KX7 Concave set for John Deere combines for Tough-Thresh conditions, used for Corn and Soybeans.At half the width of most traditional concaves, KX7 concaves allow for greater customization of threshing configurations to specific field and crop conditions. The smaller design also allows for easier installation. KX7 concaves have been proven effective in various crops and conditions around the world.Replaceable boxes in each assembly include unique angled bars that meet the crop head-on. This design not only results in a better thresh, but allows for increased air flow disruption that results in greater capacity for improved combine productivity.Fits John Deere combines 9650STS, 9660STS, 9670STS, 9750STS, 9760STS, 9770STS, 9860STS, 9870STS, S650, S660, S670, S680, S690, S760, S770, S780.Set includes front lip, 1 Tough-thresh concave (BA2-X04), and 5 standard thresh concaves (BA2-R02).
