This chain is the drive element for the inclined conveyor on a grain harvester. It transmits torque from the lower drive sprocket to the upper drum, moving the crop mat up the feeder housing and into the threshing mechanism. A worn or stretched chain causes slip at the sprocket, leading to uneven feed rate and potential plugging of the threshing rotor. The manufacturer machines the link plates and pins to match the original sprocket tooth profile, which maintains consistent engagement and reduces wear on both the chain and the drive components. On installation, adjust the tensioner so the chain has no more than a few millimeters of slack at its midpoint.
