This V-belt transmits power from the engine or gearbox to the cutterbar drive on a combine harvester. It is a single-rib belt that rides in a matched pulley groove on the cutterbar drive assembly. A worn or slipping belt causes uneven cutterbar speed, leading to ragged crop cutting and increased load on the drive bearings. The belt is manufactured by Gates to match the original cross-section and length profile, ensuring proper tension and pulley engagement without requiring shimming or adapter pulleys. On installation, verify that the belt seats fully in the pulley groove and adjust the tensioner to the specified deflection.
