Description
When you need clean, level fields without the aggressive cutting action of notched blades, this smooth disc blade delivers the finishing touch your soil demands. Many operators run notched blades on front gangs for cutting, smooth on rear for finishing, and this 18-inch smooth blade fills that finishing role perfectly. It’s the blade that creates that final, even seedbed you’re after.
What You’re Getting
- 18-inch diameter with smooth edge for gentle soil finishing and leveling
- 3/16-inch thickness provides durability without excess weight
- Boron 15B26 steel maintains the perfect hardness range – hard enough at 46-52 Rockwell to hold an edge through acres of tough tillage
- Single punch mounting with 1-1/2 inch square axle hole for direct replacement
- Standard 1.63-inch concavity moves soil effectively without being too aggressive
Built for Real Farm Work
This blade fits disc harrows using 1-1/2 inch square axles and excels where you need soil mixing and leveling without heavy residue cutting. It’s perfect for secondary tillage operations, seedbed preparation, and working fields with lighter residue loads. Notched blades excel in heavy residue but can be too aggressive in light soils or minimal trash conditions – that’s exactly where smooth blades like this one shine.
Made to Last
Farm conditions don’t take prisoners, and this blade is built to handle whatever you throw at it. The Boron steel isn’t so brittle it shatters when you clip that hidden field stone, while the 3/16-inch thickness provides the right balance of strength and performance for years of reliable service.
Good to Know
When replacing blades, never mix worn and new on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips. The single punch mounting means checking 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 during storage.
