The Chelsea 645GAHX-3AH or 645GAHX3AH is a geared adapter PTO assembly designed for 6-bolt PTO openings on 6-bolt transmission housings. Its built-in adapter gear repositions the PTO downward at a 45-degree angle, which helps clear frame rails, hydraulic lines, and other chassis components that would otherwise conflict with a straight-mount unit. The input gears are shared with the Chelsea 442 Series, which can simplify parts stocking for shops that already service that line. Cross-references for this part include 1450-645GAHX3AH and CHL645GAHX3AH.
