MAD Concaves from Bushel Plus add efficiency to your grain harvest by minimizing crop loss. Modular inserts mount to a fixed frame so that the right concave for your crop can be installed with minimal time and effort. Put more quality grain in the hopper and less on the ground.

The Bushel Plus system provides a way to measure how much grain you are losing out of your combine. Drop the sampling tray, collect and weigh the grain, and use the phone app to calculate bushels-per-acre for most small grains.
