This V-belt transmits drive from the engine to the chaff distributor on the parent combine. It sits in the drive system, routing power to the rotating distributor that spreads chaff behind the machine. A worn or slipping belt reduces distributor speed, leading to uneven chaff distribution and potential blockages in the discharge path. The belt is manufactured by Gates to match the original cross-section and length, ensuring correct tension and pulley engagement without requiring adjustment of the idler beyond the standard range.
