Copperhead concave system designed to speed up harvest and reduce losses


Thunderstruck Ag’s Copperhead concave systems started with a look at harvest losses.

Jeremy Matuszewski of Thunderstruck Ag was at Crop Production Show at Saskatoon, Sask., to discuss the concaves, designed to fit the mainstream combine brands such as Case IH, Fendt, and John Deere.

What sets these concaves apart, says Matuszewski, are three things: adjustable cover plates, 90-degree notch cuts into the bars against the flow of grain, and the ability to measure grain loss.

The ability to get through fields faster, with fewer losses, is a large part of what attracts farmers’ attention, Matuszewski says.

“If they run pretty much any of the wire concaves or a lot of the aftermarket concaves, they can’t go faster than 2.8-2.9 miles per hour, because they’ll start putting grain out the back,” he says. “[This system] is threshing and dropping in the front 80 per cent. So I can give guys a mile per hour, and by slowing the rotor down, I can cut their fuel by 25 per cent.”
