Tractor grille and grille guard hood

In a tractor having a frame, a grille has a hollow frame fastened to a front portion of the frame of the tractor, so as to protect a radiator of the tractor. Two brackets are provided, each of which is mounted to the front portion of the frame of the tractor and each of which projects frontwardly from the frame of the tractor, through an aperture in a lower portion of the frame of the grille. A guard is provided, which is fastened to the brackets, in front of the grille, so as to protect the grille. The hollow frame of the grille is fastened to the front portion of the frame of the tractor only at the lower portion of the frame of the grille. The hollow frame of the grille is molded, as by rotational molding, from a polymeric material, for which cross-linked polyethylene is preferred. The brackets and the guard are made of steel.
