This V-belt transmits power from the engine pulley to the header drive system on a combine harvester. It is a toothed (cogged) belt, which allows it to run on smaller-diameter pulleys and maintain grip under varying load conditions. The belt drives the rotating components of the header, including the reel and cutterbar. A worn or slipping belt causes a loss of header speed, leading to uneven crop feeding and potential plugging. As a Gates-manufactured component, it is produced to the original belt profile and tension specifications, ensuring correct engagement with the pulley grooves without requiring adjustment to the belt tensioner travel limits.
