Description

When standard disc blades just aren’t moving enough soil or burying residue like they should, it’s time to step up to deep cone blades. This 24-inch cone blade with its aggressive 4.17-inch concavity throws more dirt and creates better residue incorporation than regular blades. If you’re fighting heavy corn stalks or thick cover crop residue, those notched edges slice through what other blades just push around.

What You’re Getting

Deep cone design with 4.17-inch concavity for maximum soil throwing action and residue burial
Notched edge creates a scissor action that slices through tough stalks other blades just bend over
Quality Boron 15B26 steel at 46-52 Rockwell hardness – hard enough to hold an edge but not so brittle it shatters on rocks
Single punch mounting for quick, secure installation on 1-1/2 inch square axles
Heavy 1/4-inch thickness stands up to years of field work

Built for Tough Tillage Conditions

These cone blades excel in heavy residue situations where you need aggressive soil movement and residue incorporation. In high-residue conditions like continuous corn or after cover crops, that notched edge makes the difference between effective residue management and a plugged-up mess. The deep concave design moves more soil than standard blades, making them ideal for one-pass tillage operations where you need to size residue and prepare a good seedbed in a single trip.

Made to Last

Osmundson doesn’t mess around with blade materials – this is the same quality steel used in their standard production. The extra-deep concavity is formed without compromising the steel’s integrity, so you get the aggressive soil action without sacrificing durability. These blades hold up to the punishment of rocky ground and abrasive soils.

Installation Notes

Direct replacement for any disc harrow using 1-1/2 inch square axles with single punch mounting. When replacing blades, never mix worn and new on the same gang – the diameter difference creates uneven cutting. The deep cone design may require slight spacing adjustments compared to standard blades for optimal performance. Check your gang alignment after installation to ensure even soil engagement across the width.
