This multi-ribbed belt drives the alternator on the host tractor. It transmits power from the engine crankshaft pulley to the alternator rotor, maintaining electrical system charge. The belt’s eight ribs engage with the matching V-grooves on the pulleys to prevent slip under load. A worn or glazed belt causes reduced alternator output, leading to battery discharge and voltage fluctuations. The belt from Contitech is manufactured to the original profile dimensions, so it seats fully in the pulley grooves without requiring tensioner adjustment beyond the standard range.
