The Chelsea 645ZITX-3XX or 645ZITX3XX is a geared PTO adapter assembly designed for 6-bolt transmission openings. Its defining feature is a 45-degree downward angular offset that repositions the PTO to clear frame rails, crossmembers, or other chassis components that would interfere with a standard straight-mount unit. The assembly uses the same input gears as the Chelsea 442 Series, which simplifies parts commonality for shops already running that platform. Cross-references for this unit include 1450-645ZITX3XX, 1450645ZITX3XX, and CHL645ZITX3XX. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your specific transmission and chassis.
