This V-belt transmits power from the engine to the driven components within the forage harvester's drive system. It connects the drive pulley to the input shaft of the main gearbox, enabling the chopping and conveying mechanisms to operate. A worn or stretched belt slips under load, causing a loss of cutting speed and inconsistent material flow. As an original component from the equipment manufacturer, the belt is molded to the same profile and pitch length as the original assembly, so it seats correctly in the pulley grooves without requiring tensioner adjustment beyond the standard range. On installation, verify the belt is not twisted and tension it to the manufacturer's specification.
