The Chelsea 645XAHX-3XX or 645XAHX3XX is a 645 Series geared PTO adapter designed to solve clearance and rotation problems at the transmission PTO opening. It mounts a 6-bolt PTO to a 6-bolt transmission aperture and positions the PTO output at a 45-degree angle downward, helping eliminate interference with chassis components or nearby obstacles. The adapter uses the same input gears as the Chelsea 442 Series, which simplifies parts sourcing for shops already stocking 442 Series components.
