Description
When your disc blades start looking more like rollers than cutting tools, it’s time for replacements that’ll actually slice through soil and residue instead of just pushing everything around. This 18-inch smooth disc blade with its 1/4-inch thickness and 1-1/8 inch square axle brings back the cutting action your harrow needs to properly work ground and prepare the perfect seedbed.
What You’re Getting
- Boron 15B26 steel construction with 46-52 Rockwell hardness that holds an edge through tough tillage but won’t shatter on field stones
- 1.63-inch standard concavity that provides good soil-throwing action for effective residue burial
- Single punch hole mounting that fits standard disc harrow gangs
- Smooth edge design that creates a clean finish and levels ground effectively
- Heavy 1/4-inch thickness for long service life in demanding field conditions
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. This blade fits disc harrows using 1-1/8 inch square axles and is perfect for primary tillage, seedbed preparation, and residue management in both conventional and no-till operations.
Made to Last
The Boron steel construction maintains the perfect hardness range – tough enough to hold an edge through acres of tillage work, but not so brittle it’ll crack when you hit that hidden rock. The 1/4-inch thickness provides the beef needed for long service life, while the quality materials resist wear and maintain cutting performance season after season.
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. Check for elongated holes from wear when installing, as loose blades wobble and wear prematurely. Track your blade wear by measuring diameter annually; most blades are shot when they’ve lost 3-4 inches.
