This window hinge is the original AGCO component for the cab door or window of the host tractor. It provides the pivot point for the glass or panel, allowing it to swing open and remain aligned with the cab frame. A worn or corroded hinge causes the window to sag, leading to misalignment and difficulty latching the door closed. The original part matches the factory-specified pivot geometry and mounting-hole pattern, so the window panel sits flush and seals properly against the cab weatherstrip without requiring shimming or adjustment.
