This V-belt transmits power from the engine drive pulley to the driven components in the combine’s drive system. It is a single-rib belt designed for the primary power loop, where it maintains tension to prevent slip under variable load during harvesting. A worn or stretched belt causes speed loss at the driven shaft, leading to reduced throughput or component stalling. As a Gates-manufactured belt, it is constructed to match the original cross-section and length specifications, ensuring correct tension and pulley engagement without requiring shimming or adapter pulleys.
