When your disc blades start looking more like smooth wheels than cutting tools, it’s time for replacements that’ll actually slice through crop residue instead of just pushing it around. This 20-inch notched disc blade brings back that aggressive cutting action your harrow needs, turning tough corn stalks and matted residue into properly sized pieces that’ll break down instead of hair-pinning around your planter.
What You’re Getting
- Aggressive notched edge design that creates scissor action to slice through tough stalks other blades just bend over
- Quality Boron 15B26 steel that’s hard enough at 46-52 Rockwell to hold an edge but not so brittle it shatters when hitting rocks
- 1/4-inch thickness provides the beef needed for long service life in tough tillage conditions
- 2-inch concavity creates the aggressive soil-throwing action that buries residue and levels fields
- Single punch mounting hole for secure, wobble-free attachment
Built for Real Farm Work
Your disc harrow needs to do more than just roll over crop residue – it needs to cut, size, and mix that material into the soil profile. These notched blades attack residue aggressively, with each notch creating a scissor action that slices through tough stalks other blades just bend over. Whether you’re working corn ground, breaking down cover crops, or preparing a clean seedbed, this blade handles the heavy-duty cutting that makes the difference between effective tillage and just pushing trash around.
Made to Last
Farm equipment takes a beating, and disc blades see some of the toughest conditions out there. This blade’s built from quality Boron steel that maintains the perfect balance – tough enough to handle rocks and roots without chipping, but hard enough to stay sharp through acres of cutting. No fancy coatings here, just proven steel that works season after season.
Good to Know
Notched blades excel in heavy residue but can be too aggressive in light soils or minimal trash conditions. Many operators run notched blades on front gangs for cutting, smooth on rear for finishing. When replacing blades, never mix worn and new on the same gang – the diameter difference creates uneven cutting. Check your mounting holes regularly for wear, since loose blades wobble and wear out faster.
