Description

When you need precise soil finishing without the aggressive cutting of notched blades, this 22-inch smooth disc blade delivers the controlled tillage action that creates ideal seedbed conditions. Many operators run notched blades on front gangs for cutting, smooth on rear for finishing, and this blade excels at that finishing work. The smooth edge cuts cleanly through light to moderate residue while creating the fine, level surface that planters and drills perform best on.

What You’re Getting

22-inch diameter with smooth edge for precise finishing work
Hard enough at 46-52 Rockwell to hold an edge through acres of tough tillage, but not so brittle it shatters when you clip that hidden field stone
Quarter-inch thickness provides durability for long service life
2.50-inch concavity creates proper soil flow and mixing action
Single punch mounting for straightforward installation

Where This Part Shines

This blade fits disc harrows and tillage implements using 1-3/4 inch round axles. It’s perfect for secondary tillage work where you need to smooth out the rough work done by primary tillage tools. Whether you’re prepping ground after disking or cultivating between crop rows, this smooth blade gives you the control to create the exact seedbed conditions your crops need without over-working the soil.

Built to Handle Real Farm Conditions

Osmundson doesn’t mess around with blade materials. No fancy coatings here – just quality steel that works. The Boron 15B26 steel construction maintains its edge through season after season of demanding fieldwork, while the robust quarter-inch thickness stands up to rocks, roots, and everything else hiding in your fields.

Installation Notes

This is a direct replacement blade that mounts with the single punch hole design. Never mix worn and new on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips. Check for elongated holes from wear – loose blades wobble and wear prematurely. A quick tip: coat blade edges with used oil to prevent rust pitting that ruins cutting ability when storing your equipment.
