Ask any farmer who runs multiple crops through the same combine and you’ll hear it:
“I’m tired of swapping concaves.”
Whether it’s trying to get the settings just right for wheat after coming out of canola, or wrestling a set of cover plates to make soybeans clean up right after corn, the mid-season concave shuffle eats time, patience, and too often—profit.
If you’re still fighting with crop-specific concaves, inserts, or bolt-on band-aids, it might be time to take a serious look at Razors Edge Concaves.
Let’s face it—harvest isn’t a time for extra work. It’s a race against the weather, the calendar, and the clock. The last thing you want is to pull your concaves out of the rotor cage just because you’re switching crops. Yet with many OEM and aftermarket systems, you’re forced to swap modules, add or remove cover plates.
Razors Edge Concaves were built to eliminate that hassle.
With a patented variable bar spacing design, they’re engineered to handle corn, soybeans, wheat, canola, lentils, chickpeas, flax, barley, and more—without adjustments, cover plates, or mid-season part swaps. Tight spacing at the front delivers aggressive threshing for tough crops like wheat and barley, while the spacing progressively opens toward the back of the concave. This allows for better airflow, faster unloading, and a smoother crop flow through the rotor and onto the sieves.
You don’t need to slow down or tear your machine apart just to switch crops. Razors Edge Concaves are truly all-crop capable, straight out of the box. No cover plates. No banded modules. No crawling under the rotor to guess what’s plugged and what’s not. Just bolt them in before harvest and run clean from start to finish.
These concaves weren’t designed in a boardroom. They were built based on real-world input from farmers who were tired of stopping mid-harvest to reconfigure their machines. At Thunderstruck Ag, we’ve tested them across the toughest crop conditions—wet corn, dry lentils, green-stemmed beans, heavy canola, brittle wheat. Razors Edge holds up, performs clean, and reduces the frustration of managing different concave setups.
If you’re running a multi-crop operation and you’re tired of wasting time and yield on constant concave swaps, it’s time to upgrade. Razors Edge is a smarter, simpler, more efficient solution—and it was built for exactly the kind of farming you do.Call us at 1-855-612-7006. One set. All crops. Zero frustration.
