This clutch is the original component for the corn header assembly, where it transmits torque from the drive system to the gathering chains and snapping rolls. It sits between the gearbox output and the header's driven shaft, allowing the header to engage and disengage from the combine's main driveline. A slipping or failed clutch prevents the header from rotating, stopping the intake of crop material. The original manufacturer's clutch matches the factory spring rate and friction-disc material, so engagement timing and torque capacity remain consistent with the header's original design.
