The Chelsea 645XDAX-3XX or 645XDAX3XX is a geared adapter Power Take-Off (PTO) designed to mount to a 6-bolt transmission opening using a 6-bolt PTO interface. Its defining feature is a 45-degree downward angular offset, which repositions the PTO assembly to clear chassis obstructions and eliminate interference problems that a straight-mount unit cannot avoid. The adapter uses the same input gears as the Chelsea 442 Series, making it a practical solution when a standard 442 Series PTO fits the transmission but the mounting angle creates a clearance conflict. Call us to confirm proper fit for your specific transmission and chassis configuration.
