The Chelsea 645XAHP-3XX or 645XAHP3XX is a 6-bolt PTO assembly designed to mount to a 6-bolt transmission opening. Its 45-degree downward offset positions the unit to help clear interference in tight drivetrain configurations where a standard straight-mount PTO would conflict with chassis or body components. The 645 Series shares its input gear design with the Chelsea 442 Series, which simplifies parts stocking for fleets already running 442-equipped vehicles.
