This is a premium quality aftermarket replacement part, manufactured to meet or exceed original equipment (OE) standards for fitment and performance in agricultural environments. How do I know if it is compatible? We recommend checking your current alternator for the part number 406015A1 or 11.201.952. Note that some MTX models use an 8-groove serpentine pulley; if your tractor uses a flat multi-rib belt, please contact us at 4Drive for the Bosch-style equivalent. Can this replace a 95A version? Yes, this 120A unit serves as a high-capacity upgrade for the 95A versions, providing better charging performance for tractors equipped with extra work lights or air conditioning. Note: Professional installation is recommended. Please verify your belt profile (V-Belt vs Serpentine) before purchase. 4drive.co.uk - Quality You Can Trust.
