The Chelsea 645ZAHX-4XX or 645ZAHX4XX is a 645 Series power take-off assembly designed with a 6-bolt PTO-to-6-bolt transmission opening. A 45-degree downward angle positions the unit lower on the transmission, reducing clearance conflicts that commonly occur with standard straight-mount PTOs. The 645 Series shares its input gear set with Chelsea's 442 Series, which can simplify parts stocking for shops already running 442 Series units. Call us to confirm proper fitment for your specific transmission and application before ordering.
