Model John Deere S/STS Series Combines -Mad Concaves

Swapping out traditional round wire combine concaves for our 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. This means higher quality crops and more money in your pocket. Our fast and easy-to-change modular designs allow you to quickly swap out inserts in minutes, making it way easier to customize your concaves to your crop for the best results possible. Plus, you’ll save valuable time, which is critical in a busy harvest season.
