The Thrash Master Concave System increases the thrashing surface area which gives your machine the ability to thrash better and more aggressively.

Swapping out traditional round wire combine concaves for these innovative bar-and-grate style modular MAD Concaves™ results in more efficient threshing, getting your grain out of the head and into the hopper quicker for decreased rotor loss and less dockage.
