Description
When your disc harrow starts riding over crop residue instead of cutting through it, worn blades are usually the culprit. This 22-inch smooth disc blade from Osmundson brings your harrow back to life, slicing through stubble and residue to create the clean seedbed your crops need for strong emergence.
What You’re Getting
- 22-inch diameter with smooth edge for clean cutting and soil finishing
- Standard 2.5-inch concavity moves soil effectively without excessive mixing
- Boron steel construction with 46-52 Rockwell hardness for long-lasting cutting edges
- Single punch mounting hole fits 1-3/4 inch round axles found on many popular harrows
- 3/16-inch thickness balances durability with lighter draft loads
Built for Real Farm Work
This blade fits disc harrows using 1-3/4 inch round axles, commonly found on mid-size tillage equipment used for secondary tillage operations. Smooth blades like this one excel at creating a uniform seedbed by cutting residue and sizing clods without the aggressive action that can sometimes bring up too much moisture in wet conditions.
Made to Last
Osmundson builds these blades from boron steel that’s been heat-treated to maintain sharp cutting edges season after season. The material resists wear from abrasive soils while staying tough enough to handle rocks and root balls that would chip lesser blades.
Installation Notes
This is a direct replacement for worn blades on your harrow – no modifications needed. When replacing blades, remember to never mix worn and new ones on the same gang since the diameter difference creates uneven cutting. Check your blade spacing while you’re at it, as proper spacing ensures good trash flow and prevents plugging.
