Groundbreaking concave designs that offer an unbeatable option for farmers looking to reduce rotor loss and supercharge their harvest efficiency.

More grain for less pain! Swapping out traditional round wire combine concaves for innovative bar-and-grate style modular MAD Concaves™ results in more efficient threshing, for decreased rotor loss and less dockage. This means higher quality crops and more money in your pocket.

Quick and Easy to Change

A modular frame replaces the original concave, fits into the original concave position in the combine, and always stays in place. No need to recalibrate the concave clearance! Once the frame is installed it is never removed, and the modular concaves (15kg) are easy to insert and quick to swap out in mere minutes with two bolts per insert.

About MAD Concaves

MAD Concaves is named after brothers Murray and Dallas Skyman and business partner Alan Armstrong (MAD) who worked to design a more efficient system that would thresh wheat better and decrease loss and dockage. Since then, these specialty Concaves have been designed for various different crops to make harvest easier. In 2022, the MAD Concave business was acquired by Bushel Plus, the #1 drop pan company founded and headed up by Marcel Kringe.
