This V-belt transmits power from the engine pulley to the driven components in the drive system of a harvesting machine. It is a three-rib belt that sits in the pulley grooves and transfers torque to the auxiliary drives, such as the cleaning fan or the header drive. A worn or slipping belt causes reduced rotational speed at the driven end, leading to lower throughput or uneven crop flow. The belt is manufactured by Gates to match the original cross-section and length, so it seats correctly in the pulley grooves without requiring tensioner adjustment beyond the standard range.
