Description
When you’re setting up for planting season or need to replace a worn coulter on your seeder, this 18-inch smooth coulter gets your equipment back to making clean cuts through crop residue. The smooth edge slices cleanly through trash while the shallow concavity helps the blade roll through soil conditions without plugging up, so you can keep moving instead of stopping to clean out packed material.
What You’re Getting
- 18-inch diameter with 3.5mm thickness for durability without excessive weight
- Four mounting holes on a 5-inch bolt circle for secure attachment
- Shallow 1.25-inch concavity that rolls through varying soil conditions
- Smooth cutting edge that won’t grab and tear residue like notched blades can
- Quality construction from Osmundson, built to handle daily field use
Built for Real Farm Work
This coulter fits a variety of seeding and planting equipment where precise residue cutting matters. Whether you’re running a grain drill through corn stubble, no-till planting soybeans, or seeding cover crops into standing residue, the smooth edge gives you clean cuts that help maintain proper seed placement and emergence.
Made to Last
At 9-gauge thickness, this coulter strikes the right balance between cutting ability and longevity. The high-carbon steel construction holds its edge through rocky ground and abrasive soils, while the proper heat treatment ensures it won’t chip or crack when you hit something solid.
Installation Notes
This is a direct replacement for equipment using the standard 5-inch bolt circle pattern with 1/2-inch bolts. When installing, make sure your hub fits snugly in the 2-1/2 inch center hole and check that mounting bolts are properly torqued. A quick tip: if your old coulter was significantly smaller due to wear, you might need to adjust depth settings since this new blade will run deeper initially.
