The Real Cost of Grain Loss: Why Upgrading Your Concaves Pays Off

There’s a lot going on in the cab at harvest—monitoring yield, watching your ground speed, trying to beat the forecast. So when it comes to grain loss, it’s easy to rely on what the monitor says or assume what’s coming out the back is “normal.”

But here’s the thing: even a small amount of loss at the rotor or sieves adds up fast. And unless you’ve checked it with a pan, you might be leaving real money in the field without realizing it.

What Does Grain Loss Actually Cost?

Let’s say you’re losing just 2 bushels per acre. That might not seem like much when you’re watching grain fly out the back in the field—but across 2,000 acres at $10/bushel, that’s $40,000 gone.

And that’s a conservative number. We’ve seen loss from poorly adjusted rotors or overloaded sieves hit 4, 5, even 6 bushels an acre—especially in tough threshing conditions like green stems, lodged cereals, or high-yield canola.

It’s not just money lost. It’s time, seed, fertilizer, fuel, and labor—wasted.

Where It Happens: Rotor and Sieve Loss

Most of the grain gets tossed out the back during separation and cleaning. If your concaves aren’t threshing efficiently, or if they’re not matched to your crop conditions, you end up with grain still in the heads at the rotor—or too much material piling onto the sieves.

Once the separator’s overloaded, it’s game over. Grain rides out with the chaff, and the combine can’t keep up.

How Razors Edge Concaves Help

Razors Edge Concaves are built to improve threshing performance where it matters most. By aggressively and evenly threshing grain right up front, they reduce the load on your separator and cleaning system. That means:

  • More grain gets separated at the rotor, not carried out the back.
  • Lower rotor speeds can be run without sacrificing throughput.
  • Sieve load is reduced, so less grain gets blown out with the chaff.
  • Cleaner samples in the tank, and less re-threshing.

All that leads to a measurable drop in grain loss—and more bushels in the tank.

The ROI Is in the Results

If upgrading your concaves cuts just 1 bushel of loss per acre, you could pay off your investment in one season. But in many cases, the savings are even higher.

Farmers who switch to Razors Edge aren’t doing it for bells and whistles—they’re doing it because they want to keep more of what they grow. The dollars add up fast when you’re putting more grain in the hopper instead of watching it disappear out the back.

Bottom line: You’ve done the hard part—growing the crop. Don’t let outdated concaves or inefficient threshing take away from your bottom line. Razors Edge isn’t just about performance—it’s about profit per acre.
