A hay baler or bale compressor capable of producing aerated bales of hay which can be effectively stored and shipped. Specifically, the baler includes a packer mechanism which operates to retrieve and compress individual capsules of hay and a plunger or piston that compresses the individual precompressed capsules into a large bale while simultaneously cutting and removing portions of the capsules. The plunger includes at least one tubular cutter which extends through the plunger and projects a desired distance from the face of the plunger. In operation, each time the plunger compresses the plunger load, plugs of hay are cut from capsules making up the load and passed through the tubular cutter to the throat of the baler. If a plurality of holes are formed, proper spacing of the holes allows the hay to breathe and, thus, permits shipment of large and small bales of hay without fear of premature spoiling or fire. Further, a single continuous cut hole may be formed in the resulting bale to provide aeration thereto. In addition, the tubular cutter of the present invention may be located in a position other than the baler plunger to form a continuous hole through a completed compressed bale of hay.
