The Chelsea 645XDNX-3HG or 645XDNX3HG is a Power Take-Off assembly built for 6-bolt transmission openings using a 6-bolt PTO mount. Its defining design feature is a 45-degree downward angle that repositions the unit away from frame rails, crossmembers, and other underhood components that would interfere with a straight-mount PTO. The 645X series uses the same input gears as the well-established Chelsea 442 Series, which simplifies parts sourcing for shops already stocking 442 input-gear components.
