Description
When you need clean, consistent cutting action without the aggressive bite of notched blades, this smooth disc blade delivers the finishing touch your fields deserve. Smooth blades give you that consistent finish without the aggressive cutting action of notched blades, making them perfect for secondary tillage and seedbed prep where you want to level and smooth rather than tear apart crop residue.
What You’re Getting
- Smooth edge design for even cutting and soil finishing that won’t over-till delicate soils
- Premium Boron 15B26 steel with 46-52 Rockwell hardness for long-lasting edge retention through acres of tough work
- Wear Tuff coating adds extra durability and extends blade life in abrasive conditions
- Single punch mounting design fits standard 1-1/8 inch square axle harrows securely
- Quarter-inch thickness provides the durability needed for demanding farm operations
Built for Real Farm Work
This blade fits disc harrows with 1-1/8 inch square axles and standard gang spacing. Whether you’re working corn stubble in the fall, preparing bean ground for planting, or doing secondary tillage on wheat stubble, smooth blades excel where you need consistent soil movement without the residue-chopping aggressiveness of notched blades. Many operators run notched blades on front gangs for cutting, smooth on rear for finishing.
Made to Last
Ingersoll builds these blades from heat-treated Boron steel that’s specifically formulated for disc blade applications. The Wear Tuff coating provides additional protection against wear from sand, rocks, and abrasive soils that would normally eat up standard blades faster. At 24 inches diameter and quarter-inch thick, this blade is built to handle real farm conditions season after season.
Good to Know
This is a direct replacement that mounts with a single punch hole on standard square axles. When replacing blades, never mix worn and new on the same gang – the diameter difference creates uneven cutting. Check your gang spacing when switching between smooth and notched blades, as they sometimes require slightly different spacing for optimal performance.
