The Chelsea 645XITX-4HK or 645XITX4HK is a 6-bolt PTO assembly designed to mount to a 6-bolt transmission opening. Its defining design feature is a 45-degree downward offset that repositions the PTO unit away from chassis components, helping eliminate clearance and interference problems that can arise in tighter installations. The 645XITX-4HK shares its input gear set with the Chelsea 442 Series, making it a practical solution where 442 Series input gearing is already specified but additional mounting flexibility is required.
