If you’ve ever felt like your combine should be doing more—threshing cleaner, holding grain better, running smoother, you’re probably right. The problem may not be your combine at all; it could be you need a combine concave upgrade for higher yield
Whether you’re running OEM concaves that came standard or an aftermarket setup that hasn’t lived up to the promise, there’s a good chance your current system is holding back your harvest potential. Here’s why, and what you can do to fix it.
The Problem with Standard Concaves
OEM concaves are designed to be generalists. They’re built to perform good enough across a range of conditions, crops, and moisture levels. But “good enough” often translates into overloaded returns, cracked grain, rotor loss, and constant clogging, especially when conditions shift or when you’re harvesting multiple crops back to back.
Aftermarket options can sometimes improve on OEM, but many still force you to make compromises: swapping in cover plates, changing sections crop to crop, or settling for an aggressive design that damages grain to get it out of the rotor.
Better Design, Better Harvest
Razors Edge Concaves are built to solve those problems head-on. The difference starts with the layout. Instead of relying on wide, open bar spacing that lets grain slip through too early or skip proper threshing, the Razors Edge tightens where the crop hits hardest, up front. This design slows material down just enough to increase grain-on-grain threshing while preventing the overload you see in stock concaves.
That small change, makes a big difference. By managing the crop flow from entry to exit, Razors Edge improves separation, reduces rotor loss, and protects your grain quality.
One System, Multiple Crops—No Downtime
With the Razors Edge, you don’t need to stop and reconfigure between crops. It’s designed to handle wheat, soybeans, corn, and canola, all with the same setup. That means no swapping out sections, no adding cover plates, and no last-minute parts runs. You stay in the cab, not in the shop.
Every hour spent adjusting concaves is an hour you’re not harvesting. Razors Edge eliminates that hassle. Whether you’re switching fields or switching crops, you can keep moving. That kind of time savings doesn’t just make your day easier, it can protect your yield when weather’s closing in.
More Efficiency, Less Frustration
When your concaves are working against you, the combine has to do more to compensate. That means more fuel, more time, more wear—and more frustration. Razors Edge Concaves allow your combine to run more efficiently by improving crop flow, reducing backfeeding, and lightening the load on your rotor.
The Fix Is Simple
If you’re tired of babysitting your combine settings, chasing grain loss, or dealing with cracked kernels at the elevator, the solution is simple: you need a combine concave upgrade for higher yield. Razors Edge is designed to give you more control, more yield, and more confidence in the field.
