The Chelsea 645XAWX-3XX or 645XAWX3XX is a power takeoff assembly designed to mount on a 6-bolt transmission opening with a 6-bolt PTO face. Its defining feature is a 45-degree downward angular offset, which repositions the PTO output to help clear chassis components and eliminate interference issues common in tighter engine compartments or frame-rail layouts. The unit shares its input gear set with the Chelsea 442 Series, which simplifies parts sourcing for fleets already running 442 Series PTOs.
