The Chelsea 645XBGX-4XX or 645XBGX4XX is a Power Take-Off assembly designed for 6-bolt PTO openings on 6-bolt transmissions. Its defining feature is a 45-degree downward offset that repositions the PTO away from chassis components, eliminating common interference problems found in tight installations. The unit shares its input gear design with the Chelsea 442 Series, giving technicians a familiar drivetrain interface. The NMFC classification (128520, Hydraulic PTOs, Pumps, Motors, etc.) confirms this as a hydraulic PTO assembly. Available from Pro Gear and Transmission.
