The Chelsea 645XITX-4HB or 645XITX4HB is a geared adapter PTO assembly designed to mount a 6-bolt PTO to a 6-bolt transmission opening. Its defining feature is a 45-degree downward angular offset that repositions the PTO output away from common interference points on the chassis or body, making it a practical solution on tight installations. The unit uses the same input gears as the Chelsea 442 Series, so shops familiar with that platform will recognize the gear set. The part is also referenced as SP645XITX-4HB.
