The Chelsea 645XESX-3XX (also referenced as 645XESX3XX) is a Power Take-Off assembly built for 6-bolt transmission openings. The unit mounts at a 45° downward angle from the transmission, a geometry designed to move the PTO away from frame rails, crossmembers, or other chassis components that would conflict with a standard straight-mount installation. Input gear compatibility matches the Chelsea 442 Series, which can simplify parts stocking on fleets already running 442 Series units. Sold by Pro Gear and Transmission.
