This V-belt transmits power from the engine crankshaft to the driven components in the drive system of a self-propelled forage harvester. It sits in a single-groove pulley arrangement and transfers torque to the input shaft of the implement or auxiliary drive. A worn or stretched belt slips under load, causing a loss of drive speed to the chopping or feed mechanism. The manufacturer matches the original belt’s cross-section and length to maintain proper tension and pulley wrap. On installation, verify the belt seats fully in the pulley groove and adjust the tensioner to the specified deflection.
