This concave will fit the John Deere X9. Concaves can be set up in any configuration for the same price, but our most popular set up is pictured first with the MaxThresh™ boxes in row 1 and 3, and MaxRound™ boxes in the 2nd, 4th, 5th and 6th rows. Kit includes 4 rows of MaxThresh™ boxes and 8 rows of MaxRound™ boxes unless otherwise specified. MaxThresh™ boxes available specifically for small/fine grains as well. 

The KX7 concave system centers on patented box designs, MaxThresh™ and MaxRound™. 

These boxes are designed with angled bars that meet the crop head-on, allow for customized threshing, and increase your rotary combine's capacity. The KX7 MaxThresh™ angled bars builds upon the proven benefits of a helical concave by optimizing the air flow disruption.

 The KX7 MaxRound™ brings the benefits of a helical design into the round bar category, improving threshing in corn and soybeans while also maximizing separation in small grains and cereals. 

Both MaxThresh™ and MaxRound™ are heat treated and reversible to provide increased useful life.

The KX7 concave system provides the flexibility to customize your combine's threshing chamber and maximize your productivity. The design of the MaxThresh™ and MaxRound™ boxes allows for faster threshing and maximum combine capacity. This allows you to increase your concave clearance, reducing wear on your rotor and providing more flexibility to fine tune settings.  

With the KX7 concave system, you don't have to sacrifice a clean tank or increase your losses to gain capacity. Take Control of Your Harvest!
