This V-belt transmits power from the engine or hydraulic drive to the reel assembly of a combine harvester. It sits on the pulley system that rotates the reel, which lifts and guides crop material into the header auger. A worn or slipping belt reduces reel speed, causing uneven crop feeding and increased header loss. The belt is constructed with a single rib and a standard V-profile to match the original pulley groove geometry. When replacing, ensure the belt is tensioned to specification and that the pulleys are aligned to prevent premature edge wear.
