Abstract

Apparatus is presented for slicing a large round bale into two parts prior to discharge from the baler. Slicing is accomplished by inserting a knife blade into the bale forming chamber during or subsequent to the tying-off event while the bale rotates. The knife is inserted between the belts which encircle the periphery of the baling chamber. The butt end of a more than two foot long knife blade is secured to the center of a T-shaped crossbar. One end of the crossbar is hinge mounted to the top rear midpoint of the baler. The second end of the crossbar is pivotally mounted to the piston shaft of a hydraulic cylinder. The base end of the hydraulic cylinder is pivotally mounted to the top front midpoint of the baler. In the unactivated state of the cylinder wherein the shaft is in its extended position, the top edge of the knife blade will clear the lower edge of the top front roller of the baling chamber. Activation of the cylinder to draw the shaft inward serves to rotate the sharp edge of the blade against the rotating bale. When the shaft is fully drawn into the cylinder, the tip of the blade reaches the center of the bale.
