This is our smooth-edge blade — no flutes at all, which puts it in a different category from every other blade in our lineup. Without flutes there’s no edge to grind down over time, so it holds up more like a disc blade and lasts longer than a fluted blade running the same ground.
The full concavity — a deeper cup than a flat blade — gives it more tension strength, which matters on machines running a heavier gang angle. It’s an Ingersoll design decision, not something we changed: a stronger cup shape holds up better under that added load.
Where this blade earns its place is harder, drier soil, where you don’t need a flute to fracture the ground and durability matters more than penetration. It’s not the right pick everywhere, though — if you’re in sand or heavy clay with a lot of residue, a fluted blade like our Soil Razor line will penetrate and handle residue better than a smooth edge can.
Field Notes
On a 22″ blade, start measuring once it’s been in the ground a season. Replace once it wears down to about 20 1/2″ — you’re losing tension strength along with diameter as the concavity wears.

Frequently Asked Questions
What’s the advantage of a smooth blade over a fluted one?
No flutes means no edge to grind down, so it holds up more like a disc blade and lasts longer than a fluted blade running the same ground. The tradeoff is penetration — a fluted blade fractures soil a fluted-edge blade can’t match.
Is this blade right for sandy or residue-heavy fields?
Probably not this one. It’s built for harder, drier soil. In sand or heavy clay with a lot of residue, a fluted blade like our Soil Razor line will penetrate and handle residue better.
Why does this blade have a deeper concavity than your other blades?
The full concavity gives it more tension strength, which matters on machines running a heavier gang angle — it’s an Ingersoll design choice built for that added load, not something we changed.
Does this blade fit both Great Plains and Landoll machines?
Yes — it cross-references to Landoll Part #155617 across several 7000-series VT models and Great Plains #82-445C across several DH-series models. Full model lists are in the spec block above.
