This variator belt transmits power between the engine pulley and the driven pulley in the variable-speed drive system of the host tractor. It sits in the engine compartment and adjusts the drive ratio to match the operating speed of the implement or ground drive. The belt is an original AGCO component, manufactured to the same cross-section and length tolerances as the original assembly, which ensures proper tension and alignment without requiring shimming or additional adjustment. A worn or glazed belt slips under load, causing inconsistent speed control and reduced power transfer to the driven equipment. On installation, verify the belt tracks correctly in the pulley grooves and adjust tension to the specified deflection.
