This multi-ribbed belt drives the alternator from the engine crankshaft. It sits in the front drive system of the host tractor, transmitting rotation to maintain battery charging and electrical system voltage. The belt has four ribs along its length, which engage with matching pulleys on the crankshaft and alternator. A worn belt slips under load, causing the charge warning light to illuminate and battery voltage to drop. Gates manufactures this belt to match the original rib profile and length, so it seats fully in the pulley grooves without requiring tensioner adjustment beyond the standard range.
