn and new on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips. When storing your harrow, coat blade edges with used oil to prevent rust pitting that ruins cutting ability, and track your blade wear by measuring diameter annually. Most blades are ready for replacement when they’ve lost 3-4 inches from their original diameter.
