Description
When you’re trying to get a clean finish on your seedbed prep or need smooth soil mixing without the aggressive cutting action, this 26-inch smooth disc blade delivers the controlled tillage you’re looking for. Unlike notched blades that attack everything in sight, smooth blades like this one give you that even, consistent cultivation that leaves your field ready for planting.
What You’re Getting
- 26-inch diameter provides good soil penetration and mixing action for mid-sized disc harrows
- Smooth edge design gives you clean, even cultivation without the aggressive cutting of notched blades
- Combo hole pattern with 1-1/4 inch square x 1-1/2 inch round axle fits a wide range of disc harrows
- Boron 15B26 steel construction with 46-52 Rockwell hardness that holds an edge but won’t shatter on rocks
- 5/16-inch (8mm) thickness provides durability for seasonal use without being overly heavy
Built for Real Farm Work
This blade fits disc harrows using the combo axle setup – those machines where you’ve got both square and round axle sections. Whether you’re working corn ground in the fall, prepping soybean stubble, or doing light tillage on summer fallow, smooth blades give you that consistent finish without tearing up crop residue into tiny pieces that blow around.
Made to Last
The Boron steel construction maintains the perfect hardness range – hard enough to hold an edge through acres of tough tillage, but not so brittle it shatters when you hit that hidden field stone. The 4-inch concavity gives you good soil-throwing action while the smooth edge design reduces wear compared to notched blades in lighter tillage conditions.
Installation Notes
This is a direct replacement that fits right onto your existing axle. Never mix worn and new blades on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips in your field. While you’ve got the gangs apart, it’s a good time to check bearing condition and make sure your spool spacing is still correct for even blade wear.
