Kuchar Products: Progressive Concaves

Progressive Concaves

Kuchar All Crop Progressive Concaves have a proprietary and patented design that’s far superior to OEM concaves. Kuchar Progressive Concaves have 65 % more open area in the thresh and separation area than John Deere OEM Round Bar Concaves. 

Kuchar Progressive Concaves are slightly narrower in front and gain width toward the back,  allowing you to run a wider concave setting with more rotor speed. This results in better separation and practically eliminates rotor loss compared to OEM equipment.  

Kuchar  Progressive Concaves eliminate material build-up in the concave and improve material

flow for more capacity. You get a cleaner sample in the bin and less grain on the ground.  


Kuchar Progressive Concaves are available for Deere, Case IH, New Holland and Massey

Ferguson combines.
