This V-belt transmits power from the engine pulley to the driven components in the drive system of a harvesting machine. It is a two-rib belt designed to sit in matched pulleys and maintain tension under load. A worn or slipping belt causes a loss of drive speed to the threshing or cleaning assemblies, reducing throughput. As an original-equipment manufacturer part from Gates, the belt is molded to the same cross-section and length tolerance as the original, so it seats correctly in the pulley grooves without requiring adjustment of the tensioner beyond the standard range.
