This wide-profile V-belt transmits power from the engine drive pulley to the combine's main drive system. It sits in the drive system, routing around multiple pulleys to drive the threshing, cleaning, and feeding assemblies. A worn or slipping belt reduces rotor speed and causes uneven crop flow, leading to plugging or incomplete separation. The belt is constructed with a wide profile to maintain contact area under load, reducing slip in dusty or high-torque conditions. On installation, ensure the belt is fully seated in each pulley groove and tensioned to the manufacturer's specification.
