This V-belt transmits power from the engine to the threshing unit drive system. It is a three-rib belt that runs on pulleys within the belt drive assembly, synchronizing the rotation of the threshing drum and related components. A worn or slipping belt reduces threshing speed, leading to incomplete separation of grain from the crop. The belt is manufactured by Gates to match the original cross-section and rib profile, ensuring proper seating in the pulley grooves and correct tension retention. On installation, check pulley alignment and adjust tension to the specified deflection.
