This V-belt transmits power from the drive pulley to the driven component within the chopper's drive system. It is a single-rib belt designed for the specific belt path and tensioning requirements of the host machine. A worn or stretched belt will slip under load, causing a loss of drive speed to the driven assembly and reducing chopping efficiency. The belt is manufactured to the original profile and pitch length, which ensures it seats correctly in the pulley grooves and maintains the designed tension range without requiring additional shimming or modification.
