Description
When your disc harrow’s blades are more like worn-down wheels than cutting tools, it’s time for replacements that’ll actually do their job. This 20-inch smooth disc blade from Osmundson brings proper cutting action back to your tillage equipment, slicing through soil and residue with the clean finish you need for good seedbed preparation.
What You’re Getting
- 20-inch diameter with smooth edge for clean cutting and soil finishing
- Boron 15B26 steel construction with 46-52 Rockwell hardness for long-lasting edge retention
- 7 gauge (4.5mm) thickness provides durability without excessive weight
- 1.88-inch concavity creates proper soil flow and mixing action
- Single punch hole design fits 1-3/4 inch round axles perfectly
Built for Real Farm Work
This blade fits medium-duty disc harrows and cultivators using 1-3/4 inch round axles. Many operators use smooth blades on rear gangs for finishing after notched blades have done the heavy cutting work up front. Whether you’re working corn ground, soybean stubble, or preparing seedbeds for small grains, this smooth blade creates the level finish you need.
Made to Last
Osmundson doesn’t mess around with blade materials – this Boron steel maintains perfect hardness to hold an edge through tough tillage without getting brittle. The 7 gauge thickness gives you the strength for years of field work while keeping weight reasonable for your harrow’s frame.
Installation Notes
Never mix worn and new blades on the same gang – the diameter difference creates uneven cutting that leaves strips in your field. Check for elongated mounting holes from wear before installing – loose blades wobble and wear out fast. Consider ordering full gang sets since shipping’s often the same cost.
