Bushel plus X9 split frame concaves

Bushel Plus has a new machinery option for farmers looking to cut down the time it takes to switch out combine concaves, and who happen to own a John Deere X9 series combine.

The Manitoba-based company recently introduced their Split-Frame MAD Concaves. The concaves are designed specifically for John Deere X9 combines, according to an early-January release from the company.

Bushel Plus says the system can significantly reduce time spent changing concaves and provide more harvesting flexibility in the process.

John Deere says it has expanded the See and Spray system’s functionality to other crops. For the 2027 model year machines, it will be compatible with wheat, barley and canola.

WHY IT MATTERS: Bushel Plus is one among several equipment manufacturers courting more efficient concave technology.

The Split-Frame MAD Concaves replace OEM versions and are designed to compliment Bushel Plus’s existing MAD concaves. They use a structural split frame that stays in place, allowing lighter inserts to be quickly removed and replaced.

“Think of it as a base frame that stays in the machine, while smaller concave inserts tailored for wheat, barley, corn, or soybeans can be swapped quickly and easily,” said Bushel Plus founder and CEO Marcel Kringe.

“Each insert fits precisely into the fixed split frame, maintaining correct spacing and alignment for optimal threshing and separation, eliminating the need for cover plates.”

The company says change time with its concaves can be as little as 15 minutes, with no need to re-level them. It also claims field trials have proven the new concaves can deliver low losses and clean grain samples in any field condition.

“Farmers can harvest faster, maintain grain quality and reduce fuel costs — improving both efficiency and profitability,” he said.

Growers can mix the Bushel Plus Split-Frame design with the other available MAD concaves, allowing for flexibility when fine tuning a combine’s performance. Placing the split frame designs in the locations most frequently changed allows for the most flexibility with the least investment, the company says.
