The Chelsea 645XHYX-4JB or 645XHYX4JB is a geared adapter PTO assembly designed to connect a 6-bolt PTO to a 6-bolt transmission opening. Its defining feature is a 45-degree downward angle that repositions the PTO to clear chassis components and eliminate interference common in tight installations. The unit shares the same input gears as the Chelsea 442 Series, making it a practical fit where that input gear family is already in service. Call us to confirm proper fit for your specific transmission and chassis configuration.
