Abstract: An attachment for a combine and more specifically to a shredder attachment for a combine corn head to shred or chop corn stalks as they pass downwardly through the feed rolls on a combine corn head with the shredded materials being discharged onto the ground surface. The shredder attachment includes a plurality of cutter assemblies each including a pair of rotary cutter bars each in the form of a circular disk or plate having flat cutter blades attached thereto at the periphery with the rotary cutter plates in each cutter assembly being driven in opposite directions with the cutter bar blades overlapping the row of stalks by several inches to assure complete shredding action. The cutter assemblies are each driven by a hydraulic motor and a spur gear drive train oriented in a gear box with the spur gears running in oil. Hydraulic pressure is provided to the hydraulic motor from a pump assembly that is belt driven from a cross shaft on the combine head.

Abstract: A shredder attachment for a round bale hay baler which will effectively shred corn stalks or stubble, milo stubble and the like and discharge the shredded stubble into a round bale hay baler which will form a bale of stubble which has been shredded which can be used for feed, bedding and the like. The shredding attachment can be easily and quickly attached to a round bale hay baler at the front lower area thereof and is drivingly connected to the power system of the hay baler and includes a rotatable shaft having a plurality of pivotal flail elements or knives mounted thereon for shredding stubble or stalks and discharging the shredded material rearwardly and upwardly into the hay baler in the same manner that hay enters the hay baler with the shredded stubble being rolled into a hay bale in the same manner that hay is baled by the round bale hay baler.
