Large-scale farmers might grow oats, barley, canola, sunflowers, soybeans, and corn. Accommodating this variability can mean expensive delays from changing concaves, the part on a combine that separates grain from chaff.
Thunderstruck’s founder Jeremy Matuszewski debuted the Razors Edge Concaves last November to save that time. “The [concaves’] bar spacing…is variable based on crop flow, which balances the combine,” meaning farmers don’t have to change concaves between crops, Matuszewski says. Per field tests, the Razors Edge Concaves increased harvesting speed by 25%, reduced grain loss, and decreased fuel consumption by 40%.
