The Chelsea 645XHYX-4XX or 645XHYX4XX is a geared adapter designed to mount a 6-bolt PTO to a 6-bolt transmission opening. Its 45-degree downward offset repositions the PTO to clear interference points that a straight-mount unit cannot avoid, making it useful on applications where underhood or underbody clearance is tight. The adapter uses the same input gears as the Chelsea 442 Series, so it integrates with that proven gear train without requiring a different PTO unit. Call us to confirm proper fit for your transmission and application before ordering.
