Description
When your vertical till isn’t slicing through residue like it should, worn turbo blades are usually the culprit. Your disc harrow needs to do more than just roll over crop residue – it needs to cut, size, and mix that material into the soil profile. These notched blades from Osmundson attack residue aggressively, with each notch creating a scissor action that slices through tough stalks other blades just bend over. This 18-inch turbo blade brings back the aggressive cutting action that makes vertical tillage work.
What You’re Getting
- Boron 15B26 steel maintains the perfect hardness range – 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
- Shallow concavity design that cuts precisely without over-mixing the soil profile
- Single punch mounting hole for secure, wobble-free attachment
- 1/4-inch thickness provides durability for extended field life
Built for Real Farm Work
This turbo blade is designed for vertical tillage implements working in high-residue conditions. Whether you’re sizing corn stalks after harvest, preparing a clean seedbed, or managing cover crop residue, the turbo design cuts aggressively while maintaining soil structure that traditional discs can destroy.
Made to Last
This Boron 15B26 steel maintains the perfect hardness range – 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. The shallow concavity and smooth edge work together to slice cleanly without the soil disturbance that deeper blades create.
Installation Notes
The single punch mounting means checking for elongated holes from wear – loose blades wobble and wear prematurely. When replacing, inspect the mounting hardware and consider replacing the entire gang if wear is uneven. When storing disc harrows, coat blade edges with used oil to prevent rust pitting that ruins cutting ability.
