This plastic window guard mounts over the cab window of the host tractor. It shields the glass from impact by debris, branches, or crop material during field operations. The guard is molded to match the window contour, so it does not obstruct the operator's view while providing a protective barrier. Cracking or deformation of the guard reduces its ability to absorb impact, leaving the window exposed to damage. As an original AGCO component, the guard is formed to the same curvature and mounting-hole pattern as the factory assembly, which allows direct replacement without modification.
