The Chelsea 645ZAHX-3XX or 645ZAHX3XX is a geared adapter designed to mount a 6-bolt PTO to a 6-bolt transmission opening. Its 45-degree downward offset positions the PTO assembly away from chassis components, helping eliminate clearance and interference problems that a straight-mount PTO would create. The 645ZAHX-3XX shares its input gear set with the Chelsea 442 Series, which simplifies parts stocking for fleets that already run 442 Series units. Sold by Pro Gear and Transmission.
