Boost threshing performance and durability with this Extended Wear Large Wire Concave Set for John Deere® combines. Built for tough harvest conditions, each concave features 3/8" x 2.00" high carbon C1045 steel cross bars and heavier 5/16" side plates for unmatched structural integrity that resists warping under heavy loads. Our precision manufacturing ensures tight tolerances where the bars pass through the plates, reducing debris buildup and helping keep the concaves—and your entire threshing system—cleaner for more efficient grain separation.
This set includes three concaves and is a direct replacement for OEM Part Number BXE10391. Compatible with John Deere® combines 9660STS, 9670STS, 9760STS, 9770STS, 9860STS, 9870STS, S650, S660, S670, S670HM, S680, S680HM, S690, S690HM, S760, S770, S780, and S790.
