The Chelsea 645ZJUX-3XX or 645ZJUX3XX is a geared adapter designed to reposition a PTO assembly on a 6-bolt transmission opening. Its 45-degree downward angle offset helps clear interference that a straight-mount PTO cannot avoid in tight driveline configurations. The adapter uses the same input gears as the Chelsea 442 Series, which simplifies parts stocking and allows compatibility with existing 442 Series gear sets. Bolt pattern matches both the PTO and the transmission opening with a 6-bolt interface. Call us to confirm proper fit for your application.
