This armrest housing is the structural shell that supports the operator's armrest assembly inside the tractor cab. It mounts to the cab floor or console frame and provides the attachment points for the armrest pad, control switches, and any integrated joystick or display bracket. The housing positions the armrest at the correct height and angle relative to the seat, which affects operator reach to the controls. A cracked or warped housing causes the armrest to shift out of alignment, leading to operator fatigue and difficulty actuating the controls mounted on it. This component is manufactured by AGCO to match the original mounting hole pattern and internal rib geometry, so the existing armrest components transfer directly without drilling or adapters.
