ABSTRACT:
A hay bale ventilator in the form of an attachment for the plunger of a hay baler to progressively form a central bore or passageway through the hay bale as it is formed by the hay baler thereby reducing the tendency of hay bales to mold in the center thereof due to the moisture content of the material being baled. The hay bale ventilator is in the form of a support plate having a tapered pointed member extending therefrom with the plate being mounted on the plunger of the hay baler and the pointed member forming a hole or passageway through each segment of the hay bale as it is formed. The pointed member is of two-piece construction having a wear-resistant pointed tip removably mounted on a larger cylindrical member connected with the plate. The cylindrical member has four longitudinally extending, radially projecting ribs thereon which forms a hole through the hay bale of generally square configuration.
