Notched Disc Blade for Disc Harrows with 1 Inch Square Axle

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 brings aggressive cutting action back to your harrow, turning tough corn stalks and matted residue into properly sized pieces that’ll break down instead of hair-pinning around your planter next spring.

What You’re Getting

• Each notch creates a scissor action that slices through tough stalks other blades just bend over
• Boron 15B26 steel maintains perfect hardness at 46-52 Rockwell Scale for long-lasting cutting edge
• 3/16-inch thickness provides durability without excess weight on your harrow gangs
• 2.50-inch concavity creates proper soil-throwing action for effective residue burial
• Single punch mounting hole ensures secure, proper blade spacing on your axle

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. 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 with 1-inch square axles, commonly found on mid-size tillage equipment perfect for row-crop farming operations.

Made to Last

The Boron steel is hard enough 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. The heat-treated construction stands up to the constant impact and abrasion of cutting through everything from corn stalks to compacted soil.

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. The single punch mounting means checking for elongated holes from wear – loose blades wobble and wear prematurely. When replacing, never mix worn and new blades on the same gang as the diameter difference creates uneven cutting.
