This multi-ribbed belt transmits power from the engine crankshaft to the accessory drives and the cooling fan. It is a four-rib component designed to maintain tension across the pulleys in the drive system of the host tractor. A worn or glazed belt slips under load, causing reduced alternator output and elevated coolant temperature. The manufacturer produces this belt to match the original pulley profile and rib spacing, ensuring the belt seats fully in each groove without edge wear. On installation, verify the belt tensioner is within its travel range and that the belt does not contact any stationary surfaces.
