The Chelsea 645XJAX-4XX or 645XJAX4XX is a power take-off assembly built for 6-bolt transmission openings. Its defining feature is a 45° downward angular offset that moves the PTO away from chassis obstructions, making it a practical choice when a straight-mount unit creates interference with frame rails, hydraulic lines, or other underhood components. The unit uses the same input gear set as the Chelsea 442 Series, which can simplify parts stocking for fleets already running that platform.
