The Chelsea 645KJKX-3XX or 645KJKX3XX is a Geared Adapter PTO Assembly designed to mount on a 6-bolt transmission opening using a 6-bolt PTO interface. Its defining feature is a 45-degree downward angle that repositions the PTO unit to clear tight under-cab or chassis obstructions that would otherwise prevent a standard straight-mount installation. The assembly uses the same input gear set as the Chelsea 442 Series, which simplifies parts commonality for fleets already running 442 Series PTOs. Call us to confirm proper fitment for your specific transmission and chassis configuration.
