This chain transfers crop material from the feeder house into the threshing mechanism. It is the primary conveying element in the material feeding assembly, moving the crop mat from the feed drum to the threshing cylinder. The paddles attached to the chain carry the material across the width of the feeder housing. A worn or stretched chain causes uneven feeding, which can lead to slug loading and threshing losses. This component is manufactured to the original pitch and roller geometry, so it engages the sprockets without backlash. On installation, verify the chain tension is within the specified range and that all paddles are oriented in the forward direction of travel.
