Description
When your disc blades start looking more like dull coins than cutting tools, you need replacements that’ll actually bite into the soil instead of just riding over the surface. This 24-inch smooth blade brings back that clean cutting action your harrow needs to properly break up ground and leave a seedbed ready for planting. At 6.5mm thick with that smooth edge, it’s built for finishing work and maintaining an even depth across your field.
What You’re Getting
- Boron 15B26 steel construction with 46-52 Rockwell hardness that holds an edge through acres of tough tillage but won’t shatter when you hit that hidden rock
- 1-3/4 inch round axle mounting for secure fit without wobbling or premature wear
- Rollable steel construction makes sharpening easier when the time comes
- 3-inch standard concavity provides the right soil-throwing action for effective cultivation
- Single punch hole design reduces stress points that can cause cracking
Built for Real Farm Work
This blade fits Landoll 6000 and 7000 Series disc harrows along with Sunflower 1200, 1400, 1500, and 6631 Series units. These are the workhorses you see breaking up corn ground in the fall and prepping bean stubble for next year’s crop. Whether you’re working heavy clay or sandy loam, smooth blades like this one give you that consistent finish without the aggressive cutting action of notched blades.
Made to Last
Osmundson doesn’t mess around with blade materials – this Boron steel maintains the perfect hardness range for long service life without fancy coatings, just quality steel that works. The rollable design means when these do eventually dull, you can actually sharpen them instead of just throwing them away.
Installation Notes
This is a direct replacement that threads right onto your existing axle. Never mix worn and new blades on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips in your field. While you’ve got the gangs apart, check your bearing condition and spool spacing to make sure everything’s running true.
