This toothed V-belt transmits power from the engine pulley to the driven components in the drive system of a self-propelled forage harvester. The teeth on the inner face allow it to engage with smaller-diameter pulleys without slipping, which is necessary for maintaining consistent drive speed to the chopping and conveying assemblies. A worn or glazed belt will cause speed loss under load, leading to reduced throughput and potential plugging of the feed rolls. This belt is manufactured to the original profile dimensions 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 that the tensioner arm moves freely before applying the specified preload.
