Description
When you’re working heavy residue like corn stalks, bean stubble, or cover crops, regular disc blades just push material around instead of cutting it properly. This 28-inch notched blade from Osmundson has the Wear Tuff coating that takes blade life to the next level—the hard-faced edge stays sharp longer and cuts cleaner through the toughest conditions, meaning you can count on consistent performance season after season.
What You’re Getting
- Aggressive notched edge design that slices through tough stalks other blades just bend over
- Wear Tuff coating on the cutting edge that dramatically extends blade life in abrasive soils
- Boron 15B26 steel with 46-52 Rockwell hardness that holds an edge but won’t shatter when you hit stones
- Combo hole design fits both square and round axle systems for versatile harrow compatibility
- 5/16-inch (8mm) thickness provides the beef needed for long service life
Built for Real Farm Work
This blade fits disc harrows with 1-1/2 inch square by 1-5/8 inch round combo axles—a common configuration on many tillage tools. Whether you’re making a first pass through corn stubble or working down a field after cover crop termination, those notched edges create a scissor action that sizes residue properly instead of just moving it around.
Made to Last
The Wear Tuff coating is where this blade really shines. That hard-faced edge treatment doubles or triples blade life compared to standard blades, especially in sandy or rocky soils that wear out regular edges fast. Combined with the quality Boron steel construction, you’re looking at a blade that’ll keep working when others have given up.
Good to Know
Installation is straightforward on most disc harrows with the right axle size. When replacing blades, never mix worn and new on the same gang—the diameter difference creates uneven cutting. Store your harrow with blade edges coated in used oil to prevent rust pitting that ruins cutting ability.
