The Chelsea 645ZDAX-4DA or 645ZDAX4DA is a 645 Series Power Take-Off assembly built for a 6-bolt PTO opening on a 6-bolt transmission. Its defining design feature is a 45-degree downward angular offset that repositions the PTO unit to clear obstructions and eliminate interference issues common in tighter engine bays or chassis configurations. The input gears are interchangeable with Chelsea's 442 Series, which simplifies parts sourcing across fleets that run both series.
