The inventor behind TIME Best Invention Razors Edge Concaves launches his second combine upgrade to help farmers keep more of their harvest

Thunderstruck Ag, a global provider of farmer-driven equipment solutions, today announced the launch of the TNT Separating System, a patent-pending combine upgrade designed to help farmers keep more of the grain they harvest. It is built to recover grain that would otherwise be thrown out with the stalks and leaves, and to keep more of that debris out of the harvested grain. The TNT Separating System debuts this week at the Agri-Trade Equipment Expo, with orders now being accepted for the 2027 harvest.

The system was co-invented by Thunderstruck Ag founder and CEO Jeremy Matuszewski, whose Razors Edge Concaves were named to TIME’s Best Inventions of 2025, and Vincent Pawluski, an Alberta farmer and inventor of the RC Farm Arm. Razors Edge improves how grain is knocked loose at the front of the combine. TNT targets the back of the machine, where the last of the grain is separated before the leftover stalks and leaves are thrown out.

For farmers, every bushel lost during harvest is money left in the field, and with margins as tight as they are, farmers can’t afford to leave grain behind. Recovering more of the grain they have already grown is one of the most direct ways to protect their bottom line.

“TNT came out of conversations with farmers about how difficult it is to avoid losing grain at the back of the combine, especially in extreme wet or dry conditions,” said Matuszewski. “We developed a solution and tested it on farms this past harvest. Farmers can’t afford to lose grain they’ve already paid to grow, and recovering more of it goes straight to the profitability of their operations.”

TNT is the first system designed to work across the entire back of the combine, both holding back excess debris and breaking it up to free trapped grain. Openings that narrow from front to back let grain fall through early, while raised bars loosen the plant material, so grain still caught in it isn’t thrown out with the stalks and leaves. TNT replaces the existing grates and works with any brand of concave.

Thunderstruck Ag is offering 150 systems for the 2027 harvest. TNT is available for John Deere STS/S-Series and X9, Case IH Flagship and AF11, New Holland CR11, and Fendt IDEAL combines. Farmers can order at Agri-Trade Booth #558 or at www.thunderstruckag.com.
